Connection of the Outputs – 2 Potential-Free Relay Contacts on the Indicator
The indicator has 2 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 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 indicator.
Therefore, either the signalling and control devices must be switched in such a way that a line
disconnection is signalled (static current principle). If this is not possible, a notice must be
placed in the close distance of the indicator that a FUNCTIONAL CHECK of the overfill sensor
(including the connected signalling and control devices with actuator) must be carried out
before each filling. This FUNCTIONAL CHECK can be done by pushing the Test button on
the display unit – this leads to an alarm signal, and possibly connected signalling and control
devices are switched. After release of the Test button (approx. 10 seconds after pushing), 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 1A for equipment connected to the potential-free
relay contacts. The permitted Line cross-section is 1.5 – 2.5mm².

Connection of External Buttons for Alarm Deactivation
No extraneous voltage may be applied to terminal 9 + 11 or to terminal 10 + 11!
The indicator has an input for an external acknowledgement button (Terminal 9). The function
corresponds with the 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 (Terminal 10). The function corresponds to
the Test button in the indicator which controls the alarm function in the monitoring mode:
Display red LED Alarm and buzzer tone.
