Hello,
We have an YASNAC MRC II controller with SK6 robot, manufacturing date 11-1998 / 502, type ERCS-SK6-NECO, System No. 112134
Robot was inactive for a while.
After restarting, on display shows 3 error messages:
Alarm 2000
Alarm 5040
and Alarm 5090
First two are dedicated for axes calibration and I hope that will be routine to resolve.
But Alarm 5090 is challenging for me. We have 24V DC on power board, two green LED's are on, two connectors are connected but one slot is empty (is it OK?), but I have no any idea on which board I need to have that voltage, actually on which pins?
It could be some fuse, but I don't know where to check.
Is it any suggestion how to solve this issue?
Attached is photo controller.
