CONNECTION - FOR 0-10V(CURRENT SOURCE)OPERATION
This is a current source dimming and decorative wheel operation. For current source, the inputs
to the COMET require an external control voltage between 0V and 10V DC.
There are three/four connections required – the fibre port, the 0-10V cable(s) and the power
supply cable. The fibre port should be connected first before the mains supply. Connect and
secure the fibre optic connector into the collar and the front of the unit and secure using the
M5 knurled locking screw. Ensure the fibre optic connector is fully inserted before tightening
the locking screw.
Never run the luminaire with the fibre optic connector out of the collar.
Wire up and connect RJ45 plugs to the RJ45 connectors on the rear of the luminaire using pin
outs as detailed below. The le hand RJ45 connector controls dimming, the right-hand connec-
tor controls the decorative wheel motor. Ensure the 0-10V control system is powered up and

Consult the Troubleshooting and Operation sections in this manual if the Comet does not
power up or operate as expected.
0-10V NOTES
• This is a current source 0-10V control system. The input from the 0-10V controller (source)
supplies a varying control voltage between 0 and 10v to the luminaire to control the dimming
or decorative wheel motors, or both the dimming and the decorative motors
• Always use an approved CAT5 cable
• With no 0-10V input the luminaire will give no light output and the decorative wheel will be
stationary, but may move slightly. If this movement causes a problem, connect a 0-10V
controller set to 0V or set the Comet to manual control.

CONNECTION - FOR 1-10V(CURRENT SINK)OPERATION
This is a current sink 1-10V dimming operation. For current sink dimming, the le-hand dim-
ming RJ45 socket of the Comet provides current flow to a remote electronic dimmer. The re-
mote electronic dimmer modifies the current returning to the Comet, thus providing remote
dimming control.
There are three connections required – the fibre port, the 1-10V cable and the mains supply
cable. The fibre port should be connected first before the mains supply. Connect and secure the
fibre optic connector into the collar and the front of the unit and secure using the M5 knurled
locking screw. Ensure the fibre optic connector is fully inserted before tightening the locking
screw.
Never run the luminaire with the fibre optic connector out of the collar.
Wire up and connect a RJ45 plug to the le hand RJ45 connector on the rear of the luminaire
using pin outs as detailed below. Note that only the le hand RJ45 connector can be used for
