(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).
No other appliances – particularly no safety-relevant appliances – may be
connected to the same overcurrent protective equipment as the appliance.
Do not exceed the maximum input current of 1 A for equipment connected to the potential-
free relay contacts.

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.

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
