sinan78

Hi

We have faced a problem about Emergency Stop Chain on C5.3 controller.

APTBE board controls the Emergency Stop Chain.

LED 1 , 2 ,3 ,4 light but LED5 doesn't.

LED5 light when no EMS from the Teach Pendant. But we have also jumpered ES button on the TP.

I need your desperately help.

Best Regards
