17-4 Receiver Troubleshooting

If the yellow INTERLOCK LED is blinking:

Check the configuration for External Device Monitoring. If EDM is inactive

(via receiver dip switch), the input (red wire) must be connected to system

ground. If EDM is active, the input must be connected to the normally

closed contacts of the control relays of the guarded machine or the monitor

terminal of the safety relay unit. Please refer to

SECTION 11 Connection

to the Machine Control Circuit for an example.

Make sure both selector switches in the receiver endcap have been set

properly and identically. Please refer to chapter

7-2 Operating mode selec-

tion for further information.

Verify the power supply is within the specified limits (+24V ±20%).

Verify the light curtain is properly connected to the control relays of the

guarded machine. If the light curtain is not intended to be connected to

control relays, see

SECTION 12 Muting for further information.

Verify the control relays are within operating limits of the safety outputs.

Verify the cable lengths from the light curtain to the control relays are within

specified limits.

If this does not solve the problem, please contact your local Omron distrib-

utor or the European Repair Center.
