If the UPS status is on-line or if the UPS status is discharge, the load will be protected during a utility outage.If the UPS status is automatic voltage regulate (AVR) or if the UPS status is bypass, the load will be powered but not protected from a utility outage.If the UPS status is shut down, the load will not have power for a certain amount of time regardless of the utility source.

Message    Event Type    UPS Status    Description    
!!Code Area modified - checksum bad sector %d     A     B     A problem has been detected with the controller program. The program has been reloaded. (The controller was reset.)    
!!ERROR!! DEADLINE TIMEOUT!!     A     B     The main control board has been reset from a frozen state.    
!!ERROR!! EXTENDED TIMEOUT!!     A     B     The message occurs if the PPC does not write to a register on the FPGA in a minute. The usually meaning is that the boot monitor is in a failure state, such as, the RAM test failed. The FPGA will reset the APC to try and fix the problem at that point.    
!!ERROR!! Memory Access Timeout     A     B     The main control board has detected a memory access problem.    
*** Low 24V Supply Detected. ***     A     B     The main control board has detected a loss of 24 VDC control power.    
*** Resetting the APC Board ***     A     B     The main control board has been reset.    
_ open while MMU regulating error     A     B     The input or output contactor opened while the UPS was online without a command from the APC.    
_ sensing failed     A     B     Contactor position sensing has failed.    
All internal PCB data locks present     L     B     Start-up sequence, PWAs are communicating with main controller    
APC1 _ PS Failed: _V (CNT: 0x _)     A     B     (New APCs only: 30158-2) The controller has detected a problem with one of the power supplies (+5, -15, or +15VDC)    
At Speed standing by at _ RPM     L     O     The flywheel is at full speed and ready to support load    
Bearing Install Date     L     NC     A new bearing install date has
