Troubleshooting a Simple Peristaltic Pump & Disassembly Guide for the Speed Controller Board

1. Troubleshooting Flow

1. Power-off Inspection

   • Verify all wiring connections are secure and correct.

2. Direct Power Test

   • Connect the motor leads directly to a power supply:

     • If the motor runs, the speed controller board is faulty.

     • If the motor does not run, the motor itself is defective.

2. Detailed Steps

2.1 Direct Motor Power Test

• Tools Needed: Multimeter, insulated gloves, screwdriver

• Steps:

  1. Turn off power and disconnect all wiring.

  2. Remove the terminal cover.

  3. Connect motor’s positive and negative leads to the power adapter.

  4. Power on and observe motor rotation.

• Diagnosis:

  • Smooth rotation → Faulty speed controller board

  • No rotation or stalling → Defective motor

2.2 Speed Controller Board Inspection

• Visual Inspection:

  • Look for burn marks, bulging capacitors, or cracks.

• Voltage Measurement:

  • Use a multimeter to check input/output voltages on the controller board.

• Component Replacement:

  • If capacitors or voltage regulators are damaged, replace them by soldering.

3. Disassembly Video Guide

• Video Demo:

  • Search “simple peristaltic pump speed controller board disassembly” on YouTube or the official site.

• Safety Tips:

  • Always power off before working.

  • Wear an anti-static wrist strap to protect electronic components.

Conclusion
With the direct power test and controller board inspection methods above, you can quickly identify why your simple peristaltic pump isn’t working and use the disassembly video to complete the repair.
