This read-write object sets the LNB's upper alarm current limit, valid between 50 and 600 mA. This threshold catches the opposite failure mode from the low-current limit -- an LNB drawing excessive current typically indicates a short, a failing internal component, or a cable fault, and this alarm gives an early warning before the condition escalates to a blown fuse or damaged feed line. If an LNB rated for roughly 150 mA normal draw suddenly shows its measured current climbing toward 500 mA, having this high-current limit set to something like 200 mA ensures the alarm fires well before the current approaches the connector or wiring's damage threshold.
