11 Troubleshooting 

11.1 Common malfunction list 

This centrifuge is designed with self-diagnosing function. For example, an error code of 

the fault found will be displayed at the right bottom corner of the screen.

 

 

WARNING:

 Do not open the door when the rotor is rotating. 

 

Table 11-1 Error code

 

Symptom 

  Causes 

Solution 

Nothing  appears  on  the 

screen  when  the  power 

is turned on. 

·Power socket blackout. 

·The fuse is blown out. 

·Remove  the  trouble  and  power 

again. 

·Replace the fuse.

Door Open 

·The door is open while the rotor 

is rotating. 

·The 

  button  is  pressed 

while the door is open. 

·Close the door immediately. 

·Close  the  door,  and  then  press  the 

  button. 

E-03 

Rotor ID 

The  centrifuge  can  not  identify 

the rotor ID. 

Reconfirm  the  ID  code  of  the  rotor 

and make a correct selection. 

E-04 

Temp Ctrl 

·Refrigeration ability is insufficient 

·The  air  inlets  on  both  sides  of 

the centrifuge are blocked. 

·Too  much  dust  is  deposited  on 

the radiator. 

·Something  is  wrong  with  the 

refrigeration parts 

·If the room temperature is high, lower 

it. 

·Dredge  the  air  inlets  on  the 

centrifuge. 

·Clean the dust. 

·Replace the damage part. 

E-06 

Over Set 

The  setting  speed  or  g-value  is 

over the allowable range. 

Check the settings and let it within the 

allowable range. 

E-08 

No Rotor

E-09 

Imbalance 

·The  imbalance  is  over  the 

allowable range. 

·The  machine  is  shocked  during 

operation. 

·Balance  the  sample  to  ensure 

imbalance  is  within  the  allowable 

range. 

·Don

’t  push/move  the  instrument 

when it is running.

Read Maintenance manual. 

Contact 

our 

sales 

or 

service 

representative. Inform them the alarm 

code. 

 

Error code E1 to E9 is mainly related to misoperation. User can continue using the 

centrifuge after the malfunction is removed.
