Additionally, the PSU is fitted with LED lights inside the enclosure – see Fig. 2 and 3:
- L
AC
red LED (Fig. 2, component 1) is permanently illuminated during normal operation (AC power ON).
No AC power is indicated by turning off the L
AC
LED.
- L
IN
green LED (Fig. 2, component 1) indicates DC voltage at the PoE module input. During normal operation (DC
supply) the LED is permanently illuminated. No DC no DC voltage at the module input is indicated by turning off the
L
IN
LED.
- L
FPS
red LED (Fig. 2, component 10) is not illuminated during normal operation (no failure). In case of activation of
the short circuit / overload protection at any output, the LED is permanently illuminated.
- L1 ÷ L4 green LEDs (Fig. 2, component 5) indicate voltage at the individual outputs of the module (L1 for AUX 1
etc.). Activation of the short circuit / overload protection of a given circuit is indicated by turning off one of the Lx
LEDs.
3.1. Technical outputs.
The PSU has the following indication outputs:
•
FPS – technical output of the PSU status:
- OC type output indicating failure (short-circuit, overload). During normal operation, shorted to ground – L
state (0V). In case of power loss, the FPS technical output is switched into hi-Z state (high impedance) at least
at one of the AUX outputs.
Fig. 5. Electrical diagram of the OC output.
- relay output. In case of failure, relay contacts are switched automatically.
Fig. 6. Electrical diagram of the relay output
CAUTION! The arrangement of contacts at the figure 6 shows a potential-free status of the relay,
which is equivalent to a state with no voltage at any of the AUX1 ÷ AUX4 outputs.
•
TAMPER – output indicating enclosure opening: - volt free contact input indicating the status of the
power supply doors, PSU closed: contacts closed (NC), PSU open: contacts open (NO).
