Operation
8.3 Performing zero calibration
Risk of personal injury due to moving parts on the valve.
Î
During zero calibration, do not insert hands or fingers into the valve yoke and do not
touch any moving valve parts.
Î
Do not block the actuator stem.
In case of inconsistencies in the closing position of the valve, e.g. with soft-seated plugs, it
might be necessary to recalibrate zero over Code
P23 .
Start zero calibration:
Î
Enable configuration (Code P2).
1. Turn until Code P23 appears.
2. Press and hold for 3 s (reading: 3 ... 2 ... 1 ).
Î
Zero calibration starts. P23 and ZERO blink during the calibra-
tion procedure. The positioner moves the control valve to the
CLOSED position and recalibrates the internal electric zero point.
Î
When the zero calibration has been successfully completed, the
positioner changes to closed-loop operation.
Canceling zero calibration
Zero calibration can be canceled:
Cancel zero calibration:
1. During zero calibration, press . Code
P23 and ESC blink.
2. Press again. Zero calibration is canceled.
Î
The positioner changes to closed-loop operation without perform-
ing a zero calibration. A new zero calibration can be started di-
rectly afterwards.
