12 - DETECTION OF OBSTACLES
(AMPEROMETRIC SENSOR / SAFETY
RIBBONS)
The presence of an obstacle that prevents the movement of the
gate can be detected in several ways:

1. Amperometric sensor

2. Safety ribbons
m
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 22.3)
If you want to disable this feature set the value to

12.2 - 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 active ribbons during opening between the terminals
S7 and S9.
Enable the operation of the ribbons through the parameter
:
COS1
• If you set the operation of the ribbon is detected only
AP
during opening and the gate reverses the movement for 2.5
seconds
• If you set the operation of ribbon is detected during
APCH
the opening and closing: when opening the gate reverses the
movement for 2.5 seconds, while when closing the gate is
stopped
Connect the active ribbons when closing between terminals S8
and S9.
Enable the operation of the ribbons through the parameter COS2:
• If you set the operation of the ribbon is detected only
CH
during closing and the gate reverses the movement for 2.5
seconds
• If you set the operation of the ribbon is detected
APCH
during closing and opening: when closing the gate reverses the
movement for 2.5 seconds, while when opening the gate is
stopped

Connect the power supply of the optical ribbons following the
instructions described in chapter 11.1
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.
