Operation; Function Check; Error Message/Meaning - GOK BC-1 Notice De Montage Et De Service

OPERATION

The indicator must indicate the monitoring mode constantly via the green LED Betrieb
[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. With the Alarmton Quittieren [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 to monitoring mode again.
Operation includes MAINTENANCE.
In the case of signalling and control devices being connected to Alarm 1 and Alarm 2, a
functional test has to be carried out by pressing the test button.

FUNCTION CHECK

By pressing the Prüfen [Test] button, the alarm function in monitoring mode may be checked:
Display red LED Alarm and buzzer tone. After the button is released, the alarm indication
disappears.
