6.2 Torque adjusting of the motor.
The control unit Is furnished with a trimmer for adjusting the torque supplied to the motor, in order to limit the force of gate against some obstacles
that might get in the way during motion (for ex. poor/fair functioning of photocells).

For regulating the torque applied by the motor, proceed as follows:
•
Act on trimmer regulation to set the torque desired, keeping in mind that the trimmer is at the minimum level when loca-
ted in the extreme counter-clockwise direction and at the maximum level when located in the extreme clockwise
direction.
•
Start up the motor and check the torque.
•
If the regulation is not adecuate, stop the movement and fit the trimmer again, than start up the motor again.
•
Is advisable to check the torque before regulating the gate movement.

The automatiic re-closing function is an operation that enables the automatic re-closing of gate when the pause time selec-
ted by the “A. RECL. TIME” is over.
The enabling or disabling of function is given from the same trimmer, that is:
•
Defining the whole trimmer for extreme counter-clockwise (minimum), the automatic re-closing is disabled.
•
Defining the whole trimmer for clockwise, on introduct the automatic re-closing.
NOTA: The successive learning can now be executed also with the memorized tranmitter. The operative modalities are
reported here following.
7. Funzioni selezionabili tramite DIP-SWITCH.
It is important to change the configuration of the dip-
switch only with power down.
7.2 Water hammer.
If the automation mechanism provides for an electric lock and this is enabled, when the gate is closed, it is advisable for the motor to operate in clo-
sing state for a shortly period before starting the opening one. This function makes it possible to open the electric lock in any case, even in bad wea-
ther conditions (such as in the event of ice).
Water hammer is active for opening stage and the electrical lock is controlled through the control unit. The
default cycle provides for a minimum water hammer during the opening phase and for no water hammer
during the closing one, which may be modified as described in paragraph 8.1.
It is possible to change the way the control unit responds to commands given by the remote control or step-by-step key (pulse button):
Step-by-step order may be given by a special input (see pulse switch on terminal block), or by pushing the first key of a memorised transmitter (see
section 5 learning transmitter).
7.1 Step-by-step function.

Water hammer is disable but the electrical lock is still active ( this is very usefull when a magnetic lock
is present).
When an obstacle interfers with the beam emitted by the transmitter and receiver photocells, the sames modify control unit condition as follows:
7.3 Safety and protection photocells.
A) during the gate opening cycle: if photocells detects an obstacle, the gate motion continues
B) during the gate closing cycle: if photocells detects an obstacle, the central unit blocks and invertes
the direction of gate until it is totally opened.

A) during the gate opening cycle : if photocells detects an obstacle, the central unit stops the gate. When
the obstacle is removed, the door OPEN cycle resumes until the door is open fully.
B) during the gate closing cycle: if photocells detects an obstacle, the central unit stops the gate. When
the obstacle is removed, the door OPEN cycle resumes until the door is open fully.
