• riSE
• FALL
This parameter is used to set the setpoint direction. The setpoint
direction is used to reverse the direction of action of the setpoint.
• Rising (riSE): A higher value at the setpoint input results in
opening of the valve.
• Falling (FALL): A higher value at the setpoint input results in
closing of the valve.
The setpoint direction is primarily used for split-range mode and
for single-acting actuators with the safety setting "uP".
riSE
0.0 ... 100.0
With these two parameters in combination with parameter
"'7.SDIR' Setpoint direction (Page 160)", you can limit the effective
setpoint. This allows split range tasks with the following character-
istic curves to be solved:
• rising/falling
• falling/rising
• falling/falling
• rising/rising
With "SPRA": 0.0 With "SPRE": 100.0
