Initialization
To initialize the detector, activate a reed relay located near the internal response indicator with the
supplied magnet. A flashing response indicator signals initialization.
During the initialization, the working range of the electronics (RANGE), the compensation value, all
smoothing algorithms and diagnostics, and the staus are set to an initial value. All required thresholds
are calculated. At the same time a self-test is performed.
•
lnitialization with the magnet.
Place the magnet directly behind the response indicator to activate the Reed relay
(Black or red point = magnet).
As soon as the response indicator flashes, the compensation value is formed (ap-
proximately 30 sec.). Do not interfere with the measurement during this time.
When the initialization is completed, the response indicator turns off. If any proce-
dural error has been made, a new initialization can be started at any time with the
magnet.
•
Test alarm with test filter.
Place the test filter immediately in front of the detector and cover the entire
measurement window. When an alarm is triggered, the response indicator turns on
after approximately 10 seconds.
•
The commissioning is now completed.
