3. Operating status indication.
3.1. LED indication.
The PSU has 11 LED lights at the front panel:
GREEN LED:
•
on – the PSU is supplied with 230V AC
•
off – no 230V AC supply
RED LED:
•
on – failure
•
off – no failure
RED LED:
•
ON – too high temperature of the power supply (>70°C)
•
OFF – standard temperature of the power supply
GREEN LED:
•
on – DC voltage in the AUX1…AUX8 output
•
off – no DC voltage in the AUX1…AUX8 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 circuits
- Too high temperature of the power supply (>70°C)
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.
