"1.3 Device replacement"
Requirement
● Replacement device is mounted. Refer to section "Mounting on actuator with OPOS
interface (VDI/VDE 3847) (Page 31)".
● Adjuster on pneumatic block of replacement device is set to "HOLD". You may want to
reset the "HOLD" position after execution of the menu, if necessary. Refer to section
"Settings on the pneumatic block (Page 134)".
Description
Use this menu to commission a replacement device without interrupting the running process.
An automatic initialization that could impair running operation will not take place.
To do so, you only set the most important characteristics for the positioner, e.g. nominal
stroke and actual position, and start the control function. Initialize the new positioner as soon
as possible after device replacement in order to ensure the following properties:
● Optimum adjustment of the positioner to the mechanical and dynamic properties of the
actuator.
● Unlimited accuracy or optimum dynamic performance of the positioner.
● Non-deviating position of endstops
● Correctness of the maintenance data
