Solar Sensor: Testing and Inspection

HEATING / AIR CONDITIONING: SOLAR SENSOR: INSPECTION

INSPECTION





1. INSPECT SOLAR SENSOR (AUTOMATIC LIGHT CONTROL SENSOR)
(a) Remove the solar sensor with the connector still connected.
(b) Apply battery voltage between terminals 6 (CLTB) and 3 (CLTE) of the A/C solar sensor.
(c) Measure the voltage according to the value(s) in the table below.

Standard Voltage:





If the result is not as specified, replace the solar sensor.

HINT:
- As the inspection light is moved away from the sensor, the voltage increases.
- Use an incandescent lamp for inspection. Bring it within 30 cm (11.8 in.) of the solar sensor.
