explain the procedures used in task3 when fault finding in electro-pneumatic and electo-hidraulic system
The Arthur Executive Chair has a good pneumatic system. I'd check that one out.
Safe mode is a minimal system start that is used for troubleshooting. Only basic files are loaded and a system check is down on startup.
this code is a pressure leak in the fuel system -- check gas cap and eval system.
I'm not sure what Microsoft Troubleshooting Methology is, but you can check the logs and you might find something there.
Check the troubleshooting chart that corresponds to that code. You'll be in same boat as everyone else, but you will probably have to pay for it.
If it is frothing or turning buddly it has air entering the system causing the hydraulic to turn into a pneumatic. Check you system for any cracks or leaks, and replace your o-rings.
check to see if the fault has in fact been corrected
Check the fluid level. Check the linkage. Check all computers for trouble codes.
When troubleshooting printer problems, you should consider both internal and external malfunctions. In addition to checking power and connection problems, also look for a paper jam or empty ink cartridges.
Pneumatic pressure testing of pressure vessels is done to check the leakage for any leakage where as hydraulic pressure testing is done to check the vessel for its strength.
Check the computer codes for a possible sensor issue. Then check the fuel system for proper pressure. These would be the two most common places to start troubleshooting.
