EMS warning lights
Reb EMS rotax 915is 3A (specifically
I'm interested in gaining a deeper understanding of the EMS warning light system. My question is not concerned with the advised pilot action in the event of lights illuminating.
I'm more interested in confirming the specific reasons that cause lights to flash, or showing fully on, what the ECU is monitoring in each case. E.g., Generator zero output, irregular output, etc
Why? I have also noted that within my Rotax manual it details flashing lights as indicative of less serious issues. but within the easy read chart it confirms the same action as stated within, e.g the POH's of the Bristell B23 and JMB Aviation VL3 both detail flashing A & B as the most serious of issues (both generators failed and use of battery backup to run the engine).
Ive also read that both lights may come fully on even when they are outputing 12 volts, indicating any reason between LOPC up to IFSD (there is no detailed description within the rotax manual of what LOPC or IFSD are, let alone the in-between reasons).
