LABOPORT Pumps and Systems 

 

Troubleshooting 

Translation of original Operating Instructions, english, KNF 121211-121345 01/10

10.3. System with two Vacuum Controllers 

 

See also chapter 10.2, system with one vacuum controller.

 

 

System does not work, despite one Vacuum Controller (both controllers) being set on 
"Regulation Mode" 

Cause 

Fault remedy 

In the electrical supply unit the 
connecting wires for the vacuum 
controllers are plugged in incor-
rectly. 

  Exchange the plugs between vacuum controller 1 and vac-

uum controller 2. 

In the electrical supply unit the 
connecting wires for the vacuum 
valve are plugged incorrectly. 

  Exchange the plugs between vacuum valve 1 and vacuum 

valve 2. 

 

Tab. 35 

 

10.4. Fault cannot be rectified 

If you are unable to determine any of the specified causes, send 
the pump to KNF Customer Service (see page 47 for the address). 

1.  Flush the pump to free the pump head of dangerous or ag-

gressive gases (see chapter 9.2.1, page 37). 

2. Remove 

the 

pump. 

3.  Clean the pump (see chapter 9.2.2, page 37). 

4.  Send the pump to KNF with a filled out decontamination decla-

ration (see chapter 12) and specification of the medium trans-
ferred.
