【 4.4 】 XMT Passive Current Signal
【 Mode Switch 】 :When the main interface 【 FN 】 is white.Press 【 IN/OUT 】 to switch
the display of actual value and engineering quantity of input/output
【 Output Range 】 : The limit range of passive current output can be set
【 4.5 】 Hz Pulse Signal
【 Mode 】 : The pulse signal has four modes: frequency, PWM duty cycle, speed frequency,
pulse quantitative/counting. When the main interface 【 FN 】 is white, long press 【 OUT 】
to switch mode
【 Range 】 : Select the range of frequency output: 0~99.999Hz, 0~999.99Hz,
0~9999Hz, 0~200kHz
【 Method 】 : Select level/open circuit according to the presence or absence of pull-up
【 Output Peak Value 】 : The level height of the output waveform, the highest is 24V
【 Frequency Mode Operation Instructions 】 :The frequency range can be switched
by pressing 【 OUT 】 when the main interface 【 FN 】 is white
【 Operating Instructions In PWM Mode 】 : PWM displays two parameters, the
frequency value (that is, the period value) and the duty cycle.The frequency value
will be displayed in the original engineering quantity position (no engineering
quantity display).Note that the maximum frequency does not exceed 9999Hz.The
frequency value/duty cycle parameters can be set when outputting.When the main
interface 【 FN 】 is white, press 【 OUT 】 to switch, there is a yellow cursor indication
【 Operating Instructions For Speed Mode 】 :
(1) The speed mode is used to calculate the speed of the motor or gear. One
revolution of the motor or gear produces 1 pulse, one minute is 3000 revolutions, so 1
second is 50 pulses
(2) 【 Time Unit 】 : Frequency=RPS(per second)*number of pulses per revolution,
RPM(per minute)=RPS*60, RPH(per hour)=RPS*3600.In the speed setting selection,
note that the maximum frequency does not exceed 9999Hz
(3) 【 Number Of Revolution Pulses 】 : The number of pulses per revolution of the
motor or gear, which can be selected in the speed setting
(4) 【 Tooth Missing 】 : It is mainly used to simulate the engine speed, select it in the
speed setting
【 Quantitative/Counting Mode Operation Instructions 】 : The main purpose of
pulse quantitative is to simulate the quantitative control sensor of flow.the frequency
value will be displayed in the original quantity position.The cycle is displayed at the
original engineering position, and the unit is milliseconds.When the main interface
【 FN 】 is white, press 【 OUT 】 to switch between cycle and quantitative values, which
are distinguished by cursors
The period value can be modified during quantitative output.In this mode, when
the cursor disappears after the output is turned on, the backlight of the up, down,
left, and right keys will turn blue.The function of the up, down, left, and right
buttons will also change, that is, the up is a single pulse sent.Down is program stop
and reset, left is no function, right is start/pause
