Two Light Bars
rFb
320mA
During the
simultaneous portion
of the
flash pattern,
320mA
is split equally
between the two light bars, and again
between left and right modules in each light
bar, resulting in 80mA per module.
During the
wig-wag portion
of the pattern,
the EMS automatically reduces the current
to one half (160mA) which flows through
one side of both light bars or the other side
of both light bars. The current splits equally
between the light bars, so each module
receives
80mA
.
To avoid damaging LED-enhanced signs, do not exceed the following maximum intensity settings based on the
fixture configuration and flash pattern:
Maximum Intensity Setting (mA) for LED-Enhanced Signs
Flash Pattern and Fixture layout
Yellow or White LEDs
Red LEDs
Steady-on
Single or Series
260
340
0.5s on 0.5s off
Single or Alternating
520
700
Dual Unison
1040
1400
0.1s on 0.9s off
Single
1040
1040
Dual Unison
1400
1400
These maximum settings will result in very bright signs and should not normally be required.
The intensity is pre-set at the factory based on your requirements and installation location, which are typically
discussed at the time of ordering. Should the installation location or situation change, you can adjust this setting.
Please contact Carmanah Customer Service prior to making any adjustments.
Intensity adjustments are 20mA per step.
The maximum output current of the LED driver is 1400mA.
The minimum output current of the LED driver is 40mA. AAA, ALC and Night Dimming features
will not reduce the LED current further.
As mentioned in Flash Pattern in this Section, odd numbers of round beacons must be set to a
unison or the 05A3 flash pattern to ensure all LEDs are powered equally.
When programming intensity for
RRFBs or ITE-compliant circular beacons
, minimum current
settings must be applied. Contact Carmanah for guidance.
