DCP200 Profile Controller & Recorder - Product Manual

Operation Mode

The mode used during normal operation of the instrument. It can be accessed from the Main Menu, and is the usual mode entered at power-up. The screens shown include a main screen with bar-graph, a trend view, information about the process, alarms plus optionally, selection of auto/manual control, control output disabling. Recorder and profiler information can be displayed if these features are fitted. Up to 50 configuration menu screens can be defined with the PC software, and will be shown if the Custom Display mode is enabled in the Display Configuration sub-menu.

Refer to the Operation Mode information in the Configuration & Use section.

Also refer to: Bar-Graphs, Configuration Mode, Custom Display Mode, Display Configuration, Main Menu, Profiler Setup Menu, Recorder Menu. and Trend Display.

Output Configuration

A sub-menu of Configuration Mode used to adjust the parameters that relate to the Outputs (Linear output type & scaling, output usage and scaling etc).

Also refer to: Configuration Mode and Linear Output.

Overlap/Deadband

The Overlap/Deadband parameter defines the portion of the primary and secondary proportional bands over which both outputs are active (called Overlap), or neither is active (called Deadband). This is adjustable in the range -20% to +20% of the sum of the two proportional bands. Positive values = Overlap, negative values = Deadband.

Overlap/deadband is applicable if the primary output is set for On-Off control or there is no Secondary Output. If the Secondary Output is set for On-Off, this parameter has the effect of moving the On-Off Differential band of the Secondary Output to create the overlap or deadband. When Overlap/Deadband = OFF, the edge of the Secondary Output Differential band coincides with the point at which the Primary Output = 0%.

The effect of the Overlap/Deadband parameter is shown in the following table

Settings = -20% to +20%.

Default value = 0.

Also refer to: On-Off Differential, On-Off Control, Primary Proportional Band and Secondary Proportional Band.
