RED LED:
twinkling – indicates failure status
( Tab.7)
GREEN LED
:
illuminating – the PSU is supplied with 230V AC power,
correct operation
twinkling – no 230V AC power, battery-assisted operation
8. Mount the battery in the battery compartment of the enclosure (Fig. 3). Connect the batteries with the PSU
paying special attention to the correct polarity.
9. Switch on the 230V AC supply. The green AUX and yellow LB LEDs on the power supply PCB should be
ON while charging the battery.
Output voltage of the PSU, without load U = 13,8V DC.
During battery charge, voltage can amount to U = 11
V÷13,8V DC
10. With the
STOP
button, initiate or finish a dynamic battery test.
Deactivating the test turns out the PSU failure indication at the APS FLT, output, but it does not affect the
protection system against complete battery discharge.
11. Run the PSU test: check the LED and acoustic indication (Tab. 7), technical output; through:
-
cutting off the 230V AC current:
LED and acoustic indications
– immediately; the EPS FLT technical output
- after some time, determined by
T
AC
pins.
- battery disconnection:
LED indication, acoustic indication and the APS FLT
– technical output – after a
battery test have been completed (~10min).
12. Use the
jumper to enable or disable acoustic indication.
13. Once the tests and operation control have been completed, the enclosure can be locked.
3. Operating status indication.
The power supply unit features LED and acoustic status indication. PSU status can be remote-controlled by
two technical outputs.
3.1 LED indication.

Notes
1
broken battery
the battery is not fully charged,
the battery is not connected,
burnt battery fuse
check the connections and the
battery fuse
2
discharged battery

too low output
voltage U <10V
output overload
remove the cause,
disconnect the load and
connect after 30-60 s
4
too high output
voltage
Uout > 14,5V
damaged voltage regulator,
wrong setting of the P1
potentiometer
