SP7-10, SP7-11, SP7-12 and SP7-20, SP7-21, SP7-22 Parameterization
The shut-off value SHUT_OPN is a percentage of the operating range (with one decimal place) from which the 100 % position is
approached. Once the specified 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 valve is moved in control
mode into the mechanical 100% end position 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)
3.6.5 SHUT_CLS – Shut-off value 0%
The shut-off value SHUT_CLS is a percentage of the operating range (with one decimal place) from which the 0 % position is approached.
Once the specified position limit value is reached, the actuator moves into the 0% end position.
As a result, the valve is moved 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-off value 100%
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 timel 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 appl ies in the case of errors.
The actuator will therefore move without delay
- Do not reach into the adjustment mechanism.
