DCP200 Profile Controller & Recorder - Product Manual

Profiler

A profiler controls the value of the actual setpoint over time; increasing, decreasing or holding its value as required. This is used in applications where the rate of rise or fall of the process variable must be closely controlled, or where a value must be maintained for a period before moving to the next value.

If the Profiler option is fitted, up to 64 profiles can be created with a maximum of 255 profile segments shared amongst them. Each segment can activate/deactivate the five events according to the requirements of the process.

Refer to the Profiler Option section.

Also refer to: Actual Setpoint, Controller Mode, Profile Events, Profile Control Menu, Profile Header, Profile Segments, Profile Setup Menu and Profiler Mode.

Profiler Mode

This mode is entered when a profile is run. In profiler mode, additional screens are added to Operation Mode which show the status of the profile. These screens are not seen in Controller Mode. The instrument will remain in Profiler Mode when the profile finishes or is aborted unless the Segment End Type/Profile Abort Action is set to “Use Controller Setpoint”.

Also refer to: Controller Mode, Profile Control Menu, Profile Segments, Profile Setup Menu, Profiler and Setpoint.

Proportional Control

Proportional control allows the correcting variable applied to the process to be set between 0 and 100% of the amount available. If the control type is dual, two outputs (primary & secondary) are available, each of which can give proportional control. When the Proportional Band(s) are correctly tuned, the process variable is maintained at a steady value, avoiding the oscillation characteristic of On-Off control. Proportional control is most commonly used in conjunction with Integral and Derivative action to give PI. PD or PID control.

Also refer to: Control Type, Correcting Variable, Derivative Action, Integral Action, On-Off Control, PD, PI, PID, Primary Proportional Band, Process Variable, Secondary Proportional Band, Setpoint and Tuning.

Rate

-Refer to Derivative Action.

Rate Of Change Alarm

An alarm based on the rate of change in the measured process variable. If the PV changes at a rate greater than the alarm level, the alarm will activate. The rate of change must be above the alarm threshold for longer than the Minimum Duration Of Change time, before the alarm will change state (from on to off, or off to on). Caution: If the duration is less than this time, the alarm will not activate no matter how fast the rate of rise.

Also refer to: Alarm Hysteresis, Alarm Operation, Alarm Types, Minimum Duration Of Change and Process Variable.

Recorder Configuration

If the Data Recorder is fitted, a Recorder Configuration sub-menu is added to Configuration Mode. This is used to adjust the recorder parameters (Recording mode, sample interval, trigger and values to record) and to show the recorder status.

Also refer to: Configuration Mode, and Data Recorder
