damage.
Important
Not performing the following procedures will invalidate the product warranty.
9 INSTALLATION
9.1 Checks to perform before installation
It is recommended to check the FTC smart positioner conditions before the installation:
- the pneumatic and electric port must be protected by plastic plugs until the installation phase;
- the supply circuit must be protected to prevent that the voltage or the current exceed the stated limits;
- the equipment must be provided with cable entries and filler plugs certified according to the required
certification.
9.2 Mounting on the actuator
It is recommended to follow these steps:
- remove the protection plastic plugs;
- mount the FTC smart positioner on the actuator by using the provided kit (typically the FTC smart
positioner can be mount on the actuator yoke or on the actuator top);
- the linkage must be able to generate a rotation angle between 30° and 120° during the full actuator
stroke. There are no mechanical stops on to the FTC shaft, thus there is no chance to damage the
FTC shaft by its over-rotation. An index show the correct shaft orientation;
- Backlashes, linearity errors and elasticity of feedback linkage could affect the FTC smart positioner
performance.

Warning
The FTC smart positioner shall have a proper earthing connection.
Figure 4 – FTC main connections
9.3 Earthing connection
The use of a ground strap between the FTC smart positioner housing and a suitable earthed point is
required. A proper connection could be done by the screw threaded in the FTC housing, as shown in the
following picture.

Warning
Check that the values of pneumatic supply available are compatible with those
reported on the label of the FTC smart positioner. User must consider and take all
precautions to avoid that pressurized parts are not used out of specified range
and to avoid exposure to fire.
Important
For easier maintenance, it is recommended to install a filter with five micron
cartridge and shut-off valve on the supply connection.
9.4 Pneumatic connections
It is recommended to follow these steps:
- the pressure line pipe has to be sized to avoid significant pressure drop during the actuator stroke;
- the piping between FTC smart positioner and actuator has to be ¼” and shorter as possible;
- during piping connection be careful to keep clean the internal side of piping and fittings, free from
threaded sealing material or any other contaminants;
- the FTC smart positioner is suitable for single acting actuators and double acting actuators (with or
without spring):
o
for double acting actuators (without spring):
i. Port IN must be connected to the supply line;
ii. Port OUT2 (or M6 thread hole) must be connected to the actuator chamber that has to
vent at signal fail position (no power);
iii. Port OUT1 must be connected to the actuator chamber that has to be pressurized at
signal fail position (no power);
o
for double acting actuators (with spring):
i. Port IN must be connected to the supply line;
ii. Port OUT2 (or M6 thread hole) must be connected to the actuator chamber that has to
vent at signal fail position (no power);
iii. Port OUT1 must be connected to the actuator chamber that has to be pressurized at
signal fail position (no power);
o
for single acting actuators:
i. Port IN must be connected to the supply line;
ii. Port OUT2 (or M6 thread hole) must be connected to the actuator chamber that has to
vent at signal fail position (no power);
iii. Port OUT1 must be plugged with tight plug suitable for the pressure rating and area
classification;
- no load or bending moment are allowed on pneumatic connection;
- the supply pressure must be lower than actuator design pressure;
- to check the correct mounting of the pneumatic connections, pressurize the FTC smart positioner
without any power signal and check if the actuator moves to the 0% signal position.
