Features Section 1-1

1-1 Features

The K3NP Period Meter displays pulse input after performing the numeric conversion of the input.

The K3NP has the following functions.

Measurement The internal system clock counts the period between pulses or pulse-ON time

and displays it in a variety of modes.

In the following example, the internal system clock counts the time (T) between pulse INA and pulse INB. If there are 100,000 counts during the time (T), a passing speed (F1) of 1,200 (m/min) will be displayed according to the following calculation.

T = 1 system clock count (0.5 ms) x 100,000 = 0.05 s F1 = 1/T x 60 (m/min) according to the internal calculation method. Therefore, 1/0.05 s x 60 = 1,200 (m/min)

Example: Passing Speed F1

FUNCTION

Application example

Section 3-1

Measures the time taken by an object to travel the distance between A and B.

Basic Operation

Displays the speed of an object passing between A and B. The speed is obtained by multiplying the reciprocal of T by 60. T (time) is the time interval between INA turning ON and INB turning ON. If the distance between the INA sensor and INB sensor is 1 m, the displayed value is m/min. If the distance is other than 1 m, or if another unit of measurement is required, input an appropriate prescale value. Obtain display value D as follows:

D (m/min) = 1/T x 60 x a

T: Time interval between INA turning ON and INB turning ON (sec) a: Prescale value

Hold Measured Value

When the HOLD input turns ON while the K3NP is measuring, the measuring operation is canceled and the K3NP holds the last measured value (displayed value). While the HOLD input is ON, the K3NP holds comparative output and BCD output. Measurement will not begin while the K3NP is in HOLD status. This is illustrated in the following diagram.

When the comparative output terminals of the output board and the HOLD input terminals are connected, the value measured immediately after the occurrence of an error can be obtained.

The response time of the HOLD input is the time required for the K3NP to accept HOLD input after the HOLD input turns ON.

Recovery Time (T

) Recovery time is the period required for the K3NP to become ready for the

next measuring operation after a measuring operation is completed. For Transistor Output Models, comparative output remains ON during recovery time. For other models, comparative output requires more time to turn ON. When the comparative output terminals of the output board and the HOLD input terminals are connected, set a sufficient recovery period, considering the response time of the HOLD input. This is illustrated in the following diagram.

Response Time of HOLD Input

The response time of the HOLD input is the time required for the K3NP to accept HOLD input after the HOLD input turns ON. This is illustrated in the following diagram.

Recovery Time (TR) Recovery time is the period required for the K3NP to become ready for the

next measuring operation after a measuring operation is completed. For transistor output Models, comparative output remains ON during recovery time. For other models, comparative output requires more time to turn ON. When the comparative output terminals of the output board and the HOLD input terminals are connected, set a sufficient recovery period, considering the response time of the HOLD input. This is illustrated in the following diagram.

The following symbols are used for headings in this section.

This symbol precedes an explanation of the parameter’s meaning and function.

FUNCTION

This symbol precedes a description of the settings, setting range, and default value.

This symbol precedes a listing of the models in which this parameter can be used.

MODELS

4-1-2 Setting Procedures

· The K3NP 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 K3NP will vary depending on the Output Board installed. Refer to Appendix D Available Parameters.

· The K3NP is in RUN mode when the K3NP is turned on. Parameter settings in protect or setting mode are described below on the basis that the parameters are set for the first time.

For the operation in RUN mode, refer to Section 5 Operations in RUN Mode.

· The setting examples are provided on condition that the factory-set values of the K3NP have not been changed.

· The menu in each mode changes whenever the Mode Key is pressed.

· If the Mode Key is pressed for more than one second while a menu is dis-

played, a parameter will be displayed.

· The parameter changes whenever the Mode Key is pressed.

· If the Shift Key is pressed while a parameter is displayed, the parameter will be

ready to change.

· Press the Up Key to change parameters.

· The digit of a set value is selected with the Shift Key and changed with the Up

Key.

· The PROG indicator is lit while a menu or parameter is displayed.

· The PROG indicator flashes during a set value change.

Note If the operating mode is changed, all the other parameters will be set to default

values except for communication settings and set values in protect mode. Therefore, set the operating mode and sensor type first.

Teaching Function Section 6-1

6-1 Teaching Function

· The K3NP is provided with a teaching function that can set an actual measured value as a set value without any front panel key input.

This function is useful for setting parameters while checking the operating status of the K3NP.

· The teaching function can be used to set the setting, scaling values, and linear output range. The TEACH indicator will be lit if a parameter that can use the teaching function is displayed.

6-1-1 Set Value

· A setting value can be set with the actual input instead of key input in the setting mode.

· Follow the steps below to teach the setting value.

1, 2, 3... 1. Press the RESET/TEACH Key for more than one secondwhile the parame-

ter is displayed. The process value will be displayed and the teaching indicator will flash.

2. Press the RESET/TEACH Key again to retrieve the process value immediately before the key was pressed as a set value. The teaching indicator will be lit and the parameter will be displayed. Press the Escape Key to interrupt teaching.
