Safety Chain 1 Abnormal

Hva betyr SRVO-230 ?

A mismatch has occurred between duplicate safety signals. Specifically, a contact on the chain 1 side (e.g., between EES1 and EES11, or EAS1 and EAS11) is closed, while the corresponding contact on the chain 2 side (e.g., between EES2 and EES21, or EAS2 and EAS21) is open. This condition indicates a potential failure or discrepancy in one of the redundant safety circuits, compromising safety integrity.

• Safety Chain 1 has detected an abnormal condition, interrupting normal operation.
• This indicates a fault in the wiring, components, or configuration of the first safety interlock circuit (e.g., emergency stop buttons, safety gate switches).
• The system has disabled motion to ensure operator safety due to a breach in safety chain integrity.
• Requires systematic checking of all components and wiring associated with Safety Chain 1.

1. 1

   Check any other SRVO-266 through SRVO-275 and SRVO-370 through SRVO-385 alarms issued simultaneously to identify the specific signal with the mismatch.

2. 2

   Take corrective action(s) as described for any concurrently issued alarms.

3. 3

   Do not reset the chain error alarm until the failure is identified and repaired to ensure safety.

4. 4

   After correcting the cause of the alarm, perform the chain error reset procedure as described in the manual.
