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.

Depending on how the common is wired for externally
connected devices, unwanted current paths for the linear

being output.
When connecting an external device, externally connect a relay
to the transistor output or provide another means of insulation.

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.
For details on the operating procedures, refer to the K3GN Digital Panel Meter Manual (Cat. No. N102).
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.

Note:The default setting is lo : Lower limit.
The output operations can be selected separately for OUT1 and OUT2. Output type Parameter
