Troubleshooting

Error Troubleshooting
Do you supply the power?
No outputs Do you wire (+, -) it correctly?
Is the connection part poor?
Is power supplied properly?
Abnormally fluctuating output Is pressure supplied correctly?
Is there error in pressure line?
Is power supplied properly?
Is the load resistive value of a receiver over 600Ω?
Out of zero point output value
Is the measuring point and transmission distance proper?
Is line resistance big? (max. 600Ω)

•• When removing a sensor for maintenance, follow the

belows.
① Replace an O-ring which is used once.
② Be sure that diaphragm part is not damaged.
•• In case of head type for connecting the power, use a
crimp terminal(M3.5, min. 7.2mm).
•• The connection of this unit should be separated from
