1 Safety

1.1 Risk potential of the oily water separator system The oily water separator has been subject to a safety inspection and acceptance test. Faulty installation or improper use can cause danger to life and limb of the installation staff, the oily water separator and other assets of the ship equipment, the efficient functioning of the oily water separator.

All persons involved in installing the electric and hydraulic supply of the oil separator must be qualified, and comply with these installations instructions.

1.2 Safety information and tips The following warnings are used in these installation instructions:

Danger

Denotes an immediate danger. Non-observance of this warning may result in death or severe physical injury.

Voltage Danger of crushing Danger of tumbling Hot surface

Warning

Denotes a potentially dangerous situation. Non-observance of this warning could result in death or severe physical injury.

Important

Denotes a potentially dangerous situation. Non-observance of this warning may result in minor physical injuries.

Information

Denotes notes for application and other useful information.

1.3 Proper use This system must be used according to the regulations by the IMO only for separating dis-persed or emulsified oil-water-mixtures!

Important

The system and the pump may not be used to pump oil or sludge. Pollution hazard!

1.4 Emissions The A-rated equivalent permanent sound pressure level of the oily water separator is below 70 dB(A).



1.5 Sources of danger

Danger

Electrical voltage > 42 V Direct contact with live parts can lead to severe injury or death. Before working on electric equipment, interrupt the voltage supply (main switch off, fuses removed or switched off).

Warning

The oily water separator operates with an eccentric spiral pump. Do not touch the rotating shaft in the area of the transmission bell housing / stuffing box packing! Danger of most severe finger injuries.

Warning

The valves item 4, 5 and 15, up to rated width R 1", are closed by means of a pre-tensioned spring. On dismounting the valve drive, the spring can eject forcefully and cause injuries.

Caution

The oil separator can be heated by a heater (electrically or e.g. by steam). In the upper area, temperatures up to approx. 50 degrees Celsius can occur. Danger of burns.

1.6 Safety measures at the point of installation The oily water separator must be erected stable on a flat and firm surface. A tumbling oily wa-ter separator causes risk of life.

2 Important technical information

Information

The RWO bilge water oil separator type SKIT/S DEB also meets the requirements of the class notation “Clean Design”. For this purpose the alarm point are set to: Alarm 2 5ppm (recirculation) and Alarm 1 4ppm (adsorber by-pass) (values in parentheses in the documentation)

The oil separator should be installed according to these installation instructions in order to operate trouble-free. RWO does not accept any responsibility for damages resulting from improper installation of the system.

We do not assume any liability for damages due to failure to comply with these installation instructions and improper use.

Comply with the connection voltage as indicated on the automatic control system. The oily water separator is designed for a water mix temperature between min. + 2°C and

max. 45°C.

Important

The oil-separation pump is designed to operate at a maximum temperature of 45°C. At temperatures higher than 45°C, excessive starting torque occurs in the motor due to thermal expansion of the materials of the rotating parts which means that the motor is in danger of being damaged beyond repair.

The rotational direction of the pump is "CLOCKWISE" when viewed from the motor.



Information

Dry running protection for bilge pump is not necessary: During op-eration of the pump the coalescer stage at suction side of bilge pump is filled up with water/oil. The bilge water inlet is fitted with a non-return valve which prevents the system from emptying. The bilge pump take suction direct from coalescer stage, so that dry running is impossible. The sensor electrode on top measures the oil level inside the coalescer unit. If there is no oil or/and no water the alarm device will be activated which stops bilge pump motor auto-matically and starts deaeration through the oil discharge valve.

Important

During commissioning! Incorrect sense of rotation causes the pump to run dry and can destroy the stator by overheating already after a few revolutions.

Compressed air 6-8 bar and flushing water with max. 4.5 bar are required for proper opera-tion of the oily water separator. The water flow pressure should not fall below 0.5 bar.

The system must be kept free from solid matter. Avoid emulsions!

Use separation-friendly cleaning agents. The lower the content of emulsified oil in the bilge water, the longer the service life of your adsorber elements.

If the installation point of the system can be subject to frost, the system must be completely drained after each use or be heated permanently.

Prior to commissioning clean pipelines and bilge.

3 Important general information The IMO Resolution MEPC. 107(49) has come into effect on 18th of July 2004 and refers to all bilge water separators and 15 ppm alarm devices installed on ships after the 1st of January 2005. The IMO Resolution MEPC.107 (49) describes details for the type test of oil separators and 15 ppm oil content alarm devices. the main difference to the old resolution MEPC.60 (33) lies in the fact that the new MEPC.107 (49) includes oil in water emulsions. The emulsion is gen-erated by mixing the different test oils with a specified emulsified chemical substance and an iron oxide powder under controlled conditions for an hour by means of a centrifugal pump with high speed. The bilge water oil separator must be capable of separating the emulsion and precipitate oil residue. An emulsion is a mixture of two or more components. In this case it includes oil and water. This mixture contains small oil particles which, however, do not form larger drops or connect to such. Generating an emulsion requires mechanical energy. This can be achieved by a ro-tary pump or by higher pressure and turbulent flow speed in a pipe system. In this process, present oil drops are divided into many very small oil particles. This type of mechanical emul-sion can easily be separated by means of an efficient coalescer. But if emulsifying chemicals are present, the oil particles become hydrophobe by means of ionic and anionic tensides on the oil particle surface. The same micro-electric load of all particles in a stable chemical emul-sion renders agglomeration impossible. Mechanic emulsions can normally be easily separated by means of a mechanic coalescer. Stable chemical emulsions can not be separated this way, however. Stable chemical emulsions can be separated by means of: heat treatment in a vaporiser chemical processes by using an adequate coagulation agent membrane - ultrafiltration which retains the oil molecules adsorption by means of suitable materials

3.1 Excerpt from the IMO Resolution MEPC.107(49) The following contains an excerpts from the IMO Resolution MEPC. 107(49). The excerpts are quoted in the original language (English). Revised Guidelines and Specification for Pollution Prevention Equipment for Machinery Space Bilges of Ships: Background

3.2 MARPOL 73/78 Annex I The requirements of Annex I of the International Convention for Prevention of Pollution from ships MARPOL 73/78 relating to pollution prevention equipment for ships are set out in regula-tion 16, which stipulates that shops of 400 gross tonnage and above should be installed with approved equipment

3.3 Regulation 16(5) Regulation 16(5) stipulates that the oil content of the 15 ppm Bilge Separators should not ex-ceed 15 ppm. The 15 ppm Bilge Alarm shall activate to indicate when this level cannot be main-tained and initiate automatic stop of overboard discharge of oily mixtures where applicable. 3.3.1 15 ppm Bilge Separator; 3.3.2 15 ppm Bilge Alarm 3.3.3 Automatic stopping device



3.4 MEPC.107(49) The Resolution MEPC.107(49) supersedes the recommendations contained in Resolution MEPC.60 (33).

3.5 Equipment requirements 3.5.1 Bilge separator 15 ppm Bilge Separators are considered to be applicable for use in conjunction with oily bilge-water and ballast water from fuel oil tanks, as these are of a low or medium capacity, and are conditioned by the need to avoid discharging oil mixtures with an oil content more than 15 ppm of the mixture. It should be understood that a 15 ppm Bilge Separator must be capable of han-dling any oily mixtures from the machinery space bilges and be expected to be effective over the complete range of oils which might be carried on board ship, and deal satisfactorily with oil of very high relative density, or with a mixture presented to it as an emulsion. Cleansing agents, emulsifiers, solvents or surfactants used for cleaning purposes may cause the bilge water to emulsify. Proper measures should be taken to minimize the presence of these substances in the bilges of a ship. With the possibility of emulsified bilge water always present the 15 ppm Bilge Separator must be capable of separating the oil from the emulsion to produce an effluent with an oil content not exceeding 15 ppm. 3.5.2 Bilge Alarm The 15 ppm Bilge Alarm should record date, time and alarm status, and operating status of the 15 ppm Bilge Separator. The recording device should also store data for at least eighteen months and should be able to display or print a protocol for official inspections as required. In the event the 15 ppm Bilge Alarm is replaced, means should be provided to ensure the data re-corded remains available on board for 18 months (computer unit). To avoid wilful manipulation of 15 ppm Bilge Alarms, the following items should be included: 1. very access of the 15 ppm Bilge Alarm beyond the essential requirements of paragraph 4.2.8

requires the breaking of a seal and 2. the 15 ppm Bilge Alarm should be so constructed that the alarm is always activated when-

ever clean water is used for cleaning or zeroing purposes. 3.5.3 Automatic stopping device The automatic stopping device is a device used, where applicable, to automatically stop any discharge overboard of oily mixture when the oil content of the effluent exceeds 15 ppm. The automatic stopping device should consist of a valve arrangement installed in the effluent outlet line of the 15 ppm Bilge Separator which automatically diverts the effluent mixture from being discharged overboard back to the ship's bilges or bilge tank when the oil content of the effluent exceeds 15 ppm. The accuracy of the 15 ppm Bilge Alarms should be checked at IOPP (International Oil Pollution Prevention) Certificate renewal surveys according to the manufacturers instructions. Alterna-tively the unit (measuring block) may be replaced by a calibrated 15 ppm Bilge Alarm. The cali-bration certificate for the 15 ppm Bilge Alarm, certifying date of last calibration check, should be retained onboard for inspection purposes. The accuracy checks can only be done by the manu-facturer or persons authorized by the manufacturer.



3.6 Installation requirements 15 ppm Bilge Separator For future inspection purposes on board ship, a sampling point should be provided in a vertical section of the water effluent piping as close as is practicable to the 15 ppm Bilge Separator outlet. Re-circulating facilities (manual 3 way valve) should be provided, after and adjacent to the over-board outlet of the stopping device to en-able the 15 ppm Bilge Separator system, including the 15 ppm Bilge Alarm and the automatic stopping device, to be tested with the overboard discharge closed (see Fig. 1). The re-circulating facility should be so configured as to prevent under all operating conditions any by-pass of the oily-water-separator. 15 ppm Bilge Separator should be based in a non-hazardous area.

3.7 Instructions A vessel fitted with a 15 ppm Bilge Separator should, at all times, have onboard a copy of the Operating and Maintenance manuals. All routine and repair maintenance to be recorded, see “Routine and repair maintenance record” Tabelle in “Operation and maintenance instruction”.

3.8 Training Ship staff training should include familiarization in the operation and maintenance of the equip-ment.

3.9 Applicability These guidelines and Specifications apply: to installations fitted to ships, the keel of which are laid or which are at a similar stage of

construction on or after 1 January 2005 and to new installations fitted on or after 1 January 2005 to ships, the keel of which were laid or

which were at a similar stage construction before 1 January 2005 in so far as is reasonable and practicable

3.10 Separation-friendly cleaning agents Cleaning agents often cause stable emulsions in oil-water mixtures which cannot be sepa-rated by gravity and coalescence. We carried out extensive test runs with different cleaning agents under conditions that were as close to normal operation as possible. From the vast range of cleaning agents on the market, we tested some products out of which the following agents have proven to be relatively suitable for use in our systems:

1. Drewclean 2000, Drew Ameroid Marine Division Ashland Chemical, Inc 2. Tegeral Des Flüssig, Tegee-Chemie GmbH 3. Tegeral Forte, Tegee-Chemie GmbH 4. Carclin Außenreiniger F, Henkel KGaA 5. Carclin Veri, Henkel KGaA

3.11 Type test The type test for the 15 ppm bilge water oil separator and the 15 ppm alarm monitor has been carried out successfully and in compliance with the IMO Resolution MEPC. 107 (49) Annex.

4 Process description of RWO bilge water oil separator type SIKT/S DEB The RWO bilge water oil separator type SKIT/S DEB meets the requirements of the latest IMO Resolution MEPC. 107 (49). The function bases on the operation principle of the open porous coalescer which has already been proven and tested in the oil separator system SKIT/S. In a second stage, the system breaks up the emulsion and removes the oil from the emulsion.

4.1 Oil water separation An eccentric spiral pump (item 14) draws the mixture through the SKIT aquaclean "S-DEB" out of the bilge. This flow conduction avoids unnecessary additional mixing of oil and water due to pump turbulences upstream of the gravity oil separator. The 1st stage of the SKIT aquaclean "S-DEB" comprises much improved rough separation using the different densities of water and oil. A very open porous coalescer causes, due to its extremely oleophile surface, fine separation of even the smallest oil drops. This system provides excellent efficiency of the SKIT aquaclean "S-DEB" oil separator.

4.2 Adsorber bypass The adsorber bypass is controlled by the bilge alarm monitor OMD (see P&ID). The adsorption elements remove all types of hydrocarbons from the water. The adsorption capacity is mainly limited by the amount of hydrocarbons in solution or emulsified in the water, but larger amounts of dirt particles can also block the adsorber. To increase the adsorber ser-vice life, avoid heavy emulsions with high oil concentration by using quickly separating clean-ing agents in the engine room. Emulsions from compressor condensate and cleaner sludge should be collected separately. If mixed into the bilge water, most of these emulsions are hard to break and could reduce adsorber lifetime significantly. In order to increase the service life of the adsorber cartridges, an automatic adsorber bypass has been installed. The 15ppm (5ppm) oil alarm monitor checks the water quality periodically



(every 5 minutes for 4 seconds) at the outlet of the first oil separator stage. If the value at this measuring point is below 14ppm (4ppm), the bypass valve (item 58) guides the cleaned water directly outboard, bypassing the adsorber. If the value is above 14ppm (4ppm), the adsorber stage is activated. This process control ensures a significantly increased service life of the ad-sorber cartridges. During the short measuring period (4 seconds), the 3-way valve (item 23) guides the cleaned water back to the bilge / bilge tank for security reasons. This type of control ensures that only cleaned water with less than 15ppm (5ppm) residual oil content can get outboard. By factory default, the alarm threshold value 2 is set to 15ppm (5ppm) and the alarm threshold value 1 to 14ppm (4ppm). Only if the residual oil content of 15ppm (5ppm) is exceeded for at least 2 seconds, an alarm message to the engine control room is activated. Alarm 1 must be set to a lower value than alarm 2. In principle, three control states are possible: a) The measuring point falls below the limit value set for alarm 2 (15ppm (5ppm)) and the measuring point falls below the limit value set for alarm 1 (14ppm (4ppm)). Operation without adsorber, cleaned water is guided outboards. Voltage is applied to the solenoid valve of the 3-way valve (item 58). The 3-way valve (item 58) guides the water bypassing the adsorber. Voltage is applied to the 3-way valve (item 57) which guides measuring water from the measuring point upstream of the adsorber to the oil alarm monitor OMD. Voltage is applied to the solenoid valve of the 3-way valve (item 23). The 3-way valve (item 23) guides the water outboards. The display of the control system indicates: b) The measuring point exceeds the limit value set for alarm 1 (14ppm (4ppm)) and the measuring point falls below the limit value set for alarm 2 (15ppm (5ppm)). Operation with adsorber, cleaned water is guided outboards. No voltage is applied to the solenoid valve of the 3-way valve (item 58). The 3-way valve (item 58) guides the water through the adsorber. No voltage is applied to the 3-way valve (item 57) which guides measuring water from the measuring point downstream of the adsorber to the oil alarm monitor OMD. Voltage is applied to the solenoid valve of the 3-way valve (item 23). The 3-way valve (item 23) guides the water outboards. The display of the oil separator control system indicates: c) The measuring point exceeds the limit value set for alarm 1 (14ppm(4ppm)) and the measuring point exceeds the limit value set for alarm 2 (15ppm (5ppm)). Operation with adsorber, cleaned water is guided back to the bilge / bilge water tank. No voltage is applied to the solenoid valve of the 3-way valve (item 58). The 3-way valve (item 58) guides the water through the adsorber. No voltage is applied to the 3-way valve (item 57) which guides measuring water from the measuring point downstream of the adsorber to the oil alarm monitor OMD. Voltage is applied to the solenoid valve of the 3-way valve (item 23). The 3-way valve (item 23) guides the water back to the bilge / bilge water tank. The display of the oil separator control system still indicates and the oil separator keeps operating. Additionally an alarm message to the engine control room is activated. On the monitor, two red LEDs signal that both limit values are exceeded which constitutes an alarm.

4.3 Flushing In the upper calming zone of the oil separator the separated oil is collected. The RWO sensor electrode (item 9) measures the cumulative oil level. As soon as a specified amount of oil has been collected, the RWO automatic level system (item 3) opens the oil drain valve (item 4) and the flushing water inlet valve (item 15) so that the oil is discharged to the oil collector tank by means of the flushing water pressure. This stage is followed by the backflush process. The high-performance coalescer is flushed with clean water by opening both the flushing water inlet valve (item 15) and the flushing water outlet valve (item 5). The oil separation interval and the flush cycle are aligned in such a way to allow the SKIT aquaclean "S" to operate maintenance-free.

4.4 Bilge alarm monitor OMD The oil separator system is equipped with a 15ppm (5ppm) oil alarm monitor OMD. The de-vice has been tested in compliance with IMO Resolution MEPC.107 (49). The new resolution requires: The excerpts are quoted in the original language (English). The oily water separating system is equipped with the 15ppm oil content alarm device OMD, type tested and approved in accordance with IMO Resolution MEPC.107 (49). The new resolu-tion requires:



The 15ppm Bilge Alarm should record date, time alarm status and operating status of the 15ppm Bilge Separator. The recording device should also store data for at least eighteen months and should be able to display or print a protocol for official inspections as required. In the event that the 15ppm Bilge Alarm is replaced, procedures should be put in place to ensure the recorded data remain accessible on board for 18 months. To prevent tempering with the 15ppm Bilge Alarms, the following precautions should be taken: Every access of the 15ppm Bilge Alarm beyond the essential requirements of paragraph

4.2.8 of the MEPC.107(49), requires the breaking of a seal. The 15ppm Bilge Alarm should be so constructed that the alarm is always activated when-

ever clean water is used for cleaning or zeroing purposes. The Bilge Alarm Monitor OMD complies with the above rules. The measuring cell can be re-moved for calibration while the control device remains on the oily water separator to keep the recorded data on board for at least 18 months. A 3-way valve for flushing is fitted with a contact to ensure that during flushing of the alarm monitor an overboard discharge of polluted water is not possible.

5 Operation of the system

5.1 Prior to commissioning

5.1.1 Check electric connections

Danger

Electrical voltage > 42 V Direct contact with live parts can lead to severe injury or death. The fixed connection to the mains supply may only be established by qualified staff (electrician)

Danger

Risk of explosion Standard systems may not be operated in explosive areas

5.1.2 Checking tube and flange connections

Caution

Lines under pressure bear the risk of injuries. Prior to work on water and compressed air lines check and ensure that these are pressure-free.

Important

The SKIT S-DEB operates in suction mode. Make sure that the oil separator does not draw air via leaks in the suction line and/or flange connections of the oil separator container. Drawn air causes perma-nently repeated flushing processes. The oil separator can then not draw any wastewater and thus not perform the water oil separation properly.

5.1.3 Check for presence of wastewater.

Important

The indicator lamp "Bilge level" is designed as optical indicator for the presence of wastewater. By factory default, the oil separator is delivered with two bridges be-tween the terminals X2-4 and X2-5 and the terminals X2-6 and X2-7. The oily water separator can only start operation in bridged state. We recommend to replace these bridges by two floating switches (upper and lower level switch) in the bilge or the bilge water tank and to use those switches for level-dependent control of the oily water separator. To achieve this, both floating switches must operate as normally open contact. When the level rises, both switches must close one after the other, only the oily water separator is supposed to start. When the level falls, both switches must open one after the other, only the oily water separator is supposed to stop.



5.1.4 Ensure compressed air supply of approx. 6-8 bar and flushing water supply of max. 4.5 bar.

5.1.5 Open the valves in the suction line.

5.1.6 Open the valves in the clean water line towards outboard.

Important

The pump is a displacement pump; it must not be operated up-stream of closed fittings.

5.1.7 Check the sense of rotation of the pump.

Important

Upon restart or after a longer standstill, make sure that the drive motor can turn the pump without problems. Should this prove to be impossi-ble, e.g. because of the high adhesion between rotor and stator in new condition, you can support this movement using a suitable tool at the shaft behind the shaft seal.

Warning

Do not touch the rotating shaft in the area of the transmission bell hous-ing / stuffing box packing! Danger of most severe finger injuries.

Important

The rotational direction of the pump is "CLOCKWISE" when viewed from the motor. If the rotational direction is incorrect, there is acute danger that the pump will run dry! The pump must never run dry, this must be avoided at all costs! If the rotational direction is incorrect, the pump can run dry and damage the stator even after just a few revolutions! You can avoid this danger by ensuring that the rotational direction is correct. The control system will only start the pump once the oil-separator housing is filled with water.

5.1.8 Check the pressure gauge. The pressure gauges are equipped with a glycerine discharge protection. To enable pressure compensation in the pressure gauge housing, cut off the nipple at the upper rubber cap before commissioning.

5.2 Before putting into operation.

5.2.1 Check for presence of wastewater.

Important

The indicator lamp "Level" is designed as optical indicator for the presence of dirty water. See also the detailed description in section 5.1.3

5.2.2 Ensure compressed air supply and flushing water supply.

5.2.3 Open the valves in the suction line.

5.2.4 Open the valves in the clean water line towards outboard.

Important

The pump is a displacement pump; it must not be operated up-stream of closed fittings.

5.3 Putting SKIT/S-DEB into operation

Danger

Electrical voltage > 42 V Direct contact with live parts can lead to severe injury or death. The fixed connection to the mains supply may only be established by qualified staff (electrician)

The 4 LEDs in the control box door indicate the basic functions. The oily water separator can be started and the operational modes selected by a main switch and the switch "Hand"-"Zero"-"Auto". There are terminals for two level switches in the bilge. With such switches in-stalled and automatic mode acti-vated, the system can start or be switched off depending on the level. By factory default, the terminals for the floating switches are bridged.

Figure 2 shows the control ele-ments of the automatic control:

Decide whether to operate in "manual mode" or "automatic mode".

Information

In "manual mode", the oily water separator operates independent of the level switch signals in the bilge. The oily water separator does not switch off automatically according to the level. Therefore you should only select this operation mode if the system is under permanent supervision.

Switch on the main switch "POWER". The indicator lamp "RED-OILDISCHARGE" illuminates in red (oil to the collector tank) be-

cause the sensor electrode signals air as well as oil (both media are not conductive). The pneumatic piston valves at the flushing water inlet (item 15) and oil outlet (item 4) are open (voltage is applied to both solenoid valve) and the system is automatically filled with flushing water and at the same time vented through the oil outlet. The pump remains switched off in this process.

As soon as the water level reaches the sensor electrode (item 9) (conductive medium de-tected), the indicator lamp switches to "ORANGE-FLUSHING" (backflush). The pneumatic piston valve (item 5) opens (voltage is applied to solenoid valve). With a given delay, the oil outlet valve (item 4) closes (no voltage applied to the solenoid valve).

As soon as the system is filled, the piston valves (items 5 and 15) close (no voltage applied to either solenoid valve). The indicator lamp "GREEN WATERDISCHARGE" at the auto-matic control box illuminates green (water outboards). Now the pump starts and draws from the bilge. The system is then ready for operation.

Now you can switch on the heater using the switch "Heater".

5.5 Check list for putting into operation, Table 4 The centre column is intended for the result mark "OK" Starting procedure OK Remarks Open valve(s) in the compressed air supply. Pressure 6-8 bar. Open valve(s) in the flushing water supply. Pressure max. 4.5 bar. Open valve(s) in the suction line. The suction line must be airtight because the

oil separator operates with negative pressure. Open valve(s) in the outboard line. The pump is a displacement pump; it must

not be operated upstream of closed fittings. Check rotational direction of the pump The rotational direction of the pump is

"CLOCKWISE" when viewed from the motor. Incorrect rotational direction bears danger of the pump running dry!

Open the tap of the adsorber housing cover until the adsorber is filled with water Cut off the rubber nipples of the caps on all pressure gauge housings

so that pressure compensation becomes possible

Check if cooling air can exit through the ventilation grid of the motor's ventilation flap.

This ensures proper motor cooling.

Table 4 Check list for putting into operation



6 Maintenance

6.1 Regular inspections Check the pressure difference upstream (pressure gauge item 8, on the oil separator cover)

and downstream of the coalescer (pressure gauge item 8, bottom, in front of the pump). The pressure difference may not exceed 0.2 bar. - Flush the coalescer

Information

Pressing the buttons (+) and (-) simultaneously for 2 seconds starts an oil simulation. After releasing the buttons the flushing process starts.

If this does not prove to be successful, replace the coalescer. Check the pressure difference upstream (pressure gauge item 54, downstream of the pump)

and downstream of the adsorber (pressure gauge item 54, upstream of the 3-way valve item 23). The pressure difference may not exceed 0.3 bar. - In case of exceeding values, replace the adsorber elements

Check the stuffing box packing of the pump. - A slight leakage (one to two drops per minute) is desired - Intensive leakage: -> retighten the nuts of the stuffing box frame slightly

(see operation and maintenance instructions of the eccentric spiral pump, section 2.3) If this does not prove to be successful, replace the stuffing box packing. (see operation and maintenance instructions of the eccentric spiral pump, section 3)

On the suction side of the pump, check the negative pressure indicated by the pressure gauge (item 8, bottom, in front of the pump). The minimum value to be reached must be the actual suction height between bilge level and oil separator as negative pressure in meter wa-ter column. - If this is not the case, check stator and rotor - If necessary, replace worn-out components

(see operation and maintenance instructions of the eccentric spiral pump, section 3)

6.2 Semi-annual inspections Check the zinc anode

- If necessary, replace the zinc anode Check the oil level if the pump gear motor

- If necessary, fill up oil (see operating and maintenance instructions of the gear motor)

6.3 Annual inspections Open the inspection port of the oil separator housing, the oil separator housing and the ad-

sorber housing Check for sludge deposits

- If necessary, remove the sludge and clean the container Check the inner coating

- Of necessary, mend damaged spots. Checks seals and piston valves

- If necessary, replace damaged seals and components. Check and clean the sensor electrode (item 9). If necessary, replace it. Check the function of the heater (item 10). If necessary, replace it.

8 Troubleshooting

8.1 Warning notes

Danger

Electrical voltage > 42 V Direct contact with live parts can lead to severe injury or death. Before working on electric equipment, interrupt the voltage supply (main switch off, fuses removed or switched off).

Warning

Lines under pressure bear the risk of injuries. Prior to work on compressed air lines check and ensure that these are pressure-free.

Warning

The oily water separator operates with an eccentric spiral pump. Do not touch the rotating shaft in the area of the transmission bell housing / stuffing box packing! Danger of most severe finger injuries.

Warning

The valves item 4, 5 and 15, up to rated width R 1", are closed by means of a pre-tensioned spring. On dismounting the valve drive, the spring can eject forcefully and cause injuries.

Caution

The oil separator can be heated by a heater (electrically or e.g. by steam). In the upper area, temperatures up to approx. 50 degrees Celsius can occur. Danger of burns.

9 Operating instructions for programmable oil separator control (as of software version 1.8)

9.1 General: Operation of the oil separator control involves 4 buttons. The backlit display has two lines with 20 characters each. The operational modes are displayed with 4 LEDs.

9.2 Elements of the control and display field a) On - Off – Main switch

Switch for the supply voltage of the oily water separator (on or off) b) Hand – 0 – Auto – Switch

Switch for the operation mode of the oily water separator control (manual, zero or automatic operation).

c) Position "Hand" The oily water separator operates independently from the level in the bilge or bilge water tank.

d) Position "Zero" The oily water separator does not operate.

e) Position "Automatic" The oily water separator starts automatically when the level in the bilge or bilge wa-ter tank switches the upper level sensor and stops automatically when the level switches the lower level sensor.

f) On - Off – Switch electric heater (optional) If the oily water separator is equipped with an electric heater, this button switches it on or off.

9.3 LEDs The display contains 4 LEDs which permanently indicate special operating states. Some of the 4 LEDs are multicoloured. a) White LED (Power)

Indicates readiness for operation. This LED illuminates as soon as the voltage sup-ply of the control is activated and the control is ready for operation.

b) Red LED (Failure) This LED indicates a failure state. The cause of the failure can be found on the dis-play.

c) Red/orange/green LED (Status) This LED indicates the operational state of the oil separator. Green indicates oil separation in progress. Red indicates oil discharge in progress. Orange indicates flushing in progress.

d) Green LED (Bilge level) The green LED indicates that the level in the bilge tank is high and that the oil sepa-rator can start operation.

9.4 Buttons The control panel comprises 4 buttons. With these buttons you can enter information and query operating states. a) ESC button

This button is enabled in all operating states. It serves to undo the previous opera-tion stepe. In the menu structure, pressing the ESC button exits one menu level and returns to the previous menu level. All settings remain. After pressing the button re-peatedly, you reach the start level, the operating status display.



b) - button, +button With these buttons you can modify settings. They are only active in the menus in which settings can be defined. They can be identified by words or numbers high-lighted by flashing. If words are highlighted, select the left word with the –button. Ac-cordingly select the right word with the +button in these menus. If numbers are high-lighted, you can set them by the digit with the -/+ buttons. To jump from one digit to the other, use the Enter button (see below).

NOTE! A special function allows for an oil simulation with the -/+ buttons. Press both buttons simultaneously for at least 2 seconds to run an oil simulation. The evaluation elec-tronics receives a fake interruption signal at both electrodes.

c) Enter button The Enter button serves as "Continue" or "Confirm" button. In the menu structure, pressing the Enter buttons switches to the next menu item or confirms a selection done right before with the –/+ buttons.

9.5 LCD The twenty-digit, two-line LCD can dis-play operating states and menu guid-ance either in German or in English. The start message shows: RWO Water Technology and a software version number. The display motherboard contains a potentiometer to adjust the contrast of the LCD to the lighting conditions.

The first line contains 4 numbers separated by points. The value range of each number is between 0 and 102. The first two numbers belong to the two analogue in-puts of the sensor electrodes and mirror the percentage threshold of the input pa-rameter for maximum modulation. In case of a 0-10V input, the value 48 indicates approx. 4.8 V. The 3rd and 4th digit mirror the resistance measured by the sensor electrode inputs. 0 indicates no or very low resistance (water). High numbers (e.g. 65) indicate a high resistance (oil).

Important note! The threshold value of the sensor electrode is pre-set by factory default to common

bilge waters and oils, normally it does not need to be adjusted. If special cases on board require an adjustment to different conditions, contact RWO service first. The second line contains the On/Off state of the inputs, indicated by 0 or 1. A total of 16 input data are displayed. For better overview, the 16 data are separated by points into blocks of 4. 14 of the 16 data derive from input 1 to 14. The last two input data derive from the sensor electrodes. If the measured resistance exceeds the threshold for oil detection, the input is shown as "1". If the measured resistance is below the threshold for oil detection, the input is shown as "0".

f) Notes on the output image: AUSGANG: 1000.0111.00

If the password is correct, the display jumps to the user settings level, and there to the query to change the first parameter. The selected default response is "NO". Pressing the Enter button therefore automatically jumps to the next parameter. That change query is also set to "NO" by default. This way, you can quickly navigate to the parameter you want to modify. (If you accidentally skip the desired parameter, you can press the ESC button once while still in the user settings. This will go back one level in the menu and thus to the query if you want to change user settings. If you answer this question with "Yes", you get back to the beginning of the user settings.)

After the last parameter you leave the user settings level and go back to the main level. The next stage in the main level is the question about changing factory set-tings.



h) Changing user settings If you navigated to the user settings as described above, you must select "YES" for every single parameter you want to change (+button). For example for the oil detec-tion threshold, this means:

WARNING! The values for oil and water detection must not be changed without consult-ing RWO service! Incorrect settings can cause severe functional failures!

See Important note under 9.6.e OEL-ERKENNUNG > % AENDERN? NEIN JA

OIL IDENT > % MODIFY? NO YES

After pressing the Enter button, the set value and the possible value range are dis-played. The first digit of the value flashes and can be modified with the -/+buttons. The process is the same as in entering the password.

OEL-ERKENNUNG > % WERT :055 (000..100)

OIL IDENT > % VALUE:055 (000..100)

WASSER-ERKENNUNG > % WERT :048 (000..100)

WATER IDENT > % VALUE:048 (000..100)

After entering the last digit and pressing the Enter button, the display prompts for confirmation to save the new value. OEL-ERKENNUNG > % SPEICHERN? NEIN JA

OIL IDENT > % STORE? NO YES

Use the -/+buttons to switch to "YES". Pressing with Enter button will confirm the new value (if the entered value is beyond the permissible range, it will automatically be set to the limit value). This exits the function to change this setting, the next user setting is queried for changes. You can cancel the changes to the user settings any time without changes by press-ing the ESC button. The menu then goes up to the level where the prompt asks for changes to the user settings. SPUELZEIT SEK. AENDERN? NEIN JA

FLUSHING TIME SEC. MODIFY? NO YES

The flush times depend on oil separator output and factory settings: SKIT 0.1 0.25 0.5 1.0 1.5 2.5 5.0 10.0 sec. 8 12 15 20 25 30 40 50

LANGZEIT ALARM MIN. AENDERN? NEIN JA

LONG TIME ALARM MIN. MODIFY? NO YES

The set value results from the maximum bilge water volume on board; it can be cal-culated by this formula: Minutes = maximum bilge water volume in m3 divided by pump output in m3/h * 60 plus 15 %. If the oil separator has not processed the bilge water within that time, the LONG TIME ALARM is triggered. Search for the cause, e.g. a leak in the suction line. The oil separator would then permanently suck air.



These displays to select changes, set values and save values are available for every user setting. The only exception is the item "Restore defaults". WERKSEINSTELL. HOLEN. AENDERN? NEIN JA

RESTORE DEFAULTS. MODIFY? NO YES

If you select "YES" in the item "Restore defaults", you will not see a submenu to set the values. Instead all parameters (except the flush time) are set to the general ini-tialisation settings.

Important note! If you had set values (e. g. for LONG TIME ALARM) individually, these must be set again to the previously set values after selecting "Restore defaults". In general: If you have changed user settings or restored the default, the control software must be reset by switching the system off and then on again accept the changes.

9.7 Control functions a) Oil detection and oil discharge

In the upper calming zone of the oil separator the separated oil is collected. The RWO level automatic measures the accumulated oil level with a three-rod sensor electrode (item 9). During the oil collection phase, the status LED is green. As soon as a specified amount of oil has been collected, the RWO automatic level system (item 3) opens the oil drain valve (item 4) and the flushing water inlet valve (item 15) so that the oil is discharged to the oil collector tank by means of the flush-ing water pressure. During this time, the status LED is red. This stage is followed by the backflush process. The high-performance coalescer is flushed with clean water by opening both the flushing water inlet valve (item 15) and the flushing water outlet valve (item 5). During this time, the status LED is orange. If the RWO automatic level system detects an illogical signal input, e. g. the short rod electrode detects a conductive medium (water) while the long rod electrode detects a non-conductive medium (oil), the system switches to standby mode and activates the alarm output. The oil separation interval and the flush cycle are aligned in such a way that the SKIT aquaclean "S-DEB" can operate largely without requiring attendance and main-tenance. During oil discharge and flushing, the pump (item 14) and the optional electric heater (item 10) switch off automatically!

b) Additional control functions b) 1 Level detection in the bilge or the bilge water tank (option) By factory default, the terminals X2-1 and X2-2 as well as X2-3 and X2-4 are bridged. To enable level detection, two level switches must be connected instead of the bridges. Oil separation starts and the green LED (bilge level) illuminates when the bilge water level has reached the upper level switch. When the bilge water level has reached the lower level switch, oil separation stops and the LED (bilge level) goes off. If the control unit detects an illogical signal input, e.g. upper level present and lower level not present, the system switches into standby mode and activates the alarm output.

Important note! If the level control is to be implemented with one floating switch only, remove both bridges. The level switch must be connected as NOC to terminals X2-1 and X2-2, additionally set a bridge between X2-2 and X2-4.



b) 2 Oil separator remote control (option) By factory default, the terminals X2-5 and X2-6 (NC) are bridged. The user can con-nect a remote switch "On - Off” or "Emergency Stop” there. These can switch the system into standby mode. b) 3

b) 3 a. Oil tank overflow (option) with software variant OP000 / OP001 / OP002 or OP003 activated! By factory default, the terminals X2-7 and X2-8 (NC) are bridged. The user can con-nect a level switch there. In case of oil tank overflow, the system switches into standby mode and activates the alarm output.

b) 3 b. Monitor flow controller (alternatively option) with software variant OP004 / OP005 / OP006 or OP007 activated! By factory default, the terminals X2-7 and X2-8 (NC) are connected to the flow con-troller. In case of insufficient flow, the display shows a corresponding message and the alarm output is activated. b) 4 Oil alarm by means of capacitive probe in the oil separator (option) By factory default, the terminals X2-9 and X2-10 (NC) are bridged. Optionally you can install and connect a capacitive probe in the oil separator. If special oils in the bilge water (e. g. hygroscopic oils) are not detected by the conductivity probe, the oil separator will slowly fill with oil. Once the oil layer reaches the capacitive probe it switches into standby mode and activates the alarm output. b) 5 Pressure difference switch (option) By factory default, the terminals X2-11 and X2-12 (NC) are bridged. The user can connect a pressure difference switch there. If the maximum pressure difference, e.g. between upstream and downstream of the adsorber, is exceeded for at least 10 sec-onds, the system switches into standby mode and activates the alarm output. This state requires a reset (selector switch in "0" position). b) 6 Dry run protection (option) By factory default, the terminals X2-13 and X2-14 (NC) are bridged. The user can connect a dry run connection for the oil separator pump there. When the dry run pro-tection triggers, the system switches into standby mode and activates the alarm out-put. b) 7 Oil monitor By factory default, the limit value signal 1 (set by default to 14 ppm (4ppm)) is con-nected to terminals X2-15 and X2-16, and limit value signal 2 (set by default to 15ppm (5ppm)) to terminals X2-17 and X2-18. Both signals serve for controlling the recirculation valve (item 23) and the valves (item 57 and item 58) for an adsorber bypass. If the value falls below limit value 1 and limit value 2

The valve for sample water (item 57) is switched to guide the water upstream of the adsorber to the monitor. The bypass valve (item 58) is switched to guide the water downstream of the oil separator bypassing the adsorber. The recirculation valve (item 23) is switched to guide the cleaned water out-board.

If the value exceeds limit value 1 and falls below limit value 2 The valve for sample water (item 57) is switched to guide the water downstream of the adsorber to the monitor. The bypass valve (item 58) is switched to guide the water downstream of the oil separator through the adsorber. The recirculation valve (item 23) is switched to guide the cleaned water out-board.



If the value exceeds limit value 1 and limit value 2 The valve for sample water (item 57) is switched to guide the water downstream of the adsorber to the monitor. The bypass valve (item 58) is switched to guide the water downstream of the oil separator through the adsorber. The recirculation valve (item 23) is switched to guide the cleaned water back to the bilge.

c) Alarms All alarm states activate a collective alarm relay. The display shows the different alarms as text. Potential-free changeover contacts X1-14, X1-15 and X1-16 can be used for an alarm signal.

d) System status message If these requirements are met: "Oily water separator switched on" and "Hand – 0 – Auto is not on Zero" and "Level in the bilge tank is high" and "Alarm states (except 15ppm / 5ppm* – Alarm) are not present", two relays are activated. The user can connect a remote indication light of the system status. Terminal X1-20 and X1-21 (ready connected by RWO) provide an operation

signal to the oil monitor which logs the oil separator operating hours.
