AC OK:
on
– The PSU supplied with 230V AC voltage
off
– no 230V AC mains supply
DC OK:
on
– DC voltage at the AUX output
off - no DC voltage at the AUX output
BAT OK:
on – battery voltage
U
BAT
> 11,5V
off – battery voltage
U
BAT
< 11,5V
The shock protection circuit shall be done with a particular care: the yellow and green wire
coat of the power cable should be connected to the terminal marked with the PE
symbol. Operation of the PSU without the properly made and fully operational shock
protection circuit is UNACCEPTABLE! It can cause damage to the equipment or an electric
shock
4. Connect the receiver cables to the AUX terminals at the power supply board.
5. If needed, connect the device cables to the technical outputs:
- EPS; technical output indicating AC power failure
- PSU; technical output indicating PSU failure.
- LoB; technical output indicating low battery voltage
- Optional installation of the MPSBS relay module changing technical outputs of the OC type to relay type
(page 9, section. 3.3)
6. Use the I
BAT
jumper to set the maximum battery charging current, taking into account the battery
parameters.
7. Use the P
BAT
jumper to set to turn on/off deep discharge battery protection U<10V (+/-5%).
Deep
discharge battery protection is ON when the P
BAT
jumper is OFF.
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 corresponding LEDs on the power supply PCB should be ON: red AC
and green AUX. The yellow LB LED should light up while charging.
10. Check the output voltage (the power supply voltage without load should be 13,6
V ÷ 13,9V, 11V ÷ 13,8V
while battery charging). If the voltage requires adjustment, use the V
ADJ
, potentiometer while monitoring the
voltage at the AUX output of the power supply.
11. Check the current consumption of the receivers, taking into account the battery charging current, so as not
to exceed the total current efficiency of the PSU (section 1.1).
12. Close the cover after installing and checking the operation of the power supply.
3. Power supply operation indication.
3.1 Optical indication.
The PSU is fitted with 3 LED lights at the front panel
:
Additionally, the PSU is fitted with 3 LED lights indicating the operating status: AC, LB and AUX at the PCB
of the PSU:
AC - red LED
: is permanently illuminated during normal operation (AC power ON). No AC power is
indicated by turning off the LED.
LB - yellow LED
: indicates battery charging. The light intensity depends on the charging current.
AUX
-
green LED:
indicates DC power status at the PSU output. During normal operation, it is permanently
illuminated. In case of short-circuit or output overload the LED is off.
