1.0 Introduction
The 1280 Enterprise Series is a color touchscreen, programmable, multi-channel digital weight indicator/controller.
Manufactured with industrial-grade components, the 1280 is built to achieve top performance, even in harsh environments. The
1280 features a Freescale i.MX6 microprocessor, Linux-based operating system and 1 GB onboard memory (expandable with
micro SD card). Configuration can be performed using the front panel, serial commands or Revolution®scale software.
For applications using the 1280 indicator as a host device, Version 1.03 or later of the 1280 indicator software must be installed.
Custom programs can be written with iRite®, a domain-based programming language based off of Basic, Pascal and Ada—
empowering programmers to customize display widgets, store and retrieve data with the onboard database and utilize the 150+
built-in-functions. From tailored basic weighing to complex process automation, the 1280 delivers uncompromising speed for
today’s most demanding applications as well as vast expandability for future needs.

2.0 Installation
This section describes procedures for connecting power, load cells, digital I/O and data communications cables to the 1280
indicator. Instructions for replacement of the circuit boards are also included, along with assembly drawings and replacement
parts lists for the service technician.
WARNING
Failure to heed the following statements could result in serious injury or death.
* Use a wrist strap for protection and damage to components from electrostatic discharge (ESD) when working
inside the indicator enclosure.
* Procedures requiring work inside the indicator must be performed by qualified service personnel only.
* In the wall and universal mounts, the supply cord serves as the power disconnect. The power receptacle to the
indicator must be accessible for these models.
2.1 Unpacking
Immediately after unpacking, visually inspect the 1280 to ensure all components are included and undamaged. The shipping
carton should contain the controller, display, CD, parts kit, any options ordered with the unit and the appropriate manuals. If any
parts were damaged in shipment, notify Rice Lake Weighing Systems and the shipper immediately.
2.2 Mounting/Assembly
There are three enclosure styles – universal mount, wall mount and panel mount.
2.2.1 Universal Mount Enclosure with Tilt Stand
The universal mount is shipped with a tilt stand and can be mounted on a wall, tabletop or any flat surface.
Figure 2-1. Mount Universal Enclosure
1. Using the tilt stand as a template, mark the screw locations. See Figure 2-5 on page 5 for dimensions.
The universal enclosure can mount to the same location where a 920i universal enclosure was mounted; the screw
locations for the tilt stand are the same.
Note
2. Drill holes for the screws.
3. Mount the tilt stand using the appropriate hardware (not included).
4. Place one washer on each side stud of the indicator enclosure.
5. Place the indicator side studs into the holes on the arms of the tilt stand.
6. Secure with remaining washers and hand knobs from the hardware kit.
7. Wire the indicator. See Section 2.4 on page 16.

Remove Shipping Bracket
The universal mount is shipped with a shipping bracket inside the enclosure to stabilize it during shipping.
1. Loosen the four screws securing the front door.
Figure 2-2. Remove Shipping Bracket
2. Pull the door and fully extend the hinge to swing the door open.
3. The bracket is loose, remove it from the enclosure.
Note
Retain shipping bracket for future shipping needs.
Controller Disassembly
Note
The controller can be tilted up with the locking tab or it can be completely removed from the enclosure by removing
the retaining wire bail.
1.Remove the large fillister screw in the back of the indicator to tilt or remove the controller. The seal must be
broken for this purpose.
Figure 2-3. Open Cover
2. Loosen the four screws securing the front door.
3. Pull the door and fully extend the hinge to swing the door open.
4. Pull the locking tab to the left to release the controller assembly.
5. Remove the wires connected to the controller assembly.
6. Remove the retaining wire bail connected to the controller assembly. This only needs to be removed if the controller is
being removed from the enclosure.
7. Lift controller assembly from the enclosure.
Reverse this procedure for reassembly. Upon reassembly, ensure display and keyboard wires are properly connected.
Note
To close the door to the universal enclosure, push the bail in and down so that it does not get caught on the
controller assembly.

Sealing the Setup Switch
In certain Legal for Trade applications, it may be necessary to seal the indicator to restrict access from the setup switch. Use
the following instructions to seal the universal enclosure.
IMPORTANT
The audit trail jumper (JP1) needs to be disabled, in the off (right) position, in order to seal the setup switch with
a lead seal wire. Access is not prevented simply by sealing the setup switch.
1. Turn the audit trail jumper (JP1) to the right to turn off. See Section 2.7 on page 22 for instructions on how to remove
the CPU board (which is necessary to disable the audit trail jumper). This restricts access from the configuration menu
through the front panel.
2. If not previously installed, install the large fillister screw in the back of the indicator.
3. Wrap the lead wire seal through the large fillister screw and the two smaller fillister screws in order to seal the
indicator. This will restrict access to the setup switch.

IMPORTANT
The audit trail jumper (JP1) needs to be disabled, in the off (right) position, in order to seal the setup switch with
a lead seal wire. Access is not prevented simply by sealing the setup switch.
Wrap the lead wire seal through the large fillister screw and through the bottom tab of the DIN rail clip to restrict access to the
setup switch. Alternatively, the A/D scale card includes fillister screws and a bracket that prevent the load cell cable from being
disconnected.

2.3 Option Card Installation
Use the following instructions to install option cards. There are two SPI communication buses for the six option card slots: one
for slots 1, 2 and 3 and one for slots 4, 5 and 6. Communication is faster with less traffic on an SPI bus. For optimal
performance, populate slots 1 and 4 first in order to keep cards on their own SPI bus.

Note
Figure 2-25 on page 15 illustrates label location.
WARNING
Failure to heed the following statements could result in serious injury or death.
Note
* Use a wrist strap for protection and damage to components from electrostatic discharge (ESD) when working
inside the indicator enclosure.
* Procedures requiring work inside the indicator must be performed by qualified service personnel only.
* In the wall and universal mounts, the supply cord serves as the power disconnect. The power receptacle to the
indicator must be accessible for these models.
* Option cards are not hot-swappable. Disconnect power to the indicator before installing option cards.
It is recommended to remove the controller assembly from the universal enclosure for easier installation of the
option cards. See Section 2.2.1 on page 3.
1. Remove the hardware securing the slot cover plate.
2. Remove the slot cover plate.
3. Slide the option card into place.
4. Secure the card using the hardware that secured the slot cover plate.
5. Connect cables. See Section 2.4 on page 16.

Seal the Scale Card
Once an option card has been put into place and cable connections have been made, a seal can be placed over the card and
connections to restrict access and keep them from being removed.
Figure 2-26. Seal Option Card
1. Align the sealing bracket over the connectors on the option card.
2. Secure with two fillister screws.
3. Insert the lead wire seal through the holes in the sealing bracket and the fillister screws.
2.4 Cable Connections
The universal and wall enclosures provide cord grips for cabling into the indicator; one for the power cord and the rest are to
accommodate interface cables. Install plugs in unused cord grips to prevent moisture from entering the enclosure. Secure wires
after cabling is complete to avoid low voltage circuits contacting high voltage circuits.
2.4.1 Grounding Through Cord Grips
To ground cables to the universal or wall enclosures, route the cable through one of the metal cord grips. Ensure the exposed
shielding makes contact with the tabs of the grounding washer inside the cord grip.

Note
Ensure contact between the exposed shielding and the tabs of the grounding washer.
