CHECKING
1) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal 7
– 8 with a multimeter.
3) Strain gauge: Maximum allowable current supplied to the
strain gauge is 30mA. Check the resistance of the sensor.
4) Input: Check voltage across the terminal 10 (+) – 11 (–)
with a multimeter. The voltage value at the maximum
load must equal [Excitation
×
Strain Gauge Sensitivity].
5) Output
• Open collector: Check that the output load is 30V DC/
30mA at the maximum. Saturation voltage is 1.1V DC.
Check the input threshold voltage (at L level) of the
connected device to be greater than that.
• CMOS level: Check the output voltage. (H
≥
4.5V DC, L
≤
0.5V DC)
