4.3 PROGRAMMING THE CHAIN RACE
This procedure must be carried out ONLY by the installer and ONLY during the setting up of the system.
For correct programming, before making changes, always return the chain to the high position (see paragraph 4.2).
A
SW1 POSITION
MAN
AUT
Press the BLUE button. The chain begins to lower.
When the chain reaches the desired lower position, re-press the BLUE button. The chain
stops.
Press the step by step button (terminal blocks 5 and 11). The chain rises to the upper
position.
During the memorization of the race and for the next 2 complete cycles of moving
(lowering+raising) avoid interventions on stop and photocells.
Avoid also the intervention of the current sensor, because the card in these 2 first
movements acquires the parameters for a proper functioning.
Press the step by step button (terminal blocks 5 and 11). The chain lowers completely.
4.4 ADJUSTMENT OF THE CURRENT SENSOR
This procedure must be carried out ONLY by the installer and ONLY during the setting up of the system.
The movement can be performed 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 completely raise

If the chain inverts the movement, bring it back to the upper position (SW1 to MAN and
maintain pushed the YELLOW button).
Once the chain is raised, move back the SW1 to AUT and restart from point A.
NO
If the chain inverts the movement, bring it back to the upper position (SW1 to MAN and
maintain pushed the YELLOW button).
Once the chain is lifted, move back the SW1 to AUT and restart from point A
Sensitivity too high or
not constant operation
It is possible to turn the TORQUE STOP trimmer in
clockwise sense to increase the force of the motors.
Repeat the
sensitivity check
TRIMMER 1 - Raising managed by photocells
TRIMMER 2-> 3 - automatic rise waiting time from 3 s to 180 s
TRIMMER 3 - automatic raising disabled
Turn the AUT. CLOSE TIME trimmer in clockwise sense.
In this way, the automatic chain raising pause time
is increased.
Turn the AUT. CLOSE TIME trimmer anticlockwise

In this way, the automatic chain raising pause time
is reduced.

To re-program the rising and lowering repeat this procedure from point A.
Check that the functioning is regular and that the sensitivity
is setted in a correct way.
Increase lightly the trimmer to balance the frictions which
can vary with the time and the temperature.
By turning the AUT. CLOSE TIME trimmer completely in anticlockwise
sense (1) the chain raising is managed by the photocells (after a
few seconds from the photocell contact release, the chain rises).
