■List of Models

Note: Refer to page 5 for information on models with normally energized relays.

Specifications

■Ratings

Note: 1. A control power supply capacity greater than the rated capacity is required when the Digital Panel Meter is turned ON. Do not forget to

take this into consideration when using several Digital Panel Meters. When power is supplied, all indicators will light and outputs will be

OFF. When using startup compensation time operation, the display will read “00000” and all outputs will be OFF.

2. Enabled only when using DC voltage/current input. (Min.time for control signal input: 80 ms)

•The drive operation for the output relay is reversed in these models.

•Relay contacts can be made open (i.e., OFF) when comparative set

that take failsafe measures into consideration.

Linear Output

Note: The commons for linear output and transistor output on models

with L1 and L2 are connected internally.

Depending on how the common is wired for externally

connected devices, unwanted current paths for the linear

output signal in the circuit may prevent the output signal from

being output.

When connecting an external device, externally connect a relay

to the transistor output or provide another means of insulation.

Note: The default value is 4-20: 4 to 20 mA input range.

Note: The default value is 199.9: ±199.9 mV input range.

Pulse Frequency

Note: The default value is 5k: 5 kHz input range.

Setting Scaling

Analog Input Signal

(Refer to page 10 if a pulse input is selected.)

•The scaling will be displayed on a line connecting two points by setting Display 1 for Input 1 and

Display 2 for Input 2.

The position of the decimal point can be set as desired. If the decimal point is to be displayed, it is

necessary to consider the number of digits to be displayed past the decimal point when setting the

scaling display value.

Note: When pulse input is used, the base point is the 0 point, so the settings are only the input

value and the display value.

Instead of setting by inputting with the Shift Key and Up Key, current measurement values van be

input as scaling input values for teaching. This is useful for making settings while checking the

operation status of the K3GN.

K3GN

•If the K3GN is used with a pulse signal input, the display value will be the input frequency if scaling is not performed.

Display the rate of rotation or the speed of a device or machine to which the K3GN is mounted by converting using scaling.

The relation between input f (Hz) and display D is expressed in the form D = f x a (factor). The value depends on the display unit. The formula

will be comprised as follows:

Display using rpm: D = f x 1/N x 60, N = Number of pulses per rotation, f = Input pulse frequency (Hz) (i.e., number of pulses in one second)

Display using m/min: D = f x π d x 1/N x 60, π d = Circumference length (m) per rotation

Output 1 Type

Note: The default value is hi: Upper limit.

Prescaling Example

To display the rotational speed of a device that outputs five pulses

per rotation:

D = f × 1/5 × 60, and,

If f=1,

D = 12, so

The setting will be completed by inputting inp:1 and dsp:12.

Output 2 Type

Note: The default setting is lo: Lower limit.

The output operations can be selected separately for OUT1 and OUT2.

K3GN

Operation

■Main Functions

Scaling

The K3GN includes a scaling function that can convert the input

signal to a desired value and display that value.

The displayed values can be freely adjusted to shift values, to create

reversed displays, or to create positive/negative displays.

Teaching

Teaching is used when using scaling or setting comparative set

values to set the present measurement values as the set values

instead of inputting with the Shift and Up/Zero Keys. Teaching is

useful for making settings while checking the operation status of the

K3GN.

Average Processing

Average processing can be performed for measurement values

using four levels (OFF, 2 times, 4 times, or 8 times). Average

processing stabilizes displayed values by averaging the

corresponding input signals that fluctuate dynamically. Select the

appropriate number of averaging times depending on the application.

Forced-zero Function

It is possible to shift from a

value to the zero point with

one touch of the Up/Zero

Key on the front panel (for

example, when adjusting

reference values).

Note: This function can be

used only when

forced-zero operation

protection is released.

Changing the Display Color

The color of the value displayed can be set to either red or green.

Make the setting according to the purpose and application of the

equipment in which the K3GN is installed. The display color can also

be set to change from green to red, or from red to green, according

to the status of the comparison criteria.

Output Type Selection

Output operation for comparative set values can be freely selected.

Upper limit: Output ON if the measurement value ≥ comparative set

value.

Lower limit: Output ON if the measurement value ≤ comparative set

value.

Upper/lower limit: Output ON if the measurement value ≥

comparative upper-limit set value or if the measurement value is ≤

the comparative lower-limit value.

Key Protection

Key protection is used to restrict changes to displays and settings

using the front panel keys and to restrict menu display and

movement of operation levels. This function is effective for

preventing misuse during operation.

Startup Compensation Time (Rotary

Pulse Input Only)

The startup compensation time parameter keeps the measurement

operation from sending an unnecessary output corresponding to

instantaneous, fluctuating input from the moment the K3GN is turned

ON until the end of the preset period.

Hysteresis

The hysteresis of comparative outputs can be set to prevent the

chattering of relay or transistor outputs.

Dimensions

Note: All units are in millimeters unless otherwise indicated.

Installation

1. Insert the K3GN into the panel cut-out hole.

2. For a waterproof installation, insert the rubber gasket onto the

body of the K3GN.

3. Fit the adaptor into the grooves on the left and right sides of the

rear case, then push it until it contacts the panel to secure the

K3GN.

Angle of View

The K3GN is designed to provide the best visibility at the angles

shown in the following diagram.

■Rubber Packing

The Rubber Packing ensures a waterproof level conforming to

NEMA4X. Depending on the operating environment, deterioration,

contraction, or hardening of the Rubber Packing may occur, making

replacement necessary. Contact your OMRON representative if

replacement is required.

■Wiring Precautions

•Wire the power supply with the correct polarity. Wiring with

incorrect polarity may result in damage or burning.

•Wire the terminals using crimp terminals.

•Tighten terminal screws to a torque of approx. 0.5 N·m.

•Wire signal lines and power lines separately to reduce the influence

of noise.

■Wiring

Power Supply

•Input 24 VDC to terminals 1 and 2.

•Use M3 crimp terminals of the type shown below.
