3.2.5 OUTPUT CONTACTS CONFIGURATION

All output relays are form C relays. Only one of the two states of the form C relay is connected to the MIGII output
terminal. For each output relay it is possible to select which state is preferred to have at the MIGII terminals, NC (normally
closed) or NO (normally open).
Next figure shows the PCB of a MIGII relay, and the location of the jumpers used to select the configuration of each
output contact (NO or NC).
