5.0 WIRING

(SEE WIRING DIAGRAM, FIG. 2)

5.1

Wire Cable Assembly 693158-XX, where XX may be -60, -120, -360 (which

represents the cable length in inches) cabling, into the panel. This assembly

contains the wiring for the connection to the differential pressure transmitter.

Feed the cable through the bottom of the panel and connect each wire to its

appropriate position on the terminal strips. Separate power wiring must be routed

to the panel, and must follow guidelines published by the NEC and local authority.

6.0 KEYPAD DESCRIPTION

6.1

The CDM-2100 gauge features a four-key front keypad which is used to view or

change the setpoint values, configure and calibrate the gauge. The front panel

keys are MENU/ESC, ENTER, and ,  (up and down arrow keys).

6.2 MENU/ESC

The MENU/ESC key is used to enter the main menu and to return to the home

screen at any time. If the MENU/ESC key is used to return to the home screen

prior to pressing the ENTER key, changes are not stored in the memory and do

not take effect.

6.3 ENTER

The ENTER key is used throughout the menu to proceed through the

configuration and to accept the data to be saved. Throughout configuration

when a change has been made and is to be saved to memory, press ENTER and

the display will read SAVED, and the new data or configuration will be stored in

the nonvolatile memory.

6.4  AND 

The up and down arrow keys are used to scroll through the selections in the

menu and to increase or decrease values during configuration and calibrations.

Values can be changed incrementally using individual key presses or more

rapidly by holding the key down.

7.0 UNDERSTANDING THE HOME SCREEN

7.1

The CDM-2100 is considered in the HOME SCREEN when measuring and

displaying monitored data. The gauge displays up to a 5-digit numeric value

in 0.5" numbers, units of measure, the monitored point label, and a graph if

enabled. If a setpoint is configured and its value is exceeded, the output switch

turns on and the display will indicate SW1 LO, SW1 HI, SW2 LO or SW2 HI (low,

or high setpoint and switch 1 or 2 has tripped).

When the displayed reading exceeds the upper limit of the gauge (110% of

range), the display will read INPUT SIGNAL IS HI OUT OF RANGE, and if

configured, its high output switch will activate. If the displayed reading exceeds

the lower limit of the gauge, the display will read INPUT SIGNAL IS LO OUT OF

RANGE, and if configured, its low output switch will activate.
