Obstacle detection system
The 207 board is equipped with obstacle detection and the sensitivity can be adjusted by using the trimmer marked
AMP
.
The working speed can be adjusted using the trimmer marked
VELOC
and the slowing down speed using the trimmer
marked
RALL.
When the system is in operation and
the gate meets an obstacle during the opening cycle, it will reverse the stroke for about
5 centimetres and it will then auto re-close after 30 seconds. 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
‘COSTA’
input on J1 terminal 8. 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.
Battery charging
The board is able to work with or without a battery. If the system is operating with a battery, the board itself will recharge the
battery. About 24 hours are required to completely recharge the battery. The board draws, with a 7 Ah battery, in the normal
working 140 mA equal to 50 hours and in stand-by 38 mA equal to 84 hours.

Safety advises.
In order to prevent any kind of accident, only qualified and professional people will be allowed to operate, install, repair or
adjust the control panel and only after all the necessary safety rules have been respected, as well as power supply cut off
(including the back up batteries). If the control panel will be used for any other purpose (not reported in the user manual),
will be not responsible for any kind of damage or accident caused to people, animals or things. This product is not suitable to
be installed in an explosive atmosphere. Keep this booklet together with the rest of the technical information regarding the
installation in a suitable place and available to professional installer who will need to do future maintenance.
