1 FEATURES AND REQUIREMENTS

1.1 THE 3100 EL2 DISTRIBUTOR

The 3100 EL2 Distributor is a two-speed electronic valve with: - the new Fluitronic digital technology. - the “Stepping System” device - the possibility to use ecological fluid or traditional mineral oil

Guarantees: - Increased reliability of the control system - Best performance - Reduction of costs - Reduction of consumptions - Reduction of the travel time - Reduced use of heat exchangers - Constant downward speed regardless of the load - Compliance with various regulatory and environmental requirements

(Ex. compliance with the Directive 2006/118/EC on the environment) Offers:

- Speed up to 1 m/s - Downward speed greater than the upward

(up to + 50% for flow rates ≤ 150 l / min, up to + 30% for flow rates> 150 l / min and ≤ 210 l / min.) - Adjustable maintenance speed up to 0.6 m/s - A reduction of the internal pressure drops of the distributor and a better energy efficiency, bringing a

reduction in the power of the motors compared to a traditional mechanical distributor. - An energy saving due to the fact that the distributor is not affected by changes in pressure and

temperature of the fluid and therefore does not need to be equipped with valve heating or oil heating resistances.

- The possibility to adjust electronically, independently and separately all the phases of the lift operation. - Integrated Soft Stop function (optional) - The possibility to adjust the distributor using the PT01 programmer. - The possibility to modernize the existing lifts equipped with a 3010 mechanical distributor without

changing the electrical system.

1.2 THE FLUID

GMV uses and recommends a hydraulic fluid ISO VG 46 that: - Thanks to classification as category HEES, as rule ISO-UNI 6743-4 and its

biodegradability index > 70%, according to standard OECD-301-B, is acceptable from an environmental point of view

- Thanks to the synthetic base (ISO VG 46) and its viscosity index (>140), higher than the traditional mineral oil, allowing greater stability, ensuring better performance against wear and aging on systems as lifts for persons and goods, in accordance with the environmental directive 2006/118/CE.

- Thanks to its flash point above 300°C compared to the 140°C of the traditional mineral oil it is safer and reduces the risk of fire.

1.3 MAIN FEATURES

Distributor type 3100 EL2 Minimum operating pressure 12 bar Maximum operating pressure 45 bar Maximum speed 1 m/s Temperature limits 5°C - 70°C Fluid flow rate 55 - 216 l/min

2.5.1 CONNECTION WITH HOSE

- Remove the gear and the cutting ring from the terminal connection of the silencer.

- Ensure that the terminal connection is well fixed on the silencer.

- Clean and oil the threading and their seats.

- Fix the hose verifying it is thoroughly tightened.

ATTENTION Ensure that there is no dirty inside the tube. These impurities could damage the sealing of the piston and of the distributor and inhibit the correct operation of the system.

2.5.2 CONNECTION WITH A RIGID PIPE

- Cut at 90° the head of the tube with a saw (do not use a tube-cutter) - Do not let metal residuals fall into the tube and eliminate the burrs internally and externally. - Remove the gear and the cutting ring of the terminal connection and insert it on the pipe. - Ensure that the cutting ring is inserted as indicated in image

- Ensure that the terminal connection is well fixed on the silencer.

- Clean and lubricate the threading and the connection seat with a slight oil veil.

- Insert the pipe into the cone at 24° up to lay it on the stop limit of the cone itself.

- Screw thoroughly the gear by hand until it is felt that the cutting gear lays perfectly to the nut.

- Then screw the nut using a wrench until the cutting edge of the ring is in contact with the tube and prevents it from rotating.

- Keep the tube against its stop to avoid it rotates, screw the fixing nut by 3/4 clampdown. In doing so the ring engraves with the necessary depth the external part of the tube and rises a border in front of its cutting edge.

- Loose the nut and check that the tube has all around a well risen border. The border must cover 70% of the front part of the cutting ring.

- Fix the tube, close the nut with a wrench until a certain resistance is felt; from this moment on screw for a further 1/4 turn, contrasting wrench against wrench.

ATTENTION Ensure that there is no dirty inside the tube. These impurities could damage the sealing of the piston and of the distributor and inhibit the correct operation of the system.

3 EL2 BOARD

3.1 MAIN FEATURES

The EL2 board manages the 3100 distributor by means of the stepping motor control that operates the VRF spool.

There are two ways to control the distributor by the control panel: - Parallel mode: all the commands are given through signals on specific inputs; - Serial mode: all commands, except the down command, are given via CAN bus

in CAN-open mode with NEOS systems. The hardware features of the EL2 board are:

# DESCRIPTION VALUE 01 Supply voltage 20 ÷ 27Vdc, 18 ÷ 24Vac 02 Protection (fuse F1) 2A 03 Voltage input 16...230Vdc / Vac 04 Voltage output (alarm relay), Volt free contact

according with EN81-20 for distances and insulation up to 250V 24...180Vdc / Vac 10mA@20Vdc / 2A@180Vac

05 Stepping motor Max 3A rms

3.2 HOW WORKS

The EL2 board controls the position of the VRF spool of the 3100 distributor to determine the speed of movement of the cabin.

The movements are determined by commands received in input and the movement curves are defined by a set of parameters.

STEPPING MOTOR AND VRF The VRF spool is moved by a screw fixed to a bipolar stepping motor controlled by the EL2 board. Il cursore VRF è azionato da una vite solidate ad un motore passo-passo bipolare comandato a sua volta

dalla scheda EL2. SWITCH ON AND AUTOMATIC CALIBRATION AT START-UP When the EL2 board is switched on, it automatically calibrates the zero position of the stepper motor (Start /

4.2 EXAMINATIONS AND TESTS BEFORE PUTTING INTO SERVICE

4.2.1 RUPTURE VALVE (VC) [EN81-20 §6.3.8]

ATTENTION - Before performing this test for the first time, make sure that the rupture valve on the cylinder is already calibrated or make its adjustment. (see technical report of the system and instructions of the rupture valve)

VC 3006 /B /G

To perform the rupture valve test, follow the procedure below: 1. Move the car with nominal load evenly distributed to the higher floor and wait for the car stop

and the doors close; 2. When the car has stopped, loosen the lock nut on the screw/tap (5) and close the screw/tap (5)

as far as it will go. 3. Move (Call) the car at the lower floor. The rupture valve, during downward, when the system

reaches the intervention speed, must stop the car and maintaining it stationary.

ATTENTION If the car does not stop, it is necessary to check / change the adjustment of the rupture valve following the instructions contained in its manual.

4. Checked that the rupture valve engages, completely loose the screw/tap (5) and tighten the lock nut; 5. Use the hand pump to unlock the rupture valve

4.2.2 RESTRICTOR/ONE-WAY RESTRICTOR (VC) [EN81-20 §6.3.9]

ATTENTION If a restrictor is installed on the cylinder, before performing this test for the first time, make sure that it is already calibrated or make its adjustment. (see technical report of the system and instructions of the restrictor)

VC 3006

/D /R

The test procedure is the same as for the rupture valve. An exception is point 3 in which, during the downward, the restrictor must not block the system but

limit its descent speed to the defined value.

4.2.3 PRESSURE TEST [EN81-20 §6.3.10]

This optional test assures you about the integrity of parts under pressure, including those which cannot be visually checked

To perform the test, follow the procedure below: 1. Open the shut-off valve (R/S) (position A). 2. Move the empty car to the highest floor and using the hand pump

(PAM) send the piston to the up stroke. 3. Open the pressure gauge tap (6) 4. Looking at the manometer (MAN), use the hand pump (PAM) until a

pressure equal to 200% of the maximum static pressure is reached. 5. Once the pressure is reached, observe the system for 5 minutes to

verify if there are pressure drop and leakage (leakages up to 10 bar are considered acceptable).

6. At the end of the test, press the button above the VMD to return the piston to normal stroke conditions and to reduce the system pressure.

7. Close the pressure gauge tap (6).


10991438 EN - 1.02 - 27.09.2019

4.2.4 PROTECTION AGAINST UNINTENDED MOUVEMENT [EN81-20 §6.3.13]

ATTENTION The 3100 EL2 distributor is able to control the unintended movement of the car only if installed together with the DLV A3 valve. Perform these tests only after performing the previous ones.

To check the correct behaviour of the devices against unintended movement, it is necessary to check that the control panel and the system work in compliance with EN81-20 §5.6.7.

4.2.4.1 PRELIMINARY REQUIREMENTS

As required by the EN 81-20 standard, the following must be respected: - The system must be equipped with at least one switch device capable of detecting the unintended

movement of the car. - The control panel must not send commands to the distributor and to the motor/pump unit when the

system is located, with doors not closed, outside the door unlocking zone.

NOTE Before proceeding, check on the manual of the electrical part the operations to be performed, necessary to carrying out the test.

6 MAINTENANCE

6.1 PROGRAMMED MAINTENANCE

For a correct and safe lift use, it is necessary to make a preventive programmed maintenance, following a fixed plan.

To define the periodical maintenance frequency, you should consider more events, particularly: - Number of travels per year - Travelling and stopping periods - Age and condition of the lift - Site and type of the building in which the lift travel - Passengers and goods demand - Inside and outside working condition (climate, vandalism, etc.)

In the next table, parts are shared in groups and for each group is shown the type of check and its longest frequency recommended. Checks operative instructions are detailed in the maintenance schedules on chapter.

Please, note that all checks are applicable only if the part is really installed.

6.2 PERIODICAL MAINTENANCE AND CHECKS TABLE

button (ML) on the DLV and the VMD. Contact GMV assistance to check the cleanliness of the

seal seats.

Furthermore, one or more of the following valves do not close correctly The downward solenoid valve (VMD) Turn off the power and close the shut-off valve (R/S).

Remove the VMD solenoid valve; check the sliding of the movable core (travel ~0.5 mm); check the cleanliness of the seal seats and the good condition of the ball.

The emergency lowering valve / push-button (VSMA / ML)

Turn off the power and close the shut-off valve (R/S). Remove the VSMA solenoid valve; check the cleanliness

of the seal seats and the good condition of the ball. Check the sliding of the emergency lowering button (ML)

The non-return valve (VRP) Turn off the power and close the shut-off valve (R/S). Remove the VRP spool and check the cleanliness of the

seal seats. If the gasket is damaged and/or worn, replace it. Reassemble the spool, checking that it slides well into its seat.

The non-return valve(s) of the hand pump (PAM)

Close the shut-off valve (R/S). Check the non-return valve for leaks by using the

handpump, that the overpressure valve (VS) is able to intervene

IX. The downward speed V0 is less than the V0 upward speed


Parameter 5.1 "V0 downward" < 4.1 "V0 upward"

Check that parameter 4.1 ≥ 5.1 and modify the values if necessary.

The adjustment screw (9) of the VRFP is too open.

Tighten the screw 9 one turn at a time until reaching the correct speed.

X. The hand pump does not work


The hand pump hose does not reach the fluid. Check that the end of the hand pump pipe is below the minimum fluid level

The hand pump is not primed. Loosen the air bleeder screw and pump until the fluid reaches the air bleeder.

Close the air bleeder screw and check that the hand pump works correctly (see below)

The hand pump does not work even after the exclusion of the two previous cases

Check that, with the shut-off valve (R/S) closed and the pressure gauge tap open, using the hand pump, the pressure indicated by the pressure gauge increases.

Otherwise contact GMV assistance.
