12 - DETECTION OF OBSTACLES
(AMPEROMETRIC SENSOR, ENCODER,

SAFETY RIBBONS)

The presence of an obstacle that prevents the movement of the
door can be detected in several ways:

1. Amperometric sensor

2. Encoder

3. Safety ribbons
Regardless of the device that detected the obstacle, the reaction
of the unit depends on the value set for the parameter
obstacles during opening and
• If the value is , the port is simply stopped
0.0"
• If the value ranges between
the movement for the time set
• If the value is the door re-closes or re-opens completely.

Following detection of an obstacle during closure,
the door reopens and the behaviour of the power centre
depends on various parameters, with the following priority:
1. If the clock mode is active (
pause time for automatic closure is activated.
2. If the door is closed without withdrawing (
or if closure after the obstacle is manual (
counting of the pause time for automatic closure is NOT
activated and the door will start moving again after the next
start-up command is given
3. If closure after the obstacle is automatic (
the centre will behave according to the settings of the
parameter
12.1 - AMPEROMETRIC SENSOR
The control unit detects the presence of an obstacle when the
current on the motor exceeds the value set for the parameters
(opening) and
SEN.A SEN.C
The value of these parameters is pre-set during the self-learning
procedure of the travel (Chapter 25.3)
If you want to disable this feature set the value to
12.2 - ENCODER
The unit detects the presence of an obstacle when the encoder
indicates that the motor is turning at a speed lower than the set
one (Chapter 18).
The sensitivity of the encoder must be set via the
parameter: the higher the value, the more the unit will be
responsive to small drops in speed. If you do not want the
encoder to detect obstacles, set to
12.3 - SAFETY RIBBONS
The unit detects the presence of an obstacle when a safety ribbon
is pressed.
The unit has two inputs for the ribbons, which can be
independently enabled and associated with different types of
function.

Connect the power supply of the optical ribbons following the
instructions described in chapter 11.2
c. Ribbon with resistive rubber
Set the parameter
expected to measure an impedance equal to 8.2 kohms, and
an alarm is triggered if a lower impedance (pressed ribbon) or a
higher impedance (interrupted wire) are detected, therefore it
is not necessary to run the test before the movements.

WARNING: If you connect multiple ribbons to the same
terminal, the connection must be made in series, except in the
case of resistive ribbons which which must be connected in
parallel.
