Troubleshooting

Device does not respond when a button is pressed

Verify that the power supply to the controlled machine is on. Check all electrical connections to ensure they are secure and correctly wired according to the machine's schematic. Inspect the button mechanisms for any physical obstructions.

Motor runs continuously or does not stop

Examine the wiring of the NC and NO contacts for both the 'raise' and 'lower' buttons. Ensure there are no short circuits or incorrect connections. Verify that the machine's control relay or contactor is functioning correctly.

Buttons feel stiff or do not return to their original position

Inspect the buttons and the internal mechanism for dirt or debris. Clean the affected area gently. If the problem persists, the internal mechanism may need to be replaced.

Intermittent operation or unreliable control

Check all screw terminal connections for tightness. Ensure the operating environment is not causing interference. Inspect for any physical damage to the wiring or the enclosure.
