What to do if I see Exhaust TEMP HIGH ALARM on my Ulvac LR Water Pump?
If you see an 'Exhaust TEMP HIGH ALARM' on your Ulvac Water Pump, lower the environment temperature. Additionally, if the exhaust pressure is high (>0.13Mpa), clean and wash the exhaust pipe (Reverse-valve).
What does it mean when my Ulvac LR Water Pump displays RS232C ERROR?
If your Ulvac Water Pump displays an 'RS232C ERROR', it indicates a communication error between the controller and the main PC. Try improving the device side noise environment and strengthening the grounding line.
What does it mean when my Ulvac LR Water Pump displays MBP CURRENT E ALARM?
If your Ulvac Water Pump displays an 'MBP CURRENT E ALARM', it means the inverter alarm has been activated. Turn on the breaker. Avoid exhaust immediately after start-up, because high load operation at startup does not reach the steady rotation within the specified time.
