Problem
Possible cause
Investigation method
Countermeasure
Incorrect wiring
Check if the analog output line is
connected with a load.
Correct the wiring.
Non-compliance
with the load spec.
(1) Check if the proper load is
connected.
(2) Check if input impedance of input
equipment (A/D transformer) is
proper.
Connect a proper load.
Insufficient
warm-up
Check if the product satisfies the
specified accuracy in 10 minutes
after supplying power.
After energizing, indication and
output can drift. For detecting
fine pressure, warm up the
product for 10 to 15 minutes.
6
Analog output is
not provided.
(Specified
accuracy is not
satisfied.)
Product failure
Replace the product.
Over current to the
output
(Er1 and 2)
(1) Check if a current of 80 mA or
more is flowing to the output.
(2) Check if the connected load
satisfies the specifications, and if
the load is shorted.
(3) Check if a relay without a surge
voltage suppressor is connected.
(4) Check if the wiring is in the same
route as (or bundled together
with) a high-voltage line or the
power line.
(1)
,
(2) Connect the load as
specified.
(3) Use a relay with a surge
voltage suppressor or
take a measure to
prevent noise.
(4) Separate the wiring from
the high-voltage line
and/or power line.
Improper
transaction of the
internal data of the
Pressure switch
(Er0, 4, 6 and 7)
(1) Check if there is noise
interference such as static
electricity. Check if there is a
noise source
(2) Check if the power supply
voltage is in the range of 12 to
24 VDC ±10%.
(1) Remove the noise and the
noise source (or take
measures to prevent noise
interference), and reset the
product or turn off the
power supply. Then, supply
the power again.
(2) Supply power voltage of
12 to 24 VDC ±10%.
Applied pressure
is over the upper
limit (HHH).
(1) Check if the pressure gets over
the upper limit of the set pressure
range.
(2) Check if foreign matter got into
the piping.
(1) Bring the pressure back
within the set pressure
range.
(2) Take measures to prevent
foreign matter from getting
into the piping.
Applied pressure
is under the lower
limit (LLL).
(1) Check if the pressure gets below
the lower limit of the set pressure
range.
(2) Check if foreign matter got into
the piping.
(1) Bring the pressure back
within the set pressure
range.
(2) Take measures to prevent
foreign matter from getting
into the piping.
Pressure is not
atmospheric
pressure at
zero-clear
operation (Er3)
Check if the pressure over ±10%F.S.
(from the atmospheric pressure to
the upper limit of rated pressure) of
the atmospheric pressure is applied.
Return the applied pressure
to atmospheric pressure, and
retry the zero clear operation.
7
•
An over current
error (Er1 and 2)
is indicated.
•
System error
(Er0, 4, 6 and 7)
is indicated.
•
The display
shows "HHH".
•
The display
shows "LLL".
•
Residual
pressure error
(Er3) is
indicated.
Product failure
Replace the product.
