INDEXING TWINSPIN™ (1 MOTOR) OPERATING INSTRUCTIONS

• The Indexable TwinSpin™ is a twin rotator for two gobos driven from one motor and can be ﬁtted with one or two gobos. The

gobo on the ﬂat side of the rotator is fully indexed and the second gobo follows all the actions of the ﬁrst one in reverse.

• Four 10-position switches are on the control box. The MODE switch is the one nearest the Gobo end of the motor box. The

switch farthest from the gobo is X1 DMX address the X10 and x100

• There are ﬁve programmable DMX controlled modes and four built-in pre-programmed effects which don't require a DMX signal.

• The GAM indexing rotator is controlled by the DMX512 protocol and is powered by 24 volts DC, either from most

color scroller power supplies or a standalone power supply. *

• Once powered, the unit will show a red power LED to indicate the power is on. The unit is also ﬁtted with a green LED which

indicates the status of operation.

• At power on, the unit needs to initialize to ﬁnd the home position of the Gobos. This takes about 2 seconds during which

time the green data LED will ﬂash. Once the home sensing is complete, the ﬂashing will stop. If the green data LED is not lit,

then there is no DMX signal present. If the LED continues ﬂashing, it means there has been a fault detecting the sensor. The

unit will operate but without the correct index positioning.

• Mode and channel switches can be operated with the power

on. A small delay will take place to correctly accept any new

settings on the switches.

• The Gam indexing rotator is powered from most 4 pin color

scroller power supplies or a standalone power supply, 24 volt

DC and controlled by DMX 512.

INSTALLING PATTERNS - Install the patterns in the Gobo holders using the provided retaining rings. Older warped patterns should

be installed with the bent parts bowed away from each other so they won't catch when rotating. You must 'Burn in' new patterns

before rotating for the ﬁrst time by placing the TwinSpin™ (with the patterns mounted) in the ﬁxture and the lamp at full for approxi-

mately two minutes. Do not rotate the gobos. Failure to 'Burn in' will most likely result in a jam. If the patterns catch on each other

or the retaining ring is not properly secured and slips, the TwinSpin™ may jam and stop turning. Turn off motor and light as soon as

possible and remove the unit to free the jam.

PREPARE THE FIXTURE - Before installing the TwinSpin™ in the ﬁxture, it is important to align the lamp. The circle of light

should be as smooth and even as possible, without hot spots.

INSTALLING THE TwinSpin™ - Slide the TwinSpin™ straight down into the iris slot (the wide slot right in front of the pattern slot).

Make sure it is seated straight and as far down as it will go. Secure the 4-pin cable so that it does not contact the hot lamp house.

Please Note; The TwinSpin™ is not intended for use in the older 1000W ellipsoidal spotlights. For continuous applications we

suggest the new cool beam units such as the ETC Source IV, the Altman Shakespeare or the Strand SL and other

cool beam type units.

* The connections via the 4-pin XLR connector are as follows;

Pin 1 -24 V DC

Pin 4 +24 V DC

Unit will function properly on reversed polarity (as found on some color changer supplies).

Each unit has a male XLR input connector and a female XLR (with power and DMX signal feed through) allowing daisy chaining

multiple TwinSpins™ and scrollers on one line.

The current draw of the unit is about 500ma. If using many units on one supply, make sure the total current draw of TwinSpins™

and scrollers does not exceed the supply limits. As well, make sure the 4-pin cables (especially at the beginning of the chain) can

handle the load.
