Liquid and Refrigerant Sensor Test Points

(Table 22 on page 160)
Entering Chilled Liquid Sensor
J6-5 = +5VDC regulated supply to sensor.
J6-8 = VDC input signal to the I/O board. See Table
22 on page 160 for voltage readings that cor-
respond 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
22 on page 160 for voltage readings that cor-
respond to specific liquid temperatures.
J6-1 = drain (shield connection = 0VDC) Return
