5.5 Acoustic indication.
Emergency situations are acoustically indicated. The frequency and the number of signals depend on an
event type (see chapter. 5.4.6). The acoustic indication is off after removing an appropriate jumper (fig. 2, [5]).

5.6 Technical outputs.
The PSU feature indication outputs, with galvanic isolation, which change their state if any of the following
events occur:
EPS FLT - output indicating 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. 6.2.4).
APS FLT - output indicating battery failure.
The output indicates a failure in the battery circuit. Under normal status (during correct operation) the
output is close. In case of a failure the PSU will switch the output into the open state. Any failures can be
triggered by the following events:
- a faulty or undercharged battery
- battery voltage below 11,5V during battery-assisted operation
- battery fuse failure
- 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 close.
In case of a failure the PSU will switch the output into the open state. Any failures can be triggered by the
following events:
- low output voltage Uaux<11,8V
- high output voltage Uaux>14,7V
- high battery voltage Uaku>14V (during battery test)
- polymer fuse PTC activation
- exceeding the PSU nominal current
- failure in the battery charging circuit
- activation of the over voltage protection OVP
- enclosure opening - TAMPER
- internal damage of the PSU
- EXT IN input activation
The technical outputs have been implemented with galvanic isolation between the PSU’s systems and the
attached devices.
