Hi Piscean 2010, I am also having some issues with E/R module. Can you provide the procedure to test procedure sheet is to verify/test main DC output, precharging circuit, main contactor operation, IR modules I/O signals etc. etc.

At the machine we get alarm RELAY NOT SWITCH ON. But when we test the E/R by itself it work ok.

Your help is appreciated.

When you apply 3 phase AC input & get 600V DC output, please check if terminal 111 & 113 is closed & terminal 111 & 213 is open. This will test that main contactor operation (& 600 V DC output supply is not output due to pre charging circuit only).

But if no any LED i.e. GREEN, YELLOW is ON then to be 100% sure, you need to check IR module on load i.e. its regeneration circuit operation needs to be check on load.

The attached test procedure sheet is to verify/test main DC output, precharging circuit, main contactor operation, IR modules I/O signals etc. etc.
