The ITU (blue) LED does not
light up.
The ITU main switch is off.
Turn on the ITU main switch:
The control-command cable is
not correctly plugged in or wired.
This can be tested by switching
on the ITU MAINTENANCE
ONLY button:
If the ITU (blue) LED lights up,
the problem is related to the
control-command link.
If the control-command cable is
new and has never been tested,
check its pinout.
If the cable was working before,
check its ITU and BFU
connections and check its
integrity: you should get a
+12VDC voltage between pin 9
and pin 1.
The ITU internal AC/DC power
supply is faulty.
