Frequent alarms and shutdowns during operation (over temperature/low liquid level/abnormal pressure)?

Fault phenomenon: The equipment suddenly stops, and the display screen shows alarm codes such as "E1 overtemperature", "E2 low liquid level", "E3 abnormal pressure", etc.

Core reason: Overtemperature alarms are often caused by sensor malfunctions, temperature controller loss of control, or cooling system failures; Low liquid level alarm is caused by medium leakage and blockage of liquid level sensor; Abnormal pressure alarms are often caused by blockages in the circulation system or shutdowns in the circulation pump.

Solution: Interpret the alarm code according to the equipment manual; Supplement the medium for low liquid level alarm and clean the sensor probe; Overtemperature alarm: Turn off the heating function. After the temperature drops to a safe range, check the sensor and cooling system; Abnormal pressure alarm: Clean the filter and check the circulation pump. After troubleshooting, press the "reset" button to restart.
