In the case of the "EDP300 Control Unit with EDP300 Remote
Sensor" design, the components are supplied in two housings,
which together form one harmonized unit.
Housing 1 (EDP300 Control Unit) contains the electronics and
pneumatics along with the following optional modules (where
applicable):
— Analog position feedback
— Digital position feedback
— Emergency shutdown module
— Universal input
Housing 2 (EDP300 Remote Sensor) contains the position
sensor and is suitable for mounting on linear or rotary
actuators.
If necessary, the following options can be installed if required:
— Optical position indication
— Mechanical feedback contacts designed as proximity
switches or microswitches.
The housings of the EDP300 Control Unit and the EDP300
Remote Sensor are available in stainless steel as an option.

Housing 2 (EDP300 Remote Sensor)
Connect the positioner (EDP300 Control Unit, housing 1) and
remote position sensor (EDP300 Remote Sensor, housing 2),
while following the instructions below:
— The EDP300 Remote Sensor and the EDP300 Control Unit
are adjusted to each other. Ensure that only devices with
the same serial number are connected.
— A shielded three-wire cable with a maximum length of
10 m (33 ft) must be used for connection purposes.
— Route the cable into the terminal compartment through
the EMC cable glands. Ensure that the shielding is
secured correctly in the EMC cable glands.
— Connect the cables in accordance with the electrical
connections and tighten the screws of the terminals so
that they are hand-tight.
— Use wire end ferrules when connecting.
— The electrical connections of the EDP300 Control Unit and
the optional modules are described in chapter "Electrical
connection to positioner / EDP300 Control Unit" on
page 18.
— If the EDP300 Control Unit is fastened so that it is it non-
conductive, the housing must be grounded (EDP300
Control Unit and EDP300 Remote Sensor housing with the
same electrical potential); otherwise control deviations
could occur with regard to analog position feedback.
— In the EDP300 Remote Sensor in IP rating IP 67, pre-
tighten the cover screws by applying approx. 50 Ncm
(0.44 lbf-in) and then tighten by applying 200 Ncm (1.77
lbf-in).
— The pneumatic outputs must be connected to the actuator
using pneumatic lines with a minimum diameter of 6 mm.
