4. Operation and use.
4.1 Overload or short circuit of the PSU module output.
The AUX output of the PSU module is equipped with the PTC polymer fuse assisted protection. If the load
of the PSU module exceeds I
max
(load 110% ÷ 150% @25ºC of the PSU module power), the output voltage is
automatically cut off and indicated by the green diode going off. To restore the output power, cut off the output load
for approximately 1 minute.
In case of of the short-circuit to the AUX, BAT output, or incorrect connection of the battery, the fuse F
BAT
in
the battery circuit becomes permanently damaged and the restoration of the voltage at the BAT output requires the
replacement of the fuse.
4.2 Running the PSU module from the battery.
The power supply module is equipped with the button on the PCB allowing to run the PSU from the battery,
when needed. To do that, press and hold the
START
button on the unit board for 1 second.
4.3 Deep discharge battery protection UVP.
The power supply is equipped with deep discharge battery protection (UVP). If the voltage at the battery
terminals drops below 2
0V±0.5V during battery-assisted operation, the batteries will be disconnected.
The battery
protection is on when the P
BAT
jumper is off.
Caution.
It is not recommended to disable UVP since deep discharge of the batteries reduces their ability to
store energy, their capacity and lifetime.
4.4 Maintenance.
Any and all maintenance operations may be performed following the disconnection of the PSU module from the
power supply network. The PSU module does not require performing any specific maintenance measures, however, in
the case of significant dust rate, its interior is recommended to be cleaned with compressed air. In case of fuse
replacement, use a replacement of the same parameters.
