impulse while the gate is still moving will stop the gate. A third impulse will cause the gate to reverse
its direction of travel, i.e. the action is START - STOP - REVERSE.
CONDIMINIUM MODE (FEATURE 4- 2) - Any trigger will cause a gate, which is closed or closing to
open or re-open. If not already active, the auto-close will automatically be turned on when
condominium mode is selected. It is only the auto-close signal, which can close a gate in condo-
minium mode. If a trigger impulse is given while the gate is open the auto-close time is reset to its
preset value.
PIRAC MODE (FEATURE 4-3) - An acronym for Passive Infra Red Auto Close, this mode operates
similarly to condominium mode but instead of waiting for the auto-close timer to close the gate, it
will close as soon as an object that has passed through the gate clears the infrared beam. If the
beam is not broken the gate will get to its fully open position and close after the preset auto-close
time. This feature will only operate if infrared safety beams or if an inductive loop is fitted (IRB
terminal).
REVERSING MODE (FEATURE 4-4)- This mode is similar to standard mode but instead of
stopping a gate when it is in motion, a trigger will cause the gate to reverse its direction of travel. It is
thus impossible to leave a gate stationary in a partly open position. The only two normally stable
states are fully open or fully closed. If the auto-close is ON then the gate will always tend towards
being closed.
Pedestrian Auto-Close Time
A separate auto-closer timer exists for the pedestrian opening. The time can be set from 1 to 255 seconds
but cannot be turned off completely. The default time is 5 seconds.
Collision Sensitivity
If the gate is obstructed the internal collision circuitry will activate. When the gate is opening, and it is
obstructed the gate will stop. Master and slave gates operate independently of each other while opening
i.e. a collision to the master gate will not stop the slave gate from opening fully. During closing however, an
obstruction to either master or slave gate will cause both gates to immediately stop and reverse direction.
There is a counter (FEATURE 12-COUNT) that monitors the number of collisions. If the collision count is
reached before both gates reach the fully closed position all trigger signals are inhibited for a 1 minute
period. The STATUS LED flashing 4 times indicates this condition. After the 1 minute period. triggers will
again become active, (with the exception of auto-close). The fault indication will continue to flash
indefinitely after the 1 minute period but will clear after the 1 minute period is a valid trigger is given. The
collision counter resets to zero after the 1 minute delay, or the processor is reset. (e.g. By removing all
power from the controller.)
Courtesy (Pillar) Light:
The pillar circuit has multiple functions:
• It operates as a courtesy light and switches on for a timed period. (The factory default is 2
minutes) (set by FEATURE 6-COUNT) every time the gate triggers.
• It can be turned on for the preset timed period, by the application of a short impulse between the
SET terminal and COM.
• It can be turned ON permanently by application of an impulse longer than 3 seconds on SET and
COM terminals. A short impulse thereafter will switch the lights off. The gate will not trigger open
when using the SET trigger. The fact that the pillar light is ON permanently is indicated by the
STATUS LED flashing once every 2 seconds.
(FEATURE 5 - COUNT)
(FEATURE 7-1 to 7-3) (The factory default is 7-1)
