Do not attempt to disassemble, repair, or modify the product. Doing so may occasionally result in minor or moderate injury due to electric shock.

Precautions for Safe Use

 Precautions for the environment.

(1) Do not use the product in the following locations.

• Locations subject to direct radiant heat from heating equipment

• Locations here 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. Parts life is dependent on temperatures. A part life shortens when the temperature rises, and it lengthens when the temperature falls. Parts life can be lengthened by lowering the temperature inside the product.

(3) 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.

(4) 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. If several products are mounted side-by-side or arranged in a vertical line, the heat dissipation will cause the internal temperature of the product to rise, shortening the service life. If necessary, cool the products using a fan or other cooling method.

(5) Take care when cleaning the product, because the exterior of the product contains

organic solvent (thinner, benzine, etc.), strong alkaline material and strong acid material.

(6) Avoid storing in high humidity or in a corrosive gas environment (including during

transportation)

 Precautions for Safe Use.

(1) Use and store within the proper temperature and humidity described in the specifications.

(2) Provide sufficient space around the product for heat dissipation.

(3) When using the product stored unused over a year after purchasing, the product features

may not be utilized sufficiently.

(4) Avoid storing outdoors and in a place that receives direct sunlight (including during

transportation).

(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) Be sure to confirm the name and polarity for each terminal before wiring the terminal

block and connectors. Faulty wiring causes destruction or burnout of internal parts.

(7) Use the product within the noted supply voltage and rated load.

(8) Do not connect anything to unused terminals.

(9) Output turns OFF when the mode is changed or settings are initialized. Take this into

consideration when setting up the control system.

(10) Install an external switch or circuit breaker and label them clearly so that the operator can

quickly turn OFF the power.

(11) Ensure that the rated voltage is achieved no longer than 2 s after turning the power ON.

When applying a voltage gradually, power supply may not be reset or output functions indeterminately.

(12) Mount to a panel between 1 and 5 mm thick.

(13) Use the specified size of crimp terminals (M3, width : 5.8 mm max.) for wiring. To

connect bare wires, use AWG 28 to AWG 16 to wire the power supply terminals and AWG 22 to AWG 14 for other terminals. (Length of exposed wire : 6 to 8 mm)

(14) Allow the product to operate without load for at least 15 minutes after the power is

turned ON.

Precautions for Correct Use

(1) Install the product horizontally. Display error has the risk of becoming larger than the standard because heat

cannot be radiated.

(2) When using a noise filter on the power supply, check that the filter is suitable for the supply voltage and

current ratings, and then attach the noise filter as close as possible to the K3GN.

4.1 Using the Product as a process meter

The following example shows the flow of initial setting for the product that is used as a process meter.

Setting example:

Input signals ranging from 1 to 5V is scaled to readouts ranging from 0 to 100 kg. Comparative output 1 is produced when the process value (readout) reaches

70.0 kg. Comparative output 2 is produced when the process value (readout) decreases to 50.0 kg.

INITIAL

SETTING

Note

The input type, analog range, scaling factor, and decimal point position should be set in this order. Otherwise, auto-initialization of parameters may result in a failure in parameter setting. If you specify the scaling factor and then the input type, for example, the analog range and the scaling factor are initialized automatically.

Flow of Initial Setting

A. Check wiring for correct connection and power the product on.

The product is factory set to have an analog input range of 4 to 20 mA. If an input that falls outside this default range is received, the main indicator of the product will read “s.err” and blink, indicating an “input range over” error occurs.

B. Set “input type” to “analog”.

1. Make sure the main indicator displays a process value (the product is

at the operation level). Then press the L key and hold it down for at least one second. The product will move to the initial setting level.

2. Set parameter “in-t” to “analg”.

C. Set “analog range” to “1 ~ 5V”.

1. Set parameter “range” to “1-5”.

D. Specify the scaling factor.

1. Set parameter “inp.1” to “1.000”.

2. Set parameter “dsp.1” to “0”.

3. Set parameter “inp.2” to “5.000”.

4. Set parameter “dsp.2” to “1000”.

E. Specify the decimal point position.

1. Set parameter “dp” to “,,,,.,”.

SETTING

TIPS

The number of measurements for averaging and the hysteresis can be changed if required. These parameters are to be set at the advanced-function setting level.

4.1 Using the Product as a process meter

F. Set “OUT1 value type” to “upper limit” and “OUT2 value type” to “lower

limit”.

1. Set parameter “out1.t” to “hi”.

2. Set parameter “out2.t” to “lo”.

G. Set the OUT1 value to “70.0” and the OUT2 value to “50.0”.

4.2 Using the Product as a Tachometer

The following example shows the flow of initial setting for the product that is used as a tachometer.

Setting example:

The speed of a conveyor belt is indicated in terms of m/min. Four pulses are generated per rotation of the rotor. The diameter of the rotor is 12 cm. Comparative output 1 is produced when the speed reaches 10500 m/min. Comparative output 2 is produced when the speed decreases to 9500 m/min.

How to Determine the Scaling Factor

Determine the scaling factor as follows.

Note

The input type, pulse frequency, scaling factor, and decimal point position should be set in this order. Otherwise, auto-initialization of parameters may result in a failure in parameter setting. If you specify the scaling factor and then the input type, for example, the pulse frequency and the scaling factor are initialized automatically.

Rotor rotational speed (rpm) = Input frequency (Hz)/Number of pulses per rotation × 60

Belt Speed (m/min) = π × Rotor diameter (m) × Rotor rotational speed (rpm)

Hence the belt speed is given as

Belt speed (m/min) = 3.14159… × 0.12 × 60/4 × Input frequency (Hz) = 5.654866… × Input frequency (Hz)

Multiply the result by 1000 to enable a readout to be displayed to three decimal places.

Belt speed (m/min) = 5654.866… × Input frequency (Hz)

To minimize the scaling operation error, select such an input frequency that allows readouts to contain the largest possible number of digits. In this example, the

Readout

input frequency is set to 10 Hz so that the readout is

56549.

5.4 Set Values

Parameter settings are called “set values”. Set values include those consisting of “numerics” and “alphabets”.

A state in which a set value is being displayed on the main indicator is called “the monitor state”. A state in which a set value can be changed is called “the change state”.

Perform the following steps to display or change a set value.

TIPS

During setting of operation or adjustment level parameters, the return action of the product varies depending on the “display auto-return time” setting. The display auto-return time defaults to ten seconds. If the “display auto-return time” is set to less than five seconds, e.g., three seconds, no key operation for three seconds in the change state will return the product to the current value display mode, not to the monitor state.

Procedure

A. Press the S key when a parameter is displayed on the main indicator.

The product enters the monitor state and the set value of the parameter will be displayed on the main indicator.

• When the product is in the monitor state, “SV” in the operation indicator section is illuminated, indicating the readout on the main indicator is a set value.

B. If you do not want to change the set value, press the M key in the monitor

state to go to the next parameter.

C. Press the S key in the monitor state to cause the product to enter the

change state.

Note

The forced-zero operation is not available if the input type is set to "pulse".

The forced-zero operation allows you to shift the current value to zero forcedly. For details, refer to CHAPTER 6 FUNCTION DESCRIPTION.

Procedure

(for forced-zero operation)

When the process value increases or decreases to this value, comparative output 1 is provided.

When the process value falls outside the range specified by these values, comparative output 1 is provided.

When the process value increases or decreases to this value, comparative output 2 is provided.

When the process value falls outside the range specified by these values, comparative output 2 is provided.

TIPS

ZERO

If the panel is used for executing the forced-zero operation, the forced-zero process is stored in EEPROM. But if the forced-zero operation is executed via the event input terminal or communications, the process is not stored.

If the current value is not normal (e.g., the input signal is invalid, the process value is outside the displayable range, or no measurements are made), the forced-zero function is inoperative.

5.12 Specifying the Scaling Factor for Input Pulse Frequency

How to

Determine

Appropriate

Scaling Factors

To minimize the scaling operation error, select such a scaling factor that permits the largest possible number of digits to be contained in scaling display values (DSP).

The relationship between the scaling input and display values for input pulse frequency is represented by the following equation.

Scaling display value = α (multiplication factor) × input frequency (Hz)

Where α = DSP/INP

α is often an indivisible number such as 5.654866… particularly when the input value is converted to a circumferential velocity. This is because such a conversion involves π.

There are innumerable combinations of scaling input values (INP) and scaling display values (DSP) that result in α = 5.654866… as follows.

INP (Hz) DSP

1 2 5 10

···

5.654866···

11.30973···

28.27433···

56.54866···

On the other hand, DSPs that are programmable are limited to 5-digit integers. This means that DSPs must be rounded off to the nearest integers as follows.

INP (Hz) Programmable DSP

1 2 5 10

···

00006 00011 00028 00057

Hence, if the input frequency is 1000 Hz, the error between the scaling result and the ideal value increases with the decreasing number of digits contained in the DSP.

INP (Hz) Programmable DSP

1 2 5 10

···

00006 00011 00028 00057

Scaling result (readout)

Ideal value | Error |

5655 5655 5655 5655

345 155 55 45

Select a combination of the DSP and INP so that the scaling output contains the largest possible number of digits. Doing so minimizes the scaling operation error.

auto.z

(AUTO.Z)

When the input type has been set to "pulse", this parameter allows you to specify the auto-zero time.

Before specifying the auto-zero time, you must set the input type to “pulse”.

Parameter Set value Description

0.0

auto.z

The auto-zero time is the length of time required for the product to return the readout to zero after pulse input interruption.

Set this parameter to a larger value than the expected time interval of input pulses (interval between input pulses). Failure to do so will result in incorrect measurements.

If the auto-zero time is too long, on the other hand, a long delay in lower-limit action in response to a stop of rotation may result.

In the following application where a pulse is produced per rotation, for example, the input pulse frequency is 0.2 to 100 Hz, which means the time interval of input pulses is 0.01 to 5 seconds.

The auto-zero time should therefore be set to five seconds or longer.
