Operation
Setting Procedures
The K3NC has four modes: RUN mode for normal operations, Setting mode for initial parameter input, Protect mode for lock-out configuration,
and Maintenance mode for initializing set values. The parameters that are accessible on any individual K3NC will vary depending on the Output
Board installed. Refer to the K3NC Operation Manual for details.
RUN Mode: Remains in this mode under normal operation.
The process value can be monitored.
Using the front panel keys, the comparative set value can be changed and counting value reset can be performed.
Setting Mode: Used for making initial settings.
Includes settings for four menus (Set value ( sUset ), prescaling ( pscl ), setup ( setup ), option ( opt )) and the output test.
Protect Mode: Used for locking the front key operation or parameter changes.
Maintenance Mode: Used for initializing set values.

Prescaling
The prescale function makes it possible to convert the counting val -

of the K3NC into an appropriate value.
For example, the system shown in the illustration outputs 250
pulses
when the object is advanced 0.5 m. T o enable the K3NC to
display jjjj.j (mm), obtain the advanced length of the object
per pulse from the following formula.
500 mm (0.5 m)/250 = 2

exponent Y as follows:
Prescale value = 2.0000 x 10

Approximately 30 ms after the REQ signal rises, a sample is taken and the DA T A V ALID signal is output. Read the data when the DA T A V ALID
signal is ON.
The DA TA V ALID signal will turn OFF in 40 ms, and then in 16 ms, the data will go OFF .
Models with a BCD output have an open collector output configuration so that wired-OR connection is possible.
*The period between the DA TA V ALID signal and the
REQ signal should be no less than 20 ms max.

Output Operation Timing in RUN Mode (Relay and Transistor Outputs)
The K3NC can output the results of Up/Down counting as comparative outputs.
The output mode can be set to the ALL-H mode or the ALL-L mode.
ALL-H
If the ALL-H output mode is selected, outputs 1 to 5 will be
ON when the measured value exceeds set values 1 to 5.
ALL-L
If the ALL-L output mode is selected, outputs 1 to 5 will be
ON when the measured value is less than set values 1 to 5.

While the reset signal is ON, the counting value will return to zero.
When the compensation signal is ON, the K3NC will be in counting operation starting with the preset compensation value. Depending on the
setting conditions, the compensation value will be effective only for the incrementing operation.
Output Delay (Reference Value)
The following table shows the time required for a K3NC in a system to go into reverse output operation after the counting value reaches the
value preset with the K3NC, and is due to the output processing time of the K3NC, signal transmission time of the system, and the relay con -
nected
to the K3NC.
Control I/O Output or response delay time
Relay contact output 3.0 to 10.0 ms
NPN/PNP transistor output 0.1 to 0.6 ms
Reset input 12.0 to 16.0 ms
Compensation input 12.0 to 16.0 ms
Bank switch 60.0 to 100.0 ms
Note: Output delay time varies with the operating environment. If the output delay time will possibly have a serious influence on your system,
check the actual output delay time before applying the K3NC to the system.

Precautions
•Be careful not to touch any terminals, otherwise you may receive
an electric shock.
•Please do not disassemble the product nor touch the internal
components of the product, otherwise you may receive an
electric shock.
•Be sure that the power supply voltage is within the rated range.
•Do not use the Intelligent Signal Processor in locations with
flammable
gas or combustible substances.
•Be sure to wire the terminals correctly by checking the terminal
names.
•Be sure that the terminal screws are tightened securely when
wiring.
Mounting
Recommended panel thickness is 1 to 3.2 mm.
Panel
Attach
the mounting bracket on the left and right sides of the Intelli -
gent
Signal Processor as shown in the illustration above and gradu -
ally
tighten each screw evenly in turn by considering the balance of
the tightening force until the ratchets start slipping without being fur -
ther
tightened.
Mount the Processor as horizontally as possible.
Never use the Processor in locations where corrosive gas (particu -
larly
sulfur or ammonia gas) is generated.
As much as possible avoid use of the Processor in a location subject
to severe shock or vibration, excessive dust, or excessive moisture.
Select an indoor mounting location where the Intelligent Signal Pro -
cessor is at the rated temperature and humidity and free from direct
sunlight.
Separate
the Processor from machines generating high-frequency
noise, such as high-frequency welding machines and high-frequen -
cy
sewing machines.
Operation
A Processor model with a Relay Contact or T ransistor Output Board
may not output any alarm signal normally if the model has an error . It
is recommended that an independent alarm device be connected to
the model.
The parameters are factory-set so that the Processor will operate
normally.
The settings of the parameters may be changed accord -
ing
to the application.
Unit Label (Attached)
No product is shipped with the unit label attached. Select a unit label
from the sheet provided and attach it to the Processor .
