1.
Press and hold down the T1 key on the control unit to start the motor
2.
After holding down the T1 key for 5 seconds, start to memorize the time of the manoeuvre
5s
3.
When you release the T1 key the motor will stop and the new working time will be
programmed
Note: If you wish to modify the working time, repeat the above procedure starting from step 1
The working time should be programmed to last a few seconds more than is strictly necessary for the completion of the manoeuvre.

Programming the working time
Example
3) Programming
The control unit allows you to program the parameters and select the functions that are described below.
3.1) Programming the working time
The motor’s working time can be programmed from a minimum of 5
seconds to a maximum of 120 seconds (factory setting or after total
memory erasure). Once the working time has been programmed,
each command will activate the motor for the programmed length of
time. To proceed with the programming process, follow the steps in
the table below.
Switch 1
Off
= SECURITY DEVICES input as “STOP” (short reversal and stopping of manoeuvre)
On
= SECURITY DEVICES input as “PHOTOCELL” (causes reversal during closing manoeuvre)
Switch 2
Off
= STEP-BY-STEP input for “step-by-step” operation
On
= STEP-BY-STEP input for “open” operation
Switch 3-4
Off
Off
= SECURITY DEVICES input with NC contact
On
On
= SECURITY DEVICES input with NO contact
Off
On
= SECURITY DEVICES input with constant resistance contact 8.2K
Ω
On Off
= not allowed
3.2) Programmable functions
The control unit features 3 inputs that perform command and secu-
rity functions. A four-contact dip-switch allows certain functions to
be personalised in order to make the system more suitable to users’
requirements.
Warning: Certain programmable functions are linked to
security features; evaluate them carefully also based on the
required security level.
Switch 1:
off
= the SECURITY DEVICES input operates as a STOP input: without an enable signal, the movement is prevented and if the motor
is already running a brief reversal is activated.
on
= the SECURITY DEVICES input operates as a PHOTOCELL input: in the absence of an enable signal only the opening manoeuvre
can be carried out. If the enable signal fails during the closing manoeuvre, a reversal and opening manoeuvre is carried out
Switch 2:
off
= the STEP-BY-STEP input operates in “step-by-step” mode: each command activates the open-stop-close-stop sequence.
on
= the STEP-BY-STEP input operates in “open” mode: each command activates the open-stop-open-stop sequence.
This setting is useful if the input is used in conjunction with the CLOSE input and a selector switch enabling the independent
activation of the opening and closing manoeuvres.
Switch 3-4:
Used to select the type of contact that must exist between the common input and the SECURITY DEVICES input to enable the manoeuvre.
off-off
= security devices with NC contacts
on-on
= security devices with NO contacts
off-on
= security devices with constant resistance 8.2 K
Ω
on-off
= not allowed
3.3) Description of functions
Here is a brief description of the control unit’s functions and behaviour based on the programmed settings.
