Failure codes. (tab.7)
Failure
code
Fault type Fault cause Notes
bAF broken battery
the battery is not fully charged, the
battery is not connected,
burnt battery fuse check the connection and the
battery fuse, read the battery
charge current
bLE discharged battery
indicates battery voltage drop
below 10.5V
during battery-assisted
operation, the PSU will start the
countdown to the battery
disconnection
o1E
too low voltage at the
OUT1 output
Uout <9.5V
output IOUT1>3A overload
remove the cause, disconnect
the load and connect after 30 s
o2E
too low voltage at the
OUT2 output
Uout <9.5V
output IOUT2>3A overload
remove the cause, disconnect
the load and connect after 30 s
UHi
too high voltage,
indicated
Uout > 14.5V damaged voltage regulator, wrong
setting of the P1 trimmer
potentiometer
check the setting of the P1
trimmer potentiometer
oHE
battery overheat
PSU circuits overheat, regulator
overheat, damaged temperature
detector , detector not connected
check the load balance,
ventilators, temperature
detectors’ connections, ensure
the enclosure ventilation
SEr regulator error
over voltage protection was
activated, a break in the regulator
circuit
unplug the PSU, contact the
service center
AHE
too high supply voltage
AC >250V
check the voltage of 230V
mains supply
nAc
no voltage or too low
network voltage Check the mains fuse of the
transformer
rSt PSU restart
AC supply on, launching the PSU
with the START button
3.2 Acoustic indication.
Emergency situations are acoustically indicated by a buzzer. The frequency and the number of signals
depends on a fault type (Tab.8). The acoustic indication is off after removing the ZB jumper.

Nr Description
Situation
1
1 signal per 13s, battery-assisted
operation
no 230V AC supply
2
1 signal per 13s, mains operation battery fault
3
continuous indication failure, e.g. output overload
4 5 signals finishing the battery test
5 18 signals initiating the battery test
3.3 Technical outputs.
The PSU is equipped with indication outputs:
•
BS - absence of AC supply output: - OC type output that indicates absence of AC supply. In normal
status, with 230V AC supply, the output is ground fault (L state – 0V). In case of power loss, the PSU will
switch the output into high impendence state, hi-Z, after a time period set by the Z1,Z2
jumpers (see
Tab.1).
