  • 1.Temperature is NOT going up or did not reach required value.
    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.
  • 2.Material was not dried completely.
    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.
  • 3.Fan Motor is Faulty.
    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.
  • 4.Electric leakage
    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.
  • 5.Temperature is Going up and down in Huge differences.
    Ans.: Set Temperature to do Automatic calculation or Adjust PID value manually.
  • 6. Thermocouple is faulty.
    Ans.: You would see ① Indicator of SB is ON and ② Displayed FFF or - -
  • 7.Temperature keeps going UP and not stopping.
    Ans.: Positive and Negative Pole of Thermocouple are not connected correctly. Positive Pole connects RED wires. Negative Pole connects BLUE wires.
  • 8.No Temperature.
    Ans.: Check if Power cable is damaged or broken. Motor overload protector triggered.
  • 9.Smoke from Heater.
    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.
  • 10.Indicators are OFF.
    Ans.: 1. EGO protector triggered. 2. OP protector triggered. 3. Replace with New lamps.
  • 1.Unable to dehumidify. (Unstable dew-point)
    Ans.: 1. Check both of Dehumidifying dryer and Hopper dryer if they are suitable. 2. Check both of DHM (DHC) and HD if they have air leakage. 3. Check if the raw material contains oil or added. 4. The function of desiccant and honey comb rotor is unstable for dehumidify or regeneration. 5. Evaporator blocked, heating element fault or regeneration temperature is too low.
  • 2.Rotation error.
    Ans.: Check the spares of PU-TR, timer 60M x 12S, PU-NC, SENSOR, compressor air source…etc. Check it step by step to solve the failure.
  • 3.Overheat
    Ans.: It may EGO error or breakdown. Thermal bar poor assembling and poor contact causes overheat of temperature controller and SSR failure.
  • 4.Regeneration temperature unstable.
    Ans.: To replace temperature controller, auto computing and adjust PID.
  • 5.High temperature of regenerative air.
    Ans.: Check cooling water, filter, evaporator and cooler.
