Loctite CL15 UV, Руководство по эксплуатации

Страница: 4 / 22

1. Please Observe the Following (continued)
Caution!
Never turn the unit on without the lamp connected to the power supply.
Caution!
The energy emitted from the end of the light guide can heat any surface that it is
directed at. Care must be taken to determine the proper offset distance and exposure
time.
Caution!
Turning the lamp on and off frequently will cause the UV output of the lamp to
decline at a faster rate. It is recommended that the unit be left on during breaks and
short down times.
Caution!
Avoid making sharp bends in the light guide, as this will cause a loss of UV energy or
possibly cause permanent damage. To prevent permanent damage, the minimum
bend radii are 2.4 inches for a single light guide and 1.6 inches for a dual light guide.
The unit may be repaired only by a Loctite® authorized service technician.

Field of Application, (Intended Usage)
This Loctite® UV CL15 Wand System is designed for use with Loctite products that
cure when exposed to ultraviolet light produced by the unit. The UV energy is
directed towards the product through a liquid filled light guide that is ordered
separately. Several configurations of light guides are available from Loctite®,
including single and dual ended types. The unit is also capable of interfacing with an
external relay or PLC circuit.

Description
2.1
Theory of Operation
When the unit is switched on, electrical power is immediately supplied to the lamp and
ignition should occur within several seconds. As soon as the lamp has completed the warm
up cycle, an internal relay will change state, making a closure across pins 3 and 4 of the
footswitch connector, (located on the rear panel of the unit). The front panel display will
indicate the progress at the warm-up period. Curing takes place when the shutter is opened,
allowing UV light to be directed from the end of the liquid filled light guide to the adhesive.
The curing parameters, (UV irradiance and exposure time) must be determined before use.
The UV irradiance, (the strength of the UV light), at the adhesive surface can be varied by
adjusting the distance of the light guide from the bond. If the light guide is moved to within
½ inch of the adhesive surface, vapors from the curing process may build up on the end of
the light guide, reducing the UV intensity over time. The UV exposure time required to
complete the curing process depends primarily on the UV irradiance and the properties of the
adhesive product.
