Note:
When initialization based on maximum range (default) is selected, the positioner can be
started up directly after being attached to the control valve via the SELF_CALIB_CMD par-
ameter.
The results of the initialization are saved in SELF_CALIB_STATUS. When this type of initializa-
tion is used, other parameters in this block generally do not require any adaptation.

Input:
Default:
S Fail-safe position of the actuator when the auxiliary power fails. It is determined
automatically during initialization.
UNINITIALIZED Not initialized, undefined
SELF-CLOSING Closing (in direction 0 % position)
SELF-OPENING Opening (in direction 100 % position)
INDETERMINATE None
S Manufacturer of actuator
Clearly identifies the manufacturer of the actuator associated with the positioner.
S Type / version of the actuator associated with the positioner.
S Serial number of the actuator associated with the positioner.
S Minimum transit time CLOSED position
The minimum transit time CLOSED (in direction 0 % position) is the actual time in
seconds which the positioner, actuator and valve need to move through the rated
travel/nominal angle to close the valve (measured during initialization).
S Minimum transit time OPEN position
The minimum transit time OPEN (in direction 100 % position) is the actual time in
seconds which the positioner, actuator and valve need to move through the rated
travel/nominal angle to open the valve (measured during initialization).
N Type of actuator associated with the positioner.
ELECTRO PNEUMATIC
S Actuator design with or without spring-return mechanism.
SINGLE ACTING single acting, with spring-return mechanism
DOUBLE ACTING double acting, without spring-return mechanism
SINGLE ACTING
