1,RD(red wire) connects to DC9-24V positive pole;
2,BK(black wire) connects to DC9 ~ 24V negative pole, and it is also 4-20mA-/1-5V-/2-10V's negative pole;
3,GR(green wire) connects to analogy signal positive pole(e.g. 4-20mA, 1-5V, 2-10V) ;
4,YW(yellow wire) connects to ERROR output negative pole. Wet contact NPN triode collector output. When there is an error causing the motor to work with excessive current, such as when debris blocks the valve and the ball cannot rotate, the contact is closed; when working normally, the contact open, it only can pull down the external signal. The load is 500mA
5,WT(white wire) connects to position feedback negative pole.
Wet contact NPN triode collector output, OC output PWM signal, 100Hz, 5%-95%, indicating 0-90 degrees. The load is 500mA.
*PWM: Connecting a pull-up resistor to WT and RD, usually use a 1k or 5.1k resistor, recommend to use 1k for power supply below 15V, and 5.1k for over 15V. Oscilloscope clamp connects to power's negative pole, and oscilloscope probe connects to PWM white wire.
*5%-95% represents duty cycle, which is the ratio of VCC time to the cycle time.
*PMW signal is a signal to give position feedback, the error signal needs to be connected with a 10k resistor to power's positive pole. When blocking occurs, the error signal to the ground voltage will be lower, at this time, it is able to test signal with oscilloscope.
