DCP200 Profile Controller & Recorder - Product Manual

Time Proportioning Control

Time proportioning control is accomplished by cycling the output on and off during the prescribed cycle time, whenever the process variable is within the proportional band(s). The PID control algorithm determines the ratio of time (on vs. off) to achieve the level of the correcting variable required to remove the control deviation error. E.g. for a 32 second cycle time, 25% power would result in the output turning on for 8 seconds, then off to 24 seconds. This type of output might be used with electrical contactors, solid state relays or solenoid valves. Time proportioning control can be implemented with Relay, Triac or SSR Driver outputs for either primary or secondary outputs.

Also refer to: Control Deviation, Correcting Variable, Current Proportioning Control, Cycle Time, PID, Primary Proportional Band, Relay, Secondary Proportional Band, Solenoid Valve, SSR and Triac.

Trend Display

Trend View is a graphical representation of recent process conditions. This feature is available on all variants. It does not rely on the Data Recorder option, and does not retain the stored data if the power is turned off. The trend shows the most recent 120 out of 240 stored data points. Its scale adjusts automatically for the best resolution for the visible data. This data can be the process variable; process variable & setpoint (shown as a doted line), or the minimum and maximum value of the process variable measured since the last sample. Any active alarm(s) are indicated above the graph. The user can scroll the right hand cursor line back to examine all 240 data points. The sample interval and data to display is set in Display Configuration.

Also refer to: Alarm Types, Display Configuration, Operation Mode, and Process Variable, Setpoint.

Tuning

PID Controllers must be tuned to the process in order for them to attain the optimum level of control. Adjustment is made to the tuning terms either manually, or by utilising the controller’s automatic tuning facilities. Tuning is not required if the controller is configured for On-Off Control.

Also refer to: Auto Pre-Tune, Controller, Derivative Action, Integral Action, On-Off control, PID, Pre-Tune, Primary Proportional Band, Self-Tune, Secondary Proportional Band and Tuning Menu.

Tuning Menu

The Tuning Menu can be accessed from the Main Menu. This menu is lock code protected. It gives access to the Pre-tune, Auto Pre-Tune and Self-tune facilities. These assist with PID tuning, by setting up Proportional band(s), Integral and Derivative parameter values. Tuning is not required for On-Off control.

Pre-tune can be used to set PID parameters approximately. Self-tune may then be used to optimise the tuning if required. Pre-tune can be set to run automatically after every power-up by enabling Auto Pre-Tune.

Refer to the Automatic Tuning information in the Configuration & Use section.

Also refer to: Auto Pre-Tune, Derivative Action, Integral Action, Lock Codes, Main Menu, On- Off control, PID, Pre-Tune, Primary Proportional Band, Self-Tune,Secondary Proportional Band and Tuning Menu.
