The installer should be satisfied that, as a result of the mounting, the commissioning or as a result of
the test adjustments on the actuator, no potential hazards will be produced for devices/machines/
plant.
Before mounting the servo motor, check the free movement of the valve/device.
After completing the mounting and adjustment, check the correct functioning of the servo motor.
Safety advice for mounting and adjustments
The installer must be satisfied that, as a result of the commissioning or the test adjustments on the
servo motor, no potential hazards will be produced for personnel or the environment.
After completing adjustments check the correct functioning of the servo motor.
Check the correct functioning of any safety devices.
Carry out adjustments only in accordance with the instructions described in this documentation.
Adjustments must therefore be carried out only by a licensed electrician or a qualified person having
adequate training, who is aware of potential hazards.
Wiring
Five wires must be connected to power the servo. Cordsets are available for the FX04-1. Field
wirable connectors and cable are available for the FX04 (see page 5). Be sure to connect the ground
connection first to eliminate the ESD (electro static discharge) potential.
Use in a PPC4000 System
On a previously commissioned system, care must be taken when replacing a servo motor believed to
be defective. Although every effort is made to calibrate each servo, there may be slight differences
from servo to servo. It is strongly recommended the installer, equipped with a combustion analyzer,
use ADJUST RATIO to step through each profile that uses the replacement servo. Each profile set-
point should be checked and adjusted for proper combustion.
