1.SCR overheat protection
Heat sink temperature is higher than 80 plus or minus 3 degrees C, the buffer will automatically stop or prohibit the start, and Err.1 red light flash.
2. To prevent the start due to the phase
If the main power due to start phase two is Err.1 red light flashes, and to prohibit start. (Mains K1, K2, K3, and then other components can not be, otherwise it will affect less the phase detection.
3. Reversing lock
Three-phase power to detect positive and negative phase sequence, you can choose to allow or permit the operation of reversing a single direction to prevent reverse the damage to the device by mistake. (If the phase sequence error, the Err.1 flashing red light c)
