1.0 OVERVIEW

1.1

The CDM-2100 control panel consists of the DSG-1611DUPS instrument, wiring

terminals, and fuse installed in an industrial enclosure.

1.2 The CDM-2100 controller is a dedicated electronic microprocessor-based system

designed to sense differential pressure across a single catalyst element. A front

mounted keypad serves as the user interface for all required system configuration.

A backlit 128 x 64 character graphic display shows system status, programmed

controller parameters and channel labels. The controller provides complete

supervisory and alarm annunciation capability dedicated to monitoring and

protecting catalyst elements indicating when internal pressures have risen above

manufacturers limits.

In conjunction with the CDM-2100 controller, a highly accurate, low pressure

inches of water column differential pressure transmitter is used. When each port

of the differential pressure transmitter is placed across the catalyst element,

it sends an electronic signal back to the CDM-2100. This signal represents the

amount of pressure drop across the catalyst element.

2.0 CDM-2100 PANEL

2.1

The panel contains all the necessary hardware and provides the wiring interface

to an external sensor. Conduit openings at the bottom of the enclosure provide

access for supply power, sensor and other necessary wiring.

3.0 CDM-2100 DISPLAY MODULE

3.1

The CDM-2100 display module provides for monitoring the catalyst differential

pressure. The output of the CDM-2100 instrument provides a 4-20mA signal

representing the incoming pressure, and alarm outputs as discrete contacts.

3.2 The keypad is a sealed membrane unit containing MENU/ESC, UP, DOWN and

ENTER keys, used to navigate through channel status and description and to

edit the setpoints.

3.3 The LCD has a Home Screen that displays a Status Line, along with the catalyst

differential pressure in inH2O.

3.4 The keypad and display are used to navigate through channel status and

descriptions, view screens, and to view or edit the system's configuration.

Pressing the MENU/ESC key advances the display to the menus. All menu

adjustments are saved in non-volatile EEPROM memory by pressing the ENTER

key. The EEPROM memory retains the current configuration during normal

operation, after engine shutdown and a system power-down.

3.5 The CDM-2100 has serial communications compliant to Modbus RTU standard

and uses RS-485 for its hardware communication format.

4.0 MOUNTING THE PANEL

4.1

Mount the control panel(s) to a post or to a suitable flat surface so that the

display is at a convenient viewing height.

(FIG. 1)

NOTE: Avoid mounting the panel

with the LCD display facing direct

sunlight. The display operating

temperature range is -31°F to +176°F

(-35°C to +80°C). The panel(s)

should be mounted within 10–20

feet of the engine, the fuel solenoid

valve and sensors.
