Two-Hand Discrepancy Error - Input Pair 2

What does FB TWOHAND Bit 1 mean?

A discrepancy has been detected within the two channels of input pair 2 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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Review the discrepancy time parameter for input pair 2 in the FB TWOHAND configuration; adjust if slight timing variations are acceptable for the application.

2. 4

   Instruct the operator to actuate the two-hand control correctly and simultaneously, observing their technique.
