3.2. Technical output.
The controller is fitted with the ALARM technical output of collective failure. The collective failure can be
triggered by the events presented in Table 6.
Fig. 6. The electrical diagram of the ALARM output of collective failure.
CAUTION! In Fig. 6 the set of contacts shows a potential-free status of the relay which corresponds
to a failure.
3.3. Acoustic indication.
The failure status is also signaled acoustically by means of a piezoelectric indicator (in accordance with
Table 6). Acoustic indication can be disabled with an ON/OFF switch .
Switch in the upper position, the indication is ON
Switch in the lower position, acoustic indication is OFF

4. Maintenance and operation.
4.1. Automatic battery test
The battery controller performs a battery test every 5 minutes, temporarily stopping the charge process,
while measuring voltage at the battery terminals and the resistance of the battery circuit. The test can also be
started manually by pressing the "TEST" button on the front panel, but not more often than once every 1 minute.
The activation or deactivation of the test will be confirmed acoustically (see Table 6).
4.2. Short circuit of the controller output/reverse connection.
The BAT controller output is additionally protected against short circuit by a fuse (box); in the case of
damage, it should be replaced with a fuse of the same type. The fuse is located inside the unit.
4.3. Maintenance.
The battery controller does not require any specific maintenance; however, it should be cleaned with
compressed air if used in dusty conditions.
