01Safety Instructions

Earthing MandatoryIt is important to ground the yellow/green conductor to earth in order to avoid electric shock. Do not touch any wire during operation as high voltage might cause electric shock. Disconnect main power before replacement or servicing.

Unpack and check carefully that there is no transportation damage before using the unit.
Before operating, ensure that the voltage and frequency of the power supply match the power requirements of the unit.
The unit is for indoor use only. Use only in a dry location.
The unit must be installed in a location with adequate ventilation, at least 50 cm from adjacent surfaces. Be sure that no ventilation slots are blocked.
Make sure there are no flammable materials close to the unit while operating, as it is a fire hazard.
Use a safety cable when fixing this unit. Do not handle the unit by taking its head only, but always by taking its base.
Maximum ambient temperature is Ta: 40 °C. Do not operate where the temperature is higher than this. Unit surface temperature may reach up to 85 °C. Do not touch the housing bare-handed during operation. Turn off the power and allow about 15 minutes for the unit to cool down before replacing or servicing.
In the event of a serious operating problem, stop using the unit immediately. Never try to repair the unit yourself — repairs carried out by unskilled people can lead to damage or malfunction. Please contact the nearest authorized technical assistance center and always use the same type of spare parts.

WarningTo prevent or reduce the risk of electrical shock or fire, do not expose the unit to rain or moisture. Do not open the unit within five minutes after switching off. The housing, the lenses, or the ultraviolet filter must be replaced if they are visibly damaged. There are no user-serviceable parts inside the unit.

1.1Installation

The unit should be mounted via its screw holes on the bracket. Always ensure that the unit is firmly fixed to avoid vibration and slipping while operating. The structure to which the unit is attached must be able to support 10 times the weight of the unit; also always use a safety cable that can hold 12 times the weight of the unit. The equipment must be fixed by professionals and must be installed out of the reach of people.

05Trouble Shooting

Following are a few common problems that may occur during operation, with suggestions for easy troubleshooting.

A. The unit does not work, no light and the fan does not work

Check the connection of power and the main fuse.
Measure the mains voltage on the main connector.
Check the power-on LED.

B. Not responding to the DMX controller

The DMX LED should be on. If not, check DMX connectors and cables to see if they link properly.
If the DMX LED is on and there is no response on the channel, check the address settings and DMX polarity.
If you have intermittent DMX signal problems, check the pins on the connectors or on the PCB of this unit or the previous one.
Try to use another DMX controller.
Check whether the DMX cables run near or alongside high-voltage cables, which may cause damage or interference to the DMX interface circuit.

C. One of the channels is not working well

The stepper motor might be damaged or the cable connected to the PCB is broken.
The motor drive IC on the PCB might be out of condition.

Chapter 06

06Fixture Cleaning

The cleaning of internal and external optical lenses and/or mirrors must be carried out periodically to optimize light output. Cleaning frequency depends on the environment in which the fixture operates: damp, smoky or particularly dirty surroundings can cause greater accumulation of dirt on the optics.

Clean with a soft cloth using normal glass cleaning fluid.
Always dry the parts carefully.
Clean the external optics at least every 20 days.
Clean the internal optics at least every 30/60 days.

Disconnect from Mains before CleaningThere are no user-serviceable parts inside the unit. Do not open the housing or attempt any repairs yourself. In the unlikely event your unit requires service, please contact your nearest dealer.
