do not operate.

The unit may be repaired only by a Loctite authorized service technician.

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.

1.4 Field of Application, (Intended Usage)

This Loctite® ZETA® 7735 UV Curing Wand System is designed for use with light cure

products that cure when exposed to ultraviolet and/or visible light. The system can be

operated manually or in the timed mode and is capable of interfacing with a PLC

controlled unit.

2. Description

2.1 Theory of Operation

The ZETA® 7735 UV Curing Wand System utilizes a focused halide lamp and a liquid

filled light wand (supplied separately). The unit will operate on 115/60 Hz. or 230/50 Hz.

input power. A voltage selector switch is located on the back of the enclosure. When the

unit is switched on, the proper electrical power is immediately supplied to the lamp. It

will take several minutes for the lamp to reach full power. Once the lamp has reached full

power the unit is ready to cure adhesive. Curing will take place when the UV light is

directed at the liquid adhesive. Engaging the foot switch opens the shutter and the UV

energy produced by the lamp is immediately transmitted through the flexible light guide.

The time required to complete the curing process depends primarily on the offset distance

from the end of the wand to the surface of the adhesive and the type of adhesive being

used.

The exposure time can be controlled in either the manual mode or the timed mode.

Depressing the foot switch operates the manual mode. The shutter will remain open as

long as the foot switch is engaged. In the timed mode, setting the countdown timer from

zero to 99.9 seconds controls the exposure. The timed exposure starts by momentarily

engaging the foot switch. This action begins the timer and the shutter will remain open

until the countdown timer reaches zero. The ZETA® 7735 can also be actuated by

external devices using the foot switch 9 pin D connector and making a dry-contact relay

closure across pins 1 and 9.
