OPERATION
This is a current sink 1-10V dimming operation. For current sink dimming, the left-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 left hand RJ45 connector on the rear of the luminaire
using pin outs as detailed below. Note that only the left hand RJ45 connector can be used for
current sink dimming.
