DCP 100T Digital Controller Programmer Installation ManualEN1I-6241

In normal operation, the operator must not remove the

controller from its housing or have unrestricted access to

the rear terminals, as this would provide potential contact

with hazardous live parts.

Installation and configuration must be undertaken by

technically competent servicing personnel. This is covered

in the Installation Manual (see above).

1INTRODUCING THE DCP 100T

The DCP 100T Digital Controller Programmer is a powerful, easy-to-use 1

-DIN

setpoint programmer with full PID control capability (complete with Self-Tune and

Pre-Tune facilities). Its standard features are:

•Up to eight programs of up to 16 free-format (e.g. dwell, ramp, join or

end) segments each.

•Facility to join programs to one another in any sequence (maximum

program length 121 segments).

•User can change currently-running program segment.

•Delayed Start of Program facility.

•End of Program relay output.

•Universal input - thermocouple, RTD (Pt100) or DC linear

- user- selectable).

•Universal power supply (90 - 264V ac 50/60Hz).

•Configurable from front panel.

•Comprehensive front panel displays.

•Front panel sealing to NEMA 4 standard.

•Behind-panel depth only 100mm.

Optional features include:

•Remote control and selection of program (plug-in option).

•Up to four Event relay outputs (plug-in option).

•Second control output.

•Recorder output (setpoint or process variable).

•RS485 serial communications.

•User-definable program tag names

•Real Time Clock

1-1

•Support software (Off-Line Configurator, On-Line Graphic Program Editor) -

operates via RS485 communications link.

The Digital Controller Programmer has four operating modes:

Base Mode: Day-to-day PID control operations with no program running. In

this mode, a program may be selected to run.

Program Run Mode: A selected program is running, held or waiting for a

pre-defined delay before starting. In this mode, the operator can view

status and program information.

Program Define Mode 1

: Used to view/create/edit programs. This mode is

entered either from Base Mode (selected program may be edited/created)

or from Program Run Mode (currently-running program may be edited).

Controller Define Mode

: Used to define the Controller characteristics.
