B3, B2 and B1, B2 of the power supply unit interface and check
the voltage in the terminals. If no voltage is detected in these
terminals, the power supply unit interface may be defective. If a
voltage is detected, check that there is no short circuit in the
connections B3, B2 or B1, B2 between the devices of the installation.
With LED lit: check the voltage between terminals B3, B2 and B1,
B2. Disconnect terminals B3, B2 and B1, B2 of the power supply
unit interface and re-check the voltage in the terminals.
