Violux VT 4, 6 & 8 Rev. V 1.9 10/98 JC/GT File: VT Manual Warning !
Ultra-Violet Emission
THEIMER lamps emit ultra-violet energy as well as carbon arcs, mercury vapor and similar light
sources used in printing applications. The safety glass, which is furnished with all
THEIMER VIOLUX lamp housing, provides protection for the operator by filtering out
all UV B, wave lengths below 320 nm. Theimer Violux lighting systems use a DIN
(DIN 1249) certified safety glass which meets the stringent European safety
standards. Some Theimer self contained exposure systems are not equipped with
the safety glass but incorporate electrical safety interlocks. These interlocks should
not be defeated under any circumstance.
In all Theimer exposing machines UV A is present in the exposure area, as with
similar light sources used in printing applications. Operators must be instructed not to
look directly into the light source or stare at reflected light from the light source. They are not to work or
stand in front of the light source while it is exposing. UV protective curtains should be used to limit the
exposure to the operator and to prevent other sensitive materials in the work area from being fogged.
UNDER NO CIRCUMSTANCE should the THEIMER lighting system be operated without the
ORIGINAL SAFETY GLASS in place or SAFETY INTERLOCKS DEFEATED.
Should the safety glass break, it should be replaced only with a Theimer replacement glass.
CAUTION
Service
All servicing of Theimer lighting systems should be performed by an approved technician or
competent electrician. Several terminals within the lighting system carry high voltages and the unfiltered
lamp produces high doses of UV A, B & C. When servicing, care must be taken to protect the service
agent from the UV light generated by the lamp.

Violux VT 4, 6 & 8 Rev. V 1.9 10/98 JC/GT File: VT Manual DESCRIPTION
The VIOLUX 4002T, 6002T and 8002T Printing Light Systems feature metal halide lamps whose
spectral output matches the sensitivity of daylight films, sensitized plates and proofing materials. They
utilize a metal shutter to obtain short exposures by eliminating warm-up times and spectral shifts that
are normally associated with mercury vapor and "instant start" light sources.
The VIOLUX operates in a stand-by condition with the shutter closed until an exposure is to be
made. The shutter is opened by a light integrator or timer for the duration of the exposure. After the
exposure is completed and the shutter closes, the lamp remains lit so that it is immediately ready for the
next exposure. Optional Theimotrol II and Timetronic Light Integrators monitor the light intensity to
maintain exposure accuracy. Using the Power level push buttons on the Theimotroll II or the remote
control box , the operator can select the appropriate power level for their photographic materials.
VIOLUX Printing Light Systems are designed for mounting over a horizontal printing frame. A printing
lamp stand is available for use with vertical frames.
The installation and operation of the VIOLUX 4002T, 6002T and 8002T are identical and all units are
covered in this manual. Before unpacking and installing the equipment, it is suggested that this
instruction manual be read carefully.
