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 automatic adjustment before restoring the
factory settings!
Note
Before assembly, check whether the positioner meets the
control and safety requirements for the installation location
(actuator or final control element).
Refer to the Specification in 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.

Note
If the device is being operated on a cylinder, for reasons
associated with linearity you should run the Auto Adjust function
for rotary actuators (see Start automatic adjustment on
page 40).

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 Mechanical
mounting on page 16.
• Electrical connection is carried out as described in
Connection to device - EDP300 Control Unit with
EDP300 Remote Sensor on page 29.
