Two-Hand Discrepancy Error - Input Pair 1
Beckhoff · TwinSAFE Logic FB
What does FB TWOHAND Bit 0 mean?
A discrepancy has been detected within the two channels of input pair 1 for the FB TWOHAND. This means the redundant hand actuation signals are not synchronizing correctly, indicating a potential issue with the two-hand device, its wiring, or incorrect timing. This will prevent safe two-hand operation and put the machine into a safe state.
Complete Troubleshooting Guide
- 1
Inspect the wiring of input pair 1 from the two-hand control device, ensuring both channels are correctly connected and free from damage.
- 2
Verify the functionality of the pushbuttons or sensors for input pair 1; ensure they actuate simultaneously and reliably.
- 3
Review the discrepancy time parameter for input pair 1 in the FB TWOHAND configuration; adjust if slight timing variations are acceptable for the application.
- 4
Instruct the operator to actuate the two-hand control correctly and simultaneously, observing their technique.
