Initialise the path-measuring system
ATTENTION
Linear actuator starts up automatically!
Immediately upon connecting the power supply, the linear actuator moves
automatically to a path-measuring system reference point.
•
Wait until the reference point has been reached and the linear actuator stops.
The incremental path-measuring system must be initialised upon completion of
the following tasks:
•
In the event of initial start-up
•
After repairs to the valve or the actuator
•
After changing the valve or the actuator
The initialisation can be triggered in two ways.
Proceed as follows to initialise via the initialising button
WARNING
Electric shock due to live components!
Once the power supply has been switched on, there is risk of electric shock due
to live components.
•
Take care not to touch any live components.
•
Take care not to cause a short circuit on a printed circuit board with the tool.
