7.2.3.Connection between FGV and PC
Please be sure to connect 5pin into 4 pin of digital GND when
making cable for RS-232C on your own. It cannot be transmitted
without this connection.
7.3.Analog output
Output ±1V for display range.
Output plus voltage when measuring value is plus (when compressing) and minus voltage when measuring value is minus (when
tensioning). Output will be nearly 0 V if you press ZERO key and tare.
Output signal ±1V (±Range which display is possible)
Signal method
12 bit D/A convertor method
Output update
1000 times/second *
Load resistance
10 kΩ or more
Output accuracy
±50mV
The analog output has a default update rate of 1000 times/second. The
output voltage is linearly scaled so that the current zero point of the
gauge corresponds with 0V, and so that 1V corresponds with 100% of the
gauge's reated capacity. This means that the tare function, or any change
in the gauge's zero point, will change the maximum voltage shown before
the gauge is overload.
When using analog cable (option), please plug
the connector side of cable into connector for
data output port of FGV and connect red banana
plug into plus and black banana plug into minus.
7.4.Overload/Comparator output
Output overload/comparator signal.
Switch of output overload/comparator signal is set by external output setting (f06) function mode.
Maximum allowance voltage DC 30V / current 5mA
Please connect the power and load to avoid going over maximum allowance.
• 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 prevent damage from accidental overload.
When compression overload occurs photo-couple 1 (PC1) turns on, and allows current to flow between Pin 8 and 10.
When tension overload occurs photo-couple 2 (PC2) turns on, and allows current to flow between Pin 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 regarding the activation and setting of comparator limits.
