Fixture setup
The onboard control panel lets you configure the fixture using a range of fixture settings. Note that many of
these settings are also available on the Control / settings DMX channel (see “Adjusting settings via DMX” on
page 23).
Fixture ID
The fixture lets you set a four-digit ID number to ease identification of the fixtures in an installation. When a
fixture is powered on for the first time, it displays its DMX address by default. As soon as you set an ID
number other than
0
in
FIXTURE ID
, the fixture will display this ID number by default, and indicate
FIXTURE
ID
in the display.
Personality
The
PERSONALITY
menu provides several options that let you customize the fixture for different
applications:
• The
PAN/TILT
menu offers the following options:
-
PAN INVERSE
and
TILT INVERSE
let you invert the direction of pan and tilt movement. This can be a
fast way of setting symmetrical action in multiple fixtures with no need to reprogram cues.
-
FOLLOWSPOT MODE
disables the pan and tilt motors so that you can move the head manually using
the integrated handles on the back of the head.
Warning!
The head becomes hot during use. Make sure that it is impossible for operators to burn
themselves.
When you disable followspot mode, the fixture resets pan and tilt and the head returns to its original
position.
The pan and tilt motors are completely disabled to give the smoothest head movement with maximum
freedom, but you must support the head constantly while in followspot mode (unless you apply
TOGGLE HOLD POSITION
in the shortcuts menu as described below). If you let go of the handles, the
head will sink under gravity to a tilt down position.
- Using the shortcuts menu that opens if you hold the MENU button pressed in for 2 - 3 seconds (see
“Shortcuts” on page 13), a followspot operator can quickly put the fixture into followspot mode and also
use the
TOGGLE HOLD POSITION
feature. Applying
TOGGLE HOLD POSITION
while the fixture is in
followspot mode uses the pan and tilt motors to hold the head in its current position. This menu item lets
the followspot operator quickly toggle between free head movement and static head position.
-
LIMIT PAN/TILT
lets you define minimum and maximum limits for pan and tilt angles so that you can
install fixtures close to obstacles (such as other fixtures or trusses) with no risk of collision, so that the
beam will only hit a certain area of a stage or set, or so that you can avoid the fixture shining into the
eyes of the audience.
PAN MIN
and
TILT MIN
set minimum limits for pan and tilt, and
PAN MAX
and
TILT MAX
likewise set
maximum limits. The fixture’s pan and tilt movement will remain in a ‘safe zone’ within the limits that you
set.
- To set the limits using the control panel menus, go into the
LIMIT PAN/TILT
menu and enter the
minimum and maximum limits for pan and tilt as the 16-bit values that you would use to move pan
and tilt to those positions via DMX. The range of values available is -32767 to 32768.
- To set the limits via DMX, move the head using the pan and tilt DMX channels to the position where
you want to set minimum pan and tilt limits, then enable
Pan minimum
and
Tilt minimum
limits on the
Control/Settings DMX channel, sending values for at least 1 second to activate them. Use the same
method to set the maximum pan and tilt limits.
Note that when you power the fixture off, the head may move under its own weight to a position that is
outside its pan and tilt limits.
RESET PAN/TILT LIMITS
sets the fixture to default pan and tilt limits that are suitable for mounting the
fixture in a GT Pre-Rig truss using standard Martin half-coupler rigging clamps. If you install the fixture
in this type of pre-rig truss, you only need to execute a
RESET PAN/TILT LIMITS
command and set
LIMIT ENABLE
to
ON
to avoid the risk of head collisions.
