Common Teach Pendant Issues

Does this look familiar? Even with careful use, accidental drops, excessive pressure, or impacts can damage the keypad membrane, connectors, lock mechanism, or emergency stop button, leaving your teach pendant in a "battle-worn" state. Many users continue using it until it completely fails.

Other frequent faults include:

• Black screen/unresponsive operation

• Flickering, cracked, or blank display

• Freezing at startup, frequent E-stop alarms, lock head errors

• Damaged keypad chips, motherboard failures, or constant yellow indicator lights
