k-14 1/32 din digital panel meter k3gn operation main functions input types and ranges scaling analog (process) inputs the k3gn converts input signal s into desired physical values. input2: any input value display2: displayed value corresponding to input2 input1: any input value display1: displayed value corresponding to input1 pulse frequency the k3gn converts pulse signal inputs into desired units such as revolutions or rotational speeds. the slope of the linear relation ship between the input value and dis- play value is calculated automatically when an input value and its corresponding display value are entered. input value: any arbitrary input value display value: desired display va lue corresponding to input value if scaling for pulse signals is no t performed, the input frequency will be displayed. the relationship between input, f, and display, d, is expressed in the form d = f a (multiplication factor). the value of a will vary accord- ing to the display unit. for example, if the display unit is rpm, y is given by the following: d = f 1/n 60 (i.e., a = 1/n 60) where n is the number of pulses per revolution and f is the input pulse frequency (hz). if the display unit is m/min, y is given by the following: d = f d 1/n 60 (i.e., a = d 1/n 60) where d = the wavelength (m) per revolution. example : when displaying the rotational speed (rpm) for a machine that generates 5 pulse signals per revolution, d is given by the follow- ing: d = f 1/5 60, so if f = 1, then d = 12. therefore, input 1 for inp and 12 for dsp . average processing the average processing function stabil izes displayed values by aver- aging the corresponding input signal s that fluctuate dynamically. hysteresis the hysteresis of comparative outputs can be set to prevent the chat- tering of relay or transistor outputs. input type (setting parameter) function input range (setting parameters) setting range analog input ( analg ) selects dc voltage/current signal input. 4 to 20 ma/0 to 20 ma ( 4-20 ) displayable from ? 19999 to 99999 with scaling function. the position of the decimal point can be set as desired. 1 to 5 v/0 to 5 v ( 1-5 ) 5 v ( 5 ) 10 v ( 10 ) pulse input ( pulse ) selects pulse input signal. 0.05 to 30 hz ( 30 ) 0 to 5 khz ( sk ) remote ( rmt ) displays digital data from plc or pc. --- input value input1 input2 input value displayed value displayed value display1 display2 display1 display2 input2 input1 inp dsp input value displayed value k3gn proximity sensor upper limit (high acting) set value output on off hysteresis measurement value
1/32 din digital panel meter k3gn k-15 panel indicators startup compensation time (pulse input only) the startup compensation time par ameter keeps the measurement operation from sending an unnecessa ry output corresponding to instantaneous, fluctuating input from the moment the k3gn is turned on until the end of the preset period. the compensation time can be set in a range from 0.0 to 99.9 sec- onds as the waiting time until t he devices subject to measurement become stable after the startup of the power supply. changing the display color the display can be programmed to change color when an output turns on. in an example, the k3gn can be programmed to display green for normal, and red for errors. the color can be set to change from either green to red or red to green when output turns on. k3gn can also be programmed to display only one unchanging color: red or green. teaching an actual measured value as a set value without any front panel key input can be set with the teaching f unction. teaching is useful for making settings while checking the operation status of k3gn. forced-zero function it is possible to shift the zero point to a desired value (such as might be required when adjusting reference values) with one touch of the up/zero key on the front panel. configurable output operating action output 1 and output 2 can be set to operate in one of the 3 following modes: upper limit (high acting): the output is turned on when the measured value is greater than its set value. lower limit (low acting): the output is turned on when the measured value is less than its set value. upper and lower limits (outside band acting): an upper limit (h set value) and lower li mit (l set value) can be set independently. the output is turned on when the measured value is greater t han upper-limit set value or less than the lower-limit set value. only transistor outputs have a pass output which is output when both out1 and out2 are off. the three types of output operations shown above can be combined as desired. the following are ex amples of possible combination s. out1 out2 sv zero hold cmw upper limit (high acting) out1/2 set value measurement value on off output hysteresis lower limit (low acting) out1/2 set value on off output hysteresis hysteresis measurement value hysteresis on off output measurement value upper and lower limits (outside band acting) upper-limit set value for out1/2 lower-limit set value for out1/2 upper limit 2-stage output threshold output on off out2 on off out1 out1 set value on off out2 on off out1 on off out2 on off out1 out2 set value out1 set value measurement value upper-limit out2 set value upper-limit out1 set value lower-limit out1 set value lower-limit out2 set value measurement value combination of upper limit and upper/lower limits upper-limit out2 set value lower-limit out2 set value measurement value
