Troubleshooting vibration isolation platforms centers on quickly pinpointing the root cause: 80% of pneumatic isolation faults relate to the air pressure system, while 80% of active isolation faults relate to alarm codes. Most common faults (insufficient air pressure, leaking air hoses, loose sensor connections) can be handled on site by the user; complex issues such as internal air-chamber faults, actuator damage, and sensor calibration failure require LeadTop technical support. Preventive maintenance is key: for pneumatic isolation, check air pressure weekly, inspect air hoses monthly, and check filters quarterly; for active isolation, run a self-check weekly, calibrate sensors every six months, and schedule an annual professional inspection.
80% of the causes relate to the air pressure system.

Can Be Handled by User? |
|
Slowly dropping air pressure |
Observe the air pressure gauge reading |
Locate the leak (apply soapy water to fittings and look for bubbles); tighten or replace hoses |
✅ Yes |
|
Air hose fitting leak |
Apply soapy water to fittings and look for bubbles |
Tighten the fittings or replace the O-rings |
✅ Yes |
|
Aged / cracked air hose |
Visually inspect the hose |
Replace the hose (rubber hoses in service for more than 2 years should be replaced) |
✅ Yes |
|
Equipment overload |
Verify the total equipment weight |
Reduce the load or switch to a higher-capacity platform |
✅ Yes |
|
Aged air spring |
Air pressure is normal but the tabletop still sinks |
Contact LeadTop to replace the air spring |
❌ No |

|
Loose connection cables |
Re-seat the connectors |
Tighten all sensor connection cables |
✅ Yes |
|
Damaged cable |
Visually inspect the cable |
Replace the sensor cable |
⚠️ Partially |
|
Oxidized connectors |
Visually inspect connector contacts |
Clean the contacts with alcohol |
✅ Yes |
|
Faulty sensor |
Measure the sensor signal (multimeter or oscilloscope) |
Contact LeadTop to replace the sensor |
❌ No |
Pneumatic isolation platforms are themselves extremely quiet (nearly silent once the air film forms); the noise usually comes from the supporting compressor.
|
Noise Source |
Troubleshooting Method |
Solution |
|
Internal compressor noise |
Touch the compressor housing to feel vibration; listen at different points |
Contact the compressor supplier or LeadTop after-sales service |
|
Solid-borne transmission amplification |
Check whether the compressor touches the tabletop or wall |
Move the compressor >2 m from the tabletop and add vibration-damping pads |
|
Air hose vibration |
Check whether the hoses collide with hard objects |
Secure the hose routing and avoid contact with hard objects |

|
Blocked leveling air line |
The leveling line has a small inner diameter (2–4 mm) and is prone to moisture or debris buildup |
Blow the leveling line clear in reverse with dry air |
✅ Yes |
|
Worn or stuck leveling valve |
The leveling valve makes abnormal sounds or responds slowly |
Contact LeadTop to replace the leveling valve |
❌ No |
|
Air pressure fluctuation |
Observe the compressor start/stop frequency |
Find the leak or replace with a higher-capacity compressor |
⚠️ Partially |

Core Troubleshooting Direction |
|
Pneumatic isolation |
Tabletop fails to float, tabletop sinks, leveling failure, increased noise, degraded isolation performance |
80% related to the air pressure system |
Air pressure gauge, hoses, filters, air springs |
|
Active isolation |
E01–E08 alarm codes; abnormal isolation performance (no alarm) |
80% related to alarm codes |
Troubleshoot per the error code table |
|
Passive isolation |
Tabletop sway, equipment sliding, noise |
No air supply; no electrical system |
Aged isolators; improper selection |
|
