6.4.2. LCD screen
– current parameters
.
To set the screen, press the
„ESC” button, use the „<” or „>” buttons to choose the
icon and press the
„SET” button to confirm.
The screen displays electrical parameters and the status of the technical outputs during operation.
Illumination of an element informs about an activation and reflects the status of LEDs on the PCB of the PSU (see
Table 1, [10]).

AC power indication
open= AC power failure
closed = AC power
– O.K.
PSU
– PSU failure indication
open= PSU failure
closed = PSU working correctly O.K.
APS
– battery failure indication
open= battery failure
closed = battery O.K.
ALARM
– collective failure indication
CAUTION!
The set of contacts shows a potential-free
status
of the relay, which corresponds to power supply failure.
EXTo
– relay output status indication
