ACT Fresnel 50 WW
Maintenance
The operator has to make sure that safety-related and machine-technical installations are to be
inspected by an expert after every year in the course of an acceptance test.
The following points have to be considered during the inspection:
01) All screws used for installing the device or parts of the device have to be tightly connected and
must not be corroded.
02) There may not be any deformations on housings, fixations and installation spots.
03) Mechanically moving parts like axles, eyes and others may not show any traces of wearing.
04) The electric power supply cables must not show any damages or material fatigue.
The ACT Fresnel 50 WW requires almost no maintenance. However, you should keep the unit clean.
Otherwise, the fixture's light output will be significantly reduced. Disconnect the mains power supply and
then wipe the cover with a damp cloth. Do not immerse in liquid. Wipe lens clean with glass cleaner and
a soft cloth. Do not use alcohol or solvents.
The front lens will require weekly cleaning, as smoke fluid tends to build up residues, reducing the light
output very quickly.
Keep connections clean. Disconnect electric power, and then wipe the DMX connections with a damp
cloth. Make sure connections are thoroughly dry before linking equipment or supplying electric power.
Replacing the Fuse
Power surges, short-circuit or inappropriate electrical power supply may cause a fuse to burn out. If the
fuse burns out, the product will not function whatsoever. If this happens, follow the directions below:
01) Unplug the unit from electric power source.
02) Insert a screwdriver into the slot of the fuse cover. Turn the fuse holder counterclockwise. The fuse
holder will come out.
03) Remove the used fuse. If brown or unclear, it is burned out.
04) Insert the replacement fuse into the holder where the old fuse was. Reinsert the fuse cover. Be sure to
use a fuse of the same type and specification. See the product specification label for details.
Troubleshooting
This troubleshooting guide is meant to help solve simple problems.
If a problem occurs, carry out the steps below in sequence until a solution is found. Once the unit

05) If you are unable to determine the cause of the problem, do not open the device, as this may
damage the unit and the warranty will become void.
06) Return the device to your Showtec dealer.
No Response to DMX
Suspect the DMX cable or connectors, a controller malfunction, a light effect DMX card malfunction.
01) Check the DMX settings. Make sure that DMX addresses are correct.
