DCP200 Profile Controller & Recorder - Product Manual

As the jacket temperature rises, the slave’s heater output falls. The product temperature also rises at a rate dependant on the transfer lag between the jacket and product. This causes the master’s PID output to decrease, reducing the ‘jacket’ setpoint on the slave, effectively reducing the output to the heater. This continues until the system becomes balanced.

When tuning a cascade system, first set the master to manual mode. Tune the slave controller using proportional control only (I & D are not normally required) then return the master to automatic PID mode before tuning the master. The result is quicker, smoother control with minimum overshoot and the ability to cope with load changes, whilst keeping the jacket temperature within acceptable tolerances.

Clock Configuration

A sub-menu of Configuration Mode used to adjust the parameters that relate to the settings for the Real Time Clock fitted with the data recorder option (Date, time, day of week and date format).

Also refer to: Data Recorder and Configuration Mode

Communications Write Enable

Enables/disables the changing of parameter values via the Serial Communications link, if a communication option such as Modbus RTU (RS485) or Modbus TCP (Ethernet) is installed.

When disabled, all communications are read-only.

 

Settings = Read Only or Read/Write.

Default setting = Enabled (read/write).

Also refer to: Ethernet, Modbus RTU, Modbus TCP, RS485 and Serial Communications

Configuration Menu

A selection of sub-menus from which the user can adjust the major instrument settings. There are sub-menus for the Inputs, Control, Outputs, Alarms, Communications, Recorder, Clock, Display and Lock Codes. Configuration Mode is entered from the Main Menu. An unlock code is required to access this mode.

Refer to the Configuration Menu information in the Configuration & Use section.

Contactor

- Refer to Relay

Control Configuration

A sub-menu of Configuration Mode used to adjust the parameters that relate to the control of the process. (Enabling control, auto/manual mode, control type and action, PID tuning terms, power limits, sensor break action, local setpoint values, setpoint ramp rates and setpoint selection).

Also refer to: Configuration Mode, Control Action, Control Enable, Local Setpoints, Manual Mode, PID, Power Limits, Sensor Break Pre-Set Power, Setpoint Ramping, Setpoint Selection and Tuning
