6. What To Do In Case Of Breakdowns?
Problem Possible Causes Remedy
Pump doesn't start; • Power supply interrupted • Check fuse in the power pack unit
None of the integrated LEDs • Check plug contacts on the power pack unit
glow on the TC 600 • Check power pack unit feeder line
• Check voltage on the power pack
unit (140V 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 remote plug
plug not connected
• No supply of operations voltage • Check plug contacts on the power pack unit
• Defect TC 600 • Inform PFEIFFER Service of need for repair
• 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
start-up time; • Seek leak and repair
Pump cuts out during • Supply of process gas too high; reduce
operations • Rotor sluggish caused by • Check bearing (noises?): Request
defective bearing PFEIFFER Service to replace
• TC start-up time too short • Set longer start-up time with the DCU or PC
• Thermal overloading caused by:
– Insufficient water flow • 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
• Leak or too high a gas load • Seek leak in the system and repair
• Process gas supply too high; reduce
• Lubricant or lubricant
pump dirty • Carry out lubricant change as per
Section 8.1. or clean the lubricant
pump as per Section 8.3.
• Lubricant deficiency • Check lubricant and replace as necessary
Pump doesn't attain final pressure • Pump dirty • Bake out pump
• If seriously contaminated: Request
PFEIFFER 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 Service of need for repair
• Rotor damaged • Inform PFEIFFER Service of need for repair
• Splinter shield (if fitted) not • Check seat of splinter shield
seated firmly (see Section 3.2.)
Red LED on the TC 600 glows • Collective malfunction • Reset via mains OFF/ON or remote pin 5
• Different malfunction display
with a DCU possible
Red LED on the TC 600 blinks • Warning from: • Different warning display
with a DCU is possible
– Mains power failure • Ckeck power pack voltage
• Check the power pack mains connection
– Supply voltage short
circuit to earth • Check the power pack unit voltage for short
