To Next PageTo Next PageWhat to do if Edwards STP-301 has POWER FAILURE?
If the Edwards Water Pump experiences a power failure, first check if a power failure has actually occurred. Next, ensure the power cable is correctly connected. If the cable is damaged, replace it. Finally, verify that the power voltage is set correctly to 100 to 120V +/-10% (for 100V spec) or 200 to 240V +/-10% (for 200V spec).
Why does my Edwards STP-301 Water Pump show OVERLOAD?
The Edwards Water Pump may show an overload due to a motor driver overload. This can be caused by insufficient pressure at the inlet or outlet port, leakage in the piping system, or failure of the backing pump. To resolve this, ensure you are using the maximum working pressure or less, and the allowable backing pressure or less. Inspect the piping system for leaks and check the backing pump's capacity and start state, using a pump with the recommended capacity or more.
How to troubleshoot insufficient ultimate pressure in Edwards STP-301?
To troubleshoot insufficient ultimate pressure in your Edwards Water Pump, check the following: * Inspect the backing pump for its capacity and start state, ensuring it meets the recommended capacity. * Examine the piping system for any leaks. * If residual molecules are present, and the main composition is H2 or H2O, perform baking. If it's other than H2 or H2O, clean the inside of the vacuum equipment.
