Two-Hand Discrepancy Error - Between Pairs

What does FB TWOHAND Bit 2 mean?

A discrepancy has been detected between the actuation times of input pair 1 and input pair 2 for the FB TWOHAND. This means the operator is not actuating both hands simultaneously within the allowed time window, or there's an issue with the timing of the two-hand control device itself. This fault ensures true simultaneous actuation for safety and stops the machine.

Complete Troubleshooting Guide

1. 1

   Observe the operator's technique for actuating the two-hand control; retrain if necessary to ensure simultaneous pressing of both pairs.

2. 2

   Check the physical distance and ergonomic setup of the two-hand control buttons/sensors to facilitate simultaneous actuation.

3. 3

   Review the discrepancy time parameter *between* input pairs in the FB TWOHAND configuration; adjust if the application legitimately allows for a slightly larger window.

4. 4

   Verify the response times of both two-hand input devices and their associated wiring for any delays.
