3.6.5 SHUT_CLS – Shut-o ff value 0%
The shut-o ff value SHUT_CLS is a percentage of the
operating range (with one deci mal place) from which the 0 %
position is approached. Once th e speci
fi ed position limit value
is reached, the actuator move s into the 0% end position.
As a result, the valve is move d in control mode into the
mechanical 0% end position through full evacuation or
ventilation.
In the 0 % end position, it continues to be adjusted to the
position setpoint.
3.6.6 SHUT-OPN – Shut-o ff value 100%
The shut-o ff value SHUT_OPN is a percentage of the
operating range (with one de cimal place) from which the
100 % position is approached . Once the speci
fi ed position
limit value is reached, the actuator moves into the 100%
mechanical end position.
In the 100 % end position, it continues to be adjusted to the
position setpoint.
When entering a value, the valv e is moved in control mode into
the mechanical 100% end positi on through full evacuation or
ventilation.
Settings for Autoadjust:
Rotary actuators = 99 When the limit value is reached, the
actuator is fully ventilated.
Linear actuators = 100 Controlling continues in the 100% position.
3.6.7 RAMP UP – Setpoint ramp (up)
Here the stroke time for the actuator can be increased. A
setpoint change is not directly transferred to the positioner;
instead, the speed is reduced accordingly. The set value
should always be greater than the shortest stroke time
determined during auto adjust.
NOTE
To display the stroke time (stroke time up), press and hold
the
ENTER button.
CAUTION
The setpoint ramp is deactivated in the case of any functions
which involve approaching the safe position. This even
applies in the case of errors.
The actuator will therefore move without delay.
— Do not reach into the adjustment mechanism.
3.6.8 RAMP DN – Setpoint ramp (down)
Here the stroke time for the actuator can be increased. A
setpoint change is not directly transferred to the positioner;
instead, the speed is reduced accordingly. The set value
should always be greater than the shortest stroke time
determined during auto adjust.
NOTE
To display the stroke time (stroke time up), press and hold
the
ENTER button.
CAUTION
The setpoint ramp is deactivated in the case of any functions
which involve approaching the safe position. This even
applies in the case of errors.
The actuator will therefore move without delay.
— Do not reach into the adjustment mechanism.
