A complete listing of a sample ladder logic program is included
at the back of this manual.
Examples shown here are for reference.
All values are 0 (default) on initial start-up.
This means that all alarms are disabled.
You must make the following adjustments for proper operation:
Balance sensor input(s)
Set Calibration numbers
Follow Steps 1 and 2 for each channel.
Step 1. Balance Sensor Input Check
1. Set to CAL mode.
2. Set Clear Tare bit momentarily.
3. Check Raw A/D value. (Range 2,090,000 to 2,100,000)
CH1 = Controller Tag HM1734WM1-a[2]
CH2 = Controller Tag HM1734WM1-a[5]
4. Set Zero Tare bit momentarily.
Step 2. Set Calibration Numbers
1. Set Scale to capacity of load cell.
2. Set mV/V to load cell specification.
Example:
100 ton load cell, 2.025 mV/V
For scale set, enter 100
For mV/V set, enter 2.025
3. Set to RUN mode.
