Loop/tag number Loop/tag number - text that is associated with the field device installation. This text can be
used by the user in any way. Each field device is recommended to be assigned a unique
loop/tag number.

Minimum control pulses Shortest pulse supplied to the supply air or exhaust air valve. The pulses for the travel
ranges 0 to 20 %, 20 to 80 % and 80 to 100 % are determined separately!
States: None..................................no pulses determined yet
Exhaust air .........................pulse for exhaust air determined
Supply air ...........................pulse for supply air determined
Valid...................................pulse for exhaust and supply air determined
Minimum transit time
(filling/venting)
The minimum transit time, in seconds, for filling or venting air from the actuator during
initialization is measured separately for supply and vented air. The transit time is defined as
the time required by the system comprising positioner, actuator, and valve to pass through
the rated travel /nominal angle.
