1280 Enterprise Series
Single A/D Scale Card Installation
The Single A/D Scale Card (PN 164085) provides a single scale channel. The 1280 can support up to eight scales. The
configuration of each scale is stored both on the card and in the indicator’s memory. The CPU board will rewrite the calibration
to the A/D scale card when replacing or swapping installed cards.

21280 Single A/D Scale Card Installation
Always disconnect power before opening the indicator. Option card is not hot swappable.
Use a wrist strap to ground yourself and protect components from electrostatic discharge (ESD) when working
inside the indicator enclosure.
1. Open the indicator as instructed in the 1280 technical manual.
2. Remove a slot cover plate from the controller assembly to open a slot for the card.
3. Remove protective tape from pins J3 on the option card prior to installation. Make sure the pins are clean of sticky
residue by carefully wiping with a cloth dampened with rubbing alcohol.
4. Ensure S1 switch on the card is in the Run position (Figure 2).
5. Align the card to the slot; the screw hole in the faceplate of the card should align with the screw hole on the controller
assembly.
6. Slide the card into the top and bottom grooves of the slot. Push the card until it is securely seated in the back plane.
7. Secure with screw 4-40 NC x 1/4 (provided).
8. Route the cable through the cord grip to attach the cable from the scale to the A/D scale card.
9. Wire the load cell cable from the scale to the connector (from the parts kit) for J1 as shown in Figure 2 and Table 3.
To use a 6-wire load cell cable (with sense wires), remove jumpers JP1 and JP2 before installing cord to J1. To use a
4-wire connection, leave jumpers JP1 and JP2 on.
10. When connections are complete, install load cell connector on the A/D scale card.
A sealing clip can be installed over the connector to provide a hardware seal that allows access while preventing
removal of the scale card and connector.

Addendum 3
The slot of the controller assembly selected for the installation of the card determines the scale channels that can be
associated to a scale number.
Slot 1 = Slot 1 Channel 1
Slot 2 = Slot 2 Channel 1
Slot 3 = Slot 3 Channel 1
Slot 4 = Slot 4 Channel 1
Slot 5 = Slot 5 Channel 1
Slot 6 = Slot 6 Channel 1
11. Use cable ties from the parts kit to secure loose cables inside the enclosure as needed. Ensure no excess or loose
cable is left inside the enclosure.
12. Ground the shield cable using the ground washer in the metal cord grip, or the grounding stud on the enclosure using
cable clamp included in the parts kit. See the 1280 technical manual for more information.
13. Tighten cord grips. Ensure cord grip nut is also tight.
14. Reassemble and power the indicator.
15. Press on the weigh mode screen. The Main Menu displays.
16. Press for access to the Configuration menu.
Access to the Configuration menu may be restricted. Refer to the 1280 technical manual for more information.
17. Select to enter the scales menu and configure the single A/D scale card.
18. Select the scale number (1-8) to be configured from the selection field drop down list.
19. Select and set the scale to Analog Load Cell Scale. The Select Scale Hardware screen displays.
20. Select the slot and channel desired.
21. See the 1280 technical manual for calibration instructions.
