VR1: Sensitivity in detecting obstacles
The operator has an encoder to detect obstacles and
prevent collisions. Sensitivity in detection can be adjusted
using this potentiometer.
Turning the potentiometer clockwise decreases sensitivity;
turning it anti-clockwise increases it.
VR2: Braking time
The motor is used to brake at the end of the operation, thus
offsetting the inertia of the gate when braking.
Adjust the potentiometer to ensure proper braking.
Turning the potentiometer clockwise increases the force;
turning it anti-clockwise decreases it.
VR3: Soft-stop distance
Soft-stop adjustment, where the operator moves at slow
speed before reaching the stopper.
Turning the potentiometer clockwise increases the
distance; turning it anti-clockwise decreases it.
VR4: Operator force
Torque or force exerted by the operator during the
operation. To ensure safety for people, adjust the force at
the lowest value compatible with good operation of the
facility.
Turning the potentiometer clockwise increases the force;
turning it anti-clockwise decreases it.
Torque adjustment, respecting the maximum
closing forces set out in Standard EN12453:2000.
Make the readings as described in Standard EN
12445:2000.
