• Switching on the projector

After carrying out all the above operations, press the switch (23) checking it all works properly.

At switch on, the software contained in the DMX Receiver microprocessor does a checksum (automatic check) while the three figure display (24) is off and the three LEDs (25) controlling the input signal are all on. After a few seconds, the projector starts the mechanical zero setting of the effects. At the same time, if the checksum has had a positive result, a code corresponding to the version of the DMX Receiver microprocessor (installed) appears on the display. This code is displayed for about 5 seconds, then only one of the three LEDs relating to the connected input signal stays on, while the following information scrolls on the display once:

Total hours - XXX Bulb hours - XXX Bulb strikes - XXX Address - XXX

in which “Total hours” is the total number of hours of the fitting’s life, “Bulb hours” is the number of hours of the lamp’s life, “Bulb strikes” is the number of times the lamp has been switched on and “Address” is the selected starting address for the projector control signals.

After the information has scrolled, the projector address will stay displayed.

The above information can also be displayed by carrying out at least one of the following operations:

•Setting all the DIL (Dual-In-Line) switches of the addresses (26) onto zero.

•Activating the TEST procedure, turning the specific DIL switch (27) ON.

•Setting the projector on blackout (20 channels starting from the selected starting address, all at level zero).

About two minutes after the projector has been switched on, the luminous intensity of the display (24) decreases to 1/32 of the maximum value. The maximum luminosity is restored automatically if you use the microswitches to select the DMX address, set the options or activate the TEST function. Approximately two minutes after the last operation listed above has ended, the luminosity of the display decreases again.

• Projector coding

Each GOLDEN SCAN 3 requires 6 or 8 control channels. For these to be correctly addressed to each projector it is necessary to code the projectors. This operation needs to be carried out on each GOLDEN SCAN 3 by switching the microswitches (26) according to the table below.

Codes can be assigned with the projector off, although the operation will be easier with the projector on, as the decade address corresponding to the binary code set with the microswitches is shown on the 3-digit display (24).

When the information of "Total hours", "Bulb hours”, “Bulb strikes” and “Address" is scrolling on the display and you use the DIL switches of the addresses (26), the display will instantly show the new address selected. After a few seconds the above information will start scrolling again if at least one of the above conditions remains.

Projector 1 - Channels	1-6	ON
		OFF
Projector 2 - Channels	7-12	ON

On turning the TEST microswitch (27) onto ON the projector runs a self-check, during which the effects are mechanically reset with the projector on. At the end of the operation, or whenever you want to interrupt this procedure, turn the TEST microswitch back onto OFF.

When sending 0% levels to all channels, the unit will start an automatic re-calibration after 2 seconds. This operation will reposition any effects to their correct settings.

The entire re-calibration cycle lasts approximately 35 seconds and can be stopped at any time by simply setting a channel at a level above 0. It is recommended not to interrupt re-calibration, but to let it end regularly, once 10 seconds have elapsed from its start.

4 MAINTENANCE

• Opening and closing the cover

Loosen the knob (28) and remove the re-lamping cover (18).

After maintenance refit the cover (18) and lock the knob (28).
