IMPORTANT:
• Do not connect auxiliary relays or other devices tot he 18 V DC output (terminals 11 – 12) to
avoid malfunctions of the control unit. Use separated power supply / transformers instead;
• do not connect switching feeders or similar apparatus close to the barrier that may be a
source of disturbance;

FR. obstacle detection sensitivity adjustment.
Note: by rotating the TRIMMER FR. clockwise the sensitivity of the gearmotor
to obstacles diminishes and therefore the thrust force increases; vice-versa, by
rotating it counter-clockwise, the sensitivity of the gearmotor to obstacles
increases and therefore the thrust force diminishes.
