Installation and commissioning of the electropneumatic actuators must be
carried out in accordance with instrumentation professional standards, and
in particular:
Warnings
CAUTION !
Piping:
When commissioning a new or modified installation, the piping must be
blown through before connecting the actuator in order to clear the circuit
of any impurities, which cannot be avoided during construction (iron filings,
scale, Teflon, welding flux, etc.).
Electric wiring: The power supply voltage and the value of the control
signal must be chec- ked before final connection.
SMARTRONIC MA box:
The covers and housings of the unit must be properly closed to protect the
contents from humidity and, generally, from the outer atmosphere
(”aggressive” atmosphere, dust, etc.) and any incidents which could
damage the internal parts.
Connection by cable gland:
When the electric connection is made through a cable gland, make sure
that:
- the cable gland is suitable for the cable diameter
- the cable gland is correctly tightened on the cable
The pneumatic connection must be provided according to the product specification.
(see IV -I Pneumatic connection)
Never exceed the values indicated in this manual!
This box is an electrical device which contains pressurized gas components. As such, it may be a source of
danger for property or even personnel. Exceeding the values indicated could result in damage.
Never uncouple or dismantle the SMARTRONIC MA box or its accessories when pressurised or
powered up.
Always make sure that the actuator and positioner reservoirs are decompressed before dismantling the dis-
tributor, its solenoid valves or the unit itself.
Also, always check that the power supply is disconnected from its source before any dismantling.
During checks in the workshop or on site, the valve associated with the actuator and positioner must
be operated from fully open to fully closed.
This operation could present a very high risk of injury unless minimum safety measures are taken to
prevent access between the disc and the seat.

I - Introduction
I -- 1 General
This manual describes the SMARTRONIC MA positioner. This device is designed to control the quarter- turn actuators
of the ACTAIR and DYNACTAIR range by direct surface mounting on the standardized VDI/VDE 3845 interface. It
provides both the direct pneumatic and mechanical link with the actuator chambers.
The positioner can also be mounted on any other VDI/VDE 3845 actuator using an adapter kit (see §XII - Spare parts kit)
I - 2 Operating principle
This device is asequential digital positioner. Itis equipped with anon/off 3- position actuator control distributor with
valves. On loss of electrical power, the valve moves to the safety position configured when ordering the
SMARTRONIC MA positioner.
The actuator is positioned by energizing either of the control solenoid valves.
These solenoid valves are controlled by the electronic board which reacts according to the difference between the
position (angle sensor signal) and the control signal by adopting one of the three possible states:
Positive difference = Opening
Zero difference = Position held (no action)
Negative difference = Closing
The control is of the PWM (Pulse Width Modulation) type. Using a fixed basic frequency (Fo), the principle consists in
modulating the pulse width according to the position/set point difference.

III - Assembling the SMARTRONIC MA/Actuator assembly on the valve
Use of an angle sensor with no mechanical stops makes it easier to assemble the positioner on the valve.
It is essential to perform a complete opening/closing cycle up to the actuator mechanical stops so that the angle sensor takes up
the correct position.

MA Pipe
Actuator + Smartronic MA
IV - Pneumatic supply
IV - 1 Pneumatic connection
The pneumatic distributor operates with air filtered to 15 m. Before making any pneumatic connections, check that
there are no impurities in the piping, especially when starting the installation. As a safety measure, a sintered bronze
filter is fitted in the unit intake hole to prevent the pneumatic distributor from being blocked or damaged by impurities.
This filter can be cleaned if it becomes clogged.
Take it out and clean it with a solvent and/or compressed air (blower).
Power supply Exhaust
The connection is made on the SMARTRONIC MA box.
Operating pressure: 2 to 7 bars
Pressure connection: hole ”P”
Exhaust connection: hole ”E” equipped with a silencer or connectable to an
exhaust network.
Caution: When used as a position regulator, use air lubricated with 5 mg/m3to
prevent premature wear of the actuator mechanical parts.
Attention: If severe vibrations are expected or excessive tensile strain
(max. 80 kg) needs to be prevented at the ¼" gas thread connections,
the use of flexible tubing is strongly recommended for pneumatic connection.

IV - 2 Mechanical adjustment of the operating time
Mechanical adjustment of the operating time is carried out in the factory to obtain the best accuracy/speed
compromise for the positioner.
Mechanical modification of the operating times could prevent the positioner from operating correctly.
After making these modifications, it is essential to perform autocalibration.
Opening and closing times of at least 0.5 s must be respected for autocalibration to be carried out correctly.
The valve operating time can be adjusted using the adjustment screws located on the side of the base, beside the
exhaust hole. Adjustment is carried out directly with a 4 mm flat screwdriver.
Procedure :
- Adjust the adjustment screws depending on the type of actuator used.
- Use MANUAL operation to test adjustment of the operating time (MANUAL mode: see § VII - 3 - 2 ).
- Restart autocalibration (see § VII - 2)
For information, the following minimum operating times can be obtained:
(reducing the operating time may impair the positioning accuracy)

IV - 3 Safety position on loss of current
The safety position on loss of current of the SMARTRONIC MA is configured in the factory according to the order.
IV – 3 - 1 STOP function by lack of power (R131* / ****1**SB*C2*0600)
This function is only available for SMARTRONIC MA units (DOUBLE ACTION version).
A specific version of the pneumatic valve is used for this feature.
Either plate A or B can be used.
Note : If plate A is replaced by plate B (or conversely), self-calibration must be initiated.
IV – 3 - 2 OPENING/CLOSING function by lack of power (R131* / ****1***B*B2*0600
and R131* / ****1***B*A2*0600)
The opening/closing function by lack of power is defined by the distribution plate (Plate A or B).
