FRINDS,

WE ARE NEW TO THIS MACHINE. WE COULD ABLE TO SWITCH ON THE CONTROLLER,DO REFERENCING EVERYTHING FINE.

BUT FREQUENTLY WE ARE GETTING THE ALARM APC CHECK RACK-0 FOR OVERLOAD.BUT IN THE MACHINE THERE ARE RACKS FROM 1-6.

WE DO NOT HAVE THE ELECTRIAL DRG.

HOW TO PROCEED.

Not knowing the machine, the APC functions are controlled by a "smart brick", an I/O device. It is probably located in an electrical box about 12" x 12" x 4". All the solinoid cables, switch cables etc. will be plugged into it. I have seen problems with vibration loosening connections. I have also seen heat being a problem. If all connections are good you will probably need to replace the unit.

Check all connections and reseat the boards in the rack, this is a common problem with the 2100 controller, reseating the boards fixes lots of things.

Check your 24 volt power supply. We had same problem blown fuse on supply.

Have you found the issue, this post is a bit dated.
Very familiar with the APC Rack setup and Smart Brick application.
