Flux Sensors -
If trigger connection points cannot be established, the magnetic field readers (82.23.1) may be used in
place of the trigger board and cable. The magnetic field readers or flux sensors connect directly to the control board in
the trigger wires spots as shown on the wiring diagram. The magnetic field readers or flux sensors can be placed on
wash motors or rinse valves to measure a magnetic field when the motors or valves are activated which will trigger the
proper pump or valve on the dispenser.
1.
Connect the wash trigger (white and brown wires) to the appropriate wash trigger output (between 24 and 480
V 50/60Hz) as recommended by the dish machine manufacturer.
2.
Connect the rinse trigger (black and red wires) to the appropriate rinse trigger output (between 24 and 480 V
50/60 Hz) as recommended by the dish machine manufacturer.
3.
Make sure to connect the earth ground (green wire) to the ground connection on the dish machine as
recommended by the dish machine manufacturer.
Main Power should be applied any time there is power to the dish machine. The main power cable will come out of the
conduit fitting with the trigger cable and be hooked up near the same electrical connection point on the dish machine.
If there is ever any question about the main power or trigger cable connection to the dish machine, please check
with the dish machine manufacturer to see where the proper trigger connection points are located before
installing the trigger connection wires.
