4.3 SETTING THE CHAIN MOVEMENT
This procedure must be carried out ONLY by the installer and ONLY
during the setting up of the system. The movement can be effectuated
in particular situations in which it is not possible to lift the chain in
automatic mode.
WARNING: With the trimmer in disabled position ( flashing light turned on), the anti-squeezing security is excluded.
4.4 REGULATION OF THE ANTI-SQUEEZING SECURITY
This procedure must be carried out ONLY by the installer and ONLY
during the setting up of the system. The movement can be effectuated
in particular situations in which it is not possible to move the chain to the
lifted position in automatic mode.
4.5 REGULATION OF THE AUTOMATIC RE-CLOSURE TIME
This procedure must be carried out ONLY by the installer and ONLY
during the setting up of the system. The movement can be effectuated
in particular situations in which it is not possible to move the chain to the
lifted position in automatic mode.
With the chain in movement, check
the sensibility of the intervention of
the antisqueezing security and check
that there is a regular functioning of
the chain.
SW1 POSITION
MAN AUT
Check that the functioning is regular and
that the sensibility is setted in a correct way,
increase lightly the trimmer to balance the
frictions wich can vary with the time and the
temperature.
Turn
the
trimmer
in
anti-clockwise sense to
decrease the force of the
motors.
It is possible to turn the
trimmer in clockwise sense
to increase the force of the
motors.
If it is too low
If it is too high

Turn the A. RECL. TIME trimmer
in clockwise sense.
In this way, the automatic re-
closure time is increased.
Turn the A. RECL. TIME trimmer
anticlockwise sense.
In this way the automatic re-
closure time is reduced.
The time is too brief
By turning the A. RECL. TIME trimmer completely in
anticlockwise sense in band 1. The re-closure is controlled
by the intervention of the photocells (after a few seconds
from the photocell contact release, the chain rises).
Turn the A. RECL. TIME trimmer
completely in clockwise sense.
In this way you can disable
automatic re-closure.

When the chain reaches the desired lower
position, re-press the BLUE button.
The chain stops.
Press the BLUE button. The chain begins
to lower.
Check the wiring of the motor. Repeat the test.
Check if the chain is into the complete lifted position.
Check if SW1 is in the AUTO position and repeat the test.
Re-press the BLUE button.
Press the step by step button (terminal
blocks 5 and 11). The chain rises to the
upper position.
During the memorization of the course and for the successive 2
complete cycles of moving (lowering-raising) avoid interventions on
the inputs of stops and photocells, avoid also the verify of the sense,
because the central in these 2 first movings acquires the parameters
for a correct functioning.
Press the step by step button (terminal
blocks 5 and 11). The chain begins to
lower.
The rising and lowering are stored.
If the chain inverts the movement, bring it back to the upper position
with the SW1 in MAN position. Once the chain is lifted, move back
the SW1 to AUT.
If the chain inverts the movement, bring it back to the upper position
with the SW1 in MAN position. Once the chain is lifted, move back
the SW1 to AUT.
To re-program the rising and lowering repeat this procedure
