6. What To Do In Case Of Breakdowns? 

Problem Possible 

Causes

Remedy

Pump doesn't start;

• Power supply interrupted

• Check fuse in the power supply

None of the integrated LEDs

• Check plug contacts on the power supply

glow on the TC 600

• Check power supply feeder line
• Check voltage on the power supply

(72 V DC) at connection X2

• Incorrect operations voltage supplied • Supply correct operations voltage
• Pins 1-3 and 1-4 on the remote

• Connect pins 1-3 and 1-4 on the

plug not connected

remote plug

• No supply of operations voltage

• Check plug contacts on the power

pack unit

• Defect TC 600

• Replace TC 600 (please see Sec. 7.2.)

• Reduction in the voltage in the cable

• Use suitable cable

Pump doesn't attain nominal 

• Fore-vacuum pressure too high

• Check backing pump function

rotation speed within the set

• Leak or too much gas

• Check seals

run-up time

• Seek leak and repair

Pump cuts out during operations

• Reduce supply of process gas

• Rotor sluggish caused by 

• Check bearing (noises?): Inform

defective bearing 

Pfeiffer Vacuum Service

• TC run-up time too short

• Set longer start-up time with the DCU or PC

• Thermal overloading caused by

– Water flow insufficient

• Ensure free flow

– Insufficient air supply

• Ensure adequate air supply

– Fore-vacuum pressure too high

• Reduce fore-vacuum pressure

– Ambient temperature too high

• Reduce ambient temperature

Pump doesn't attain final pressure

• Pump dirty

• Bake out pump
• If seriously contaminated: Request

Pfeiffer Vacuum Service to clean

• Leak in vacuum chamber, 

• Seek leak starting with vacuum chamber

lines or pump

• Repair leak

Unusual operating noises

• Bearing damaged

• Inform Pfeiffer Vacuum Service of need for 

repair

• Rotor damaged

• Inform Pfeiffer Vacuum Service of need for 
repair

• Splinter shield (if fitted) 

• Check seat of splinter shield 

not seated firmly

Red LED on the TC 600 glows

• Collective malfunction

• Reset via mains OFF/ON or remote pin 5
• Different malfunction display with the

DCU or HPU possible1)

Red LED on the TC 600 flashes

• Warning through:

• Different warning message with 

the DCU or HPU possible1)

– Mains power failure

• Check power supply voltage
• Check power supply mains

– Supply voltage short 

connection

circuit to earth

• Check power supply voltage for short

circuit to earth

• Wrong setting for nominal rotation 

• Enter 833 Hz for parameter 777 

speed (Parameter 777)

(see operating instruction PM 0547 BN
“Pumping Operations With DCU”). If there is 
no DCU/HPU available contact 
Pfeiffer Vacuum Service .

1) Without a DCU or HPU inform Pfeiffer Vacuum Service to check the cause of trouble.
