SG410/AC410 Halt Code 88
No I/O's nor Modules Mounted in the Rack, I only Have Connected Sb171 and the DSSR 122.
So I want to Know the Halt Code 88 because I searched at the Code but I couldn't find it?
Thanks a lot
Halt code 88 indicate fatal hardware error.
I guess you get this code even before you insert the program card.
Missing 24 Volt could be one reason.
1. Check the 24 Volt 6.3 A glass fuse in the fuse holder on top of the gray xxxx terminal next to the DSSR 122 regulator
2. Make sure that the small circuit boards inside the PM510 "CPU box" are properly mated with their back plane.
To check point 2, you must remove the front cover.
