Controls and Operation
The Zeta
®
7401 system is easy to use and requires only that the power be switched on to
operate. A panel meter is located on the back of the power supply to keep track of the operating
time accumulated on the unit. A new lamp should be installed at 1,000 hour intervals. If the lamp
is replaced in anything other than 1,000 hour increments, a record of the last hour meter reading
should be kept.
Parts should be centered in the parts drawer when curing.
UV lamps also emit heat energy that is usually insignificant, however, if heat sensitive parts are
being processed, a sample part should be tested by exposing it to a cure cycle. Reducing the
amount of time the part is in the drawer will limit the part heating.
The UV power should be monitored regularly using a radiometer (Loctite
®
98001). A reading
should be taken when the new lamp is first ignited so subsequent changes in the UV output can
be identified. Measurements should be made using the same type of radiometer, and preferably
the exact same instrument.
