Operation
Notice for Switzerland
For shut-off devices and booster pumps in Switzerland, the following must be observed:
These devices are, depending on the plant, very different and may not be specified
universally. In particular, the plant owner must install a suitable shut-off device which is
automatically controlled by the special filling protector (e.g. solenoid valve). This happens
within the scope of the proper approval procedure and with the approval of the responsible
cantonal authority.
In case of storage plants with several containers and with a common filler line, a single
automatically controlled shut-off device may be sufficient if each tank has at least one manual
slide and the filling levels of all containers are the same.
In case of plants with their own stationary booster pumps, the special filling protection must
shut off the booster pumps when reaching the maximum permissible filling level which is
determined by the effective volume according to section 20 VWF – when operating the sensor
at the latest and prior to closing the automatic shut-off device.
Connection of External Buttons for Alarm Deactivation
No extraneous voltage may be applied to terminal 9 + 10 or to terminal 13 + 14!
The indicator has an input for an external acknowledgement button
(Terminals 9 + 10). The function corresponds with the Alarmton Quittieren [Reset Alarm
Sound] button integrated into the indicator which can reset (deactivate) the acoustic alarm as
well as the output Alarm 2 in case of an alarm.
The indicator has an input for an external test key (Terminals 13 + 14). The function
corresponds to the Prüfen [Test] button in the indicator which controls the alarm function in
the monitoring mode: Display red LED Alarm and buzzer tone.
After the connection of the terminals, screw on the front panel again!

START-UP

Settings on the indicator are not required.
The start-up of the BC-1 overfill sensor is carried out after assembly is completed by applying
the supply voltage. A start-up alarm is emitted first. It is indicated via the red LED Alarm
optically and via a buzzer acoustically; in this case, the Alarm 1 and Alarm 2 relay outputs
together with possibly connected external signalling or control devices (e.g. solenoid valve,
signal horn or lamp) are switched.
After about 20 s, this alarm message disappears and only the green LED Betrieb
[Operation] lights up – the operation relay output is switched on, so that a possibly connected
external signal light goes on as well.
The Alarm 1 and Alarm 2 relay outputs are deactivated.
After that, a functional check with all components of the overfill sensor (including any
connected signalling and control devices) should be performed.
The operating manuals of the connected appliances must be respected.
Pressing the Prüfen [Test] button on the indicator triggers an alarm. In the process, an alarm
indication as described above must be emitted.
