Start-Up - GOK BC-2 Instrucciones Para El Montaje Y El Funcionamiento

The supply voltage for the external acknowledgement button (terminal 9) or for the
external test button (terminal 10) is applied to terminal 11..
The housing of the display unit is suitable for wall mounting and is connected to
the main supply. The display unit must be operated with the housing cover closed.
After the connection of the terminals, screw on the front panel again!
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.

START-UP

The display unit must be connected to an overcurrent protective equipment
(OCP) which is easy to reach.
The display unit may only be operated with a closed housing cover.
Settings on the indicator are not required.
The start-up of the BC-2 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 20s, this alarm message disappears and only the green LED 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 Test button on the indicator triggers an alarm. In the process, an alarm
indication as described above must be emitted.
The probe must not be immersed in the operating medium during this test.
Remove probe.

Danger to life due to electric shock!
Electric shock from touching live parts.
Disconnect the power.
Only touch the probe when the display unit is not supplied with
power.
Only place under tension after ending all work.
