FUNCTIONS DESCRIPTION
1. Four channel frequency selection
The beam pairs may be set at various frequency levels to
avoid crosstalk between units which are stacked, in-line, or
other configurations which have the potential of spill-over
transmission from one beam to another. Set the frequency
level as illustrated.
1) Linear protection
3) Double stacked linear protection
MAKE SURE TRANSMITTER AND RECEIVER OF
PAIR ARE SET AT SAME CHANNEL ! Paired TR/RE
will not set up unless set at the same channel.
2) Double stack protection
4) Perimeter protection
2. Beam power selection
4. Auto-gain lock function
5) Perimeter double stacked protection
This option allows field selection of the appropriate beam
intensity relative to the application. For distance significantly
less than the specified protection distance, the beam intensity
should be reduced to eliminate potential reflection problems.
For zones reaching maximum protection distance, the beam level
should be set to the highest level.
The use of a voltmeter for alignment is advised to ensure
highest level of stability.
•
Note : For interior applications where greater chance for
reflection occurs, the setting should be at LOW.
1) The auto-gain lock serves to standardise the responsiveness
and tolerance level of the units regardless of varying
distance in an installation.
The situations above have exactly the same tolerance and responsiveness
levels even though the distance are different.
