VII
(1) Do not use the product in the following locations.
• Locations subject to direct radiant heat from heating equipment
• Locations where the product may come into contact with water or oil
• Locations subject to direct sunlight
• Locations where dust or corrosive gases (in particular, sulfuric or ammonia gas) are
present
• Locations subject to extreme temperature changes
• Locations where icing or condensation may occur
• Locations subject to excessive shocks or vibration
(2) Do not use the product in locations subject to temperatures or humidity levels outside
the specified ranges or in locations prone to condensation. If the product is installed in a
panel, ensure that the temperature around the product (not the temperature around the
panel) does not go outside the specified range.
(3) Provide sufficient space around the product for heat dissipation.
(4) Use and store the product within the specified temperature and humidity ranges. If
several products are mounted side-by-side or arranged in a vertical line, the heat
dissipation will cause the internal temperature of the products to rise, shortening the
service life. If necessary, cool the products using a fan or other cooling method.
(5) The service life of the output relays depends on the switching capacity and switching
conditions. Consider the actual application conditions and use the product within the
rated load and electrical service life. Using the product beyond its service life may result
in contact welding or burning.
(6) Install the product horizontally.
(7) Mount to a panel between 1 and 8-mm thick.
(8) Use the specified size of crimp terminals (M3, width: 5.8 mm max.) for wiring. To
connect bare wires, use AWG22 (cross section: 0.326 mm2) to AWG14 (cross section:
2.081 mm2) to wire the power supply terminals and AWG28 (cross section: 0.081 mm2)
to AWG16 (cross section: 1.309 mm2) for other terminals. (Length of exposed wire: 6 to
8 mm)
(9) In order to prevent inductive noise, wire the lines connected to the product separately
from power lines carrying high voltages or currents. Do not wire in parallel with or in the
same cable as power lines. Other measures for reducing noise include running lines
along separate ducts and using shield lines.
(10) Ensure that the rated voltage is achieved no longer than 2 s after turning the power ON.
(11) Allow the product to operate without load for at least 15 minutes after the power is
turned ON.
(12) Do not install the product near devices generating strong high-frequency waves or
surges. When using a noise filter, check the voltage and current and install it as close to
the product as possible.
(13) Do not use thinner to clean the product. Use commercially available alcohol.
(14) Be sure to confirm the name and polarity for each terminal before wiring the terminal
block and connectors.
(15) Use the product within the noted supply voltage and rated load.
Precautions for Safe Use

VIII
(16) Do not connect anything to unused terminals.
(17) Output turns OFF when the mode is changed or settings are initialized. Take this into
consideration when setting up the control system.
(18) Install an external switch or circuit breaker that complies with applicable IEC60947-1
and IEC60947-3 requirements and label them clearly so that the operator can quickly
turn OFF the power.
(19) Use the specified cables for the communications lines and stay within the specified
DeviceNet communications distances. Refer to the User's Manual (Cat. No. N129) for
details on communications distance specifications and cables.
(20) Do not pull the DeviceNet communications cables with excessive force or bend them
past their natural bending radius.
(21) Do not connect or remove connectors while the DeviceNet power is being supplied.
Doing so will cause product failure or malfunction.
(22) Use cables with a heat resistance specification of 70ºC min.

IX
●Noise Countermeasures
Do not install the product near devices generating strong high-frequency waves or
surges, such as high-frequency welding and sewing machines.
(1) Mount a surge suppressor or noise filter to peripheral devices generating noise, in
particular, motors, transformers, solenoids, and magnet coils.
(2) In order to prevent inductive noise, wire the lines connected to the terminal block
separately from power lines carrying high voltages or currents. Do not wire in parallel
with or in the same cable as power lines. Other measures for reducing noise include
running lines along separate ducts and using shield lines.

Specifies the sensor types
connected to input A and input
B.
→P.5-27
Input compensation Auto-zero time
The compensation input
changes the display to the
preset compensation value.
→P. 5 - 6 1
Enables forced zeroing of the
frequency when no pulse has
been input for a specific period
of time.
→P.5-31
Teaching Key protection
During scaling, the input value
during measurement can be
set, as is, as the scaling input
value.
→P. 5 - 3 0
(Setting Scaling)

Outputs
Display
Comparative output pattern Hysteresis Output refresh stop
The comparative output
pattern can be selected as
standard output, zone output,
and level output.
→P.5-39
Prevents comparative output
chattering when the
measurement value fluctuates
slightly near the set value.
→P.5-42
Holds the output status when
comparative results outputs
other than PASS turn ON.
→P.5-49
PASS output change Output OFF delay Shot output
Comparative results other
than PASS and error signals
can be output from the PASS
output terminal.
→P.5-51
Connects the comparative output
OFF timing for a set interval.
Comparative output ON times can
be held when comparative results
change quickly.
→P.5-46
Produces a constant
comparative output ON time.
→P.5-44
Output logic Startup compensation timer Output test
Reverses the output logic of
comparative outputs for
comparative results.
→P.5-53
Constant-time measurements
can be stopped by an external
signal input.
→P.5-34
Output operation can be
confirmed without actual input
signals, by setting test
measurement values using
the keys.
→P.5-74
Linear output Standby sequence
Outputs currents or voltages
proportional to measurement
values as they change.
→P.5-57
Turns the comparative output
OFF until the measurement
value enters the PASS range.
→P.5-55
Display value selection Display color selection Display refresh period
The current display value can
be selected from the present
value, the maximum value,
and the minimum value.
→P.5-67
The PV display color can be
set to either green or red. The
present value color can be
switched according to the
status of comparative outputs.
→P.5-69
When inputs change quickly,
the display refresh period can
be delayed to reduce
flickering and make the
display easier to read.
→P.5-60
Position meter Scaling Comparative set value display
Displays the current
measurement value as a position
in relation to the scaling width on
a meter with 20 sections.
→P.5-71
Can convert the input signal to
any display value.
→P.5-28
The comparative set value
can be set to not display
during operation.
→P.5-68
