Manual Effect Adjustments
Manual controls for effect intensity, color, motor speed, and motor direction are accessible at the rear of the
unit. Note that some or all of the manual trimmer controls may be inoperative when the fixture is operated in
DMX control mode. The selector switches for motor direction will operate as described in either manual or
DMX mode.
The LED intensity and effect motor speed controls are multi-turn potentiometers. These controls can be
adjusted using a small slot-blade screwdriver without opening the unit case. Rotating the controls clockwise
increases the setting, counterclockwise adjustment will decrease the setting. The controls are very precise,
and several turns may be required to produce a significant change. The controls do not stop or tighten at the
end of their adjustment range, but will continue to spin without causing any additional change at minimum or
maximum settings.
Changing Intensity
The fixture electronics have provisions for controlling two LED emitters, which are typically red and amber.
For each installed emitter, the intensity is adjusted by increasing or decreasing the setting of the matching
trimmer. The balance of color between two mismatched emitters, and the overall intensity of the fixture may
be adjusted to the users requirements by using these controls as necessary. The LED intensity controls are
non-functional in any DMX mode.
Changing Motor Speed
The two motor speed controls are used to adjust the rate of motion in the output pattern. The adjustment
ranges from slow enough to be barely perceptible, to very rapid and turbulent. For the most natural
appearance, both controls should be set from 5 to 7 turns from minimum. Higher or lower settings may be
used depending upon the display requirements. It is normal for the noise level from the effect motors to
increase at higher speed settings, but the motors will not be damaged by prolonged operation even at
maximum speed settings. Motor speed controls are non-functional in 3 or 4 channel DMX mode
Changing Motor Direction
Two switches control the direction of the two effect motors. Each switch controls one of the motors. The
switches can be set using a small slot-blade screwdriver or probe without opening the unit case. The
switches are accessible between the LED Intensity and Motor Speed controls on the rear panel of the fixture.
The switches are recessed to prevent accidental motor direction changes. Motor direction can be changed by
using a small screwdriver or probe to gently engage the switches, and move the switch toggle or rocker.
Avoid applying excessive force to the switches. Motor direction switches operate in all modes.
The motion of the projected effect can be significantly altered by changing the direction that the pattern
wheels rotate. Firelight units are shipped with both motors turning in opposite directions. Due to the
arrangement of the wheels, this produces an effect with either up or down motion, depending on the fixture
orientation. Upward motion produces the most realistic flame appearance, especially when the motors are set
at nearly equal speeds. Changing the direction of one motor will alter the pattern so that the effect motion
will be both upward or downward. If the resulting animation is not in the desired direction, i.e. up when you
want down, then changing the direction of both motors will correct the pattern motion. To obtain more
swirling, or interaction in the effect, one of the motors should be operated at a slightly faster or slower speed
than the other.
