CONDOMINIUM MODE
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
condominium mode. If a trigger impulse is given while the gate is open the auto-close time is
reset to its preset value.
PIRAC MODE
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 immediately when auto-
close is turned OFF.
If the Auto-close feature is turned ON the gate will open and remain open for the set auto-close
time, and then close. The gate will however close as soon as an object has passed through and
cleared the beam, regardless of the Auto-close time.
REVERSING MODE
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-close 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. During closing however, an obstruction to the gate will cause it to immedi-
ately stop and reverse direction. There is a counter (FEATURE 12-COUNT) that monitors the number of
collisions. If the collision count is reached before the gate reaches the fully closed position all trigger
signals are inhibited for a 1-minute period. The STATUS LED flashing 4 times per swecond indicates this
condition. After the one-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 if a valid trigger is given. The collision counter resets to zero after the 1 minute delay, or if
the processor is reset (e.g. By removing all power from the controller).
Courtesy (Pillar) Light:
The pillar light circuit has multiple functions:
! It operates as a courtesy light and switches on for a timed period (The factory default time 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.
! When the PED input is triggered the pillar light flashes for an adjustable (1 to 255 seconds) pre-
flash time (FEATURE 11-COUNT) before the pedestrian gate opens. (Default pre-flash time is
(FEATURE 4-2) - Any trigger will cause a gate, which is closed or closing
(FEATURE 4-3) - An acronym for Passive Infra Red Auto Close, this mode operates
(FEATURE 4-4)- This mode is similar to standard mode but instead of
(FEATURE 5-COUNT)
(FEATURE 7-1 to 7-3) (The factory default is 7-1)
