Setting the Type of Setpoint Control
Each setpoint can be configured so that it represents a pressure value or position value.
The [T x value] command configures the unit for setpoint control, where:
x: 1 = Setpoint A control
2 = Setpoint B control
3 = Setpoint C control
4 = Setpoint D control
5 = Setpoint E control
6 = Analog setpoint control
value: 0 = Position control
1 = Pressure control (initial)
To configure setpoint A for pressure control, enter:
T 1 1
Note
The RS-232 [T6 value] command overrides the digital logic control for the analog setpoint.
To report the type of valve control for a particular setpoint, issue the request:
R xx
where xx: 25 = Analog setpoint control
26 = Setpoint A control
27 = Setpoint B control
28 = Setpoint C control
29 = Setpoint D control
30 = Setpoint E control
The controller responds with the message [T x type], where:
x: 0 = Setpoint A control
1 = Setpoint A control
2 = Setpoint B control
3 = Setpoint C control
4 = Setpoint D control
5 = Setpoint E control
type: 0 = Position control
1 = Pressure control
