PROPORTIONAL BAND
Sets proportional gain (% power per unit error). Defined in same units and resolution as that for PV.
INTEGRAL TIME
Sets integral time constant in Seconds. Setting the value to 0, cuts-off the integral action.
DERIVATIVE TIME
Sets derivative time constant in seconds. Setting the value to 0, cuts-off the derivative action.
CYCLE TIME
Sets the total ‘On + Off’ time in seconds for time proportional power output through Relay / SSR for OP1.
OVERSHOOT INHIBIT
Set this parameter to ‘Enable’ if the process exhibits unacceptable overshoot upon start-up or a step change in SP. If enabled,
the controller controls the rate of change of PV to minimize overshoot while approaching the target SP.
CUTOFF FACTOR
This parameter adjusts the effectiveness of the Overshoot Inhibit feature. Increase the value if the overshoot is curbed but the
PV takes longer to reach the SP. Decreases the value if the overshoot persists.
