3.4. Diagnostic plug
For an optimum adjustment of the detector, please connect diagnostic device VEK FG2.
Diagnostic device VEK FG2 indicates all relevant data for initiation and service. It provides
information on the loop/detector system, so that we may then optimise the adjustments as
well as localise the cause for malfunctions. For further information, please refer to the
operating instructions of diagnostic device VEK FG2.
Warning
: please only plug in the diagnostic cable when the detector is idle !
3.5. LED-display
The green LED indicates that the detector channel is ready for operation and sends out
important hints regarding initiation of the detector (failure, adjustment, frequency output) via
flash signals. The red LED indicates activation of the relay output in dependence on the
availability condition of the loop.

3.6. Loop frequency output
After the detector has been readjusted, the loop frequency is indicated by flash signals of the
green LED. Approx. 1s after the successful readjustment, the output starts with the 10kHz-
position of the frequency value. The green LED of the detector channel will flash 1 time per
10kHz loop frequency. After a 1s break, the 1kHz-position will be indicated in the same way.
In case that the units digit has the valency '0', 10 flash signals will be emitted. The duration
of the flash signals of the 1kHz-position is a little shorter than the one of the 10kHz- position.
Example of a 57kHz loop frequency:
5x 10kHz
7x 1kHz
entspricht: 57kHz

If both channels are adjusted at the same time, the frequency of channel 1 is indicated
before channel 2.
