Scaling * Analog (Process) Inputs The K3MA-J converts input signals into desired physical values. INPUT2: DISPLAY2: INPUT1: DISPLAY1: Any input value Displayed value corresponding to INPUT2 Any input value Displayed value corresponding to INPUT1 When DISPLAY1 is set for INPUT1, and DISPLAY2 is set for INPUT2, a line will be displayed joining the two points. (Raise shift, reverse scaling, plus/minus display, etc., can be adjusted as desired.) Parameter Setting value inp.1 -19999 to 99999 Meaning Parameter Input value for dsp.1 dp Setting value %.%%%% Meaning Display four digits after decimal point dsp.1 -19999 to 99999 Input value for inp.1 %%.%%% Display three digits after decimal point inp.2 -19999 to 99999 Input value for dsp.2 %%%.%% Display two digits after decimal point dsp.2 -19999 to 99999 Input value for inp.2 %%%%.% Display one digit after decimal point %%%%% No decimal point Display value DISPLAY 2 ( ) DISPLAY 1 ( ) Display value DISPLAY 1 ( ) Reverse scaling also possible. The decimal point can be optionally displayed. When displaying the decimal point, consider the number of digits to follow the decimal point prior to setting the scaling display value. DISPLAY 2 ( ) INPUT 1 INPUT 2 Input value ( ) ( ) ( INPUT 1 ) INPUT 2 Input value ( ) Reverse scaling, where the display value decreases as the input value increases, is also possible. 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-J. 5 K3MA-J Convenient Functions Scaling Teach The parameters (inp.1, inp.2) for the K3MA-J's initial setting level can be set using actual input values with the teaching function. After displaying the parameters, the actual input settings can be made with the following operation. Teaching mode Use to shift to the next parameter without registering. "T" flashes. Monitor mode 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. Upper Limit (High Acting) OUT1/2 value Lower Limit (Low Acting) OUT1/2 upper-limit value Hysteresis Measurement value Measurement value ON Output OFF Hysteresis Measurement value Hysteresis OUT1/2 value Output Upper and Lower Limits (Outside Band Acting) Hysteresis OUT1/2 lower-limit value ON Output OFF ON OFF 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 OUT2 value Measurement value OUT1 value Threshold Output OUT2 upper-limit value OUT1 upper-limit value OUT1 lower-limit value OUT2 lower-limit value Measurement value Combination of Upper Limit and Upper/Lower Limits OUT2 Upper-limit value OUT1 value Measurement value OUT2 Lower-limit value ON OUT2 OFF OUT2 ON OFF ON OUT2 OFF ON OUT1 OFF OUT1 ON OFF ON OUT1 OFF 6 K3MA-J Parameter Initialization Changing the Display Color This function returns all of the parameters to their initial values. The color of the value displayed can be set to either red or green. For comparative output models (K3MA-J-A2), 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. Parameter Setting value init Meaning off --- on Initializes all parameters. Use this to reset the K3MA-J after returning it to its factory-set condition. Red 113.36 OUT1 value Green 100.05 Average Processing OUT2 value Average processing stabilizes displayed values to minimize flicker by averaging the fluctuating input signals. Average processing can be performed for the measurement values in either of four steps (OFF, 2 times, 4 times, or 8 times). 8.781 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). This is useful for ignoring rapid fluctuations, e.g., eliminating spike noise. Hysteresis (Comparative Output Models Only) The hysteresis of comparative outputs can be set to prevent chattering in the output when the measurement value fluctuates finely near the OUT value. Move-to-Protect-Level Time The time required to shift to the protect level can be set as desired. Forced-zero Function It is possible to shift from a value to the zero point with one touch of the Up Key on the front panel (for example, when adjusting reference values). Upper limit (high acting) Set value MAX/MIN Hysteresis LEVEL MODE SHIFT UP Measurement value Note: Used only for releasing the forced-zero with the Protect menu. MAX/MIN Display ON Output 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. OFF Zero-limit Function The zero-limit function changes any value below the set value to zero. This is useful when you want to change negative values to zero rather than display them, or when you want to make the display in the smallest part of the input range zero. Current value MAX/MIN MAX/MIN Parameter Setting value LEVEL MODE SHIFT UP Meaning =-lim off OFF: No zero-limit on ON: Zero-limit lim-p 0 to 99 0 to 99: Zero-limit value MAX value Max MAX/MIN MAX/MIN LEVEL MODE SHIFT UP Display MIN value Min MAX/MIN MAX/MIN LEVEL MODE SHIFT UP Zero-limit setting value Input 7 K3MA-J Nomenclature 2.

Insert the K3MA-J into the panel cut-out hole. 2. For a waterproof installation, insert the rubber gasket onto the body of the K3MA-J. Rubber Packing K32-P1 If the rubber packing is lost or damaged, it can be ordered using the following model number: K32-P1. (Depending on the operating environment, deterioration, contraction, or hardening of the rubber packing may occur and so, in order to ensure the level of waterproofing specified in NEMA4, periodic replacement is recommended.) Note: Rubber packing is provided with the Controller. 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 K3MA-J. Wiring Precautions * Use crimp terminals. * Tighten the terminal screws to a torque of approximately 0.5 Nm. * To avoid the influence of noise, route signal lines and power lines separately. Wiring * Use the following M3 crimp terminals. 5.8 mm max. Angle of View The K3MA is designed to provide the best visibility at the angles shown in the following diagram. 5.8 mm max.
