1.2 Operating Modes
The 880 has three modes of operation:
Normal mode
Normal mode is the weighing mode of the indicator. The indicator
displays gross or net weights as required, and annunciators to indicate
scale status and the type of weight value displayed.
Setup mode
Most of the procedures described in this manual require the indicator to
be in setup mode, including configuration and calibration.
To enter setup mode, remove the fillister head screw from the enclosure
backplate. Insert a screwdriver or a similar tool into the access hole and
press the setup switch once. The indicator display changes to show the
word CONFIG.
The 880 also has an Audit Trail that can track changes to configuration
and calibration, allowing the setup switch to be bypassed with Jumper J5
on the CPU board.
User Setup Mode
User setup mode (accessed by pressing the MENU key) is used
• View the audit trail
• Set the time and date
• Access the accumulator
• Change setpoint values
See Section 1.4.8 for more information about entering user setup mode.
1.3 Front Panel Display
Figure 1-1 shows the 880 front panel keys and the key functions assigned in normal
mode.
The numeric display consists of six large, 14-segment LED digits. If a negative
number is displayed the first LED is used to display “-”, reducing the number of
available digits to five.
The symbols on the keys in Figure 1-1 (representing up, down, enter, left, right)
describe the key functions assigned in setup mode. The keys are used to navigate
through menus, select digits within numeric values, and increment/decrement values.
See Section 3.1.3 for information about using the front panel keys in setup mode.

conditions for standstill are met. PRINT may be displayed while the unit
prints.
Also used to navigate to different menus or to toggle to another digit when
editing a value.
Toggles between gross and net. If a tare value has been entered or
acquired, the net value is the gross weight minus the tare.
Gross mode is shown by the Gross/Brutto annunciator; net mode is
shown by the Net annunciator.
Also used to navigate to different menu levels or to decrement a number
when editing a value.
The MENU key is used to access the setup menu.
Also acts as the cancel key when editing parameter values.
Switches the weight display to an alternate unit, defined in the Format
menu, see Technical/Service manual for more information.
Units Available: lb, kg, oz, metric ton, ton, gram.
Also used to navigate to different menus or to toggle to another digit when
editing a value.

Installation 12
2.0 Installation
This section describes procedures for connecting load cells, digital I/O, and serial
communications cables to the 880 indicator. Instructions for replacement of the CPU
board are included, along with assembly drawings and parts lists for the service
technician.
• Use a wrist strap to ground yourself and protect components from electrostatic
discharge (ESD) when working inside the indicator enclosure.
• This unit uses double pole/neutral fusing which could create an electric shock
hazard. Procedures requiring work inside the indicator must be performed by
qualified service personnel only.
• The supply cord serves as the power disconnect for the 880. The power outlet
supplying the indicator must be installed near the unit and be easily accessible.
2.1 Unpacking and Assembly
Immediately after unpacking, visually inspect the 880 to ensure all components are
included and undamaged. The shipping carton should contain the controller, display,
Operator's manual, CD and parts kit. If any parts were damaged in shipment, notify
Rice Lake Weighing Systems and the shipper immediately.
2.2 Panel Mount Installation
The controller can be mounted to the display DIN rail or mounted
remotely up to 250 ft away from display.
Figure 2-1. 880 Panel Mount Dimensions
Use the Din Rail mount plate as a template (see Figure 2-2) to drill the mounting
holes in the panel for the stainless steel panel mount enclosure.
See Figure 2-1 for enclosure dimensions.

6. Secure to DIN rail by rotating the left and right hooks up connecting with the
bottom rail.

2.2.1 Mounting the Controller Assembly Remotely
To mount the controller assembly remotely a 6 pin connector (PN 153885) is
required. See Figure 2-5 for terminal location and pin assignments.
Controller Assembly can be mounted remotely on a standard 35 mm DIN
rail up to 250 ft from display.

2.3 Cable Connections
The 880 has three external connectors, a terminal connector for the power cord, and a
cutout for installed options. Enclosure disassembly is not required to make
connections to load cells, communications, digital inputs, and digital outputs. These
connectors are all externally mounted on the back of the controller.
2.3.1 Load Cells
To attach cable from a load cell or junction box, route the cable to the external
J1connector. Wire the load cell cable from the load cell or junction box to connector
J1 as shown in Table 2-1. If using 6-wire load cell cable (with sense wires), open the
unit and remove jumpers JP5 and JP6.
For 4-wire installation, leave jumpers JP5 and JP6 on (see Figure 2-7).
Shield wire will attach to ground clamp on backplate.
2.3.2 Power Connections
Power connections to the 880 Panel Mount are shown below.
• Part number 152334 is used to connect AC power to the power supply board.
• Part number 15888 is used to connect DC power to the power supply board.
Attach the wires per the diagram shown below.

2.3.3 Serial Communications
Connector J3 provides connections for the RS-232 or the two-wire RS-485. Table 2-2
shows the pin assignments.
For RS-232, all four switches on SW3 (see Figure 2-7) must be in the OFF
position.
For RS-485, all four switches on SW3 must be in the ON position.
2.3.4 USB Device Communications – Port 2 (USBCOM)
The USB Device Port is intended to be connected only to a PC. It will appear as a
Virtual Comm Port and be assigned a “COMx” (J4 micro USB connector, see
Figure 2-6) designation. Applications will communicate through the port like a
standard RS-232 communications port. See Technical/Service Manual for more
details.
2.3.5 USB Host Device
Not available at time of publication.
2.3.6 Ethernet Communications
The 880 supports Ethernet TCP/IP 10Base-T/100Base-TX communications using a
standard RJ45 connector (J6 – see Figure 2-6). Through the network, software
applications are able to communicate with the 880 using the EDP command set. See
Technical/Service Manual for more details.

Connectors
The Comm 1 port supports RS-232 or RS-485 communications; selectable with
switch SW3. The port is configured using the COM menu under Ports. See
Section 3.2.5.
2.5 Audit Trail and the Audit Jumper
The 880 includes an audit trail feature that keeps track of the number and the last date
of calibrations and Legal-for-Trade configuration changes. It is possible to setup the
880 to allow entry to the configuration and calibration menus using only the front
panel MENU key.
On the top of the CPU board is a 3-pin Jumper (JP4 - see Figure 2-7) that enables or
disables this feature.
• To use the audit trail and allow the use of the MENU key to enter the
configuration and calibration mode, place the jumper in the ON position.
• To prevent the use of the MENU key to enter the configuration and
calibration mode, instead requiring use of the externally sealable
configuration switch located inside the enclosure (see Figure 3-1), place the
Jumper in the OFF position.
The audit trail counters will operate in either position of the audit jumper.
