7.8. ALARM, ALERT AND EVENT TABLES
7.8.1. UPS alarm table
When a fault occurs, the UPS will switch to fault mode, the
acoustic alarm will sound continuously and the alarm will appear
on the main screen.
Below is a table with all of the possible alarm messages that can
appear on the screen and their descriptions.

USER MANUAL
BUS start failure. When the bus voltage can't reach the setting value in 30s, the fault signal
will be displayed.
When one of the following conditions occurs, the fault signal will be displayed. +Bus voltage
keeps higher or the –BUS voltage keeps lower than normal.
When +Bus voltage keeps lower or the –BUS voltage keeps higher than normal, the fault signal
will be displayed.
When the difference between the ±Bus voltage absolute value, the fault signal will be sent.
PFC over current. When the current of PFC/Boost is over current, the fault signal will be display.
Inverter soft start failure. Inverter voltage can't reach the setting value.
High inverter voltage. When INV voltage keeps higher than normal, the fault signal will be
displayed.
Low Inverter Voltage. When INV voltage keeps lower than normal, the fault signal will be dis-
played.
Inverter R output (line to neutral) short circuited. When INV phase R output voltage keeps lower and
output current keeps higher than normal, the fault signal will be displayed.
Inverter S output (line to neutral) short circuited. When INV phase S output voltage keeps lower and
output current keeps higher than normal, the fault signal will be displayed.
Inverter T output (line to neutral) short circuited. When INV phase T output voltage keeps lower and
output current keeps higher than normal, the fault signal will be displayed.
Inverter R-S output (line to line) short circuited. When INV phase R-phaseS (Line to line) voltage
keeps lower and output current keeps higher than normal, the fault signal will be displayed.
Inverter S-T output (line to line) short circuited. When INV phase S phase T (Line to line) voltage
keeps lower and output current keeps higher than normal, the fault signal will be displayed.
Inverter R-T output (line to line) short circuited. When INV phase T phase R (Line to line) voltage
keeps lower and output current keeps higher than normal, the fault signal will be displayed.
Inverter R negative power fault. When the output power on the INV phase R terminal is over-
power, the fault signal will be displayed.
Inverter S negative power fault. When the output power on the INV phase S terminal is over
power, the fault signal will be displayed.
Inverter T negative power fault. When the output power on the INV phase T terminal is over
power, the fault signal will be displayed.
Inverter relay open. The inverter voltage detection is normal, but the output voltage difference
form the inverter voltage.
Line wiring fault. INV relay and bypass SCR open, but output voltage is higher than normal.
Parallel communication failure. When the parallel communication between the UPSs is inter-
rupted, the fault signal will be displayed.
Over temperature. The temperature of sink is over the protection setting.
DSP communication Failure. When the communication between the INV control board and the
PFC control board is interrupted, the fault signal will be displayed.
The load is over the settings for certain time.
Charger fault. The UPS detect the charger current more than 1.5A when power on the UPS.
Model fault. The UPS can not identify the right model.
