Night Mode
A number of options may be selected to determine how the light behaves when
in night mode. Either the Red Beacon or White Strobe can be chosen to come on
at night by means of the switches on the microcontroller board. When White at
night is chosen, it operates at 2000cd. The brightness when in White night mode
is not affected by the dimming inputs.
Red Beacon Flash Rate and Synchronization
The Red Beacon may either be flashed or steady burned. For steady burning
hold the Sync input terminal to the live terminal. For flashing either do nothing
with the Sync input (in which case the Beacon will flash at a default 20FPM) or
pulse the Sync input with 100-230Vac at the desired flash rate. The flashing will
synchronize to this pulsing. The flashing duty cycle is 50/50.
WRED Flashing Mode
The Wred flashing rate is; 1s light, 0.5s dark, 1s light and 1.5s dark. This may be
selected by means of a DIP-switch on the microcontroller board
White Strobe Flash Rate and Synchronization
Either do nothing with the Sync. input (in which case the White Strobe will flash
at a default 20FPM) or pulse the Sync input with 100-230Vac at the desired flash
rate. The flashing will synchronize to this pulsing.
Fault Signals
A fault is indicated if the microcontroller has detected a fault for 20 consecutive
flashes.
Two uncommitted solid-state relays provide indication of faults. One allows the
Red Beacon to be monitored and the other the White Strobe. The behavior of the
relays can be programmed using the DIP switch on the microcontroller board.
The relays can either be closed when a fault is detected, open on a fault or
pulsing when all is well. The latter mode is a fail-safe mode of operation.
If the fault clears, the fault signal will remain until power to the unit is cycled.
