When any of the following is detected:
- Relay contact is off (BS2 terminal is less than 3.5 V) for at least 0.2 sec. when R2+ terminal voltage is 9.0 V or more and main relay 2 is on.
- R2+ terminal voltage is less than 9.0 V and main relay 2 cannot be on for at least 2 seconds when main relay 2 is turned on (BS1 terminal is 3.5 V or more).
- With the main relays 1 and 2 ON and all solenoids and the motor relay 1 and 2 not activated, the BS2 terminal voltage is lower than BS1's by 2 V or more for 1 second or more.
- With the solenoid OFF, the difference between BS1 and BS2 is 2 V or more for 2 seconds or more.
