cannot cause overload conditions since they are equipped with intrinsic power monitor -
ing systems. The AIR CLEANING SYSTEM fans also have this function.
Figure 3 - Overload Behavior
Heavy Overload (including short-circuit)
Heavy Overload is defined as application of a load which causes a reduction in voltage
below 13V. This causes the power supply to enter HICCUP operation where power is
supplied for 2 seconds and then shuts off for 18 seconds. This procedure is repeated
until the short-circuit or overload is resolved, see Figure 4 Short-Circuit Protection HIC -
CUP Mode . For this condition, the maximum length of the power cables between the
power supply and the powered devices guarantees the behavior of a short-circuit down -
stream of this cable.
