…Control
Loop 1 Control Configures the basic type of control required and the PID (see page 30) and Autotune (see page 29)
settings.
Control Type Selects the basic type of controller required.
PID
Standard proportional, integral and derivative control.
On/Off
A simple 2-state control.
Note. Loop 1 output type must be set to Time Prop – see page 35.
Control Action If the required controller action is known it can be set using this parameter. Otherwise it can be set
to Unknown and Autotune (see page 29) determines and selects the correct action.
Direct
For applications where an increasing process variable requires an increasing output to control it.
Reverse
For applications where an increasing process variable requires a decreasing output to control it.
Unknown
For applications where the control action is not known (run Autotune to set the control action
automatically).
On/Off Hysteresis Refer to Basic Level on page 28.
Autotune Refer to Basic Level / Autotune on page 29.
PID Refer to Basic Level / PID on page 30.
