6 MAINTENANCE AND ASSISTANCE
6.1 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
Main Power supply LED off Tx
and/or Rx
Power Supply 19 V~ or 24V
missing
Check out the Primary and Secondary
power supply of the Transformer
F2 Fuse of Power Supply Circuit
broken
Change the fuse
Connections broken
Ad just the connections
Power Supply circuit broken
Change the Electronic board
Fault Led OFF
Supply Voltage too high or too
low
Check the battery voltage and the
power supply circuit
Tx Low Frequency Oscillator
Change the Tx Electronic board
Tx MW Oscillator Fault
Change the MW Oscillator
Tx or Rx failures
Change the Electronic board (Tx or
Rx)
Alarm Led OFF
Movement or obstacles in the
protected field
Check out that the protected field is
free from obstacles and free from
objects and/or people moving.
Barrier not properly aligned
Re do the alignment procedure as
described in points: a,b,c,d,e,f,g,h,I,j of
chapter 4.1.2
Wrong channel selections
Do again the Channel acknowledge
procedure as described in point j of
chapter 4.1.2
High AGC Voltage
Barrier not properly aligned
Re do the alignment procedure as
described in points: a,b,c,d,e,f,g,h,I,j of
chapter 4.1.2
Obstacles within the MW beam
Remove obstacles
Too low signal transmitted
Check the transmitter
Rx circuit fault
Change the Rx circuit
Rx MW detector fault
Change the RX MW detector
Tamper Led OFF
Micro switch open
Check the micro switch position
Tilt bulb in wrong position
Check the position of the tilt bulb
6.2 Maintenance kits
The
Maintenance Kits
are composed by circuits equipped with microwave cavities, always for
220 m. range, their substitution is very easy: Unlock the fixing screws and install the new
circuits and cavities.
The circuit and cavity substitution on both
transmitter and receiver heads doesn’t
changes the heads alignment, and so no new mechanical alignment is required, but it is
necessary the acquisition of the field value and of the channel number see chapter 4.1.2
