Excess current
was applied to the
output (Er1, 2)
(1) Check if the output current is 80 mA
or greater.
(2) Check if the connected load
complies with the specification.
Check if the load is short circuited.
(3) Check if the relay without surge
protection is connected.
(4) Check if the wiring is in the same
route as (or bundled together with) a
high-voltage or power line.
(1)(2) Connect the appropriate
load.
(3) Use a relay with a surge
voltage suppressor or take
measures to prevent surge.
(4) Separate the wiring from the
high-voltage and/or power
line.
Incorrect internal
data processing of
the product
(Er0, 4 to 16, 40)
(1) Check if there is noise interference
(such as static electricity).
Check if there is a noise source
nearby.
(2) Check if the power supply voltage is
in the range 21.6 to 30 V.
(1) Remove the noise and the
noise source (or take
measures to prevent noise
interference), and reset the
product (or turn off and then
turn back on the power
supply.
(2) Check that the Power supply
voltage is 21.6 to 30 V.
The measured
value exceeds the
upper limit (HHH)
or lower limit (LLL)
(1) Check if the value exceeds the upper
or lower limit of the set range.
(2) Check if foreign matter has entered
the piping.
(1) Return the value to within the
set range.
(2) Take measures to prevent
foreign matter from entering
the piping.
Product failure
Replace the product
The display is
unstable.
Incorrect power
supply
Check if the power supply voltage is in
the range 21.6 to 30 V.
Power supply voltage is 21.6 to
30 V.
Incorrect wiring
Check the power supply wiring
Check if the brown and blue wires are
connected to DC(+) and DC(-)
respectively, and if the wiring is secure
Check and correct the wiring.
Factory line
pressure is not
stable
Check if the factory line pressure is
changing.
Setting of the response time may
improve the condition.
