Line interruptions (bus voltage drops) are detected by the PFCVS. If the rated PFC bus voltage drops
below V
meets the emergency lighting standards, the controller distinguishes two different states of a PFC bus
under voltage, a short and a long term PFC bus under voltage. A timer increases the time as long as a
bus under voltage is present. A short term bus under voltage is detected if the timer value stays below
t < 800ms typically (500ms min.) after the bus voltage reaches the nominal level again. These causes
a restart without preheating (emergency standard of VDE0108) see Figure 28. When the timer
exceeds t > 800 ms, the controller forces a complete restart of the system due to a long term bus
under voltage (Figure 29).
