Indicator type BC-1-4 - Sectional View
Connection of the Outputs and the Potential-Free Relay Contacts on the Indicator
The indicator has 3 potential-free relay contacts.
The outputs Alarm 1 and Alarm 2 are intended for the actuation of external alarm units (for
the connection of the signalling or control devices of the overfill sensor).
The output Betrieb [Operation] is intended for connection of an external operation indicator
(lamp).
The outputs Alarm 1 and Alarm 2 are not monitored, i.e. a line disconnection or a short
circuit to the connected signalling or control devices is not recognised and indicated by the
measuring transducer.
Therefore, either the signalling and control devices must be switched in such a way that a line
disconnection is signalled (static current principle) or a functional control of the overfill sensor
(including the connected signalling and control devices with actuator) must be carried out
before each filling.
This can be done by pushing the Prüfen [Test] button at the measuring transducer – this
leads to an alarm signal, and possibly connected signalling and control devices are switched.
After release of the Prüfen [Test] button, the alarm signal goes out.
The indicated test does not replace the required annual test (see paragraph
MAINTENANCE).

If one of the Operation, Alarm1 and Alarm2 connections is operated with SELV
(safety extra-low voltage) or PELV (protective low voltage) electrical circuits, it is also
the case that the others can only be operated with SELV and/or PELV or not
connected.
