Precautions for Safe Use

(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 mm

2.081 mm
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.

VII

(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.

Use the following procedure to change set values.

Procedure

A The parameter to be changed is displayed.

• At this stage, the set value is displayed but cannot be changed.

B Press the S [SHIFT] Key once to enable changing the setting.

• The place that can be changed starts to flash.

C Use the S [SHIFT] and U [UP] Keys to change the setting.

D Press the M [MODE] Key to switch to the next parameter.

• The changed set value is stored in the internal memory.

• If no key is pressed at step C for 5 s,* the set value is registered
and the display automatically returns to monitor status.

* If the display is on RUN level or adjustment level, the time before the

return to monitor status depends on the setting for the “automatic
display return time.” If the “automatic display return time” setting is
less than 5 s, for example, 3 s, then if there are no key operations in
change status for 3 s, the changed set value is registered and the
display automatically returns to the display when the power was
turned ON.

■ Confirming and Changing Comparative Set Values

Comparative set values are confirmed and changed in RUN level.
(The Unit keeps operating even while comparative set values are being
confirmed and changed.)

The comparative set values from HH to LL are displayed each time the
M [MODE] Key is pressed in the operation status immediately after
the power is turned ON. The SV display status is lit for
the displayed comparative set value.

5.5 Setting Prescale Values

Explanation of Functions Prescaling

Prescaling enables input values to be displayed using any unit by multiplying the input pulse frequency or
count by a specific coefficient.

Example:

This example shows the prescale value and the prescale set values for displaying the speed of a rotary
encoder that outputs 500 pulses per second. (The K3HB-R is used in function F1.)

D = fa

fa: Frequency A (Hz)

α: Prescale value A

D: Measurement value (rpm)

Prescale value (

Prescale value of Input A, X (mantissa): ps. ax = 2. 0000

Prescale value of Input B, Y (exponent): ps. ay = 10 -3

× 60 × α

α) = 1/500 = 0.002 = 2.0 × 10

5.9 Averaging Input

R

Average processing of input values smooths the displays and outputs for inputs with extreme fluctuations,
such as spike noise.

Explanation of Functions Average processing

There are two types of averaging: “simple” and “moving.” Select one type. The number of samples
(“averaging times”) can also be specified for the input values to be averaged.

Simple averaging is used when the display refresh period is to be lengthened. Moving averaging is used to
remove periodic noise superimposed on input signals.

The following graphs show the relationship between the data refresh periods for both simple and moving
averaging processes when the averaging times is set to 4.
