CHAPTER 7 - MAINTENANCE

7.5.4

Separate the gliding support base when un-tightening the locking bolts between the gliding support and bottom frame.

7.5.5

When assembling the machine together, put the parts which are last taken apart back first and vice versa. But before the assembling, check the parts for wears and damage, replace.

7.5.6

Fix the part where is needed.

7.6 Easy damaged parts and provided tools for the machine:

Hood Spanner
1pc

Foundation Bolts
1 set

Buffer Block
6pcs

 

CHAPTER 8 - TROUBLE SHOOTING

8.1 Trouble shooting for electric parts

FAULT

CAUSES

METHODS

8.1.1

After loading the fabric and closing the lid, but the inner basket does not rotate;

(1)The emergency switch S1 do not reset, or not well connected;
(2)The coverlid is not well- connected, or damaged;
(3)Middle relay K1 is error;
(4)Timer relay T is on 0 position;

  Check the emergency switch S1;
  Check the coverlid switch;
  Check the middle relay K1;
Reset the running time of timer relay; Check or replace;

8.1.2

Entering into high speed from 0~50hz, but still not into the set max high speed, the machine stops suddenly.

(1)The set time of the timer relay t is too short;
(2)The accelerate time of the inverter is set too short;
(3) The inverter is fault.

(!) Examine the timer relay T;
(2) Reset the accelerate time of the inverter.
(3) Read the instruction manual for the inverter.

8.1.3

Reaching the set time of timer relay, but the machine does not stop by inertial force.

(1)Failure in power supply;
(2)The speed-down time of the inverter is set too short;
(3) The braking resistor or braking unit is fault.

  Check the power supply;
  Reset the speed-down time of the inverter.
  Check the braking resistor or the braking unit.

8.1.4

Unmoral heating of the braking resistor.

(1) The cooling fan of the braking resistor cabinet is fault.
(2) The IGBT mode of the inverter error.

(1) Replace the cooling fan.
(2)Check if the output of B1 and B2 of the inverter is 500V. If yes, the IGBT mode damaged, replace or repair the inverter. .

8.1.5

The IGBT mode of the inverter is damaged.

  The resistor pipes may be error.
  The cable may be fault.

  If the resistor pipes is burnt, replace it;
  If it is not grounded, do well insulation for it;
  Replace the damaged cable.

CHAPTER 8 - TROUBLE SHOOTING

8.2 Trouble shooting for mechanical parts

FAULT

CAUSES

METHODS

Great vibration on the machine

(1) Check the fixing screw for the buffers seat and blocks loose or not;

If loosen, tighten it.

(2) Check the buffer seat and block damaged or not;

If damaged, replace it.

(3) Check the fixing screw for gliding support seat loose or not;

If loosen, tighten it.

(4) Check the gliding support system damaged or not;

If damaged, replace it.

(5) Check the spindle nut loose or not;

If loosen, tighten it.

(6) Check the material loading if uniform;

If uneven, re-loading the material.
