7.12 Canceling initialization
1. Press the button.
– Canceling automatic initialization: the display shows "INITA".
– Canceling manual initialization: the display shows "INITM".
The positioner is in the "Configuration" mode.
2. Exit the "Configuration" mode. To do this, press the button for at least 5 seconds.
The software version is displayed.
After releasing the button, the positioner is in "P manual mode". The positioner is not
initialized.
7.13 Device replacement
Introduction
Note
Initialization
The positioner can be replaced without having to interrupt the ongoing process. However,
copying and transferring of the initialization parameters only allows an approximate adjustment
of the positioner to your actuator. Following initialization, the positioner initially works with the
manually defined parameters.
● For this reason, an automatic or manual initialization should be carried out as soon as
possible.
Note
Deferred initialization
Initialize the new positioner as soon as possible. The following properties can be ensured only
after initializing:
● Optimum adjustment of the positioner as per the mechanical and dynamic properties of the
actuator
● Non-deviating position of endstops
● Correctness of the maintenance data
There are two ways of replacing a positioner when the equipment is in operation, without having
to interrupt the process. The two options depend on whether your positioner has
communication.
First possibility - with communication
1. Read the initialization parameters from the previous positioner. Use the parameter
assignment tools suitable for this purpose.
2. Transfer the initialization parameters read in the parameterization software under Point 1
into the new positioner.
