Menu 6 - IR beams
PIRAC
The
Passive-Infrared Autoclose
feature allows the gate to close
automatically, as soon as a vehicle or pedestrian has passed through the
closing beam. This security feature ensures that the gate stays open for the
minimum amount of time possible.
If the
Autoclose
feature has been enabled, the system will react in the
following way:
When the gate is triggered to open and nothing moves through or interrupts
the closing beam, the gate will open fully and stay open for the period of
time determined by the
Autoclose
timer
However, if the closing beam is interrupted at any stage, while the gate is
opening or open, the gate will close immediately after the closing beam is
cleared
If the
Autoclose
feature has
not
been enabled then the gate will
remain open indefinitely. To close the gate the closing beam must be
interrupted or the trigger button must be pressed.
Stop on open
If
PIRAC
is enabled, and a vehicle breaks the closing safety beam, the gate
will by default, continue to open. If the gate is required to stop at this point,
the
stop on open
function must be enabled. The stopping distance setting
then determines in centimetres how far the gate will run on after the beam has
been broken. The minimum setting is zero, which will cause the gate to stop
immediately after the closing beam has been broken. The maximum setting is
determined by the length of the gate.
PIRAC override
The
PIRAC
feature can be temporarily disabled in the following manner:
With the gate in the closed or partially closed position, press and hold the
trigger button. The gate will begin to open and then stop. Continue holding
the trigger button until the gate begins to open again
Release the trigger button
The gate is now in
PIRAC override
To re-enable the
PIRAC
feature press the trigger button briefly
The time taken for the gate to come to a stop is equal to the
Autoclose
override time
,
or a minimum of two seconds if the
Autoclose override
time
is
off
Crawl distance
Sets the final crawl distance in centimetres of travel of the gate when reaching
an endpoint. This can be set from 10 centimetres to 10 metres in 1 centimetre
steps.
Torque limit
Sets the maximum torque delivered by the motor. The maximum setting is a
value of 15, while the minimum is four. This is useful in cases where limited
push force is required.
