<SET> button
The SET button on the MMB300 maintenance mode box functions exactly like on the
EFB300 external function box.
The SET button can be used to activate test mode of the MMB300 maintenance mode box.
This means that the "MAINT Out" and "DO1" outputs can be manually activated or
deactivated. This allows you to check whether the outputs are functioning correctly and the
wiring is correct.
