— With the EDP300 designed for remote position sensors,
the positioner is supplied without a position sensor.
— The EDP300 Control Unit contains the electronics and
pneumatics along with the following options (where
applicable):
— Analog position feedback
— Digital position feedback
— Emergency shutdown module
— Universal input
Any position sensor (4 ... 80 kΩ) may be connected.
Connect the positioner (EDP300 Control Unit) and remote
position sensor while observing the following instructions:
— 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.
— 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.
— Use wire end ferrules when connecting.
— If the EDP300 Control Unit is attached so that it is it non-
conductive, the housing must be grounded (EDP300
Control Unit and remote position sensor with the same
electrical potential); otherwise control deviations could
occur with regard to analog position feedback.
— If the device is being operated on a cylinder, for reasons
associated with linearity you should run the Auto Adjust
function for rotary actuators
— The pneumatic outputs must be connected to the actuator
using pneumatic lines with a minimum diameter of 6 mm.
