Please note:for the Installation Steps,please contact our after-seller if you need, thank you very much!

Steps Below:

1>. Install CTR-30A

Step 1: Install 3pcs 1K Metal Film Resistor on R2,R4,R6

Step 2: Install 3pcs 10K Metal Film Resistor on R1,R3,R5

Step 3: Install 1pcs 2.2K Metal Film Resistor on R7

Step 4: Install 18pcs LED.

Tips:

A. Note the direction of the LED

B. Control distance between PCB edge and LED head(Two ways).

1). User can bend the LED pin at first after determining the distance and then insert LED to PCB through hole;

2). Insert LED to PCB through hole at first.Then determine the distance.Bend the LED pin at last.

Step 5: Install 3pcs 47uF 16V Electrolytic Capacitor

Step 6: Install 3pcs TO-92 S9014 Transistor

Tips: It is better to bend S9014's pin so that 2pcs PCB CTR-30A and CTR-30B can better splicing.

OK, CTR-30A has been installed completed.

2>. Install CTR-30B

Step 7: Install 3pcs 1K Metal Film Resistor on R2,R4,R6

Step 8: Install 3pcs 10K Metal Film Resistor on R1,R3,R5

Step 9: Install 18pcs LED.

Step 10: Install 3pcs 47uF 16V Electrolytic Capacitor

Step 11: Install 3pcs TO-92 S9014 Transistor

Step 12: Connect 5V to CTR-30A and CTR-30B.Preliminary welding success if LEDs are blinking automatically

3>. Stitching CTR-30A and CTR-30B

Step 13: Align the two positioning heads on CTR-30A and CTR-30B and then fixed with tin.

4>. Install CTR-30C

Step 14: Install Power Socket.Use a superfluous pin to fixed the power supply socket.This pin can come from resistor.

Step 15: Install 1pcs Self-Locking Switch. Note the direction of switch. The concave side is close to the PCB edge.

Step 16: Install battery box and fixed by screw/nut.

Tips:

First peel the insulation of the wire, and then welding fixed, and then cut off the excess wire

Step 17: Fixed CTR-30A and CTR-30B on CTR-30C.Align the two positioning heads and then fixed with tin.

Step 18:Install the top LED.Note the positive and negative of LED.At this point, the installation is complete!!

Enjoy the Completed Project Below:
