What 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.
What causes Edwards STP-301 to display CONTROLLER OT?
The Edwards Water Pump displaying 'CONTROLLER OT' indicates overheating inside the STP control unit. This can be due to a high ambient temperature or insufficient cooling of the STP control unit. Ensure the ambient temperature is 40°C or less and remove any obstructions from the ventilation port.
What to do if Edwards STP-301 Water Pump displays DISTURBANCE?
If the Edwards Water Pump displays 'DISTURBANCE', it may be due to an abnormal magnetic bearing or excessive external vibration. This can happen if the STP pump and control unit have different serial numbers, or if the cable length has been changed. Use units with the same serial number or perform tuning. Also, remove any external vibration to prevent it from affecting the pump. Check the piping and ensure no atmospheric air flows into the pump. Install the pump in a way that prevents foreign particles from entering.
Why is Edwards STP-301 showing PUMP OVERTEMP?
The Edwards Water Pump may show 'PUMP OVERTEMP' due to overheating inside the STP pump. This can be caused by overheating during baking, insufficient cooling, leakage in the vacuum piping system, or repetitive start/stop operations. Set the baking heater temperature to 120°C or lower and always cool the STP pump during baking or gas suction. Check the piping system for leaks, and be aware that repetitive start/stop operations may cause overheating.
How to fix Edwards STP-301 cable disconnect issue?
To fix a cable disconnect issue with the Edwards Water Pump, ensure the STP connection cable is correctly connected and securely locked.
What to do if Edwards Water Pump breaker goes OFF when powering ON?
If the breaker goes OFF when powering on the Edwards Water Pump, it may be due to an abnormal power voltage, specifically if 200V is applied to a 100V spec STP control unit. Set the voltage to 100 to 120V +/-10%.
What to do if Edwards STP-301 Water Pump power lamp does not light?
If the "POWER" lamp does not light when powering on the Edwards Water Pump, ensure the power cable is correctly connected. Also, verify that the power voltage is set to the correct range: 100 to 120V +/-10% (for 100V spec) or 200 to 240V +/-10% (for 200V spec). Finally, check whether a power failure has occurred.
Why Edwards STP-301 Water Pump ACCEL lamp does not light?
If the "ACCEL." lamp on your Edwards Water Pump does not light, consider the following: * If in MANUAL operation, press the "SELECT" switch until the LCD displays "LEVITATION" or "BRAKE ***00rpm." * Ensure the "MANUAL/REMOTE" changeover switch is in the correct position. * For REMOTE operation, check and replace any blown fuses (F1 to 4) for remote signal input. * Verify the correct setting of DSW-B No.4 according to the remote input connector/terminal.
