Safety

Terminology

Performance Specifications and Operational Limits



Safety Safety is a major concern when working around moving propellers. Extreme caution must be observed when working on or around the Q/Z-1250. The Q/Z-1250 propellers can rotate at more than 3,000 RPM and produce 300 W (0.4 HP) each.

There is extreme danger of injury if the propellers are touched while operating. Always stay clear of the propellers when the batteries are onboard.

The power switch can be depressed (aft deck of boat) to immediately cut power to the motors in an unex-pected event.

When powering up the Q/Z-1250, always turn the radio transmitter on BEFORE powering the boat itself.

If, when powered up, the receiver on the boat does not detect a controller signal, the Vessel Control Unit may unexpectedly enter the fail safe mode. This could be extremely dangerous, depending on the failsafe setting. The Q/Z-1250’s default failsafe behavior is to stop both propellers until RC contact is reestab-lished, but may be customized in the field to apply power to one or both propellers

When shutting down, always power down the boat (using the red battery switch) BEFORE shutting down the transmitter.

Again, if the transmitter is shut off before the boat, unexpected and possibly very dangerous maneuvers may occur.



Terminology Q/Z-1250 systems are comprised of the following components:

Tri-Hull boat

• Made of ABS plastic, the Q/Z-1250 is strong and robust to cope with the worst deployment conditions. All required cabling, batteries, and antennae are included for easy plug-and-play operation. Electron-ics are located below deck in a watertight compartment. Doppler profilers of 6.5” (165 mm) diameter or less may be used with adaptor mounts.

• Two 24 VDC Teledyne Seabotix brushless outdrive motors.

Hitec Aurora 9 Remote-Control System

• Hand held remote transmitter with LCD display for adjusting control settings.

• Paired transmitter receiver receives steering and motor control commands from the transmitter and sends battery voltage telemetry data back to the transmitter.

• Throttle and steering response characteristics may be adjusted using EPA menu.

Antennae

• Two RC system antennas connected to the receiver to provide redundant operation.

• Optional power/telemetry module includes an additional 2.4GHz, 5dBi antenna for Bluetooth com-munication.

4. Connect the GPS cable to the GPS receiver and to the Power/Telemetry module.



Battery Installation and Charging The Q/Z-1250 uses three 24 VDC, 4.5 AH battery packs connected to the electronics by red / black “An-derson” connectors. Battery life is highly dependent on boat and water speed. This set of 3 battery packs should last for approximately four hours at 2 kts (1 m/sec), at least 1.5 hours at 3 kts, and approximately 40 minutes at 4 kts (combined boat and water speed).

It is recommended that three battery packs are used in the Q/Z-1250 at all times to ensure adequate power reserves are available. This also provides security in case one or more packs are defective / poorly charged.

The batteries are installed in the battery compartment with the thermistor connector and wiring routed safely out of the way; make sure ALL THREE connectors are accessible. Care must be taken when con-necting the batteries. Ensure that the connectors are clean and the “Anderson” terminals are properly in-terlocked. Periodically inspect the metal terminals inside the connectors. It is good practice to measure the 3x individual battery cell voltages before and after the survey to ensure all cells are discharging to a similar voltage which indicates a good status. The Hitec transmitter may be used as a voltmeter to meas-ure individual battery voltage before and after surveys by connecting one battery at a time and noting the displayed voltage on the LCD panel. Ensure that no battery wiring is trapped between the battery com-partment and cover, and then tighten the six battery cover thumbscrews uniformly to create a watertight seal. Periodically check the O-ring in the battery compartment cover and replace if damaged.

Charging the Batteries The Q/Z-1250 is normally equipped with three 24V 10Ah NiMH battery packs and a smaller battery pack inside the handheld RC transmitter. It is important that the user fully charge each battery system before deployment.

The propulsion batteries’ operating endurance between charges ranges from 30 minutes to four hours, depending on operating speed and use of steering.

Once each month, the propulsion battery(s) should be fully discharged before recharging to avoid memory problems that may be caused by repeatedly charging partially discharged batteries.

To charge the batteries:

1. Disconnect all shipboard connections to the batteries and remove the batteries from the boat.

2. Place the batteries in a well-ventilated area away from flammable hazards ensuring the batteries are spaced sufficiently to allow proper airflow during charging.

3. Connect the small red thermistor connector on the battery to the opposite red thermistor connec-tion on the charger.

4. Connect the battery connector to the opposite connector on the charger. Insure that polarities are correct (black-black, red-red). Plug each 24V smart charger into an acceptable wall unit; the charger’s LED will flash red a couple of times then shift to solid red. NOTE: if the charger is plugged into a wall outlet prior to connecting the battery, it may not switch into a charging state automatically and the LED may remain green. If that occurs, unplug the charger from the wall un-til the green LED fades off, and then plug it back into the wall.

5. When charging is complete the LED will change to illuminate green.

6. Do NOT overcharge the batteries. Batteries should be supervised while charging and should not be left unattended. Ensure the batteries are disconnected as soon as charging is complete.

7. Under rare circumstances, the charger may finish the charging cycle prematurely before the bat-tery has been fully charged. Verify that the battery has been fully charged by measuring the volt-ages across each of the 3 discharge terminals. All voltages should be roughly equal and should be higher than the battery’s rated voltage of 24V. Also, factor in the duration of charge when deciding



whether to trust the battery charger’s automatic cutoff. Battery packs which are completely dis-charged should require 3-4 hours to reach a full charge. If you suspect that the charging cycle may have terminated prematurely, disconnect the battery charger from its AC supply, wait for the LED to turn off completely, then reconnect the battery charger and restart the charge process.

Figure 11. Charging the Batteries

Battery Charging Recommendations Battery Use:

• Inspect the battery packs for damage regularly. Do not use damaged or distorted battery packs.

• Make sure the battery polarity is always connected correctly (Red to Red, Black to Black)

• Ensure that all battery connectors are secure and push/pull clips are tight.

• ALWAYS use THREE batteries in the Q/Z-1250. Do not operate on only two batteries. Doing so can cause premature failure and/or damage to the batteries.

• Never allow water to get inside of the battery pack or Power Module. If there is any evidence of corro-sion, do not use the battery pack.

• There is no need to remove the battery from the Power Module housing to charge the battery.

• Battery packs will self-discharge when not in use. For best endurance, recharge all battery packs be-fore use if more than a few days have passed since they were last charged.

Battery Charging:

• Always charge in a ventilated area on a work bench away from flammable materials. Do not charge the batteries inside of the boat.

• Do not leave batteries on charge overnight. Charge when they can be monitored periodically.

• Do not overcharge batteries. Limit charge times to a maximum of 10 hours.



• If the resting 24V battery pack voltage measures less than 16V, do not charge it. The battery pack is no longer usable and should be disposed of properly.

• Under rare circumstances, the charger may finish the charging cycle prematurely before the battery has been fully charged. Verify that the battery has been fully charged by measuring the voltages across each of the 3 discharge terminals. All voltages should be roughly equal and should be higher than the battery’s rated voltage of 24V. Also, factor in the duration of charge when deciding whether to trust the battery charger’s automatic cutoff. Battery packs which are completely discharged should require 3-4 hours to reach a full charge. If you suspect that the charging cycle may have terminated prema-turely, disconnect the battery charger from its AC supply, wait for the LED to turn off completely, then reconnect the battery charger and restart the charge process.

• Once each month, the propulsion battery(s) should be fully discharged before recharging to avoid memory problems that may be caused by repeatedly charging partially discharged batteries.

Battery Charging Sequence:

• Connect the Anderson power leads between battery pack and charger.

• Plug the charger into an AC power supply. The red LED will blink on/off a couple of times then stay on showing that it is charging.

• After battery is fully charged the green LED will be on showing that the battery is fully charged. The battery should now be disconnected.

• The LED will stay green if there is no battery connected; the charger is functioning properly.



Installing the Battery System To install the batteries:

1. Remove the battery compartment cover. Note there is a lanyard attached to the battery cover and the O-Ring on the battery cover. Do NOT place the cover where it is in contact with dirt.

2. Load the three NiMH battery packs in the Q/Z-1250 hull with the leads facing toward the elec-tronics box.

3. Connect all three power leads to the electronics box as shown. Insure polarity is correct (red to red, black to black).

4. Inspect the battery cover O-Ring. Verify it is clean and no dirt is present. Clean the O-Ring mating surface on the battery compartment with a lint free wipe.

5. Install the battery compartment cover and evenly tighten all six screws. Make sure the lanyard and battery leads are not pinched by the cover when installed.

Figure 12. Installing the Batteries



Charging the Transmitter Battery The Hitec Aurora 9 remote control transmitter is powered by a 6 cell 7.2V NiMH battery with a 110-220V charger. The charger is simply plugged into the rear of the transmitter, marked Charge as shown below. The charger should not be connected to the battery continuously for more than 24 hours. The charging procedure is complete in 12 hours and the charger should be disconnected once the battery is fully charged.

Be careful not to plug the battery into the transmitter with reverse polarity. The connector is keyed to prevent this, but if forced onto the unit, it will be destroyed!

DO NOT turn the transmitter power on or attempt to use the transmitter while charging. Serious damage may occur rendering the unit inoperable.

The LCD display shows the battery charge in volts or percentage of full charge. The screen may be pressed to toggle between the two choices (see below 100% or 8.0V).

1. Tap on %

2. Display changes to volts



Charging the Power/Telemetry Module The optional Power/Telemetry module is powered by an internal 14V, 4.5Ah NiMH battery.

To charge the system:

6. Disconnect all instrumentation from the module and remove the module from the boat.

7. Place the module in a well-ventilated area away from flammable hazards. There is no need to re-move the battery from the module.

8. Connect the provided smart charger and charging cables (73L-4004-00 and 73L-4005-00) to the Charge port on the module.

9. Plug the smart charger into an acceptable wall unit; the charger’s LED will flash red a couple of times then shift to solid red. NOTE: if the charger is plugged into a wall outlet prior to connecting the battery, it may not switch into a charging state automatically and the LED may remain green. If that occurs, unplug the charger from the wall until the green LED fades off, then plug it back into the wall.

10. When charging is complete the LED will change to illuminate green.

11. Do NOT overcharge the module. As with any battery, the module should be supervised while charging and should not be left unattended. Ensure the module is disconnected as soon as charg-ing is complete.

Figure 14. Charging the Power/Telemetry Module



Antenna Safety Antenna problems are the most likely cause of Q/Z-1250 control issues or poor data transmission range. It is critical to ALWAYS check the antenna bulkhead connections before deployment. Ensure the antenna pins are properly interfaced with the bulkhead connector and check that the antenna cables are connected and tightly fastened. It is not good enough that the antenna is screwed in – the center pin needs to make a good connection between the antenna and the cable / bulkhead. ALWAYS make sure the external anten-nae are tightly installed –they could vibrate loose while the boat is in action.

Check all antenna connections before deployment.

Range Testing Before each deployment, it is good practice to conduct a range test, where the boat is kept stationary and the operator moves away to check that good control of the boat navigation is maintained as the distance increases. Select a control position so the user can move closer to the boat in an emergency. For example, do not set up at the shoreline where the operator cannot move closer to the boat if a control issue arises. Setting up the RC controller 50 feet back from the bank affords the operator 50 feet of “reserve” range.

Always conduct a range test before deployment.

Antenna Position The two antennae aft of the battery compartment are for the remote control system. The black stub anten-nae should be positioned at a 90-degree angle to maximize signal strength. Both antennae should NOT be pointed vertically upwards. The worst orientation is both antennae flat and horizontal; this should ALWAYS be avoided. Teledyne Oceanscience recommends the following antenna orientation:

Figure 15. Antenna Position

Position one antenna UP and one antenna rotated 90 DEGREES outboard to maximize the signal strength with the RC transmitter antenna (see Figure 16).

If using the optional Power/Telemetry module, its antenna should be oriented vertically.



Elevation The data telemetry and remote-control range achieved will be GREATLY increased as the operator posi-tion is elevated. Elevation is the single biggest factor in achieving effective range. It is advisable to select a control position where there is maximum elevation, even if this means the operator will be further from the boat. Both the RC and data antennae are close to the water surface and an elevated control position greatly enhances the ability of the boat to send / receive data.

Elevation is critical in determining operating range.

The orientation of the RC transmitter antenna becomes important during long range operation. The transmitter antenna must not be pointed at the boat but instead should remain vertical – in the same di-rection (plane) as the boat antennae receiving the signal.

Figure 16. Omni Antenna

The antenna is Omni directional (the best reception is around the antenna in a doughnut shape); do not orientate the antenna by pointing the tip of the antenna at the boat.



Powering Up the Boat and Transmitter The transmitter should be fully charged before each survey and will operate for several hours when charged up to 100% indicated on the LCD screen. The transmitter will shut down when the LCD display indicates 0% battery life remaining. Please see Charging the Remote Transmitter for further details.

Always turn the transmitter power on first and then turn the Q/Z-1250 power on second. Do not turn the Q/Z-1250 boat power on before the transmitter.

Q/Z-1250When the Q/Z-1250 is turned on, it looks for a RC signal, and if the transmitter is on then it im-mediately locks to the transmitter signal. The transmitter will beep three times and the propulsion battery voltage will be shown on the LCD display. If the transmitter is not on when power is applied, the boat may be affected by stray radio signals. This is dangerous as it can potentially damage the motors on the boat or create an unsafe operating condition such as motors operating unexpectedly.

Make sure the throttle is at zero before turning on the transmitter. The transmitter will issue an alarm if the boat is turned on with the throttles open. This promotes safe operation.

The transmitter will beep three times when the boat is powered up and the boat voltage display will appear on the LCD panel. If this does not happen, there is no radio link established. Do not launch the boat! Always perform checks that the transmitter is properly controlling the throttles and steering before launching the boat.

The optional Power/Telemetry Module has its own power switch. Once the Q/Z-1250 power is on, press the power switch on the Power/Telemetry Module to apply power to the connected Instrument and/or GPS.

Battery Voltage Monitoring

Failsafe Mode Selection

Using the Remote Control

Using the Optional Power/Telemetry Module



Battery Voltage Monitoring The Hitec transmitter continuously monitors the Q/Z-1250 battery voltage; an alarm will sound when the voltage becomes too low signaling that the boat should be brought back to shore. If the voltage falls below a threshold value as shown below, control of the boat will no longer be possible.

Starting Voltage 26 – 27V

Default alarm set point 22V

Completely dead batteries 18V The battery alarm voltage setting can be changed by the user if required (see Setting the Low Voltage Alarm). The alarm set point can be lowered if it is safe to do so. Note that the voltage will drop as soon as the throttle is opened and power is applied to the motors; this is normal. As the current to the motors in-creases with speed, the voltage goes down slightly; this may trigger the alarm. The top speed of the boat will also decrease as the battery voltage decreases.

If the low voltage alarm sounds prematurely you must recover the Q/Z-1250 immediately as one or more of the battery packs or cells may not be properly connected.

Battery voltage at rest Battery voltage with motors at full power

Figure 17. Monitoring the Q/Z-1250 Battery Voltage

Failsafe Mode Selection Should the remote control signal be lost, the boat is pre-programmed to enter an emergency “failsafe” mode. This might happen under the following circumstances:

• The transmitter batteries fail.

• The boat goes behind a structure or large boat and is out of radio contact.

• The boat is too far away and goes out of control range.

• The transmitter is turned off.

Always check the transmitter battery power before starting work.



Always check the failsafe by turning the transmitter “off” after powering up the Q/Z-1250 to make sure the failsafe works as expected.

Always perform a range test. With the boat on land, walk away from the boat and ensure that the con-trols still work at a distance further than you plan to control the boat on water.

The factory failsafe settings are as follows:

Port Motor: 0% Throttle

Starboard Motor: 0% Throttle

This failsafe setting protects the operator if the controller is shut off prior to the boat power, and will cause the boat to drift downstream with the current in river discharge measurement applications. Tele-dyne recommends an operating position that is downstream of the measurement location whenever possi-ble. In special circumstances, other failsafe settings may be more suitable and we recommend contacting Teledyne Oceanscience for help changing the failsafe setting if this is desired.

Using the RC Transmitter End Point Adjustment (EPA)

The Q/Z-1250 transmitter may be programmed via the LCD panel to alter the boat performance charac-teristics in several useful ways, including:

• Adjusting the speed at maximum throttle to give easier control of survey speed.

• The boat can be made to go more slowly when the throttle is held in the full forward position if the speed is adjusted downwards from the factory default of 75% (maximum effective setting).

• See Setting Throttle End Points (Restricting Boat Speed).

EPA Performance Notes

• The maximum speed of the Q/Z-1250 is approximately 2.3 m/sec with fully charged batteries, meas-ured relative to the water (NOT the bottom). Speed over ground will depend on water velocity as well as throttle setting in river applications.

• Endurance of the Q/Z-1250 will decrease significantly with increasing throttle position and speed over water.

• At maximum throttle, steering input will decrease the boat speed since one motor must be retarded in order to turn.

• Speed at maximum throttle will reduce as the battery discharges due to the decrease in effective bat-tery voltage.

Steering and Throttle Models

The Q/Z-1250 may be operated with several different transmitter stick setups, allowing people who are left or right handed to be equally comfortable. The Q/Z-1250 has no rudder, thus it always uses differen-tial thrust steering. Q/Z-1250See Throttle and Steering Control Models for further information.

Control Stick Characteristics

The throttle and steering sticks can be operated with either a spring loaded self-centering action or a ratchet (not self-centering). Adjusting the throttle ratchet may be useful: changing the throttle to ratchet operation will keep the boat at the same speed without the operator having to touch the throttle stick. See Changing the Control Stick Characteristics for further information.



Selecting Throttle and Steering Control Models The transmitter has three different control models used to operate the Q/Z-1250, as follows:

Table 1. Throttle and Steering Control Models Mode Left Stick Right Stick

MODEL 1 Throttle (both motors) Steering

MODEL 2 Steering Throttle (both motors)

MODLE 3 Port motor throttle Starboard motor throttle It is up to the user to determine which of the control models is most suitable. Model 1 or 2 is preferable for beginners to gain experience handling the boat and is most often used. For experienced users, model 3 may be preferred, and is useful in low velocity conditions. Throttle control for all models uses for-ward/backward stick motion, and steering control for models 1 & 2 uses left/right stick motion. Steering control for model 3 is obtained by differential throttle positions on the left and right sticks.

The model is selected by pressing on the LCD display. The factory setting is model 1. To change this to any of the other models, follow the instructions below:

Tap the control model that is currently set.

Tap the new control model from the list.

Tap Select.

Tap Yes to switch models.



The selected model displays on main screen.

Setting Throttle End Points (Restricting Boat Speed) The maximum throttle power can be adjusted on the transmitter to reduce the Q/Z-1250 top speed with the stick(s) in the fully forward position. This allows for a fine control of boat speed and easier control of the boat in slow or still water.

It is recommended that the throttle response is adjusted using the End Point Adjustment (EPA) before commencing a survey. If the Q/Z-1250 is operated at maximum speed, battery life is adversely affected and the total survey line distance that can be covered on each battery charge may be significantly less than at a lower speed that will be more "fuel efficient".

Endurance is reduced significantly when operated at high speed.

Q/Z-1250For river discharge measurement applications the peak water velocity in the river and the river width will determine the minimum safe top boat speed. The EPA setting should always provide a top speed at least 20 to 30% higher than the river’s peak water velocity to avoid control issues and ensure that the boat is not washed downstream by the flow in the river, since the top boat speed will be reduced when the operator is applying steering input. An EPA setting of 75% ensures that the boat’s maximum speed ca-pability is always available. An EPA setting of 55% will provide a top speed of approximately 1.5 m/sec, while an EPA setting of 40% will provide a top speed of approximately 1.0 m/sec. EPA setting below 40% are not recommended.

IMPORTANT: The EPA is set for each individual control model. For example, if model 1 opera-tion (right stick steering, left stick throttle) is selected, the end points shown on the LCD panel only ap-ply to model 1. To change the end points for the other control models, select each model in turn and then follow the end point adjustment procedure for each mode.

How to set END POINTS:

Select the system menu signified by the wrench image.

Select the EPA Menu.



The EPA menu shows the two motors’ throttle settings for that control mode (see picture below).

• + is forward direction

• - is reverse direction

• The Q/Z-1250 utilizes the channels 2 and 3 settings.

• Channels 2 and 3 are the starboard and port throttles, respectively.

• The maximum available setting is always 140% but the maximum useful setting is 75%; this will give maximum boat speed in water. Higher settings will simply reduce the effective stick control range.

• Do not set the reverse direction above 75%.

• The port and starboard throttle channels should always have the same EPA settings, otherwise the boat will have a strong tendency to turn in circles due to unbalanced thrust from the two motors.

• The lower the percent setting, the slower the boat will go.

• Test the settings thoroughly before deploying the boat.

Adjust the EPA settings by pressing on the channel to be adjusted. The forwards and backwards (+ and -) directions are selected by moving the throttle stick(s) forward and back.

The percent setting is increased or decreased by pressing on the “+” or “-“ arrows at the bottom of the LCD display.

To make the boat slower, press “-“,

To make the boat faster, press “+”.

Pressing RST resets the throttles to 100%.

To EXIT from any menu on the display, press the BACK key.

Follow the pictures and examples below on how to select the Right/Left motor channels:

Forward direction (+)

Reverse direction (-)

Starboard Throttle – Channel 2 Port Throttles – Channel 3



Select right motor channel.

Right motor channel is highlighted.

Right (Starboard) motor throttle = Channel 2

Press stick back for reverse direction.

Release the stick.

Select the left motor channel.

Left motor highlighted

Left (Port) motor throttle = Channel 3



EXAMPLE: Reduce maximum throttle on right motor from 75% to 50%:

Select right motor channel.

Right motor is highlighted.

Right (Starboard) motor throttle = Channel 2

Press stick forward for forward direction.

While holding the stick forward, tap the minus arrow to reduce the maximum speed to 50%.

The settings can be changed back to the factory 75% / 75% by this procedure, using the “+” arrow button to increase the maximum speed.



Changing the Control Stick Characteristics The Q/Z-1250 transmitter is set up from the factory with “self-centering” throttle controls. When the throttle stick is released, a spring causes it to go back to the zero center position immediately. This helps to provide safe operation of the boat, especially for inexperienced users.

The springs that cause the “self-centering” can be deactivated, and then a ratchet activated on the throttle sticks to allow the sticks to remain at the set throttle position even without being held there by the opera-tor. This is sometimes preferred when using the Q/Z-1250 in “dual throttle” mode (Mode 3). It is also very useful when conducting long surveys as the throttle stick can be left in position to maintain a constant speed.

To change the spring and ratchet settings, four small screws can be accessed through the rear of the trans-mitter, as shown below. The following adjustments are possible:

• M1/3 – Right throttle spring off (clockwise), spring on (anti-clockwise).

• M2/4 – Left throttle spring off (clockwise), spring on (anti-clockwise)

A – Right throttle ratchet off (anti-clockwise), ratchet on (clockwise). Two screws are under the protective cover - use screw on right.

B - Left throttle ratchet off (anti-clockwise), ratchet on (clockwise). Two screws are under the protective cover – use screw on left.

Screw A / B positions with protective covers removed:

1. The spring for the left (port) motor throttle can be turned off by turning the M2/4 screw anti-clockwise.

M1/3

M2/4 A

B

A

2. The ratchet for the left (port) throttle can be activated by turning screw B clockwise until the ratchet sound is heard when moving the stick.

3. The spring for the right (starboard) motor throttle can be turned off by turning the M1/3 screw anti-clockwise.

4. The ratchet for the right (starboard) throttle can be activated by turning screw A clockwise until the ratchet sound is heard when moving the stick.



Do not loosen any screw more than four or five turns as it may come loose. The spring activation / deactivation requires only one turn.

Setting the Low Voltage Alarm IMPORTANT: The voltage alarm is set for each individual control mode. For example, if mode 1 operation (left stick throttle, right stick steering) is selected, the battery low voltage alarm shown on the LCD panel only applies to mode 1. To change the low voltage alarm for the other control modes, select each mode in turn and then follow the battery voltage alarm setting procedure for each mode.

If any of the control modes have the low voltage alarm “off”, then switching to this control mode will disable the alarm.

To set the Low Voltage Alarm:

On the main menu, tap the Wrench icon

( ).

Tap System tab Sensor Battery.

At Warning(Low), press the plus sign (+) or minus sign (–) until the value reads:

22.0v for Q/Z-1250.

Tap the Back icon several times until you reach the main menu.

Repeat setting the low voltage alarm for all models.

Return to the desired Model after the low voltage alarm setting is applied to all models.



Using the Power/Telemetry Module The Q/Z-1250 may be configured with an optional Power/Telemetry module to enable use of externally powered sensors and sensors that require external radio data transmission.

Overview The Power/Telemetry module is a self-contained unit with battery and Bluetooth radio inside. A shore Bluetooth radio is required for telemetry and may be provided with the system depending on the configu-ration. The module has two data ports, a battery charging port, an antenna connector, and a power but-ton. See Instrument Installation for details on configuration-specific connections.

Figure 18. Power/Telemetry Module Overview

Setup The Power/Telemetry module should be fully charged before use. See Charging the Power/Telemetry Module. The Q/Z-1250 Power/Telemetry module is recommended to be used with the SD1000U USB Bluetooth adapter. Other Bluetooth radios may be used with the module if desired.

All instruments connected to the Power/Telemetry Module (RiverRay, RiverPro, Single Beam Echo Sounder, or GPS) should be configured to output data with Baud rate 115,200.

With all instrument connections made (see Instrument Installation), depress the power button to turn on the module. The power button will glow blue when the module is powered on. The module will now pro-vide power to connected instrumentation and its internal Bluetooth radio will be active. If the module has already been paired to a SD1000U which is also powered on, their connection will re-establish automati-cally. If a new SD1000U or one with Mode set to 0 is used, it can be connected to the Q/Z-1250 Power/Telemetry module now.



Operation Always test the data telemetry function before beginning a survey.

With all instrument connections made (see Instrument Installation), depress the power button to turn on the module. The power button will glow blue when the module is powered on. The module will now pro-vide power to connected instrumentation and its internal Bluetooth radio will be active.

Connect the paired SD1000U to the laptop. It should automatically connect to the Power/Telemetry module and the SD1000U “Connect” LED will blink to indicate the successful connection. The SD1000U “RS232” LED should blink to indicate receipt of data.

The SD1000U com port can now be opened in a terminal program or other software to receive the data from the Power/Telemetry module at Baud rate 115,200. See SD1000U Com Port Identification.

Using the SD1000U USB Bluetooth Adapter

The SD1000U USB Bluetooth device is recommended for use with the Q/Z-1250 Power/Telemetry mod-ule and is included with some systems depending on configuration. The SD1000U appears as a com port to a laptop.

If your SD1000U device was not included as a configured part of a Q/Z-1250 system, see Pairing the SD1000U for configuration steps.

• This information was created using the SD1000U on a Windows 7® laptop.

• For compatibility with the Q/Z-1250 Power/Telemetry module, set all baud rates to 115200Kb.

In Windows XP® and later systems the driver may load automatically when you plug in the SD1000U adapter. TRDI strongly recommends that users install the drivers and test communications in a location with internet access, before proceeding to their measurement location.

SD1000U Baud Rate Setting Refer to the Sena documentation and the diagram on the device for switch settings or use the table below. The switches are shown with the adapter held in your hand with the USB connector to the left and the an-tenna to the right. For the DIP switches, ON = Right; OFF = Left. The switches on the dongle determine the baud rate between the dongle and the laptop. All devices connected to the Q/Z-1250 Power/Telemetry module including the SD1000U should have a Baud rate setting of 115200.

TRDI has observed latency issues while collecting data using a Bluetooth adapter other than the SD1000U. The user must take suitable precautions. All devices connected to the Q/Z-1250 Power/Telemetry module including the SD1000U should have a Baud rate setting of 115200.

After Each Use Maintenance

Checking the Thruster Oil Compensation

O-Ring Replacement



General Maintenance

After Each Use The Q/Z-1250 is designed to be easy to maintain.

• To prolong the life of the hull and finish, wash with mild soap and water after each use. Use a hose with a low velocity spray nozzle to rinse the top and bottom. The system can be stood on its end to fa-cilitate rinsing the underside.

• If operating in saltwater, rinse the hull and motors with fresh water after each use. Place the system in a container of fresh water and run the thrusters for a period of about two minutes at low speed to rinse any salt, mud or other contaminants from the exterior of the system. Utilization of this method ensures the best clean possible.

• When possible, allow the system to air dry prior to stowing in the transit case. Low pressure air and clean dry towels can be substituted to speed the drying process.

• Check the battery compartment cover O-Ring for cuts, cracks or deformation. This O-Ring seals the battery area from water intrusion and should be checked frequently.

After Each Use (Dirty Water Conditions) When the system is operated in dirty water environments with high sediment loads or significant biologi-cal activity or the presence of drifting debris, the cleaning process will need to be more involved.

First visually inspect the propeller guards for fouling. Any material sticking out from under the propeller requires the removal of the propeller to remove the fouling. With material under the hub of the propeller, the potential for the material to be ingested into the shaft seals of the propeller is increased.

To remove the propeller:

1. Disconnect and remove the batteries from the boat.

2. Remove the two each 6 mm radio pattern nuts, and pull the propeller off of the collet.

3. Remove any debris from underneath the propeller hub and re-install.



Checking the Thruster Oil Compensation After every 50 hours of operational use, we recommend checking the fill level on the oil compensation bladders for each thruster. This procedure should also be performed if the system has been stored for six months or more.

To check the oil compensation bladder:

1. Place the boat bottom side up on a flat stable surface.

2. Locate the oil compensation bladder on each thruster, visually verify that the bladder is filled and not flat or distended. Check for small to medium sized air bubbles in the oil compensation tube.

3. If required, add oil from the Oil Compensation Top Off Kit following the instructions provided with the kit.

4. Connect and test the thrusters.

Filling the Oil Compensation Tube To fill the oil compensation tube:

Kit Includes:

• LU003 – 250 ml – KLEAROL® mineral oil

• SS081 – 1 ea - 10cc syringe

• SS176 – 1 ea - Needle-taper 22Ga

• DOCS-025 Manufacturer Safety Data Sheets (MSDS), Mineral Oil - 1443952

Tools required, but not provided in the Oil Compensation Top Off Kit:

• #2 Phillips screwdriver

• Diagonal cutters

Optional:

• Paper towels

• Isopropyl alcohol, (for oil spill cleanup)

Read the entire procedure prior to performing any work outlined in this manual. If any questions remain, please contact Seabotix service department at 619-450-4000 Ext 124 or e-mail [email protected] or contact your local distributor. A complete listing of Teledyne SeaBotix Inc. distributors can be found on our web site www.seabotix.com.

Read and follow all safety instructions contained in the Manufacturers Safety Data Sheet (MSDS) (DOCS-025) provided with your Oil Compensation Top Off Kit. It contains important information regarding the safe handling of the oil provided.

Teledyne recommends that latex or rubber gloves be worn during the oil handling portions of this procedure.


http://www.seabotix.com/



Set up a clean work area. Cover the work surface with a paper towel to absorb any spilled oil.

Stand the thruster up in a Kort nozzle.

Remove the oil compensation tube from the two clips holding the tube in place.

Remove the seal screw from the oil com-pensation bladder. Once the screw has been removed, you will have to keep the oil compensation bladder open end pointed up. Securing it to a vertical sur-face will ease accomplishment of this task.

Fill the supplied syringe (SS081 with SS176 needle taper tip Installed) with approximately 5cc of mineral oil (LU003). Then insert the oil filled sy-ringe into the end of the bladder.

Inject the oil into the oil compensation bladder until the oil is even with the top of the radius of the compensation blad-der.

It may be necessary to slightly twist the bladder to remove any set taken by the oil compensation bladder.

Install the seal screw; only inserting 2-3 threads into the plastic end.

Fill Oil to this level



While holding the top of the oil compen-sation tube, tap the lower section with your fingers. The goal here is NO AIR. Continue tapping until all the air bub-bles have risen to the top of the oil com-pensation bladder.

Add more oil if needed to fill the com-pensation bladder all the way up to the radius of the oil compensation bladder section.

Gently squeeze the oil compensation bladder to remove all of the air.

At first there will be small bubbles that will form around the base of the screw; then the oil will start to come out.

Once no more bubbles are coming out with the oil, tighten the seal screw.

Do not over tighten the seal screw, as it may damage the threads or the O-ring.

Press the oil compensation bladder into the two clips as shown.



Replacing the O-Ring The battery compartment O-ring should be cleaned whenever the cover is removed and replaced BEFORE it is showing any signs of wear and tear.

The O-ring should be replaced every one to two years maximum.

To replace the O-ring:

1. Turn the power switch off.

2. Open the battery compartment by removing all six screws. Note there is a lanyard attached to the battery cover.

3. Gently pry the O-ring from the groove. Use a wood or plastic wedge to help lift the O-ring from the groove.

4. Clean the O-ring groove using a lint free cloth. Be sure the groove is free of foreign matter, dirt, and scratches.

5. Lubricate the O-ring with a thin coat of silicone lubricant. Use as little lubricant as possible; use just a sufficient amount to change the color of the O-ring.

Apply the lubricant using latex gloves. Do not let loose fibers or lint stick to the O-ring.

Fibers can provide a leakage path.

6. Press the O-ring into the groove on the battery cover.

7. Clean the O-Ring mating surface on the battery compartment with a lint free wipe.

8. Install the battery compartment cover by installing all six screws until fully tightened. Make sure the lanyard and battery leads are not pinched by the cover when installed.

Figure 20. Replacing the Battery Compartment O-Ring



Replacing a Thruster To replace a thruster:

1. Turn off the power switch and disconnect the batteries.

2. Disconnect the thruster cable.

3. Remove the skeg by first removing the screw holding the skeg on the Kort nozzle. Then remove the two M4 screws, and flat washers. Slide the skeg away from the Kort nozzle to free it from the slot and set it aside (see Figure 21).

4. Remove the four M4 screws and flat washers on the thruster mounting plate. Thread the cable through the access holes and place the thruster.

5. When installing the new thruster, pass the cable through the hole before installing the four M4 screws and flat washers. Tighten the screws to 10.6 IN-LB.

6. Install the slot on the skeg onto the Kort nozzle and install the screw. Install the two M4 screws and flat washers. Tighten the two M4 screws to 10.6 IN-LB.
