Ans.:
1. Check if there is any air leakage of unit.
2. Check if Fan motor is running in correct direction and if the Iron net is stocked.
3. Check if Heater and thermocouple is ok, and use Device to get Electrical current value.
4. Check if there is resin gathering around Right side of unit and inside dust collector chamber.
5. Check if Contactors, temperature controllers, EGO, and Thermocouple is OK.
Ans.:
1-1 Check Air volume of Fan Motor from its 90 degrees Outlet port. 1-2 Check if Electrical current and resistance of Heater is Normal. 1-3 Check if Both Temperature Indicators, Up and down, share Same value. And also check if Frequency of ON/OFF is Normal. 1-4 Check if there is Spreader Cone inside Drying Chamber of unit. 2. Hopper Dryer is NOT Fulfilled with Material. 3. Check if there is any air leakage of the unit. 4. If possible, please try another brand of Material to check if our unit is working OK. 4-1Setting temperature is not High enough, please increase it. ( For example, ABS sets at 80℃, try to increase to 85℃, 90℃, and so on. and Ensure Material is not gathering together cause of High Temperature.) 4-2 Drying time may be Not long enough, please increase drying time. 4-3 Special Material, pellet is tiny and dense, we would suggest to have a special device to ensure material is dried completely and loading in orders.
Ans.:
1. Check if Capacitors and Wiring are Burned. 2. Check if Voltage of Factory is Normal and Stable. This is because Differences between 3 Phases of Voltage would also damage the unit.
Ans.:
Check if Wirings of Fan Motor, Heater, and inside control box are in good condition, not damaged or peeled, because this would lead Electric to steel cover to cause Electric leakage.
Ans.:
Set Temperature to do Automatic calculation or Adjust PID value manually.
Ans.:
You would see ① Indicator of SB is ON and ② Displayed FFF or - -
Ans.:
Positive and Negative Pole of Thermocouple are not connected correctly. Positive Pole connects RED wires. Negative Pole connects BLUE wires.
Ans.:
Check if Power cable is damaged or broken. Motor overload protector triggered.
Ans.:
1.Check if Switch of Fan Motor is connected correctly. 2.Check if lack phase of Motor. Lack phase of Motor would lead Motor is Not Running although switch of Fan Motor is ON. And Heating is ON to lead smoke.
Ans.:
1. EGO protector triggered. 2. OP protector triggered. 3. Replace with New lamps.
Ans.:
1. Adjust the air damper of stainless suction probe. 2. Clean or replace the paper filter. 3. Check the air hose of auto-loader is whether damaged. 4. Examine the limit switch, contactor overload, timer, and motor running well or damage. 5. The belt of blower for TC-6 Loader is loosen or broken. 6. Check the tube or material hose is plugged. 7. Power insufficient.
Ans.:
IC board malfunction to cause the line. # ③ & ④ discounted. PS. OL – Motor overload, PS - no carbon brush.
Ans.:
Check the Limit Switch disconnected.
Ans.:
IC board or buzzer breakdown to cause the IC board malfunction.
Ans.:
1.If suction hopper equipped on the hopper dryer and find the plugged of air outlet of hopper dryer, cause the material is unable to fall by pressure increasing. 2.Happen the static. (must do grounding) 3.Find the bridge or suction full of material in the suction hopper. (please reserve enough space)
Ans.:
1. Check if there has a control signal. 2. Check if relay is plug in and the control signal of relay can not match the specification. (Be sure the signal at the customer is DC-12V, DC-24, and AC-220V) 3. Check if press TIMER key already.
Ans.:
Check if the motor, gear, screw sets is block or not. Also check the motor wire connector, IC board and converter…etc.
Ans.:
No material or screw is broken.
Ans.:
1. Check if the IC board is away from high frequency area. 2. If still can not solve the problem. Please make sure the brand of converter then chooses a suitable converter.
Ans.:
Adjust converter to reduce the time.
Ans.:
Check if the output is at 0-10V, and the signal is connected. Wire of ＋－ is on right connection.
Ans.:
Check if the motor, gear, screw cylinder is block or not. Also check the motor wire connector, IC board and converter…etc.
Ans.:
Because the material is not smooth, the speed sometimes gets faster or slower. The solution of this problem is to use no testing hole cylinder or adjust the converter.
Ans.:
This is a linear problem. As our MF linear is a straight line. The customer’s extruder linear is curve so our MF can not reach this extruder.
Ans.:
1. The tooling / mold pipe lines are plugged, cause the pipeline deposit excessive carbon and block the pipe filter. 2. Improper select wrong mold temperature controller that not meet customer needs. 3. Lack of flow & electricity. 4. Find the fault of heating element, contactor, temperature controller.
Ans.:
1. Find the stuff like as iron filing that stay inside of pipeline to cause the leaking oil. 2. Improper or over usage this unit standard range.
Ans.:
1. Check the tank shall have sufficient water. 2. Connect correct of cooling water inlet and outlet. 3. Check whether plugged of cooler. 4. Check error of solenoid valve or temperature controller. 5. Regularly clean or replace the filter.
Ans.:
Check the pressure if there is no or insufficient to cause the water flow is short of water outlet to mold.
Ans.:
1. Happen this condition by mixing with oil and water and then heating. Suggest to replace new kerosene (oil) and clean the pipeline. (Be careful to check the water vapor inside of wheel. 2. If air left in the pipeline to cause the kerosene emitted and even burned out the heating element.
Ans.:
Malfunction of cooling fan, temperature controller, buzzer or indicator light leaking electricity to cause the fuse burned out.
Ans.:
1. Find no loop or block or lack of kerosene (oil). 2. Excessive deposition of carbon to cause heating element smoldering. 3. Error of EGO (overheat preventer), spot welding death of contactor, malfunction of temperature controller.
Ans.:
Molding machine of user is unable in operation, because from the leakage electricity of pump and heating element.
Ans.:
1. The temperature wave large. (ex. easy to reach 150℃ and down to 130℃) 2. Inside with vapor. (mixing with oil and water, visual recognition finds the oil muddy or not.) 3. When find the water inside must be drawn to all of the oil, and then refilled with new oil. 4. Be attention of heating element when you refilling new oil to prevent the smoldering of heating element. 5. If your roller machine is high speed rotation about 500 RPM, 20 ~30 RPM per minute will cause the centrifugal and the oil will not be able to fully send out. Please couple with outside with friction pump to drawn the oil from the inlet of mold temperature controller.
