DISPLAY If p-fre is set to 30, the initial setting for the decimal display will be 000.00. INPUT Input value Teaching with actual values is possible. Instead of setting by inputting with the Up Key and Shift Key, current values can be input as scaling input values for teaching. This is useful for making settings while checking the operation status of the K3MA-F. 5 K3MA-F Convenient Functions Scaling Teach The parameter (inp) for the K3MA-F’s initial setting level can be set using actual input values with the teaching function. After displaying the parameter, the actual input settings can be made with the following operation. Teaching mode Monitor mode Use to shift to the next parameter without registering. “T” flashes. Use to register and shift to monitor mode. Normal change “T” lights to indicate that the parameter is valid for teaching. “T” turns OFF. Next parameter OUT Types (Comparative Output Models Only) OUT 1 and OUT 2 can be set to operate in one of the three following modes in accordance with the compared values: • Upper limit (High Acting): The output is turned ON when the measurement value is greater than its set value. • Lower limit (Low Acting): The output is turned ON when the measurement value is less than its set value. • Upper and lower limits (Outside Band Acting): An upper limit (H set value) and lower limit (L set value) can be set independently. The output is turned ON when the measurement value is greater than upper-limit set value or less than the lower-limit set value. Parameter Set value out1.t or out2.t hi Upper limit: Upper-limit alarm operation lo Lower limit: Lower-limit alarm operation hi-lo Upper Limit (High Acting) OUT1 value Lower Limit (Low Acting) Measurement value OUT1 value ON Output OFF Upper and lower limits: Upperand lower limit alarm operation Upper and Lower Limits (Outside Band Acting) OUT1 upper-limit value Measurement value Hysteresis Measurement value Meaning Hysteresis ON Output OFF Hysteresis OUT1 lower-limit value ON Output OFF Hysteresis The three types of output operations shown above can be combined as desired. The following are examples of possible combinations. Upper Limit 2-stage Output Threshold Output OUT2 upper-limit value OUT2 value OUT1 upper-limit value Measurement value Combination of Upper Limit and Upper/Lower Limits Measurement value OUT1 lower-limit value OUT1 value OUT2 lower-limit value OUT2 upper-limit value OUT1 value Measurement value OUT2 lower-limit value OUT2 ON OFF OUT2 ON OFF OUT2 ON OFF OUT1 ON OFF OUT1 ON OFF OUT1 ON OFF Parameter Initialization Use this to reset the K3MA-F after returning it to its factory-set condition. This function returns all of the parameters to their initial values. Parameter init Setting value Meaning off --- on Initializes all parameters. 6 K3MA-F Average Processing Changing the Display Color Average processing stabilizes the display by minimizing any pulsating or flicker caused by fluctuations in the pulse width of sensor input or by eccentricity in rotating shafts. The color of the value displayed can be set to either red or green. For comparative output models, the display color can be set to change from green to red, or from red to green, according to the status of the comparison criterion. Red 113.36 OUT1 value Green 100.05 Hysteresis (Comparative Output Models Only) OUT2 value 8.781 The hysteresis of comparative outputs can be set to prevent chattering in the output when the measurement value fluctuates finely near the OUT value. Upper limit (high acting) Set value Red Display Auto-return Time This function automatically returns the display to the operation level’s current value if no keys are pressed for a preset time (called the display auto-return time). Hysteresis Move-to-Protect-Level Time Measurement value The time required to shift to the protect level can be set as desired. Output MAX/MIN Display ON OFF Auto-zero Time This function sets the time for the display to return to zero when input pulses stop. Set the time longer than the expected input pulse cycle (the interval between one input pulse and the next). Proper measurement is not possible if the time is set shorter than the input pulse cycle. Setting range: 0.0 to 19.9 s The maximum and minimum measurement (display) values from the time the power is turned ON until the current time can be stored and displayed. This is useful, for example, when measuring the maximum value. Current value MAX/MIN MAX/MIN Startup Compensation Time LEVEL MODE SHIFT UP MAX value Max The startup compensation time is the time to wait for the measurement operation to be entered after the power supply of the K3MA-F is turned ON. Use this parameter to cancel measurement and comparative output operation until the a rotating body reaches its normal speed when the power supply to the K3MA-F and rotating body are turned ON at the same time.

Example: Display conveyor belt feed speed E2E-X5E1 Proximity Sensor 0.1 m 1 2 Max Min SV MAX/MIN LEVEL MODE SHIFT UP K3MA-F-A2 100-240VAC Here, the conveyor belt feed speed is to be displayed in units of 0.1 m/min. • Proximity Sensor: E2E-X5E1, NPN output 1 pulse/rotation, roller diameter 0.1 m Display value dsp 18850 1. Select the maximum input frequency for the K3MA-F. Set the pulse frequency selection to either 30 Hz or 5 kHz. In the example, this is set to 30 Hz because the conveyor belt is turning at a slow speed. Parameter: p-fre (pulse frequency), Setting value: 30 2. Set the scaling. The display value (D) is shown with the following formula. D = f × α, f: frequency and α: prescaling value The value of α will be internally calculated and registered if the input value (f) and the display value (D) are set. The number of rotations or speed is shown with the following formula. Rotations (rpm) = Frequency input/No. of pulses per rotation × 60 Cycle speed D (m/min) = Rotations × roll circumference = 1/N × f × 60 × d × π N: No. of pulses per rotation f: Frequency (Hz) d: Roller diameter (m) When the input conditions are applied to this equation, we obtain the following: Display value = 1/1 × f × 60 × 0.1 × π For an input of 1 Hz, the display value is 18.8495 (m/min). The scaling settings for the K3MA-F must be integers. Also, to decrease error, the scaling value is multiplied by 1,000, to obtain an input of 1000 Hz and a display value of 18850. However, because the display value in this case is displayed to the first decimal place, the scaling is set as shown in the following example so that 1885.0 is displayed for an input of 100 Hz. Parameter Setting value inp (scaling input value) 100 dsp (scaling display value) 18850 dp (decimal point position) %%%%.% Input value inp 100 When displaying a flowrate (e.g., in l/min or l/h), make the scaling settings after confirming the I/O characteristics of the flowrate sensor. There are flowrate sensors that output analog signals. If this kind of flowrate sensor is used, consider using the K3MA-J. Note: The decimal point position here refers to the position in the number after scaling. When setting the scaling display value, it is necessary to consider the number of digits to be displayed past the decimal point. ■ Troubleshooting When an error occurs, error details will be displayed on the main indicator. Confirm the error from the main indicator and take the appropriate countermeasures. Level display Main indicator Error contents Countermeasures Not lit e111 RAM memory error Repair is necessary.
