•Over current
error (Er1,2) is
displayed.
•COPY receiving
error (Er13) is
displayed.
•System error
(Er0, 4, 6, 7, 8,
14,40) is
displayed.
•"HHH" is
displayed.
•"LLL" is
displayed.
Excess current
was applied to
the output (Er1,2)
(1) Check if the output current is 20
mA or more.
(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.
Copy function
operated
incorrectly (Er13)
Check the wiring.
Check if the brown and blue wires are
connected to DC(+) and DC(-)
respectively and the grey wires to
each monitor are connected, and that
the wiring is secure.
Correct the wiring.
Incorrect internal
data processing
of the product
(Er0,4,6,7,8,14,4
0)
(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 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 and then turn back on
the power supply.
(2) Supply power in the
range 12 to 24 VDC
±10%.
Applied flow is
higher than the
upper limit (HHH)
(1) Check if the flow exceeds the
upper limit of the set flow range.
(2) Check if foreign matter has
entered the piping.
(1) Reset applied flow to a
level within the set flow
range.
(2) Take measures to
prevent foreign matter
from entering the piping.
Applied flow is
lower than the
lower limit (LLL)
(1) Check if the flow exceeds the
lower limit of the set flow range.
(2) Check if foreign matter has
entered the piping.
(1) Reset applied flow to a
level within the set flow
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 12 to 24 VDC ±10%.
Supply power in the range
12 to 24 VDC ±10%.
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 flow is stable.
Improve the display stability
by setting the delay time or
digital filter.
