5 Operation ■ Main Functions Input Types and Ranges Note: The initial value for the input range is “4 to 20 mA (4-20).” Scaling • Analog (Process) Inputs The K3MA-J converts input signals into desired physical values. INPUT2: Any input value DISPLAY2: Displayed value corresponding to INPUT2 INPUT1: Any input value DISPLAY1: 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.) Input type (setting parameter) Function Input range (setting parameters) Setting range Input range (in-t) Selects DC voltage/current signal input 0 to 20 mA (0-20) Displayable from −19999 to 99999 with scaling function.

Input value Input value Display value Display value DISPLAY 2 DISPLAY 1 DISPLAY 1 DISPLAY 2 INPUT 1 INPUT 2 INPUT 1 INPUT 2 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. 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. Reverse scaling, where the display value decreases as the input value increases, is also possible.

Process Meter 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. 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. The three types of output operations shown above can be combined as desired. The following are examples of possible combinations. “T” lights to indicate that the parameter is valid for teaching. Monitor mode Teaching mode “T” flashes. Normal change “T” turns OFF. Use to register and shift to monitor mode. Use to shift to the next parameter without registering.

7 Parameter Initialization This function returns all of the parameters to their initial values. Use this to reset the K3MA-J after returning it to its factory-set condi- tion. Average Processing 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). 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 chatter- ing in the output when the measurement value fluctuates finely near the OUT value. 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. Changing the Display Color 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. 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 dis- play auto-return time). 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). Note: Used only for releasing the forced-zero with the Protect menu. MAX/MIN Display 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. Parameter Setting value Meaning init off --- on Initializes all parame- ters.

Precautions WARNING Do not touch any of the terminals while the power is being sup- plied. Doing so may result in electric shock. !Caution !Caution Do not disassemble the product or touch the internal components of the product while the power is being supplied. Doing so may re- sult in electric shock. !Caution !Caution Do not allow metal objects or wire cuttings to enter the product. Doing so may result in electric shock, fire, or malfunction. !Caution !Caution Perform correct settings for the product according to the control application. Failure to do so may cause unexpected operation, re- sulting in damage to the product or injury. !Caution !Caution Take safety measures, such as installing a separate monitoring system, to ensure safety even if the product fails. Product failure may prevent comparative outputs from being generated, resulting in serious accidents. Observe the following precautions to ensure safety. 1. Maintain the power supply voltage within the range specified in the specifications. 2. Maintain the load within the ratings specified in the specifications. 3. Check each terminal for correct number and polarity before con- necting it. Incorrect or reverse connections may damage or burn out internal components in the product. 4. Tighten the terminal screws securely. The recommended tighten- ing torque is 0.43 to 0.58 N⋅m. Loose screws may cause fire or malfunction. 5. Do not connect anything to unused terminals. 6. Provide a switch or circuit breaker so that operators can easily turn OFF the power supply when necessary. Also provide appro- priate indications of such devices. 7. Do not attempt to disassemble, repair, or modify the product. 8. Do not use the product where flammable or combustible gases are present. Application General Precautions 1. Do not use the product in the following locations: • Locations subject to direct radiant heat from heating equip- ment. • Locations subject to exposure to water, oil, or chemicals. • Locations subject to direct sunlight. • Locations subject to dust or corrosive gases (particularly sul- furic gas or ammonia gas). • Locations subject to severe changes in temperature. • Locations subject to icing or condensation. • Locations subject to shock or vibration. 2. Do not block heat dissipation around the product, i.e., provide suf- ficient space for heat dissipation. 3. Ensure that the rated voltage is reached within two seconds after the power is turned ON. 4. Conduct aging for 15 minutes min. after power is turned ON for correct measurement. 5. Do not touch the slit sections or terminals while the power is being supplied to prevent the product from being affected by static electricity. 6. Do not lay heavy objects on the product during use or storage. Doing so may deform or deteriorate the product. 7. Do not use paint thinner for cleaning. Use commercially available alcohol. Mounting • Mount the product to a panel that is 1 to 8 mm thick. • Install the product in a horizontal position. • Use crimp terminals that match screw sizes. Noise Prevention • Install the product as far as possible from devices that generate strong, high-frequency fields (such as high-frequency welders or sewing machines) or surges. • Install surge absorbers or noise filters on nearby devices that gen- erate noise (particularly, motors, transformers, solenoids, magnet coils, and other devices that have a high inductance component). • To prevent inductive noise, separate the terminal block wiring for the product from high-voltage or high-current power lines. Do not route the wiring for the product in parallel with or tie it in a bundle with power lines. Take the following countermeasures against inductive noise in input lines. Analog Signal Inputs • When using a noise filter for the power supply, check for the voltage and current and install it as close as possible to the Process Meter. • Do not install the product near radios, television sets, or wireless devices. Doing so may cause reception interference. Increasing Service Life • Do not use the product in locations where the temperature or humidity exceeds the ratings or where condensation may occur. When installing the product in a panel, be sure that the temperature around the product (not the temperature around the panel) does not exceed the ratings. The product service life depends on the ambient temperature. The higher the ambient temperature, the shorter the service life. To extend the product service life, lower the temperature inside the Process Meter. • Use and store the product within the temperature and humidity ranges given in the specifications. When gang-mounting Process Meters or arranging them vertically, heat generated by the Process Meters will cause the internal temperature to rise, reducing the ser- vice life. In such cases, consider forced cooling methods, such as using a fan to circulate air around the Process Meters. Do not, how- ever, allow only the terminals to be cooled. Doing so will increase measurement error. • The life of the output relays is greatly affected by the switching capacity and switching conditions. Use these relays within their rated load and electrical life. The contacts may fuse or burn if they are used past their electrical life. + − Line filter Power supply input Process Meter Signal input Process Meter Power supply input Surge absorber + − Signal input 2-conductor shielded cable Process Meter
