Entering Chilled Liquid Sensor

J6-6 = +5VDC regulated supply to sensor.

J6-9 = VDC input signal to the microboard. See Table 48 for voltage readings that correspond to

specific liquid temperatures.

J6-3 = drain (shield connection = 0VDC)

Leaving Chilled Liquid Temp. Sensor

J6-5 = +5VDC regulated supply to sensor.

J6-8 = VDC input signal to the microboard. See Table 48 for voltage readings that correspond to

specific liquid temperatures.

J6-2 = drain (shield connection = 0VDC)
