<Positioner> function must be enabled and activated:
Function
In Split Range operation, a setpoint position E1 can be shared by up to three
positioners. A typical application example is a pipeline with a by-pass. The actuator
mounted on the by-pass reacts in the lower limit (e.g. 0 – 10 mA), the actuator on
the main valve in the upper limit (e.g. 10 – 20 mA). If the setpoint position is within
the setpoint range defined for the individual actuator, the actuator behaviour will be
identical to standard positioner operation. If the setpoint position is higher or lower
than the upper or the lower limit of the setpoint range of the respective actuator, the
actuator will run to positions OPEN or CLOSED.
The upper and lower limit of the respective actuator is defined via the analogue input.
(<Input range of setpoint position>)
In addition, the upper and lower limit of the total target value (valid for all actuators
grouped in a split range operation).
