PROBLEMS RELATED TO IME244 : Verify the status of the LED on the IME244. The LED that indicates a fault on the board itself are only the two green leds on top-right part of the board, that signalize the presence of 12V D.C and 24V A.C for the heaters (these leds are present in TX and RX boards). All the other leds (present only on RX board) show the alarm/disqualifying status that arrives them from other technologies in the pillar (IR, MW, Doppler). These Leds in normal conditions must be in OFF. If they’re in ON verify why the relative technology has generated the alarm (follow the previous tables).
