WARNING:
WARNING
Contact Crouse-Hinds Airport Lighting for assistance prior to operating
a failed fixture. There may be dangerous voltage present on the input AC
pins of the power supply.
It is recommended that a ferro style constant current regulator (2.8 to
6.6A
RMS
) with a 10/15W isolation transformer or a voltage limited
constant DC current source be used to test failed fixtures to limit the
input voltage.
A buzzing or humming noise coming from the isolation transformer may
indicate a failed power supply or LED module. It is also an indicator of
dangerous voltage on the primary and secondary sides of the
transformer.
NOTICE:
NOTICE
Applying a constant voltage greater than 50V (AC or DC) to the input
will cause damage to the power supply.
Applying input current to the power supply without the heater or jumper
installed will cause damage to the power supply.
Follow the steps in section 9.7 to open the fixture and remove the top power supply as required. The power
supply continuously monitors the status of the LED module. There is a green status LED (see
that may be visible through the potting. The LED will not be visible in P2 or B1 configured fixtures
without removing the top power supply. A blinking LED indicates the power supply has detected a fault
condition.
