11. TROUBLESHOOTING GUIDE

List of possible troubles is given in Table 11.1.
Table 11.1

Trouble

Possible Cause

Repair

1. The receiving-
control device
constantly generates
an alarm.

1. Communication line is

broken.

Check the cable integrity
and the accuracy of its
connection. Restore the
communication line.

2. The protective device in

the PSU is blown.

Replace the protective
device.

3. The sensor alignment is

disturbed.

Align Tx and Rx antennas.

4. Tx is out of order.

Replace Tx.

5. Rx is out of order.

Replace Rx.

2. False alarms.

1. Moving branches in the

detection zone.

Inspect the protected sector
and remove interference
factors.

2. High grass in the

detection zone.

3. Snow blanket is above the

norm and reduces the
input signal.

4. Animals movement in the

detection zone.

5. The Rx thresholds are too

low.

Check the accuracy of the
Rx thresholds settings.

3. The sensor does

not generate
alarms when an
intruder crosses
the detection
zone.

1. Rx thresholds are too

high.

Check the accuracy of the
Rx thresholds settings.

2. The alignment is

disturbed.

Align Tx and Rx antennas.
