880R-N4X
1.0 Introduction
The Detcon Model 880 Remote Display unit is specifically designed to serve as a Remote Monitor for the
Model 880 PLC Control Units. The Model 880RA-N4X is designed to work with the Model 880 Analog
versions, and the Model 880RS-N4X is designed to work with the Model 880 Serial versions PLC Graphic
Controllers. The NEMA 4X rated enclosure is rain tight and suitable for outdoor locations in electrically nonhazardous environments. The unit features a color touch screen that graphically displays the status of each
device attached to the Model 880 PLC Control Unit.
2.0 System Configuration
2.1 Touch Panel Graphic Display
The Model 880 is equipped with a graphic display panel (Figure 1) that is prompted to display information
such as the operational status of each monitoring device, alarm output readings, and record alarm incidents to a
USB Drive.

The touch panel acts as a master interface to the remotely located PLC. As such, the touch panel polls the
PLC, which, in turn, polls the field devices for information. A wand is used on the screen to operate system
controls and/or move to additional screens.
A USB port (Figure 1) is located on the back of the display at the bottom. When a USB Drive (USB Memory
Stick) is installed, the display will automatically log to the drive where any alarms and/or faults have been
recorded by the PLC. The information is logged into a folder named ‘Log’ and named ‘Alarm_yymmdd.txt’
where yy is the year, mm is the month, and dd is the day. The files are written in text format.

Figure 7 Typical Input Power connections
Upon completion of all field wiring, apply power to the Main 880 and the 880 Remote Display. The unit will
go through a brief initialization and display the “Main Screen” (Figure 15). The “AC” box on the display
should be green to show that AC is attached to the unit. The “USB” box gray to indicate no USB drive is
attached.
4.0 Setup
4.1 User interface
When an alphanumeric or text string is called for, the unit will display an alphanumeric keyboard for the user
to input information (Figure 8). Information typed by the user will be displayed in the box just above the
keyboard. The keyboard is fully functional allowing the user to input spaces, special characters (‘*’, ‘&’, etc.),
and make changes between lowercase characters and capitals by using the CAP key. Once the user has input
the correct information, the ‘Enter’ key will transfer the complete string to the appropriate ‘Box’ on the screen
and the alphanumeric keyboard will disappear.
Figure 8 Input Keyboard
When a number is called for, the unit will display a keypad for the user to input the appropriate numeric
response (Figure 9). Information entered by the user will be displayed in the box to the left of the keypad.
Once the user has input the correct information, the ‘Enter’ key will transfer the numeric value to the
appropriate ‘Box’ on the screen and the keypad will disappear. Many keypad entries display a minimum,
880R-N4X Instruction Manual Rev. 0.0 Page 5 of 16
880R-N4X
maximum, and current box. These boxes show the lower limit, upper limit, and current value of the number
being entered. Numeric entries outside of these restrictions will not be accepted.
Figure 9 Input Keypad
The display screen also contains a number of “buttons”. These “buttons” act as toggle switches that change
state when activated by the wand. These buttons will indicate the change in state by some obvious means such
as a change in color, name, or both (i.e., when changing the state of an alarm from ascending to descending the
button will change from a blue button displaying “ASC” to a gray button displaying “DES”).
4.2 Clock and Screen Adjustments
Adjustments to the clock and screen are made entering the display’s Setup Screens. Only the Clock and
Screen adjustments are discussed here. Changing other aspects of the Display Touch Panel may cause the
system to operate improperly and should not be attempted.
Access the display’s System Setup Screens by touching the upper left corner of the touch panel with the wand
and holding it there for 3-5 seconds. A warning box will appear (Figure 10). If no action is taken within 60
seconds, the system will return to the Main Screen. To return to the Main Screen select “Exit”.

4.3 880 Remote Display Setup
The remote display must be setup to match the main 880. The screens are duplicates of the Main 880;
therefore, the setup is accomplished in much the same manner as the main unit. If the 880 Remote Display is
not set up to match the Main 880, the resulting displays will be inconsistent and erroneous.
1) From the “Main Screen” (Figure 15), enter the “System Configuration Screen” by touching the “System
Configuration” box with the wand.
2) The display will prompt for a password to enter the 880 “System Configuration Screen”. The default
password is “1234”. Enter the password in the Pop-Up Screen and press enter to continue. This will open
the “System Configuration Screen” (Figure 16 – Analog, Figure 17 - Serial).

5) Select the “EXIT” box to exit the “System Configuration Screen” and return to the “Main Screen”.
6) The “Channel Description”, “Gas Type”, and the range decimal point must be setup in the Remote Display
to match the information used to setup the Main 880. Sensor Range and Alarm information should not be
altered at the Remote Display. (This information is transferred over from the Main 880). Using the wand
to select a channel from the “Main Screen” will open that channels corresponding “Channel X Details
Screen” (Figure 20).
880R-N4X Instruction Manual Rev. 0.0 Page 10 of 16
880R-N4X
Figure 20 Channel Detail Screen
a) Select “Channel Description”. The keyboard will appear, allowing the input of the Channel Tag
Name, or a brief description of the sensor, up to 20 characters maximum. The “Channel Description”
here must match the “Channel Description” entered at the Main 880.
b) Select “Gas Type”, and input the gas type of the sensor. (i.e., H2S, LEL, CO2, etc.) Up to 10
characters maximum. The “Gas Type” entered here must match the “Gas Type” entered at the Main
880.
c) The Range of the sensor is transferred by the Main 880 and should not be changed in the Remote
Display. However, the decimal point must be set for the range to be correctly displayed. Therefore
ranges of 10 for a unit of 10ppm or 10% will be displayed as 100, likewise entries of 5 for 5ppm or
5% will be displayed as 500. To correctly place the decimal point in the entry, select the “Decimal
Place” box and enter the decimal point placement. (i.e., a “Range” entry of 100 with a “Decimal
Place” of 1 provides a range of 10.0, 10ppm or 10%. Likewise, a “Range” entry of 500 with a
“Decimal Place” of 2 provides a range of 5.00, 5ppm or 5%.)
7) Proceed through all channels, setting each channel’s “Channel Description” and “Gas Type” to that setup
in the Main 880. When all channels have been correctly set-up the unit should be ready for normal
operation.
5.0 System Operation
The touch screen display serves as the graphic user interface to the system. Maneuvering through the system
screens and accessing data fields is accomplished by touching the wand to the appropriate area, box, button, or
key on the screen. The provided “wand” should be the only instrument used to activate the screen as other
instruments may cause damage to the screen.
5.1 Main Screen
The main screen is the default screen of the unit (Figure 21). The screen displays the first 8 channels, channel
descriptions, current readings, gas type, and sensor status for each channel. If the status of a sensor is such that
880R-N4X Instruction Manual Rev. 0.0 Page 11 of 16
880R-N4X
the sensor is in an alarm condition, the corresponding “FLT”, “ALM1”, “ALM2”, “ALM3”, or “COM” will
blink to signify that condition. Touching a channel number (Ch-X) will open the corresponding channels
“Channel X Details Screen”. This screen will provide more information on the selected channel.
Near the top left of the screen, just below the Detcon Logo, there will be 2 to 9 selection buttons (Labeled “18,” “9-16,” “17-24,” etc.) dependent on the total number of channels set up in the “System Configuration
Screen.” These buttons represent the pages that display the associated 8 channels; up to page 9 (Channels 65-
72). Selecting any of these buttons with the wand will open the corresponding page to display those
corresponding channels. These pages are all duplicates of the main page, with the exception of the channels
being displayed.
Figure 21 The Main Screen
Each channel is displayed as a separate line item on the main screen. Each channel has its own “Channel
Detail Screen”. To open a channels detail screen touch the appropriate channel with the wand, this will open
the associated channels detail screen (Section 5.2).
A row of boxes is located at the bottom of the screen. The second box displays the time and date.
The “AC” box is green when the unit is running on applied AC or if applicable the Auxiliary 24VDC Input.
“USB Out” displays the status of the USB port on the back of the display. When a USB Drive is not installed,
the button will be gray and display “USB Out”. When a USB Drive (USB Memory stick) is installed, the unit
will go through an initialization of the drive and the “USB Out” button will change to green, displaying “USB
Eject”. To eject the USB Drive, touch the button with the wand. When the button turns gray and displays
“USB Out” it is safe to remove the USB Drive from the port.
“Reset” will clear alarms that have been set as latching after the alarm condition has passed. This will only
work when alarms have been set as “Latching”, and only after the alarm condition has been cleared.
“Alarm History” is a select button that will open the “Alarm History Screen” (Section 5.3).
“System Configuration” is a select button that opens the “System Configuration” Screen (Section 4.3).
880R-N4X Instruction Manual Rev. 0.0 Page 12 of 16
880R-N4X
5.2 Channel X Details Screen
When selected, each channel will open its own detail screen (Figure 22). This screen provides a graphic
representation of the last 30 minutes of the sensor’s activity. The display allows the user to move forward or
backward in the graphic to display activity before or after the displayed time using the arrow keys in the upper
left of the graphic display.
Figure 22 Channel Details Screen
When the sensor goes into a fault or alarm condition the “Current Conditions” box will highlight and blink the
associated fault(s) or alarm(s). Each fault or alarm has a different color for ease in dissociating the condition.
These conditions will remain highlighted and blinking until the conditions to correct them are met. I.E., a
‘CAL’ fault will not clear until the sensor returns to normal operation and, if set to non-latching and ascending,
Alarm 1 will not clear until the “Concentration” falls below the set “Alarm 1 Level.”
5.3 Alarm History Screen
Figure 23 Alarm History Screen
880R-N4X Instruction Manual Rev. 0.0 Page 13 of 16
880R-N4X
When alarms are initiated, the unit stores information about these alarms into memory. If a USB Drive is
installed in the back of the display, this information is written onto the drive for permanent storage (USB
Drive sold separately). The information can also be viewed on the “Alarm History Screen” by using the wand
to select the “Alarm History” button on the Main Screen.
The Alarm History Screen displays Fault and Alarm events throughout operation of the unit (Figure 23).
Navigation buttons located at the bottom of the page allow the user to view all logged data. The view can be
changed from Alarm History to Alarm Count, with a detail button that allows viewing more information on
each event recorded.
