The MES9012 motherboard has six control signalling LEDs, which can be activated by setting DIP 12 on
the unit with 12 on the board to ON.
At the end of the test it is advisable to reposition the DIP on OFF, both to avoid catching the signals
and to reduce the system consumption.
POWER
Power supply on LED

with the disqualification intervention, the barrier is
excluded, which will become operational again as soon
as the fog has cleared.
HTR LED
LED confirming that the heating
system is on
Electronically controlled automatic heating system to
