1. GENERAL SAFETY PRECAUTIONS
This installation manual is intended for professionally competent personnel only.
The installation, the power connections and the settings must be completed in conformity with Good
:orNing Methods and with the regulations in force.
Before installing the product, carefully read the instructions. Bad installation could be ha]ardous. The pacNaging
materials (plastic, polystyrene, etc.) should not be discarded in the environment or left within reach of children,
as these are a potential source of hazard.
Before beginning the installation checN that the product is in perfect condition.
'o not install the product in explosive areas and atmospheres the presence of Àammable gas or fumes represents a serious threat to safety.
The safety devices (photocells, sensitive edges, emergency stop, etc.) must be installed taNing into account
the provisions and the directives in force, Good :orNing Methods, the installation area, the functional logic of
the system and the forces developed by the automation.
Before maNing power connections, checN that the rating corresponds to that of the mains supply. A mul-
tipolar disconnection switch with a contact opening gap of at least 3 mm must be included in the mains
supply. ChecN that upstream of the electrical installation an adequate residual current circuit breaNer and an
overcurrent cut out are ¿tted.
When requested, connect the automation to an effective earthing system carried out as indicated by current
safety regulations.
During installation, maintenance and repair operations, cut off the power supply before opening the cover to
access the electrical parts.
To handle electronic parts, wear earthed antistatic conductive bracelets. The manufacturer of the moto-
risation declines all responsibility in the event of components which are not compatible with the safe and
correct operation of the product.
For repairs or replacements of products only original spare parts must be used.

4. CONNECTION OF POWER SUPPLY
Fix the control panel permanently. Pass the cables along from the lower side of the container.
Before connecting the power supply, maNe sure the plate data correspond to that of the mains power supply.
An omnipolar disconnection switch with minimum contact gaps of 3 mm must be included in the mains supply.
ChecN that upstream of the electrical installation there is an adequate residual current circuit breaNer and a
suitable overcurrent cutout.
Use a 3x1.5 mm FROR 450/750V type electric cable and connect to the terminals L (brown), N (blue),
(yellow/green) in the automation.
Secure the cable using a special cable clamp.
MaNe sure there are no sharp edges that may damage the power supply cable.
Connection to the mains power supply, in the section outside the automation, is made with independent channels
and separated from the connections to the control and safety devices.

1- MaNe a jumper for the N.C. safety contacts.
2- ChecN the application type selected. Select the type of automation with jumpers S1, S2, S3 and S4 as
described on page 10.
3- If installed, adjust the opening and closing stop limit switches.
NOTE: limit switches must be kept pressed until the operation has been completed.

commands.
If installed, checN that the limit switches are activated.
NOTE: if the direction of rotation of the motor is incorrect for the desired direction of the automation, swap
the power supply polarity 31-33 or 34-36.
6- If used, adjust the deceleration limit switches during opening and closing and set M1=MAX and M2=MAX.
Adjust trimmer VM and checN the opening speed and closing speed.NOTE: if the wings reach the mechanical stops too quickly, advance limit switch intervention.
7- If the limit switches are not used:
set M1=50%, M2=50% and VM=50%;
checN that the automation is operating correctly with subsequent opening and closing commands;WARNING: wait for the operation to complete before giving the next command. adjust the operation time using trimmers M1 and M2 so that the wings approach the mechanical stops
slowly. We recommend setting a deceleration time that guarantees completion of the operation even in
the presence of friction or other adverse environmental factors (wind, ice, etc.).
8- Connect the safety devices (removing the relative jumpers) and checN they worN correctly.
9- If required, adjust the delay time during closing of motor 1 (M1) with trimmer TR.
10- If required, adjust the automatic closing time with the TC trimmer.
WARNING: the automatic closing time after a safety device has triggered depends on the DIP2 setting.
11- Set the obstacle thrust with the R1 trimmer.
NOTE: if the door wing closing second encounters an obstacle, both door wings are reopen and the

WARNING: check that the working forces exerted by the door wings are compliant with EN12453-EN12445
regulations.
12- If required, adjust the partial opening of motor 1 (M1) with trimmer RP.
13- If required, connect the radio receiver by placing it in the housing for plug-in cards AUX1 or AUX2 and

Set M1 so as to obtain slow down of the door wing
before the limit switch is triggered.
With the above connections, the wing stops when
the limit switch operates.
When the time set with M1 runs out:
on opening operation the slow down time is a
