Safety fence states do not match in the safety circuits. (for E0x series controllers)

Error handling: Motor power OFF.
Error reset: Possible.

Description: The safety fence contact states do not match between the 1st and second circuits.

Main causes:

1. Safety circuit wiring is incorrect, there is a wiring error, or only a single circuit is connected.

2. An open circuit or poor ground connection in the safety fence wiring.

3. The safety fence switch is faulty.

4. A problem with the power sequence board.

Countermeasures:

1. Check the safety fence circuit and wiring, and correct the wiring if necessary.

2. Replace the switch.

3. Replace the power sequence board.

Reference: On the teach pendant screen, select <Display 1> → → <Safety Circuit Monitor 2> to check the safety circuit status. For details of the safety circuit monitor, refer to the Operation Manual.

CAUTION
Before working on the safety circuit wiring, make sure that the controller power is turned off. If the wiring touches the enclosure while the controller power is on, the emergency stop circuit fuse will blow.

[NOTE]

1. This error does not occur if the safety circuit is configured as a single circuit.
2. This error can be reset only when the single and double circuits are both open (OFF) at the same time. If either circuit is closed, the error cannot be reset.
