Error Troubleshooting
No outputs
Check the power supply.
Check the polarity (+, -) when wiring cable.
Check the connection part.
Abnormally uctuating output
Check the power supply.
Check the supplied pressure.
Check the pressure line.
Out of zero point output value
Check the power supply.
Check the load resistive value of current output type for a receiver is over 600Ω.
Check the measuring point and transmission distance.
Check the line resistance is below 600Ω.
•When installing the unit on pipe line, use t he hexagon
part of connections not to turn the unit with a pipe
wrench. Do not use the unit with strong vibrations.
•This unit is manufactured with precisely. If you drop or
shock the unit, it may lose the function. Please treat the
unit carefully.
•Store the unit at the place without moisture, dust, and
vibration.
•This product which does not have drive part at sensing
part does not need to repair it. Even though inside
of pressure pipe is normally clean, it needs to take
maintenance once a year as below instructions.
①Check the broken status of outside.
②Check the pressure slot, cleanliness inside, and
corrosion state.
③Short each terminal and check the insulation
resistance between the case and power.
(at 100VDC, over 10MΩ)
④Check zero, span adjustment and linearity by
pressure standards.
•When removing a sensor for maintenance, follow the
below instructions.
①Replace an O-ring which is used once.
②Be sure that diaphragm part is not damaged.
•In case of head type for connecting the power, use a
crimp terminal. (M3.5, max. 7.2mm)
•The connection of this unit should be separated from
the power line and high voltage line in order to prevent
inductive noise.
•Install a power switch or a circuit breaker to supply or
cut off the power.
•Connect the power with the crimp terminals.
•Switch or circuit breaker should be installed nearby
users for convenient control.
•Do not use the unit near the high frequency instruments
(high frequency welding machine & sewing machine,
large capacity SCR controller).
•The unit cannot be repaired due to disassembled
structure.
•The unit is xed with bolt and nut at the both sides of
case. Do not press excessive load (approx. 300kg/cm2),
or it may cause damage to the unit.
•Do not pull the cables with over 30N of tension force.
•Tighten the cable connection part rmly not to enter
water to the cable.
•This product may be used in the following environments.
①Indoor / Outdoor
②Altitude max. 2,000m
③Pollution degree 2
④Installation category II
