Align the thresholds very attentively as «underrating» of the thresholds might provoke a
lot of false alarms; «overrating» of the thresholds might provoke failures in the sensor
operation.
Close the Rx cover when the alignment is finished.
It is recommended to test the sensor for 2-3 days after its alignment with the aim to detect
possible errors in mounting and alignment.
10. CHECK OF TECHNICAL STATE
10.1.
Check of sensor operation
10.1.1
. During the exploitation it is recommended to test the sensor operability transmitting the
remote control signal («RC») 1-3 times a day.
10.2.
Maintenance
10.2.1.
The sensor maintenance should be conducted by people, who underwent special safety
trainings.
10.2.2.
During the sensor exploitation it is necessary to conduct check and preventive works.
10.2.3.
Every month carry out visual examination of the sensor units and the protected sector.
It is necessary to check:
-
the absence of dust, dirt, snow and ice from the side of Tx signal transmission and Rx
signal reception; clean the units if necessary;
-
the absence of foreign objects in the protected sector.
10.2.4
. Every quarter:
-
carry out all monthly works;
-
check the cables and cable connections.
10.2.5
. The grass height is controlled during seasonal works. If the grass height is over 0,3 m, the
grass should be mown down.
10.2.6.
If the snow height changes, false alarms can be generated because of the signal reduction at
the Rx input. In this case it is necessary to remove the snow or to change the height of Tx and
Rx antennas.
After the height of the antennas is changed, they should be aligned. The thresholds should be
aligned as described above.
