Passive Vibration Control Troubleshooting
The system is over-inflated.
For the manual load adjustment version, air can be let out of the system by pressing the core in the center of the Schrader valves. For the automatic load adjustment, reduce the air pressure in the system by adjusting the air regulator.
The system loses air quickly.
For the manual load adjustment system, check that the valve cores on the Schrader valves are not loose. If they are, tighten them using a Schrader valve core tool. If you hear the sound of leaking air, contact Herzan as there may be fittings or cabling underneath the table loose.
For the automatic load adjustment system, make sure there are no leaks or cracks in the hoses connecting the air supply to the regulator and the regulator to the system. Make sure all connection points are well-sealed. If you hear the sound of leaking air, contact Herzan as replacement items may need to be provided.
PLEASE NOTE: The air diaphragms on the system will need to be replaced every 3 – 5 years. Contact Herzan for replacement parts.
The system won’t float.
For the manual load adjustment system, you need to inflate the system using a hand pump and the Schrader valves on the front of the system. If you are having trouble inflating the system, check to make sure the hand pump is operating properly. Place your hand in front of the air pump nozzle and pump it, feeling if air is coming out of the air source. Also, check to make sure there is no debris clogging the Schrader valves from operating properly.
For the automatic load adjustment system, the system must be connected to an external air supply. Connect the external air supply to the air regulator and feed air into the air regulator. Also, ensure the air regulator is connected to the rest of the isolation system to feed air into the isolators. Check to make sure all the lines are attached properly and they are free from cracks or leaks.
If the above methods are ineffective, ensure that the load on top of the system isn’t exceeding the load capacity of the system. This information should have been provided in the original quotation or user manual provided with the table.
Vibration isolation performance is poor.
Ensure the system is ‘floating’ by confirming the system is properly inflated using the steps above.
Ensure that the system is placed on a sturdy and rigid table.
Check all cables connected to the equipment on top are slack and, if necessary, weighted.
Check the set-up is not influenced by acoustic noise or air movement. If so, employ an acoustic enclosure or wind baffle.
Make sure that equipment is centered on top of the isolation system.
