1 GENERAL FEATURES
Electronic rotary gear motors of series AB1...SE have been newly conceived and specially
designed to be installed on residential and industrial combustion systems.
They are particularly suitable for control and regulation of modulating disc valves, butterfly
valves, dampers and other fluid regulation systems requiring control of position angle
within 90°. Electronic rotary gear motors are unipolar and bidirectional with high static and
maintaing torque. Analogic input signal according to current [4 ÷ 20 mA] or voltage change
[0 ÷ 10 Vdc].
WARNING
Installation, wiring, adjustment and maintenance of gear motors must be carried out
exclusively by skilled and authorized service technicians. Non-proper installation,
adjustment, modifications, use and maintenance may cause injuries to the staff or material
damages. It is therefore necessary to respect strictly the following instructions and local
prescriptions for the installation of electronic devices.

3 INSTALLATION
3.1 Make sure that all operating data indicated on gear motor plate correspond to the ones of
the systems.
3.2 When installing the gear motor make sure that there is sufficient clearance above the gear
cover and that it is easily accessible in order to perform wiring and endswitches
adjustment.
3.3 AB1...SE rotary gear motor is always supplied by the factory with standard endswitches
adjustment suitable for 90° rotation angle.
3.4 From a frontal view the motor shaft rotates:
- clockwise 3[closes] by decreasing of the input signal between terminals 2- 3
- counter clockwise 4[opens] by increasing of the input signal between terminals 2 -3
3.5 AB1...SE gear motor must be free to be stopped by its electronic endswitches; the
installation of mechanical locks or the presence of other obstacles could damage it.
3.6 AB1...SE gear motor can be installed in any environment included in the range of electrical
protection IP 54 and IP 65 except where acid fumes or other deteriorating vapours might
attack its metal parts or where gas leaks or explosive vapours are present in the
atmosphere. In environments with high salt percentage, fastening screws should be zinc or
cadmium plated and should not be made of brass or stainless steel.

4 WIRING
4.1 After having installed AB1...SE gear motor and before fastening it mechanically to the
device it has to operate, proceed with wiring and earthing.
4.2 Wiring diagrams are reported in the attached technical bulletin and on the plate inside the
cover.
4.3 WARNING
Before servicing make sure, that power supply is disconnected by means of the two-pole-
switch [phase and neutral]; in case of non-observance, damages to people and equipments
may occur.
4.4 In order to accede to the internal wiring terminal board, remove the cover by loosening the
4 fastening screws.
4.5 Two threaded holes for the fitting of the conduit plugs Pg 13.5 are present on the frame of
the AB1...SE gear motor.
4.6 All wires must comply with local prescriptions and, in any case, their section must be
ranging between 1 and 1.5 mm2. Connection piping recommended H07V-U…G1.5 mm2.
4.7 Connection wiring diagrams show AB1...SE gear motor at end position closed [0°].
4.8 Auxiliary microswitches are single-pole double through and voltage-free.
4.9 The rating of auxiliary microswitches is 0,5 A / 48 Vdc and Vac
4.10 Make sure that power supply and system frequency correspond to the values indicated on
the gear motor plate.
4.11 WARNING
Supply voltage of signal transmittor must be separated from the gear motor supply voltage
unless the transmittor is equipped with a separator transformer to avoid short circuits.
4.12 Low-tension signalling cable [tension lower than 48V] must be laid separately from the
higher-tension conduits [tension higher than 48V]. In case they are laid in a single channel,
screened cables must be used.
4.13 WARNING
Fasten the screws by means of an electrical or manual Screwdriver, which has a torque
lower than 0,5 Nm to avoid damages on the terminal box...

9 ADJUSTMENTS
9.1 ENDSWITCHES
As already reported in § 2 the AB1...SE electronic rotary gear motor is supplied by the
factory with adjustment foreseen for a 90° rotation angle. If higher or lower than 90°
rotation angles are requested, proceed as follows:
9.1.1 Disconnect the operating lever system of the gear motor shaft and remove the
cover.
9.1.2 For “CLOSED” position adjustment it is necessary to operate on cam “S1”.
For “OPEN” position adjustment, it is necessary to operate on cam “S2”.
9.1.3 For cam adjustment, use the proper “half-moon” key, supplied with the AB1...SE
gear motor equipment and installed inside.
9.1.4 Use the key from the right side, introducing the pin into one of the holes on the
sides oftheblue cam of the cam involved and lever it to desired position.
9.1.5 If the blue cam is in a behind position, use at first the lever on its curved side to
move theblue cam to a more suitable position to perform adjustment.
9.1.6 Cam adjustment is possible in both directions and along the whole rotation angle
of the cam shaft.
9.1.7 Remove the key before servicing.
9.1.8 Run the AB1...SE gear motor for a few cycles making sure that the right cam
adjustment has been achieved.
9.1.9 Once all adjustments have been carried out return the key inside the AB1...SE
gear motor and reinstall the cover by fastening the 4 screws.

mechanically connected in a correct and safe way.
Check that the levers' movements occur smoothly without jamming or blocking due to
other objects.
11 MAINTENANCE
The AB1...SE rotary gear motor does not require any particular current maintenance.
The AB1...SE gear motor does not require any lubrication because the gear mechanism is
immersed in a grease bath.
Do not disassemble any internal part of the AB1...SE gear motor. In case of non-
functioning, after having performed all possible checks on field, it must be returned to the
factory for any possible repair.
It is not advisable to perform any repair on field.

13 ELECTRONIC CONFIGURATION
The digital electronic board mounted on AR2 gear actuator enables to set various features
/ options, like rotation direction, resolution, type of input control signal and impedance.
WARNING
For each model there is a specific electronic board, with its own specification in hardware
and software.
The desired configuration can be obtained by setting dip-switch of the electronic board on
the right or left hand side, according to the below indicated schemes.
Dip-switches are located under the paperboard panel over the horizontal board. Lift the
rectangular paperboard to access the dip-switches
