K-26 1/32 DIN Digital Panel Meter K3GN
Additional Information
■ Application as a Process Meter
The initial settings required when using the K3GN a process meter are explained below using the following example.
Setting Example
Inputs in the range 1 to 5 V are scaled to the range 0 to 100.0 kg and
displayed. If the measurement value goes over 70.0 kg, output 1
turns ON. If the measurement value goes below 50.0 kg, output 2
turns ON.
Initial Setting Procedure
1. Check the wiring and turn ON the power.
2. Set analog input as the input type.
If a measurement value is displayed (operation level), move to the
initial setting level by holding down the Level Key for 3 s min.
Set parameter in-t to analg.
3. Set the analog range to 1 to 5 V.
Set parameter range to 1-5.
4. Set the scaling values.
Set parameter inp.1 to 1.000.
Set parameter dsp.1 to 0.
Set parameter inp.2 to 5.000.
Set parameter dsp.2 to 1000.
5. Set the position of the decimal point.
Set parameter dp to %%%%.%.
6. Operating action for OUT1 and OUT2 set values.
Set parameter out1.t to hi.
Set parameter out2.t to lo.
7. Set OUT1 set value to 70.0 and OUT2 set value to 50.0.
If an initial setting level parameter is displayed, press the Level
Key for 1 s min. to return to the operation level.
Set parameter out1 to 70.0.
Set parameter out2 to 50.0.
8.
Start actual operation.
■ Application as a Tachometer
The initial settings required when using the K3GN as a tachometer are explained below using the following example.
Setting Example
The speed of a conveyor belt is displayed in m/min units. For every
revolution of the shaft, 4 pulses are output. The diameter of the axis
of rotation is 12 cm. If the Rotational speed goes over 10.500 m/min,
output 1 turns ON. If the speed goes below 9.500 m/min, output 2
turns ON.
Deciding the Scaling Value
Rotational speed (m/min) = π × Diameter (m) × Revolutions per
minute (rpm)
Revolutions per minute (rpm) = Input frequency (Hz) ÷ Number of
pulses per revolution × 60
Applying the appropriate values to these 2 equations gives: Speed
(m/min) = 5.654866... × Input frequency (Hz)
Multiply by 1,000 to display the first 3 digits to the right of the decimal
point.
Speed (m/min) = 5654.866... × Input frequency (Hz)

To limit inaccuracies due to scaling, select a round number
(e.g., 10) as the input value and select a display value of as
many digits as possible. In this example, scaling is performed
so that an input value of 10 gives a displayed value of 56549.
