often in a particularly heavily polluted atmosphere). Also, while changing the
lamps, a careful check should be made of the high voltage leads to make sure
that no deterioration has occurred. Dirty contacts may cause a potential
hazard.
Danger
Accessing and cleaning electrical components must be done only after the machine has
been shut down and disconnected from mains power.
High
Temperatures
UV system operates at very high temperatures and the inside components
become very hot during machine operation, which may cause personal injury.
Therefore, when maintaining the equipment, a reasonable time (15 minutes)
should be allowed before access is attempted.
Safety UV Curing
UV Radiation
UV radiation is generated from UV lamps and can be harmful if operator
exposure exceeds recommended levels (see
Permissible UV Exposure Levels
on page 17).
Danger
To avoid exposure, always work with the UV flaps in the "up" position (see
Figure 1-7
.
Figure 1-7 UV Flaps in the "Up" Position
All equipment is adequately guarded, shielded and interlocked to prevent
accidental operator exposure.
Equipment should be annually checked for UV radiation levels.
Radiation is in the wavelength bands A, B, and C. Exposure to UV radiation
can result in:
UV flaps
UV lamp housing
