6.5. Technical outputs.
The PSU is equipped with galvanically isolated indication outputs changing status after a specified event:
EPS FLT
– output indicating 230V AC power loss
.
The output indicates 230V AC power loss. Under normal status, with the 230V AC power on, the output
is closed. In case of power failure, the PSU will switch the output into the open position after a time lag
determined in the „ Delay time for EPS output” menu (see section 7.2.4).
APS FLT
– output indicating battery failure.
The output indicates a failure in the battery circuit. Under normal status (during correct operation) the
output is closed. In case of failure, the PSU will switch the output into the open position. Failure can be triggered by
the following events:
- faulty batteries
- undercharged batteries
- disconnected batteries
- high resistance of the battery circuit
- battery voltage below 23V during battery-assisted operation
- blown battery fuse
- no continuity in the battery circuit
PSU FLT
– output indicating PSU failure
.
The output indicates the PSU failure. Under normal status (during correct operation) the output is
closed. In case of PSU failure, it will switch into the open position. Failure can be triggered by the
following events:
- U
AUX1, AUX2
output voltage below 26V
- U
AUX1, AUX2
output voltage over 29,2V
- battery charging circuit failure
- blown F
AUX1
or F
AUX2
fuse
- exceeding the rated current of the PSU
- activation of overvoltage protection OVP
- mains supply voltage over 254V AC
- mains supply voltage below 195V AC
-
to high battery temperature (>65°C)
- temperature sensor failure, t < -
20°C or t > 80°C
- enclosure opening
– TAMPER
- internal damage of the PSU
- LCD panel damage
