Status em.stop input signal not equal to test output: T2

Was bedeutet 231-E002 ?

This error indicates a discrepancy between the signal level of the test output 'T2' and the 'Emergency Stop' input of the CC controller. Specifically, for CC424, this refers to the '-NE2' signal, and for CC61xx, the '-ES.B' signal. This suggests a wiring error in the emergency stop circuit or a fault in the safety module.

• The signal level of the test output 'T2' differs from that of the 'Emergency Stop' input of the CC.
• Wiring error in the emergency stop circuit or test output circuit (e.g., short, open circuit).
• Faulty emergency stop button or associated safety relay/module.
• Internal hardware defect in the CC module.

1. 1

   Check the wiring connections for the test output 'T2' and the Emergency Stop input (specifically '-NE2' for CC424 or '-ES.B' for CC61xx) for any breaks, shorts, or loose terminals.

2. 2

   Measure the signal levels at both the 'T2' test output and the corresponding Emergency Stop input of the CC to identify the point of discrepancy.

3. 3

   Verify the functionality of all emergency stop buttons and their associated safety relays, ensuring they operate correctly.

4. 4

   Perform a continuity test on the Emergency Stop circuit wiring to ensure it behaves as expected when E-stop is pressed and released.
