(yellow): the unit has shut down due to overtemperature condition. current limit (yellow): the unit is overloaded and operating in current limit. status signals the following are the optically isolated open-collector signals: fault : the unit has detected an internal fault. overtemp. warning : the unit is overheating; shutdown is imminent. power fail warning : the output of the power unit will fail in 5 ms.
