INPUT MODIFICATIONS DEFINED
PRESSURE SWITCH INPUT
The pressure switch is a two level pressure switch. (Figure
During wash fill, the low level of the pressure switch is sensed with 24 VDC and provides an indication to the control board the water level has satisfied the low level. Once satisfied, the 24 VDC circuit is opened. The board then opens the water valve relays and shuts off the water valves.
During rinse fill, the high level provides an indication to the machine control as to whether the high water level has been reached. When the water level switch is satisfied, the pressure switch circuit is opened and power for the water valves is no longer passed through the machine control.
