106 Single Stop
Command to stop itself has been given to UPS which is operating in
paralel mode separately from paralel system.
107 Master Changed UPS became master device in paralel system.
108 Par. Bus ID Collision
ID value of one or more UPS is the same as each other in parallel
system.
109 Output Offset Err.
One or more phase of slave UPS’ output is not connected to master UPS
in Parallel systems.
110 Bypass Short Circuit
Short‐circuit current limit has been exceeded in the maintenance
bypass mode. UPS is shut down.
111 RMS output Failure The value of output voltage is out of the limits. UPS will be shut down.
112 Stop All Units Stop all units command was given via front panel.
113 Float Charge Mode
UPS charge mode has switched to the standby mode at the constant
voltage from constant current mode.
