Operating the positioner
In this case, enter operating point, test limits and limits for discrete analysis:
1. Turn until Code h1/h2/h3/h4/h5 appears.
2. Press , Code h1/h2/h3/h4/h5 blinks.
3. Turn to set the parameter selected.
4. Press
to confirm.
The travel range of open/close (on/off) is defined by the fail-safe position and the operating
point. As a result, the following parameters to determine the working range and set point
range are not analyzed and cannot be changed.
−
Lower travel/angle range value (Code 8)
−
Upper travel/angle range value (Code 9)
−
Lower travel/angle limit (Code 10)
−
Upper travel/angle limit (Code 11)
−
Set point, lower range value (Code 12)
−
Set point, upper range value (Code 13)
Discrete analysis
If the set point ( ) is below 'Limit operating
point' (Code 49 - h5) when the automatic
mode starts, the valve ( ) moves to the fail-
safe position. If the set point increases and ex-
ceeds 'Operating point limit', the valve moves
to the 'Operating point' (Code 49 - h1). The
valve moves back to the fail-safe position (0 %
in the example) if the set point then falls below
'Fail-safe action limit' (Code 49 - h2).
