Electric Heated Chassis & Frame
Hardware Group 60hz
The contol voltage is 115 volt ( 60hz) or 24 volt (50hz) to heat relay. Machine availlable in 208/240 volt 3
phase (60hz), 380/415 volt 3 phase (50hz) ONLY. Optional Temperature control board can be added for
non-heated machines to display temperatures and Steam option kit available . Steam valve will operate the
same as descibed throughout except valve will operate in place of heat relay.
Troubleshooting
If the heater relay does not engage in a heated bath:
Check the calibration switch is set to run position Check that I/O board jumpers are changed to the level
side, Jumper must start closest to level input light and open pin will be towards door input lights.
Check actual water temperature is less than programmed temperature
Check the temperature sensor for open circuit or shorted
Check low level contacts on the pressure switch not closing
Check low level safety relay contacts not closing or bad contacts
Check low level safety relay coil
Check heater relay contacts not closing or bad contacts
Check wiring between temperature board and sensor at all connectors and inspect wires for any damage.
If temperature control board is removed, the programmed temperature value is retained in all baths and
the water valves to fill that bath are chosen based on the programmed temperature as described on previ-
ous feature page.
Calibration
The calibration should be checked whenever a temperature sensor has been replaced or if actual water
temperature varies significantly from the display. To calibrate the temperature control board go to step # 15
of the diagonstic cycle(#31).Actual temperature will be shown in display. On the temperature control board
move the cal- run switch to the calibrate position. The factory set calibration
temperature of 98 degrees C should show on the display after a few seconds. Now turn the adjusting screw
clockwise to increase calibration point and display temperature or counterclockwise to decrease calibration
point and display temperature. The display is updated every 5 seconds so make adjustments in very small
increments. Be sure to allow ample time for display to respond to updates. If adjustments of higher than
100 degrees C only the last two digits will be displayed.
208-240 volt 3 phase (60hz) 308-415 volt 3 phase (50hz) power is supplied on L-1, L-2,L-3 to the normally
open contacts of the heat relay and then to the six heating elements. The elements are wired in star or wye
on 50HZ models. A delta configuration is used on 60HZ. models. There is a potential 220 volts across each
element for both models 60HZ or 50HZ. Control voltage 115 vac (60hz) or 24 vac (50hz) is used to power
the heat relay coil and will close the heat relay contacts. The supply voltage will intiate from the I/O board
Terminal number #6 (wht/blue wire) through the low-level safety relay contacts and then to the heat relay
operating coil when heat is being called for by temperature board. The neutral will be supplied from the
(blu/yel) wire connected to AC neutral terminal on the I/O board. The low level safety relay coil will operate
when the washer has filled to a level, and gets a signal from the pressure switch. That signal will be 24 VDC
and comes from the CPU board and through the pressure switch.
With the low level safety relay contacts now swtiched and closed , voltage now pass to the heat relay
operating coil, and allow main 3 phase voltage across the heating elements. Control voltage 115 vac (60hz)
is used to power the steam valve coil. The supply voltage will intiate from the I/O board Terminal number 6
(wht/blue wire) to the heat relay coil when heat is being called for by temperature board. The neutral will
be supplied from the (blu/yel) wire connected to AC neutral terminal on the I/O board. The valve gets a
signal from the pressure switch. That signal will be 24 VDC and comes from the CPU board and through the
pressure switch. With the low level safety relay contacts now swtiched and closed , voltage now will pass to
the heat relay operating coil, and allow main 3 phase voltage across the heating elements.
