Hi All,
We recently purchased a used ABB IRC5 controller with IRB140 robot. I did a complete clear of the controller and reinstalled the original boot files. When I restarted the system, I came up with a number of issues. One is a problem with the axes revolution counter not being updated (10036/20032) and a battery backup alarm (38200) but the main one I'm concerned with is the Safety Guard State alarm (10012). I've checked my status LEDs on the interface board and the LED for AS, GS, ES and SS are all on (orange), so it seems like the system should work okay.

For some reason I still keep coming up with the same Safety Guard State alarm. I press the "Motor On" pushbutton on the front panel and even with the deadman switch depressed, the alarm won't clear. I believe I will be able to clear the others once I'm able to move the axes to their home positions and replace the batteries.

Any advice/help would be appreciated. I have lots of experience with Fanuc robots but, other than doing a bit of work in college, the ABB robots are a bit new to me.
Thanks for your help!

Nevermind, I'm a moron...

I was pressing the deadman switch on the side of the TP but didn't realise it was a two-stage switch and I had it depressed way too much. Once I got into the I/O screen and saw that the EN1 and EN2 signals were missing, I knew right away.

I couldn't believe how hard it was to press the deadman and didn't understand why ABB would make it so difficult. Turns out, they made it just right!  icon_wink

She's moving now and I'm ready to get into the programming.
Thanks
