Setting Machine Capacity Scale for multiple channel systems.
Divide the Machine capacity by the number of sensors and set Machine Capacity Scale on all modules to the result.
Example: If 2 load modules are used for monitoring a straight side press with 4 sensors mounted on the press columns,
set the Machine Capacity Scale on both modules to the highest load/tonnage of one sensor.
Use the following table as a reference for setting the Machine Capacity Scale for a system comprised of (2) force modules
and (4) sensors.

Step 5. Set Capacity Alarms
This value is a discrete load/tonnage value, not a percentage.
NOTE: Although the range of values for capacity alarm settings is 0 to 9999, it is recommended that you do not enter
values that exceed the capacity rating of the machine/press. A value of 0 disables capacity alarm set.
To determine the maximum rating for each channel, divide the total machine/press capacity by the number of sensor
inputs. EXAMPLE: A press or slide rated at 100 tons with a (2) channel force module would have a capacity alarm
setting of 50 tons per sensor input.
This setting differs from the Scale setting as it can be adjusted up or down depending on the nature of the process.
The recommended maximum value is 195% of Machine Capacity Scale.
