Obstacle detection system (anti crushing)
The 909 control board is equipped with obstacle detection and the sensitivity can be adjusted by using the trimmer marked
SENS . This trimmer controls the level set that the gate will stop and reverse away if an obstacle is met during the normal run
time. Turning the trimmer further to the – makes it more sensitive to obstacles. Turning the trimmer further to the + makes it
less sensitive to obstacles. Turning the SENS trimmer completely to the + will disable this feature and the system will then rely
solely on the POWER trimmer. The second level of safety is the power sent to the motors set by the trimmer marked POWER
Turning this trimmer further to the – sends less power to the motors and turning the trimmer further to the + sends more power
to the motors. During the slowing down period the system only uses the POWER setting trimmer.

10 centimetres and it will then auto re-close after 30 seconds. If the obstacle remains, the system will try again 3 times and
then finally remain open. If the automatic closing is set, it will follow the set time before closing again. If the gate is at the
deceleration stage
(usually around 500mm before fully open or close) it will stop and not move again until given another command. If the
gate meets an obstacle while closing, it will reverse completely and it will auto re-close after 30 seconds. If the automatic
closing is set, it will follow the set time. If it is at the deceleration stage, it will stop and not move again until given another
command.
Full obstacle detection control throughout the full cycle of opening and closing (including the slowdown stage) can be achieved
by using a safety edge, (Rib edge) through the ‘F. AP with, SW2-2 OFF = NC safety edge, ON = 8K2 safety edge. Input on
terminal 9. The wired safety edge system can be used with normally closed circuits and resistor 8k2 ohm circuits. Safety edges
are used on gates in all areas where a specific risk of trapping may occur, especially where there is less than a 50cm gap
behind a gate when fully open. Resistor 8k2 ohm circuits are used where CAT3 safety edges are needed. The 8k2 ohm circuit
when installed correctly will always fail to safe if damaged shorted or open circuited.
