Note
If the devi
ce is being operated on a cylinder, for reasons
associated with linearity you should run the Auto Adjust function
for rotary actuators (see chapter Start automatic adjustment on
page 43).
A
A
EDP300 control unit with EDP300 remote sensor
In this version, the components are supplied in two housings,
which together form one harmonized unit.
The following points should be observed during installation:
•
Housing 1 (EDP300 Control Unit) contains the electro
nics
a
nd pneumatics and is mounted separately from the
actuator.
•
Housing 2 (EDP300 Remote Sensor) contain
s the position
se
nsor and is mounted on the linear and rotary actuator.
Mechanical mounting is described in chapter Mechanic

Note
To connect the EDP300 Remote Sensor, a cable with the
following specifications needs to be used:
•
3-wire, cross-section 0.5 to 1.0 mm
²
•
shielded, with at least 85 % coverage
•
Temperature range up to at least 100 °C (212 °F)
The cable glands must also be approved for a temperature range
up to at least 100 °C (212 °F). The cable glands require a
mounting for the shielding and strain relief for the cable in
addition.
ABB optionally offers a cable gland and cable for the EDP300
Remote Version.
B
EDP300 Control Unit for remote position sensor
In this version the positioner is supplied without a position
sensor.
The following points should be observed during installation:
•
Housing 1 (EDP300 Control Unit) contains the electro
nics
a
nd pneumatics and is mounted separately from the
actuator.
•
The remote position sensor is mounted on th
e linear
act
uator or rotary actuator. Follow the oper
ating
instructions for the

sition sensor for
mech
anical mounting!
