Liquid and Refrigerant Sensor Test Points

(Table 35)
Entering Chilled Liquid Sensor
J6-5 = +5VDC regulated supply to sensor.
J6-8 = VDC input signal to the I/O board. See Table 35
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
35 for voltage readings that correspond to spe-
cific liquid temperatures.
J6-1 =drain (shield connection = 0VDC) Return.
