OPERATION

The indicator must indicate the monitoring mode constantly via the green LED Operation]
During a filling of the tank, an alarm is indicated via the red LED Alarm, the integrated buzzer,
and any connected external alarm units when the response level is reached (according to the
adjusting dimension X of the probe) so that the filling procedure can be ended on time.
An alarm is also indicated in case of a possible line disconnection or short circuit in the probe
circuit.
In the case of tanks that are filled with an automatically closing nozzle, filling must be ended
when the BC-2 gives a visual and acoustic alarm.
With the Reset Alarm Sound button, both the integrated acoustic alarm and the Alarm 2
output can be reset (deactivated). The LED Alarm, however, remains in operation. After the
liquid level in the tank sinks (the probe is no longer submerged in liquid, e.g. due to
withdrawal), the indicator switches after approx. 10s to monitoring mode again.
Operation includes MAINTENANCE.
Before each filling process, a FUNCTION CHECK must be carried out by pressing the Test
button (including any connected signalling or control devices with actuator).
Observe assembly instructions for adapter BC-1/BC-2 – AS (connection overfill
prevention device type BC-2 to road tanker to deactivate the filling process).

ERROR MESSAGE/MEANING

Operation mode
Normal operation
(Filling level below the probe
response height)
Alarm Filling level reaches probe
response height when filling
Alarm acknowledged (with button)
Failure of the auxiliary energy
Disruption of the line between the
indicator and the probe or of the
PTC thermistor
Short circuit of the line between the
indicator and the probe or of the
PTC thermistor
The relay outputs Alarm 1 and Alarm 2 are not monitored, i.e. a line disconnection or a short
circuit to the connected signalling and control devices is not recognised and indicated by the
indicator.
*1) In case of disruption: flashes 2 times every 5 seconds. After removal of the disruption,
the unit returns to the operating state "normal operation" after a short time.
*2) In the event of a short circuit: flashes 4 times every 5 seconds. After the short-circuit has
been removed and acknowledged by pressing the Test button, the unit returns to the
"normal operation" mode after a short time.
