As well as reducing the speed of the manoeuvre, the deceleration function also reduces motor torque by 70%.
For systems requiring elevated torque, this decrease may cause the motor to stop immediately.
Deceleration function in sliding mode
At the end of an opening or closing manoeuvre due to the expiration of the Working Time the system enters a deceleration stage which lasts
up to a maximum of half the Working Time, until the limit switches are reached.
If the manoeuvre stops due to the triggering of the limit switches, the deceleration stage has not taken place. In this case it is necessary to
adjust the Working Time so that the deceleration stage starts 80-50 cm. before the limit switches are triggered.
Deceleration function in overhead mode
At the end of a closing manoeuvre due to the expiration of the Working Time the system enters a deceleration stage which lasts _ of the
Working Time.
If the manoeuvre stops due to the triggering of the FCC limit switch, the duration of the deceleration stage will be proportional to the Work-
ing Time. (for proper operation of the deceleration feature we recommend the installation of the limit switches).
During the opening manoeuvre, a gradual stop replaces the deceleration feature.
Switch 9:
On
= Brake
At the end of the movement a motor brake procedure is electrically performed in order to stop the gate as rapidly as possible.
Switch 10:
On
= Phototest
This function controls photocell efficiency at the beginning of each manoeuvre. See the “PHOTOTEST” chapter.

OVERHEAD GARAGE DOOR
SLIDING GATE
The basic difference between the Sliding gate and Overhead door modes concerns the deceleration function (dip-switch n°8). When the
latter is active in the Overhead door mode, deceleration starts as soon as the closing limit switch is reached, while in the sliding gate mode
deceleration starts before the limit switch is reached. In both cases the deceleration time is proportional to the Working Time (TL).
