4-1-1-2. Strain Gauge Sensor Connection
Before connecting a sensor, set the excitation voltage, turn off the power, and perform
the following connection. (See "5-6. Excitation Voltage" P34.)
・4-wire sensor
・ 6-wire sensor
For connecting a 6-wire strain gauge type sensor, short-circuit +EXC and +S, and -EXC
and -S.
・ For connecting a sensor, be sure to use shielded lines, and separate
wiring from lines with heavy noise (such as wiring of power equipment
and wiring of digital equipment) and AC lines.
・ The analog GND in the F395 is grounded to F.G. Also, when voltage/
current input is specified, the -SIG terminal is at about the same level
as the analog GND. (See "20. Block Diagram" P152.) Carry out wiring
so that unnecessary current will not flow.
