5. MAINTENANCE AND ASSISTANCE
5.1 Troubleshooting
In case of false alarm, check the parameters recorded during the
Installation
phase (on
attached
Test Sheet
), if there are divergences with permitted limits check again the related
points in chapter "Adjustment and Testing (4)"
Defect
Possible Cause
Possible Solution
Power too high or too low
Check the power supply voltage
Temperature too high or too low
Check the temperature of the barrier
Tx Oscillator Fault
Change the Oscillator
Fault Led ON
Tx or Rx failures
Change the Electronic board
Movement or obstacles in the
protected field
Check out that the protected field is
free from obstacles and free from
objects and/or person moving.
Barrier not properly aligned
Re do the alignment procedure as
described in points: a,b,c,d,e,f,g,h,i of
charter 4.1.2
Alarm Led ON
Wrong channel selections
Do again the Channel acknowledge
procedure as described in point b, j of
charter 4.1.2
Barrier not properly aligned
Re do the alignment procedure as
described in points: a,b,c,d,e,f,g,h,i,j
of charter 4.1.2
obstacles in the protected field
Remove obstacles
Too low signal transmitted
Check the transmitter
Rx circuit fault
Change the Rx circuit
High AGC Voltage
Rx MW part fault
Change the RX MW part
Micro switch open
Check the micro switch position
Tamper Led ON
Tilt bulb in wrong position
Check the position of the tilt bulb
(Vertical)
BF Oscillator Fault
Change the TX circuit
Fault Led ON only on TX circuit
MW oscillator Fault
Change the MW part
5.2 Maintenance kits
The
Maintenance Kits
are composed by circuits equipped with microwave cavities, their
substitution is very easy:
The circuit and cavity substitution on boot transmitter and receiver heads doesn’t
changes the heads alignment, and so no new alignment is required
