The Spectra UV cure module is designed with up to six UV lamps, depending on the
configuration. There can be a maximum of three lamps on the top and three lamps on the
bottom. The Configuration section of the Operating Guide gives the number of lamps the
module is programmed for. The module must have at least one lamp. Any unused lamp
slots are covered by a metal plate. Lamps can be activated and deactivated in Setup mode.

its place to protect the operators and the surrounding environment from UV light.
