2 - PRODUCT OVERVIEW
2.1 - Description of the product
The MEWA gear motors are destined to be installed in systems for
the automation of gates with hinged doors.
The MEWA gear motors have been designed and constructed to be
tted onto hinged doors within the weight limits indicated in the
technical specications table.
The use of gear motors for applications which differ from those
indicated above is prohibited.
2.2 - Model and technical characteristics
3 - PRELIMINARY CHECKS
Before installing this product, verify and check the following steps:
- Check that the gate or door are suitable for automation
- The weight and size of the gate or door must be within the maxi-
mum permissible operating limits specied in Fig. 2
- Check the presence and strength of the security mechanical stops
of the gate or door
- Check that the mounting area of the product is not subject to ood-
ing
- Conditions of high acidity or salinity or proximity to heat sources
could cause malfunction of the product
- Extreme weather conditions (for example the presence of snow,
ice, high temperature range, high temperatures) may increase the
friction and therefore the force required for the handling and initial
starting point may be higher than under normal conditions.
- Check that the manual operation of gate or door is smooth and
friction-free and there is no risk of derailment of the same
- Check that the gate or door are in equilibrium and stationary if left
in any position
- Check that the power line to supply the product is equipped with
proper grounding safety and protected by a magnetothermal and
differential security device
- Provide the power system with a disconnecting device with a gap
of contacts enabling full disconnection under the conditions dictated
by the overvoltage category III.
- Ensure that all materials used for the installation comply with cur-
rent regulations

4 - PRODUCT INSTALLATION
Unscrew the cover screws.
Loosen the screws to adjust the electrical limit switches until you are
able to scroll.
Screw in the desired position.
In case of installation of the second motor, follow the above
mentioned instructions for the mechanical mounting, for the electrical connections refer to the Fig.5.
4.4 - Mechanical and electronic connections of the second motor
4.1 - Installation
Before starting the installation, make sure that the product is intact
and that the packaging contains all the components shown.
Make sure that the mounting area is compatible with the overall
dimensions (Fig.1).
Check the allowed opening angle according to the xing points of the
brackets in Fig.3 and in the diagram in Fig.2.
Fig.4 is an example of a typical system:
- Operators (1)
- Photocells (2)
- Posts for photocells (3)
- Flashing light with integrated aerial (4)
- Key or digital switch (5)
Mounting the motor bracket to the pillar
Center the pillar bracket ssando previously traced by xing the
bracket using suitable screws and washers (not supplied) (Fig.1).
Fasten the motor to the pillar bracket with the screws and nuts
supplied. During this phase, make sure that the motor is perfectly
aligned.
ATTENTION: an off-axis mounting can cause malfunctioning
and damage the automation system.
Mounting the motor bracket
Move the gate leaf up to the maximum opening position.
Release the gearmotor.
Place the arm close to the leaf and lay on the leaf the gate bracket;
holding with one hand the bracket in contact with the leaf, try to
make a complete opening and closing movement.
Fasten the gate bracket to the leaf with suited screws (not sup-
plied).
Fasten the motor arm to the bracket.
Important: make sure that the bracket and the gate arm are
perfectly aligned.
ATTENTION: a not aligned mounting can cause malfunctioning
and damage the automation system.
4.3 - Electrical connections
Insert the supply cable to the terminal. Connect the wires of the supply cable to the terminal following the electrical drawing in Fig. 5.
4.2 - Adjusting the limit switch (230 Vac version)
