Section 12: Capacitor Voltage Indication
Safety Warning
This unit holds a number of large capacitors for storage of the energy
required during the Strobe’s flash duration. These capacitors may be
charged with voltages up to 185Vdc. Associated with each capacitor is a
red indicator LED. When lit, this indicates the capacitor voltage is 50V or
higher. When power is removed from the module the capacitors
automatically discharge to 50V within 30 seconds.
Do not attempt any maintenance or wiring until the capacitors have been
allowed time to discharge to a safe level and all the red indicator LEDs
have gone out.
Section 13: Strobe Driver Diagnostic LEDs
The two Strobe Driver modules each have three indicator LEDs.
LED 2 and 3: Each is driven from one of the driver’s three outputs. Therefore
normally each one should blink at the same rate as the Strobe output. These
indicate the driver module is operating. If for some reason some of the White
LEDs in the Flash Head do not operate yet these diagnostic LEDs do blink, this
would indicate the fault is not with the Driver module. Should one or more of
these LEDs be stuck on or not flash at all, this may indicate a fault with the driver
module.
LED 4: Lights continuously when the Strobe is energized to show that an excess
of 50V is present at its output. If this does not light it might indicate either the
Driver module is faulty or not receiving any power.
Section 14: Red Beacon Driver Diagnostic LED
LED 1 on the Red Beacon Driver indicates more than 50V is present on the
output and gives a good indication that the Beacon Driver module is working.
