DCP200 Profile Controller & Recorder - Product Manual

Deviation Alarm Value

Defines the amount of control deviation considered acceptable before a deviation alarm is activated. A positive value (deviation high) sets the alarm point above the current actual setpoint, a negative value (deviation low) sets the alarm point below actual setpoint. If the process variable deviates from the actual setpoint by a margin greater than this value, the deviation alarm becomes active. If an alarm is required if the control deviation is either side of the setpoint, consider using a Band alarm or a logical combination of a deviation high and deviation low alarm.

Settings = 1 LSD to full span from the setpoint

Default value = 5 LSD’s.

Also refer to: Actual Setpoint, Alarm Operation, Alarm Types, Band Alarm, Control Deviation, Logical Combination, Process Variable and Setpoint.

Digital Input

An input that can be driven to one of two states (active or inactive) by and external voltage or a contact opening/closing. Digital Inputs can be used to set the instrument in to different states. Possible uses are to select Auto/Manual Mode, Active Setpoint, Control Output Enable/disable, Profile Run/Hold/Abort, Hold Segment Release and Recording Start/Stop.

Also refer to: Active Setpoint, Control Enable, Data Recording, Manual Mode, Profiling and Segment Types.

Direct Acting Control

Direct action is required for applications where the primary control output will be used to force the process variable down towards the setpoint. A typical application is a Chiller. When the control action is selected as direct acting, primary proportional control outputs decrease the correcting variable as the process variable reduces within the proportional band, and primary On-Off outputs turn off when the process variable is less than the setpoint. The control action of a secondary output is always the opposite of the primary output.

Also refer to: Control Action, Control Type, Correcting Variable, On-Off Control, Process Variable, Proportional Control and Reverse Acting Control.

Display Configuration

A sub-menu of Configuration Mode used to adjust the display, and the parameters that relate to Operation Mode (Custom display enable, read-only operation mode, bar-graph formatting, trend setup, display colour & contrast and language selection).

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

Display Languages

The instrument supports two languages. The main language is English. The alternate language is chosen at time of order, but can also be changed by downloading a new file via the PC software. Current supported languages are English, French, German, Italian, Spanish, Russian and Czech.

Also refer to: Display Configuration, Operation Mode, and Main Menu.
