Installation

6.1

Safety instructions

CAUTION
Risk of injury due to incorrect parameter values!
Incorrect parameter values can cause the valve to move
unexpectedly. This can lead to process failures and result in
injuries.
— Before recommissioning a positioner that was previously
in use at another location, always reset the device to its
factory settings.
— Never start Auto Adjust before restoring the factory
settings.
NOTICE
Before installation, check whether the positioner meets the
control and safety requirements for the installation location
(actuator or valve).
See the "Specifications" section on the data sheet.
Only qualified specialists who have been trained for these
tasks are authorized to mount and adjust the unit, and to
make the electrical connection.
When carrying out any work on the device, always observe the
local accident prevention regulations and the regulations
concerning the construction of technical installations.

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 electronics
and pneumatics and is mounted separately from the
actuator.
— Housing 2 (EDP300 Remote Sensor) contains the position
sensor and is mounted on the linear and rotary actuator.
Mechanical mounting is described in chapter "Mechanical
mounting" on page 13.
— Electrical connections are described in chapter "Electrical
connection to the EDP300 remote sensor" on page 19.
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 electronics
and pneumatics and is mounted separately from the
actuator.
— The remote position sensor is mounted on the linear and
rotary actuator. Follow the operating instructions for the
remote position sensor for mechanical mounting!
— Electrical connections are described in chapter
"Connection to device - EDP300 Control Unit for remote
position sensor" on page 23.
