7.7 Zero calibration
In case of inconsistencies in the closed position of the valve, e.g. with soft-seated plugs, it
might be necessary to recalibrate zero.
Risk of injury due to the actuator stem extending or retracting.
Do not touch or block the actuator stem.
The process is disturbed by the movement of the actuator stem.
Do not perform zero calibration while the process is running. First isolate the plant by closing
the shut-off valves.
The positioner must be connected to the supply air to perform the zero calibration.
A zero calibration is not possible if there is zero point shift of more than 5 %. In this case,
Code 54 is activated. The positioner must be re-initialized.
