3.3.2
Checking of the sensors operability
3.3.2.1
In order to check remotely the sensors operability, apply the voltage of 5 … 30 V
to the circuit “Remote Control” of the transceiver unit from the control panel
respectively to the sensor power supply “–“. The sensor should trigger.
3.3.3
Checking of the sensors appearance.
3.3.3.1
Check the integrity of the transceiver unit, pay attention to the absence of dents,
corrosion, damage of coating, cracks. In case of presence of corrosion signs
remove if with a rag with kerosene and put an anti-corrosion agent.
3.3.3.2
Check the transceiver unit for the absence of dust, dirt, snow and ice from the side
of transmitting and receiving and clean them if necessary.
3.3.3.3
Check the tightening of fixing parts fixing the sensor units to the pole or protected
surface; tighten the fixing parts if necessary.
3.3.3.4
Check the state of connection cables from the sensor unit to the junction box.
3.3.4
Checking of the protected sector state.
3.3.4.1
Check the protected sector for the absence of foreign objects causing false alarms.
3.3.4.2
Check the height of grass cover during seasonal works. In case grass exceeds the
allowed height (see item. 1.2.2.1), remove it.
3.3.4.3
The changing of height of snow cover on the protected site may reduce the input
signal on the transceiver causing false alarms. Remove the snow or change the
height of installation of the transceiver on the pole.
After changing the height of installation of the transceiver, configure the
triggering threshold according to the procedures given in the present User
Manual.
