Installation Instruction
Modification of system(s)
It is possible to modify the installed systems on the GX-850M ver. IV. The following modifications are pos-
sible:
•
Reactivate passive sensors
•
Replace a malfunctioning sensor
•
Add an extra sensor
When the GX-850M ver. IV cannot communicate with a sensor, the GX-850M ver. IV reports the error: "Errors
detected!". The GX-850M ver. IV does not rely on malfunctioning sensors, and therefore the GX-850M ver. IV
makes the sensor passive. The passive sensor is no longer used for ice and snow detection - not even after a
power cycle.
If the malfunctioning is caused by problems with the wiring, the failure can be fixed, and the
sensor can be reactivated.
If the malfunctioning is caused by an error prone sensor, the error can be corrected by replacing
the error prone sensor with a new sensor.
It is not possible to delete a passive sensor in a system. Passive sensors will remain in the
systems until they are replaced with new sensors. The only way to delete a passive sensor (other
than replacing it), is to make a Master Reset and reinstall the GX-850M ver. IV (please refer to
chapter: General use).
Reactivate passive sensors:
The given example is for a ground system.
From the installer menu select Change system.
Press
to activate Change system.
The system is searching for connected sensors.
If any passive sensors are found, they are reactivated. Message is
shown for 3 seconds.
If no new sensors are found, it is reported to the user. Message is
shown for 3 seconds.
