Why does my S&A CWFL-800 Industrial Equipment show an ultra-high temperature alarm (E2)?
- JJennifer AndrewsAug 2, 2025
An ultra-high temperature alarm (E2) on your S&A Industrial Equipment can be triggered by several factors. First, check if the dust gauze is blocked and needs cleaning to improve thermolysis. Poor ventilation around the air outlet and inlet can also cause this, so ensure they are unobstructed. Other potential causes include extremely low or unstable voltage (in which case, improve the power supply circuit or use a voltage regulator), improper thermostat parameter settings (reset controlling parameters or restore factory settings), frequent power switching (ensure at least 5 minutes between power cycles for refrigeration), and excessive heat load (reduce the heat load or switch to a model with larger cooling capacity).
