3.3 Technical outputs.

The PSU indication outputs:

EPS FLT - technical output indicating 230V AC power failure.
The output indicates 230V AC power failure. Under normal status – with the 230V AC supply on, the output
is shorted to ground GND. In case of power failure, the PSU will switch the output into hi-Z high impedance
state after a time set by the T


PSU FLT - output indicating PSU failure.
The output indicates PSU failure. Under normal status (correct operation) the output is shorted to ground
GND. If there is no DC voltage at the output (e.g. short circuit), the output is switched into hi-Z high
impedance state.
PSU failure can be caused by the following events:
- Short circuit at the output
- low Uaux output voltage, less than 10V
- high Uaux output voltage, higher than 14,5V
- the PTC output fuse activation
- exceeding the rated current of the PSU
- activation of overvoltage protection OVP
- internal damage of the PSU
- defective or low battery
- battery fuse failure
- no continuity in the battery circuit

LoB - output indicating low battery voltage.
The output indicates low battery voltage. Under normal status (U
