2. Installaon and Explanaon
Installaon and Explanaon
- The controller Should be mounted Ver�cally in an acessible loca�on.
- Use Washers under the moun�ng screws to avoid damage and ensure a proper fixa�on.
- The controller is (if the provided caps are used) splashproof. (IP53)
- Venlaton is not necessary. opera�ng temperature between 0°C (32°F) and 60°C (140°F)
- Power supply 12v DC (min. 10volt max. 20 volt) DO NOT EXTEND THE POWER CORD. OBSERVE POLARITY RED = +12V BLACK
= NEGATIVE/ GROUND - Never use the thrusterbaeries to power the controller, instead use the servicebaeries
- All cables connected to the controller should: 1. Have adeqate tension relief mounted. 2. Not go together in a bundle with
220v/110v cabling. (min. 10 cm (4”) distance) 3. Not go together in a bundle with VHF antenna cables. (min. 10 cm(4”)
distance) 4. Be passed through Carefully to avoid damaging the cables

- The status led provides the same informaon as on the joysckpanel. (see next page Flashing codes)
- The Dipswitsches allow you to set up the controller for your applicaon. (see next page )
- The Invert switches allow you to invert the valve or thruster operaon.

*you can either use a latching switch or connect blue to brown ,to use the power supply on/off funcon.
(example: ign. switch) Never connect +12v to the control wires.
*you can either use a latching switch or connect blue to brown ,to use the power supply
on/off funcon.(example: ign. switch) Never connect +12v to the control wires.
In Case of electromechanical disturbance or stac discharge the controller will shut down.
Push the buon again to re-start the system.
Invert switches
Using these switches You can invert the valve- or thrusteroperaon, this simplifies installaon.
the le switch is for the stern and the right for the bow.
Warning: A wrong seng can cause damage or Injury!!
Keep your face and hands on a safe distance from thrusteropenings !!
Flashing Codes
- Green Led is o - No Power or defecve Fuse.
- Green Led is on - power present Controller is on and standby.
- Red Led is o - Controller is standby. ( automacally aer 10 minutes)
- Red Led is on - Controller is on and OK.
- Red Led Flashing fast - Engine overheated, (Let Cool Down, Auto reset)
- If system has never run, you need to create common ground (see page 12)
- Red Led Flashing code V - Valve not open or closed in me. (turn system o/on.
If malfuncon remains, one of the valves is stuck.
(Valve can be cleaned easely.)
If upon installaon the red led is ashing fast, make sure the Negave of ba�ery 1 (and pump) is connected to the ships
ground or the negave post of the baery powering the controller.

Please note: For a 12 Volts ship’s circuit you need to install a series-parallel switch to be able to charge the system on 12V
and use it on 24V. The JT-50, JT-70 and JT-90 come with a connecon wire F and G as a standard accessory
for this switch.
Recommended baery cabling: (at a total length of max. 1m/3)!
JT-30 (12V) 50 mm2 (1/0 AWG) for 1m/3
JT-50 (24V) 50 mm2 (1/0 AWG) for 1m/3
JT-70 (24V) 70 mm2 (2/0 AWG) for 1m/3
JT-90 (24V) 95 mm2 (3/0 AWG) for 1m/3
Posive cable total length max. 50cm./1.64 
Negave cable total length max. 50cm./1.64 
For opmum performance keep
baery cables as short as possible!!
Charging the baeries:
In order to keep the ship’s circuit separate from the Jet Thruster baery/baeries it is recommended to divide the charging
current with a diode bridge or MosFet baery separator from the alternator.
Please note: More electricity will be required as a result of the installaon of the Jet Thruster. That is why in some cases it is
recommended for the alternator to be converted to high yield or to place a separate alternator.
Please note: Place baeries directly next to the pump unit.
Keep baery cables as short as possible to avoid voltage drop and loss of energy.
The electric motor of the Jet Thruster generates a lot of power in a short period of me. It is necessary to
connect dedicated baeries to the system. It is necessary to make the connecon between this baery and the
system as short as possible. Use appropriate baery cables and connecng material for this at all mes.
The system must be equipped with the included main fuse, which must be installed in the baery posive cable.
For safety reasons, the Jet Thruster should be provided with a suitable main switch (not included).
The joysck operates on 12V. For vessels with a 24V installaon, a DC-DC converter must be applied.
To avoid long cable length:
Baeries must be placed directly next to pump unit!
