GAM Twinspin TS5574 - Manual (Page 2)

Tip: When using older warped patterns, be sure any
protruding edges are bent away from each other in the
TwinSpin™ so they can’t catch on each other while rotating.
CONTROL
The TwinSpin™ 6-step transformer can be plugged into
any 120 volt outlet (230 volts if you have 230 volt mod-
el) and patterns will rotate at full speed when the trans-
former is set to 12 volts. You can also set the step switch
anywhere between 3 and 12 volts to vary the speed, no
dimmer is required. Do not use the 1.5 setting as volt-
age fluctuations may cause the TwinSpin™ to stall. The
lowest setting should be 3.
Using a Dimmer
To easily start, stop, and adjust the rotation speed, plug
the TwinSpin™ into a dimmer. Most types of dimmers will
work, although speed range and resolution may vary. Elec-
tronic dimmers slightly clip the top and/or bottom of the
speed range, but offer good resolution. The best results are
produced by autotransformers.
TwinSpin™ with Built-in Speed-Control Model
If you have selected the TwinSpin™ with built-in speed
control you can plug the power transformer into an AC
line 120 volts or into a dimmer as well for control (230
volts if you have 230 volt mode). Using the potentiom-
eter you can vary the speed of the TwinSpin™ without
any other dimmer. The 6-step transformer allows you to
vary the speed as well and you can use the 6-step trans-
former to set a speed and then use the potentiometer to
more subtly slow it down for finer control. You can also
plug it into a dimmer.
BURNING IN PATTERNS
When using new patterns with a TwinSpin™, they must
be burned in slowly before rotating for the first time. This
is done by placing the TwinSpin™ (with the patterns in-
serted) in the fixture. Run the lamp at full for approximately
two minutes. Do not rotate the TwinSpin™. If the patterns
are not burned in before rotating, they might jam.
HANG-UPS
If the patterns catch on each other, or if the retaining ring
is not properly secured and slips, the TwinSpin™ may
jam and stop turning. Turn off the motor as soon as pos-
sible to prevent seizing. Remove the unit to correct the
problem, reassemble, then resume operation.

R EMOVING TWINSPIN™ FROM THE FIXTURE
It’s best to let the fixture and patterns cool naturally
before removing the TwinSpin™ from the fixture. Pulling
it out ‘hot’ will cause warping and possible tearing of the
patterns due to the quick temperature change.
1. Lift the TwinSpin™ straight out of the iris slot.
2. Make sure the handle of the pattern holder behind it
doesn’t press against the patterns and dent them.
REMOVING GOBOS (See Fig. 3)
1. Use a small pocket knife blade or flathead screw-
driver and pry the hooked end of the retaining ring out
of the groove IN toward the center, and UP.
2. Pop the ring out of the groove and remove ring and
pattern with your fingers.
QUICK CHANGES
If you need to change a hot pattern in your TwinSpin™,
be prepared with a hot pad or gloves. The elements
will be too hot to handle.
SPIN DESIGN
TwinSpin™ provides four design options. You may rotate
a single pattern, two patterns with the same design or
two different designs. The fourth option is to use one or
two rotating patterns to animate a ‘still’, which is placed
in the pattern holder. Refer to the GAM Catalog or visit
us online to see over 800 patterns available.
CAUTION!
TwinSpin™ is not intended for continual use in
older 1000W ellipsoidal spotlights. For continu-
ous operation applications we suggest the new
cool beam units such as the ETC Source IV or
the V Shakespeare.
