Liquid & Refrigerant Sensor Test Points
(Table 25)
Entering Chilled Liquid Sensor
J6-5 = +5VDC regulated supply to sensor.
J6-8 = VDC input signal to the I/O board. See
Table 25 for voltage readings that correspond
to specific liquid temperatures.
J6-2 = drain (shield connection = 0VDC) Return
Leaving Chilled Liquid Temperature Sensor
J6-4 = +5VDC regulated supply to sensor.
J6-7 = VDC input signal to the microboard. See
Table 25 for voltage readings that correspond
to specific liquid temperatures.
J6-1 = drain (shield connection = 0VDC) Return
