11. By means of
STOP
button [3] activate or deactivate the dynamic battery test (Tab.2). Test deactivation
triggers also deactivation of signalling of a battery failure at the AW output, but the circuit protecting the battery
from the complete discharge is not isolated.
12. Perform the PSU test: optical and acoustic signalling (Tab.2) of technical outputs through:
-
disconnection of 230V AC supply:
optical and acoustic signalling – prompt, BS technical output – after
the period of time set by Z1 and Z2 jumpers (Tab.3)
- disconnection of the battery
: optical and acoustic signalling and AW technical output – after the battery
test is performed (~ 20 min)
13. Set at
ZB
jumpers [2] (Fig 3) whether acoustic signalling shall be activated (inserted jumper) or deactivated
(removed jumper).
14. Check consumption of current by receivers so that the total current efficiency of the PSU is not exceeded.
15. Delete the failure memory of the PSU.
16. After installation is completed and operation of the PSU is checked, the casing can be closed.
3. Signalling of the PSU operation.
The PSU has a panel with buttons and a 3-digit LED display. It makes it possible to read out main current and
voltage parameters of the PSU and to review failures. The panel buttons are used to select and confirm the
parameter that shall be currently displayed.

Display of actual PSU failures, button repressing causes display of another failure
(if there are more failures within the same time),
Pressing
in the review mode of the failure memory causes erasing of the
failure memory
a red LED indicating a failure
a green LED indicating AC supply voltage, (lights – AC supply, flickers – battery
supply)
