Rice Lake 880 Performance Series User manual

880 Performance™ Series
Relay Option Card Installation
The Relay Option Card provides four normally open relays for an 880 indicator when installed. The Relay Option Card attaches
to the 880 CPU board. Depending on the desired output of the Relay Option Card, SLOT 1 must be configured in the Setpoints
Menu (SETPTS) and BIT 1-4 in the Digital I/O Menu (DIGIO) within the Setup Menu of the 880 indicator. Refer to the 880
Technical Manual (158387) for additional information on the configuration of relays.
The indicator automatically recognizes all installed option cards when the unit is powered on. No hardware-specific
configuration is required to identify an installed option card to the system.
Manuals and additional resources are available from the Rice Lake Weighing Systems website at www.ricelake.com
Warranty information can be found on the website at www.ricelake.com/warranties
Always disconnect power before opening an enclosure or controller assembly. Option card is not hot swappable.
Procedures requiring work inside the indicator must be performed by qualified service personnel only.
A grounding wrist strap must be worn to protect components from electrostatic discharge (ESD) when working
inside an enclosure or controller assembly.

Panel Mount Installation
1. Disconnect power to the indicator.
2. Unhook the controller assembly from the front panel DIN rail by inserting a flat blade screwdriver into the bottom tab
and sliding the mounting plate down (Figure 2). Due to the angle of the hook portion of the DIN bracket, it may be a
little tight as it is disconnected.
Carefully separate the controller assembly from the front panel. The display cable harness still connects the
front panel to the controller assembly.
3. Disconnect the display cable harness from the controller assembly.
Figure 2. Front Panel and Backplate Removal
4. Remove the four screws securing the controller assembly backplate to the enclosure and carefully pull the backplate
straight out from the enclosure.
Removing the backplate from the enclosure voids the Legal for Trade status if enclosure is sealed.
5. Remove the two screws securing the power supply board to the backplate and carefully lay the power supply down.
Figure 3. Power Supply Board and Faceplate Cover Removal
6. Remove the two screws securing the option opening faceplate cover to the CPU board standoffs.
7. Carefully align the J5 connector on the bottom of the option card board with the J8 connector on the 880 CPU board.

Figure 4. Option Card Board and Faceplate Installation
9. Use three provided option kit screws to secure the option card board to the threaded standoffs on the 880 CPU board.
10. Use the remaining screw provided in the option card kit to secure the option card faceplate to the threaded mounting
block on the option card board within the option opening of the 880 panel mount backplate.
11. Reconnect the power supply board to the backplate with the two previously removed screws.
12. Slide backplate with boards into the controller assembly enclosure, ensuring that each board is seated correctly in the
grooves of the enclosure.
Before securing the backplate, verify the display connector aligns properly with the front cutout. If not aligned,
remove the backplate with boards and re-insert so the display connector aligns with the front cutout.
Figure 5. Backplate with Boards Reassembly
13. Secure backplate to controller assembly enclosure with the four previously removed corner screws.
14. Reconnect the display cable harness and then reconnect the controller assembly to the front panel DIN rail.
15. Connect necessary cable(s). See Connection Pin Assignments on page 5 for additional information.
16. Shield ground the cable(s) using a cable clamp, washer and nut provided in the option card kit and a grounding stud
on the controller assembly backplate.
See the 880 technical manual (158387) for additional information on shield grounding.
17. Reconnect power to the indicator.
18. If needed, see the 880 technical manual (158387) for additional information on Relay configuration.
SLOT 1 must be configured in the Setpoints Menu (SETPTS) and BIT 1-4 in the Digital I/O Menu (DIGIO) within the
