18.0 VIEWING THE TIME AND DATE OF THE FIRST FAULT
18.1 The DE-2200 monitor system “stamps” the time and date occurrence of the first fault. To
view the time and date of the first fault, press the F2 key after a fault occurs but before reset
is initiated. The time and date of the first fault will be displayed. If no key is pressed for 10
seconds, the display will revert back to the first fault screen. Press the ESC key to return to
the current home screen.

19.0 CONTRAST RATIO ADJUSTMENT
19.1 The LCD contrast ratio is adjusted for optimum contrast over a large temperature range at
the factory. It may be necessary however to make slight adjustments to the LCD contrast
ratio because of aging and or extreme temperature changes. The contrast ratio
potentiometer (TP1) is located on the back of the Display Module as shown in the drawings
section. Use an adjusting tool and turn the potentiometer clockwise to lighten the contrast
ratio or counterclockwise to darken the contrast ratio.
To set the potentiometer back to the factory setting: with the Display Module at an ambient
temperature of approximately 65
E
F to 77

until the display contrast ratio is almost too light to read. Turn the potentiometer
counterclockwise 3 to 3-1/2 turns. The display should then be at a desirable contrast ratio.
20.0 DATA LOGGING AND COMMUNICATION OPTIONS
20.1 The DE-2200 monitor system contains a data logging feature. Data logging collects
information from the system and keeps track of, or logs, that information over a period of
time. That data is then available through a PC or PLC at port 1, the RS-232 port or port 3,
the RS-485 port.
20.2 NODE NUMBER - The node number is the address of the monitor being contacted. This
number is programmed by the terminal program and can be viewed or edited in the menu
screen, refer to section 14.9. A two digit number from 01 to 99 can be used.
20.3 COMMUNICATIONS PARAMETERS - The following must be set in the PC or PLC to
communicate with the monitor system:
Baud Rate:
9600
Data Bits: 8
Stop Bits:
1
Parity:
None
