(b) Apply negative (-) auxiliary battery voltage to the connector terminals 1 (GND) and 7 (DOWN)/10 (UP).
(c) Check that the motor gear rotates smoothly as follows.
OK:
| Measurement Condition | Specified Condition |
|---|---|
| Auxiliary battery positive (+) → 2 (B) Auxiliary battery negative (-): 1 (GND) (3 seconds or more) → 1 (GND) and 10 (UP) (within 1 second) → 1 (GND) (within 1 second) → 1 (GND) and 10 (UP) | Motor gear rotates clockwise (UP) |
| Auxiliary battery positive (+) → 2 (B) Auxiliary battery negative (-): 1 (GND) (3 seconds or more) → 1 (GND) and 7 (DOWN) (within 1 second) → 1 (GND) (within 1 second) → 1 (GND) and 7 (DOWN) | Motor gear rotates counterclockwise (DOWN) |
