Slave UPS which is operating in paralel mode can’t reach to master UPS from
CAN bus.If UPS is operating,will be shut down.
UPS which is operating in paralel mode has been given a command to start up
by another (master) UPS.
UPS which is operating in paralel mode has been given a command to stop by
another (master) UPS.
UPS which is operating in paralel mode has been given a command to transfer
the load to bypass line.
UPS which is operating in paralel mode has been given a command to transfer
the load to inverter line.
Slave UPS which is operating in paralel mode has detected a failure of input
current sharing.
Inverter voltage reached needed value after UPS is started up. UPS can feed the
loads through inverter.
Battery temperature is out of defined limits, batteries can be damaged.
EPO key button is pressed.
Battery capacity has decreased below defined “ battery low limit” while UPS
was operating in battery mode.
Parallel RS485 communication between the systems is not available.
OverCurrent in Bypass line.
Reverse phase sequence was detected in mains at the UPS run time.
Over Inverter DC voltage. Loads will be transferred to the bypass line.
One or more phase of slave UPS’ output is not connected to master UPS in
Parallel systems.
Battery temperature is normal.
Positive DC Bus overvoltage.
Negatif DC Bus overvoltage
Short circuit protection is activated for rectifier L1 phase.
Short circuit protection is activated for rectifier L2 phase.
Short circuit protection is activated for rectifier L3 phase.
Command to stop itself has been given to UPS which is operating in paralel
mode separately from paralel system.
UPS became master device in paralel system.
ID value of one or more UPS is the same as each other in parallel system.
Stop all units command was given via front panel.
The error signal is detected on UPS through power source circuit debugger.
Signal is detected from "generator mode input" of dry contact board. UPS will
switch to "generator mode".
