Status messages:
This message group simply shows the UPS STATUS at the upper line of LCD PANEL.
RECTIFIER START !
:
UPS started the rectifier
INVERTER START !
:
UPS started the inverter
MAINT SWITCH ON !

Maintenance bypass switch is on
MANUEL BYPASS !
:
Load is transferred to mains manually
STATUS ALARM !
:
Alarm status
STATUS NORMAL !
:
UPS is operating
EMERGENCY STOP !

STATUS FAULT !
:
Fault status
CLOSE BATT.CB !
:
UPS is waiting for battery CB close
STATUS WARNING !
:
Warning message is valid on LCD panel
RECTIFIER START :
At start up the UPS controller board check for input voltage, frequency, battery voltage for starting, if these
parameters normal UPS starts.
INVERTER START :
If the inverter stops controller board tries to start again, during inverter start this message appears on first line of
LCD PANEL.
MAINT SWITCH ON:
Maintenance bypass switch is connected from input to the output of UPS directly, controller stops inverter for
accidental short circuits between mains voltage and inverter output. If the user turn off maintenance switch
inverter starts again.
EMERGENCY STOP :
If an external EPO switch is installed to system (connected to interface board), to stop all UPS parts (rectifier,
static bypass, inverter, etc….) is possible. After pressing EPO switch all parts of the UPS stops, for restart turn
off S1 (inverter input) switch and turn on again.
FAULT STATUS :
In some cases controller checks events but can not find solutions, in this case controller decide to stop system
