3. Operating status indication.
3.1. LED indication.
The PSU has 22 LED lights at the front panel:
GREEN LED:
on – the PSU is supplied with 230V AC
off – no 230V AC supply
GREEN LED:
on – DC voltage at the output of the switch mode PSU
off – no DC voltage at the output of the switch mode PSU
RED LED:
on – failure
off – no failure
RED LED:
ON – too high temperature of the switch mode power supply
(>70°C)
OFF – standard temperature of the switch mode power supply
RED LED:
on – battery voltage <11,5V
off – battery voltage >11,5V
GREEN LED:
on – DC voltage in the AUX1…AUX16 output
off – no DC voltage in the AUX1…AUX16 output
GREEN LED:
on – DC voltage in the DVR output
off – no DC voltage in the DVR output
3.2. Technical output.
The power supply is fitted with the
ALARM
output of collective failure (relay type). A collective failure can
be triggered by the following events:
- 230V AC mains power failure
- Activation of the PTC polymer fuse in the camera power supply circuit
- Activation of the F
DVR
glass fuse in the recorder power supply circuit
- Failure of the switch mode power supply
- Too high temperat
ure of the switch mode power supply (>70°C)
- Low battery voltage (<11,5V)
Fig. 4. Electrical diagram of the ALARM collective output of failure.
CAUTION!
In Fig.4 the set of contacts shows a potential-free status of the relay, which corresponds
to power supply failure.
