2.2 LCD Display
Note: The default setting for the four digit displays shows compression
loads as a positive force and tension loads as a negative force. to
reverse these settings, showing compression loads as negative and
tension loads as positive, see section 4.1 for setting f01.

Overload Output
When the overload condition is triggered, the corresponding overload output
turns on. this can be used to stop a motorized test stand, or an alarm to pre-
vent damage from accidental overload.
When compression overload occurs photo-couple 1 (PC!) turns on, and
allows current to flow between pins 8 and 10.
When tension overload occurs photo-couple 2 (PC2) turns on and allows
current to flow between pins 9 and 10.
If no overload condition exists, PC1 and PC2 should be closed and will not
allow current flow.
Overload occurs at about 120% of the gauge’s rated capacity. this includes
any weight zeroed during any tare operation.
Comparator Output
When the LO limit is reached, photo-couple 1 (PC1) turns on and allows
current to flow between pins 8 and 10.
When the HI limit is reached, photo-couple 2 (PC2) turns on and allows
current to flow between pins 9 and 10.
Refer to section 7 regarding the activation and setting of Comparator
limits.
