Troubleshooting AMX
Error Number
system is switched from an “OFF” state to “ON” state
Error Code / System Message
Error Question
How do I troubleshoot this AMX-4 Series issue: When the AMX4/AMX4+ system is switched from an “OFF” state to “ON” state, a peak inrush current spike greater than the 10A rating of the K215 relay contacts was observed. This spike has the potential to weld the contacts?
Short Answer
The solution is to replace the CONDOR power supply (Vendor part# MDSP1733, GE part# 2318476) with the modified CONDOR/SL power supply (Vendor part# MDSP1733A, Orderable GE part# 2366118). The new supply has an inrush current profile that is much smaller than the existing supply. Refer to Service Note 30004.
Possible Causes
Problem: When the AMX4/AMX4+ system is switched from an “OFF” state to “ON” state, a peak inrush current spike greater than the 10A rating of the K215 relay contacts was observed. This spike has the potential to weld the contacts of the K215 relay. This welding action causes the system to remain in the “ON “state even after switching the state to “OFF.”
