Preface

Thank you very much for using our powered roller conveyor products. To ensure normal and reliable operation, please read this manual before use.

Non-operators should carefully read the operating conditions noted in the technical documents before the equipment runs. Improper installation or use can cause abnormalities. If abnormalities occur, please follow the troubleshooting methods in this manual; if unresolved, shut down the equipment and contact our customer service promptly.

If an accident occurs during operation, running, maintenance, or repair because the operator fails to ensure electrical and surrounding environment safety, our company does not assume responsibility, even if these terms are not explicitly emphasized in this manual.

1. Introduction and Usage Instructions

A powered roller conveyor is a conveying device used in automated final assembly lines and warehousing logistics, primarily composed of a frame, rollers, motor, and drive system.

According to product process requirements, the equipment drives the rollers through a motor to transport items. Its main advantages include:

• Small footprint

• High extensibility

• Ability to flexibly change the direction of conveyed goods

• Can turn to avoid obstacles

• Can withstand significant impact loads

• Simple structure

• Easy maintenance

• High reliability

---

2. Structure

The powered roller conveyor frame is made of standard carbon steel (square tube / round tube) and high-quality casters with brakes, finished with a sprayed plastic coating.

Drive methods include:

• O-type belt

  

• Multi-wedge belt

  

• Chain

  

The equipment can be custom fabricated according to customer requirements.

4. Transportation and Handling

• Upon receiving the equipment, promptly inspect the outer packaging for damage.

• If damaged, take photos immediately and have the delivery personnel jointly confirm the damage.

• If damage is confirmed, contact our customer service promptly.

• Use a forklift suitable for the equipment weight during handling and pay attention to safety.

• Avoid dropping, collisions, and heavy pressure during transport.

---

5. Installation Precautions

• Do not install in areas exposed to water to prevent motor short circuits and frame rust.

• Do not install in areas with flammable or explosive gases to prevent fire.

• Avoid installing in direct sunlight to prevent affecting motor heat dissipation.

• Avoid installing in areas with chemical or corrosive gases to prevent equipment damage.

---

6. Electrical System

• Pay attention to the power requirements indicated on the nameplate; install a voltage stabilizer in areas with unstable voltage.

• Single machine 220V Do not use the power supply 1 wire 380V Add the live wire 1 Method for connecting one grounding wire.

• Be sure to connect the grounding wire before use; power cables must meet standards and not be too thin.

7. Basic Control Box Operation and Wiring Diagram

7.1 Pre-startup Inspection

Inspect the following items and requirements before startup:

a. Confirm the correct power connection.

The control box indicates single-phase power connection 220V voltage; connect three-phase power to three-phase 380V voltage.

b. Confirm proper grounding.

7.2 Start and Operation

Steps for startup and operation are as follows:

a. Twist open the emergency stop switch on the control box.

b. Rotate to select the forward or reverse switch.

c. Adjust the speed potentiometer on the panel.

8. Troubleshooting Methods

8.1 Power indicator on the control box is off, motor does not run

Troubleshooting methods

• Check for loose or poor connections in the power supply.

• Check whether the power supply is live.

• Check if the air switch inside the control box has tripped.

8.2 Power indicator on the control box is on, but motor does not run when the knob switch is turned to forward/reverse

Troubleshooting methods

• Check whether the emergency stop switch is pressed.

• If the emergency stop switch is pressed, rotate it clockwise to restore the running state.

Fault cause

• The emergency stop switch has been pressed.

On the electrical control box at 8.3, the power indicator light is on, but the motor does not run when the knob switch is turned forward/reverse, and the emergency stop switch is not pressed.

Troubleshooting steps

• Check the upper right area of the inverter panel. RUN Check whether the light is illuminated.

• If RUN If the RUN light is on, check whether the potentiometer (black speed-adjusting knob) frequency is set correctly.

• Rotate the speed-adjusting knob clockwise to increase the frequency to its maximum before testing again.

Cause of malfunction

• The frequency has been set too low or reset to zero.

8.4 Error codes displayed on the inverter panel

Resolution

• Please contact the manufacturer’s technical staff.

8.5 Safety requirements during equipment repair or maintenance

• When repairing or maintaining the equipment, disconnect the power supply and ensure safety before working.

9. Inspection and maintenance

• Equipment usage 3 After three months, inspect screws/wire terminals for looseness; if present, tighten the screws promptly.

• During shutdown, check whether any foreign objects are between the belt and driven rollers; if so, clean them to avoid affecting equipment lifespan.

• Regularly inspect the power supply cables for damage; avoid forklifts or personnel stepping on the power cord during operation to prevent safety incidents.

• When retracting the equipment, be mindful of the power cable location to prevent it from being clamped by the telescopic plates.

• When operating the equipment, avoid inserting hands into the telescopic plates or belt.
