Table 1-1. Display Items
NOTE: Totalizer data is held in the SCT-4XD memory. Totalizers may be reset using the Reset Totalizer buttons. System will prompt for confirmation of the reset.
Setup
When entering the Setup menu, the 1280 HMI uploads the current SCT-4XD configuration.
IMPORTANT: No data is stored at the 1280 HMI level.
The Setup menu is structured the same as the SCT-4XD on-board Setup menu except for:
- Password Setup: Passwords are only used or maintained at the 1280 HMI level.
- Test Weight Calibration: Part of the SCT-4XD User menu.
- Communication Menu: The 1280 HMI does not have access to the SCT-4XD Communication menu.
- Default: The 1280 HMI does not have access to the SCT-4XD Default menu.
Password Setup
The Password Setup menu allows password setup for restricted access to:
- Setup Menu
- Totalizer Resets
- Zero Calibration
- Test Weight Calibration
Initial Settings
The Initial Settings menu allows toggling between the following settings:
- Unit systems: Metric or US
- Operative mode: Belt or BulkSlide
Figure 2-3. Initial Settings Display
IMPORTANT: The SCT-4XD does not update its configuration settings until the 1280 HMI exits the Setup menu.
If the Initial Settings are changed, exit the Setup menu so the settings are transmitted to the SCT-4XD before proceeding to other configuration settings.

IMPORTANT: The SCT-4XD does not update its configuration settings until the 1280 HMI exits the Setup menu.
If the Test Weight Calibration settings are changed, exit the Setup menu so the settings are transmitted to the SCT-4XD before proceeding to other configuration settings.
Alarm Settings

Calibration
Test Weight Calibration
IMPORTANT: At a minimum, the following settings must be properly configured to match your weigh frame and conveyor specifications before performing calibration.
Configure the following parameters:
- Initial Settings: Select Metric or US (see Section 2.2 , Save and Exit before making other changes to configuration)
- General Parameters: Configure Encoder (if present, see Section 2.3)
- Belt Parameters:
- Enable Encoder (if present)
- Configure Encoder Pulse Length (if encoder is used)
- Configure Fixed Belt Speed (if no encoder is used)
- Calibration Parameters (see Section 2.6 ):
- Configure the number of load cell channels to the correct number
- Capture Static Zero by entering Zero mV value or capturing Zero mV value with the SCT-4XD Digitizer
- Configure Weigh Length
- Configure Load cell Capacity
- Configure Load cell Sensitivity
- Configure Belt Length if encoder is used
- Configure Belt Zero Time if encoder is not used
- Test Weight Calibration:
- Configure Test Weight Value
- Configure Test Distance (if encoder is used)
- Configure Test Time (if encoder is not used)
- Save and Exit the Setup Menu before proceeding to calibration
Perform the following to calibrate:
- From the Main Operating Screen, with the belt running at zero load, press the Zero Calibration button.
Figure 3-1. Zero Calibration Button - Select YES to perform a Zero Calibration.
Figure 3-2. Zero Calibration Confirmation Prompt - Wait for Zero Calibration to complete.
Figure 3-3. Zero Calibration Progress Bar - Hang or put test weights on the belt scale weighframe.
- Enter Setup Menu and press Test Weight Calibration button.
Figure 3-4. Test Weight Calibration Button - Select YES to start a test weight calibration.
Figure 3-5. Test Weight Calibration Confirmation Prompt - Wait for Test Weight Calibration to complete.

BulkSlide Calibration
IMPORTANT: At a minimum, the following settings must be properly configured to match your BulkSlide device specifications before performing calibration.
Calibrate the following:
- Initial Settings (see Section 2.2):
- Select Metric or US (Save and Exit before making other changes to configuration)
- Select BulkSlide (Save and Exit before making other changes to configuration)
- Calibration Parameters (see Section 2.6 ):
- Capture Static Zero by entering Zero mV value or capturing Zero mV value with the SCT-4XD Digitizer (see the Zero Scale section in the SCT-4XD Technical Manual for further instructions)
- Configure Load cell Capacity
- Configure Load cell sensitivity
Perform the following to calibrate:
- Perform Step 1 through Step 3 of the Test Weight Calibration Procedure to capture the Dynamic Zero.
- Select the Reset Totalizer 1 button.
- Confirm the reset request.
- Process the same material through the BulkSlide at least 3 times, using Totalizer 1 to ensure repeatability. Clear Totalizer 1 after each run.
- Post-weigh or pre-weigh the amount of material and record the Totalizer 1 value.
- Use the following formula to calculate the new Correction Factor using the Weight of the material and the recorded Totalizer 1 value.
New Correction Factor = (Actual Weight of Material/Displayed Weight of Material) x previous Correction Factor - In the Setup menu under Calibration Parameters, enter the New Correction Factor in the Correction factor field.

Analog Output
The 1280 HMI can transmit the SCT-4XD flow rate out of an analog output card assigned to any available slot.
- Set Source to Programmability
- Set Maximum Value Tracked to the Max Flow Rate of the SCT-4XD
