| 1. Blower is rotating in reverse. |
|
|
|
Will occur if power cord connections are in reverse phase.
 |
 |
Start work after stopping operation and check that breaker is off.
Those who do not have sufficient mechanical/electrical knowledge should not do any maintenance work requiring disassembly or repairing due to risk of injuries and dangers of work. |
|
- Adjust hook-up for two of the three power cords from the main unit and turn breaker on.

| 2. Material/Suction Hose has a hole open or external air is being sucked in from packing area. |
|
|
|
Materials will not transfer if a hole is open on the hose or if the hose band is not securely tightened.
|
- Check hose to see if any holes (punctures) are open.
- If hose is damaged or punctured, replace with new hoses.
- Check to see if hose ends are securely fastened by the hose bands.
- Check to see if the packings are loose or wearing.

| 3. Inside of material hose is clogged. |
|
|
|
Hose will not convey material if clogged.
|
|
|
Start work after stopping operation and check that breaker is off.
Those who do not have sufficient mechanical/electrical knowledge should not do any maintenance work requiring disassembly or repairing due to risk of injuries and dangers of work. |
- Check the inside of the hose to see if materials are clogged.
*If clogged, remove material.
- Adjust the amount of air intake from the secondary air adjustment ring.
*If ring suction section (wire mesh) on secondary air ring is clogged, blow clean dry air to remove particles.

|
|
|
Materials may not vacuum properly if wire mesh filter in conveying filter collector is clogged.
|
|
|
Start work after stopping operation and check that breaker is off.
Those who do not have sufficient mechanical/electrical knowledge should not do any maintenance work requiring disassembly or repairing due to risk of injuries and dangers of work. |
- Check to see if either the conveying filter or the wire mesh in the collecting hopper is clogged or not.

| 5. Suction Hopper damper (jet clone type) is not securely closed. |
|
|
|
| If damper is not securely closed during conveying, materials will not convey. |
|
|
Start work after stopping operation and check that breaker is off.
Those who do not have sufficient mechanical/electrical knowledge should not do any maintenance work requiring disassembly or repairing due to risk of injuries and dangers of work. |
- Check to see if damper is closed while conveying
* Remove any material stuck on damper
- Check to see if damper arm is bent
* Replace with new part if arm is bent

| 6. 2-Way Valve not switching over normally |
|
|
|
| Materials will not convey if the 2-way valve does not function normally |
|
- Check air kit to see if dry compressed air (0.4MPa ~ 0.5MPa) is being supplied.
- Check to see if connector is securely hooked up.
- Check to see if 2-way valves are running normally
Click here on checking function
* If valves do not switch over after checking function, the 5-port solenoid valves may be defective
* If valves do switch over after checking function, the control panel may be defective.
If so, replace with new panel.
