TWINDOSE 35 – System for dishwashers
2.4.2 Fixed power supplies and dishwashers with 1 solenoid valve (ENCLOSURE B)
• Check the voltage on the main power supply and make sure that it is the same as that shown on the
TWINDOSE 35’s data plate.
• Disconnect the dishwasher from the electrical power supply.
• Check the voltage on the dishwasher’s rinse solenoid valve and insert Jumper JP2 in the HIGH (150 – 265 Vac)
or LOW (20 – 265 Vac) position, depending on whether you are using a 220 Vac or 24 Vac solenoid valve.
• Connect the main power supply cables to terminals 3 and 4 (AC MAINS RINSE)
• Connect the rinse signal wires to terminals 7 and 8 (RINSE SIGNAL) on the circuit board.
• If you want to use the system with the conductometric sensor, connect the wires for the washing pump
contactor coil to terminals 9 and 10 (WASH SIGNAL) on the circuit board.
When doing this, check the voltage on the dishwasher’s washing pump contactor coil and insert Jumper JP3 in
the HIGH (150 – 265 Vac) or LOW (20 – 265 Vac) position, depending on whether it is a 220 Vac or 24 Vac coil.
• When using the rinse aid pump in timer mode for single tank dishwashers, it is advisable to connect terminals 7
and 8 electrically to the dishwashers’ washing pump contactor coil. In this case rinse aid will be dosed to the
boiler during the washing stage for use in the next rinse cycle.
TWINDOSE 35 is fitted with a switching feeder that allows it to be powered using voltages of between
80 and 265 Vac.
When connecting up the conductometric sensor, refer to paragraph 2.6 and enclosure B, at the end of
this manual.
2.4.3 Power Supply from the Load and Rinse signals (ENCLOSURE C)
• Check the voltage on the charge and rinse solenoid valves and make sure that it is the same as that shown on
the TWINDOSE 35’s data plate.
• Disconnect the dishwasher from the electrical power supply.
• Check the voltage on the charge and rinse solenoid valves on the dishwasher and insert the relevant jumpers
JP1 and JP2 in the HIGH (150 – 265 Vac) or LOW (20 – 265 Vac) positions, depending on whether you are
using 220 Vac or 24 Vac solenoid valves.
• Connect the rinse solenoid valve to terminal 3-4 (AC MAINS RINSE) on the circuit board.
• Connect the charge solenoid valve where fitted to terminal 1-2 (AC MAINS DETERGENT) on the circuit board.
• Form a bridge between terminals 3-4 and terminals 7-8.
• Form a bridge between terminals 1-2 and terminals 5-6.
• If you want to use the system with the conductometric sensor, connect the wires for the dishwasher’s washing
pump contactor coil to terminals 9 and 10 (WASH SIGNAL) on the circuit board.
When doing this, check the voltage on the dishwasher’s washing pump contactor coil and insert Jumper JP3 in
the HIGH (150 – 265 Vac) or LOW (20 – 265 Vac) position, depending on whether it is a 220 Vac or 24 Vac coil.
