Problem Possible cause Investigation method Countermeasure
Incorrect power
supply
Check if the power supply voltage
is within the range of 12 to 24 VDC.
Supply power supply voltage
of 12 to 24 VDC.
8
Indicated values
fluctuate.
Incorrect wiring
Check the wiring to the power
supply.
Check if the brown and blue wires
are connected to DC(+) and DC(-)
respectively and if the output line is
about to come off (contact failure).
Correct the wiring.
Incorrect power
supply
Check if the power supply voltage
is within the range of 12 to 24 VDC.
Supply power supply voltage
of 12 to 24 VDC.
Power saving
mode
Check if the power saving mode is
selected.
Reset the setting of function.
9
Indicator turns
off.
A part of the
indication
misses.
Product failure Replace the product.
The peak
value/bottom
value indication
mode is
selected.
Check if the peek value or bottom
value indicating mode is selected.
Turn off the peak
value/bottom value indication
mode.
10
Indicator is
blinking.
Wiring failure
(1)Check the power supply wiring.
(2)Check if bending stress is being
applied to a specific part of the
cable.
(1)Correct the wiring.
(2)Correct the wiring (bending
radius and stress).
Dispersion within
the indication
accuracy range
Check if the dispersion is within the
indication accuracy range.
Use the fine adjustment mode
to adjust the indication if the
dispersion is within the
indication accuracy range.
11
Pressure indication
difference when
using two or more
Pressure switches.
Product failure Replace the product.
Foreign matter
Check if foreign matter has entered
the pressure port.
Install a 5 m filter to prevent
foreign matter from getting into
the pressure port. Also, clean
the filter regularly to prevent
drainage deposits.
Air and liquid
leakage
Check if air and liquid are leaking
from the piping.
Rework the piping.
If excessive tightening torque
over the specified range is
applied, a mounting screw,
mounting bracket, and product
may be broken.
Insufficient
warm-up
Check if the product satisfies the
specified accuracy 20 minutes after
supplying power.
After energizing, indication
can drift. For detecting fine
pressure, warm up the product
for 20 to 30 minutes.
12
The pressure
indication
accuracy does
not satisfy the
specifications.
Product failure Replace the product.
