GENMA Maintenance · Emergency & Troubleshooting | Emergency Stop Verification

Depending on the model and configuration, GENMA machines have emergency stops at key locations — travel gear, operator cab, electrical room, power room, winch room, gantry auxiliary cabinet, generator set, and more (refer to your machine's actual configuration for exact count and locations). The emergency stop system is the last line of defense. It's rarely used, but when needed, it must work reliably.

Periodically verifying that the system truly stops the machine when pressed is one of the most basic parts of emergency preparedness.

1. Before you verify

• Motor is off

• Main power switch is on

• No personnel in the surrounding area

2. How to verify

1.Press the emergency stop

2.Check that the touchscreen turns off

3.Confirm the entire machine comes to a complete stop

Test every emergency stop one by one — testing just one doesn't mean they're all working.

3. Verification interval

Check the function of each emergency stop every 50 hours.

4. What if something's wrong?

If the touchscreen doesn't turn off, or the machine doesn't fully stop after pressing the emergency stop, there may be an issue with the emergency stop circuit. In that case:

• Stop using the machine

• Check for loose wiring at the emergency stop

• Contact your GENMA service engineer for diagnosis and repair

Verification doesn't require complex tools — a full cycle takes just a few minutes. Make it part of your 50-hour routine inspection. If you have any questions about your emergency stop configuration or verification method, feel free to reach out to your GENMA service engineer.
