threshold will be set at 5% of channel rating. However, on some
machines clutch and brake engagement can cause forces in the
machine frame greater than this threshold, resulting in nuisance
tonnage readings. For this reason the threshold can be adjusted up
to 10% in the THRESHOLD screen as shown below.
While the keyswitch is in the PROG position the threshold will
flash, indicating that it can be changed. To increase or decrease
the threshold press the up or down arrow keys respectively.
2.8.5 CAM ZERO
CAM ZERO (zeroing by position) enables an external rotary cam
switch or limit switch to control the System 1100 zero circuits.
When CAM ZERO is enabled, the zero circuits are no longer
controlled by the zeroing threshold but instead by the closure of
the external cam switch. The CAM ZERO screen is shown below.
While the keyswitch is in the PROG position the ON or OFF indicator
will flash, indicating that it can be changed. To enable or
disable the use of the external zeroing cam, press the ON or OFF
keys respectively.
2.8.6 DATA WINDOW
The DATA WINDOW option in the Config menu allows the user to
completely disable the use of data windows. If data windows will
never be used, it is recommended that they be disabled in this way.
Disabling data windows simplifies some menu operations. In
particular, disabling data windows eliminates the DISPLAY option in
the Main menu. Also, when the SETPOINTS option is selected in the
Main menu, the operator is immediately shown the peak setpoints
instead of having to select from a list of the peak and data window
1, 2, 3, and 4 setpoints.
