Dear all, I am having ABB IRB140 (material Handling application type) Robot with IRC5 controller. Generally, At starting stage I am able to control the robot in both automatic and manual mode. But recently after long time switching on controller the robot cannot run in auto mode operation. According to my knowledge when am diagnose this error, I found an issue with safety light curtain sensor not working (led indicator not receiving signal from IRC5 controller) properly. 

can anyone please help me how to solve this problem.

    The IRC5 Auto Stop (AS) circuit must be broken by the light curtain - are the two orange LEDs on the safety (panel) board in the IRC5 on or off?

    Is the light curtain being powered from the controller - perhaps the power supply or fuse is faulty?
