Adjustment range/values [default setting]/description
8.1.5 [0.0] to 99.0 %
Lower range value for travel/angle in nominal or operating
range
The operating range is the actual travel/angle of the valve and
is limited by the lower travel/angle range value and the upper
travel/angle range value. Usually, the operating range and the
nominal range are identical. The nominal range can be limited
to the operating range by the lower and upper x-range values.
The value is displayed or must be entered. The characteristic is
adapted. The difference between the lower and upper x-range
values must be at least 1 %.
8.1.6 1.0 to [100.0 %]
Upper range value for travel/angle in nominal or operating
range
The value is displayed or must be entered.
The characteristic is adapted.
Example: The operating range is modified, for example to limit
the range of a control valve which has been sized too large.
For this function, the entire resolution range of the set point is
converted to the new limits.
0 % on the display corresponds to the adjusted lower limit and
100 % to the adjusted upper limit.
The difference between the lower and upper x-range values
must be at least 1 %.
8.1.7 [0.0] to 10000.0 s
Time required to move through the operating range when the
valve opens.
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.
8.1.8 [0.0] to 10000.0 s
Time required to move through the operating range when the
valve closes.
8.1.9 [Activated]/Deactivated
8.1.10 0.0 to 49.0 % [1.0 %]
If the set point w reaches up to the entered percentage at the
final value that causes the valve to close, the actuator is
immediately completely vented (with AIR TO OPEN) or filled
with air (with AIR TO CLOSE). This action always lead to
maximum tight-closing of the valve.
