Determination of the tolerance band in relation to the operating
range.
Associated lag time [30] s is a reset criterion.
If, during initialization, a transit time is determined which is
6 times > 30 s, the 6fold transit time is accepted as lag time.
Select the characteristic:
0: Linear
1: Equal percentage
2: Reverse equal percentage
3: Butterfly valve linear
4: Butterfly valve eq. percentage 9: User-defined *
* Definition over SAMSON TROVIS-VIEW software
The time required to pass through the operating range when the
valve opens.
Limitation of the transit time (Code 21 and 22):
For some applications it is recommendable to limit the transit time
of the actuator to prevent it from engaging too fast in the running
process.
The time required to pass through the operating range when the
valve closes.
Totaled double valve travel.
Can be reset to 0 via RES.
Limit value of total valve travel. If the limit value is exceeded, the
fault symbol and the wrench symbol appear.
Exponential display for 10 000 travel cycles onwards.
