No overshoot or undershoot of the PV setpoint e Quick response to deviations from the setpoint caused by external disturbances thereby rapidly restoring the PV to the setpoint value Tuning is normally done automatically by setting the AUTO TUNE ENABLE parameter to 11 2 1 Automatic Tuning This controller uses a one shot tuner which automatically sets up the initial values of the parameters listed in section 11 1 The one shot tuner works by switching the output on and off to induce an oscillation in the measured value From the amplitude and period of the oscillation it calculates the tuning parameter values Following a tune the instrument will modify the control parameters to match the characteristics of the load On starting the tune there is a one minute delay while the loop is allowed to settle During this time you may edit the loop setpoint Care should be taken to ensure that the oscillations of the process value will not damage the process being tuned It is recommended to set the setpoint for tuning purposes below the normal running setpoint value If the process cannot tolerate full heating or cooling being applied then the levels can be restricted by setting the high power limit GP H I and low power limit GP L 0 However the measured value must oscillate to some degree for the tuner to be able to calculate values A one shot tune can be performed at any time but normally it i

This is referred to as the control loop or closed loop control 11 1 PID Control The PID controller consists of the following parameters Parameter Meaning or Function Proportional Band The proportional term in display units or delivers an output which is proportional to the size of the error signal Integral Time Removes steady state control offsets by ramping the output up or down in proportion to the amplitude and duration of the error signal Derivative Time Determines how strongly the controller will react to the rate of change in the measured value It is used to prevent overshoot and undershoot and to restore the PV rapidly if there is a sudden change in demand High Cutback The number of display units above setpoint at which the controller will increase the output power in order to prevent undershoot on cool down Low Cutback The number of display units below setpoint at which the controller will cutback the output power in order to prevent overshoot on heat up Relative Cool Only present if cooling has been configured Gain Sets the cooling proportional band which equals the heat proportional band value divided by the cool gain value 11 2 Tuning In tuning you match the characteristics PID parameters of the controller to those of the process being controlled in order to obtain good control Good control means e Stable straight line control of the PV at setpoint without fluctuation e
