• Scanning of sensors
The unit now starts automatically scan-
ning the sensor inputs, after which the
following screens are shown. If the unit
finds a correctly connected sensor, it
automatically continues searching on the
next channel, i.e. 1, 2 and 3.

• Sensor not detected
If an input does not have a connected sen-
sor, this can be confirmed in this routine.
The key is used to approve the response
marked -YES-.

Not connected. OK ?
-YES-
If a sensor is not detected at an input
despite the sensor being connected, the
same message as the one shown above
will appear on screen, and in this instance
it is necessary to correct any incorrect
connection (see Troubleshooting).

Sensor function control
Before any tests are made activate the ser-
vice mode of the unit. This must be done in
order to detect alarms without filtering/de-
lay. Especially the sludge probe can not be
tested properly if the service mode is not
activated. In the main menu press the
RESET key at the same time for 3 seconds.
The following screen will appear:
> SERVICE
DATE-TIME
INPUTS
RELAY OUTPUTS
Activate the service mode by pressing
for 3 seconds. The unit will now show a
number on the screen indicating which
probe is being scanned. The unit remains
in service mode for 30 minutes and returns
automatically into normal mode.
All connected sensors should be tested af-
ter installation. The following must be done
in order to test the various sensors:
• Capacitive layer sensor type WGA-ES4
is lifted up out of the water in order to
trigger an alarm.
• Damming sensor type WGA-R6-S is dipped
in water in order to trigger an alarm.
• Sludge sensor type WGA-ES8 is lifted
up into air or pushed into sand/sludge in
order to trigger an alarm.
Note that it may take up to approx. 60 sec-
onds to trigger an alarm. This is because
the unit requires a number of scans in line
with the alarm status of the sensors in
order to trigger an alarm. This is done to
minimise the risk of false alarms when the
alarm level is close to the sensor.
• Testing of level sensor WGA-ES4
Lift the level sensor up into the air and
wait. The following screen should be
displayed within approx. 60 sec.
