Strobe White Driver Diagnostic LED's
The two Strobe White Driver modules each have three indicator LED's.
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 LED's in the Flash Head do
not operate yet these diagnostic LED's do blink, this would indicate the fault is not with
the Driver module. Should one or more of these LED's 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.
Red Beacon Driver Diagnostic LED
LED 1: Indicates more than 50V is present on the output and gives a good indication
that the Beacon Driver module is working.
Microcontroller Board Diagnostic LED's
LED 1 (Red) on the Microcontroller board shows the status of the Flash Head. In white
mode, it will flash the driver number of any white drivers that currently have faulty
strings. In red mode, it will flash once every two seconds if the red current is low and
twice if the current is too high. It will not flash at all when all drivers are operating
properly.
LED 2 (Green) on the Microcontroller board pulses once every time a flash is initiated in
the Flash Head.
NOTE: Verification of the above may only be required if a communications Alarm is sent
to the Master Controller
Translator Board Diagnostic LED's
When power is applied to the Power Supply there are 3 LED's labeled ISO 5V, 12V and
5V that must be solidly lit. The LED labeled Watchdog must be blinking.
Once communications from the Master controller has been established there 3 LED's
that will Blink in unison.
These are TX_EN, TX 1 and RX 1
NOTE: If these are not blinking then there are no Communications.
NOTE: SW1 must be to set to position 0 when used as an AOL
