IMPORTANT! DO NOT OPERATE THE UNIT BEFORE READING THIS SECTION.
WARNING!
Removing, bypassing or putting out of operation of the safety devices can result in
radiation damage to persons and damage to the unit and is therefore prohibited!
Damage to the power cord or the housing can result in contact with live electrical parts.
Check the power cord and the unit before each use. If the power cord or the unit is
damaged, do not operate! Replace a damaged power cord with a new one.
Disconnect power supply before opening the housing!
Never operate system while lamp housing is open!
High voltage is generated by the ignition capacitor inside the lamp housing!
The UVALOC System generates high-intensity UV radiation that, on direct exposure, can
damage skin and eyes in a short time.
In case of malfunctions in the regular operation of the shutter, avoid direct exposure of
the skin under all circumstances, in case of any other shutter malfunction, too!
Broken lamps will release mercury!
Proceed as follows:
Remove all persons at once from the immediate vicinity of the UVALOC System to
prevent breathing of mercury vapours. The room should be thoroughly ventilated
(15 – 20 minutes). When the unit has cooled down, mercury residues should be removed
using absorption systems available from specialty chemicals suppliers.
CAUTION!
The lamps contain mercury. Do not dispose with household trash.
Disposal as hazardous waste required.
To avoid injury, do not touch the shutter while cure chamber is open. This part may reach
up to 90°C during operation.
Only authorized Henkel service staff is permitted to open and repair the unit, except for
replacing the UV bulb and the air filter.

Ventilation
Cooling air is drawn through ventilation slots in the front panel of the unit, while hot air is
exhausted at the rear. Do not obstruct any of these air vents to make sure that ventilation
air circulates throughout the system. Obstruction of these openings or failure of the fan
will cause the unit to overheat. Replace the filter mat at regular intervals.
Explosive Zones
This unit is not specified for operation in explosive zones.
Earthquake Zones
If operated in earthquake zones, the unit must be securely fastened.

1.5 Special Instructions
Lamp Life
Based on an average power-on time of 8 hours per day and normal service conditions,
the lamp has an expected service life of
– Fe-doped 700 hours,
– Pure mercury vapour 1000 hours (standard lamp), and
– Gallium doped 600 hours.
The life time of the bulbs is valid only at the operating condition of 1000 W. They will be
much shorter at 500 W.
To prevent excessive wear of the bulb when operating at 500W, the bulb must be
operated at 1000 W daily for about 15 minutes.
☞
Note!
At 500 W the spectrum of the Fe-doped bulb is reduced to the spectrum of the Pure
mercury vapour bulb!
All bulbs contain mercury. Other dopings are available for special applications.
UV bulb intensity deteriorates gradually with time. Bulb life depends very much on length
of operating intervals, as each ignition process subjects the bulb to considerable wear.
☞
Note!
Frequent on/off switching results in premature deterioration of the bulb. Do not switch off
for idle periods of less than 3 hours.
How to Handle the Bulb
Any contamination which has not been removed, such as fingerprints on the glass, will
bake to the envelope and result in premature deterioration of performance.
☞
Note!
Fingerprints can be removed with a lint free wipe and pure alcohol. Before reassembling
the bulb into the unit the alcohol must have evaporated completely!
In rare cases the envelope may burst – especially if the bulb is very old. The reasons
could be etched fingerprints on the envelope or too frequent on/off switching.
WARNING!
Broken bulbs will release mercury.
Proceed as follows:
Remove all persons at once from the immediate vicinity of the UVALOC System to prevent
breathing of mercury vapours. The room should be thoroughly ventilated (15 – 20 minutes).
When the unit has cooled down, mercury residues should be removed using absorption
systems available from specialty chemicals suppliers.
Overheating
If the maximum operating temperature is exceeded the bulb is automatically switched off
and the shutter closes automatically. After the unit has cooled off sufficiently
(≤55 °C in the lamp housing) the lamp can be ignited again. Overheating may be caused
by obstruction of ventilation slots or excessively high ambient temperatures.
Repair and Servicing
Always disconnect power cord before opening the unit.
Before servicing, always let the unit cool down for 5 minutes. Do not attempt any repairs
except exchanging the bulb and filter mat, see section 8.3 and 8.4. Refer all other repairs
to an authorized Henkel service center.
WARNING!
High voltages are present inside the unit!

1.6 Field of Application (Intended Use and Foreseeable Abuse)
The UVALOC 1000 is a 1000 W lamp system designed exclusively for curing Loctite
®
UV adhesives or coatings.
It is prohibited to use UVALOC 1000 for drying or curing any other materials or for
heating any flammable or explosive fluids.
The radiation spectrum and performance provided is especially matched to the
requirements of Loctite
®
UV curing adhesives and coating materials, allowing UV
adhesives to cure rapidly to form a dry, non-tacky surface.
UVALOC1000 is a modular system. Version 97055 comprises a controller, a lamp
housing and a cure chamber. Version 97056 consists of only a controller and the lamp
housing.
UVALOC1000 has a pneumatically operated shutter. The time for opening /closing the
shutter is 1 second max. each, which achieves precise and repeatable curing results.
The cure chamber has four rack levels to accommodate the slide-in tray, allowing easy
positioning of parts of various heights at the level of optimum exposure. The tray is
designed as a perforated aluminium plate to allow positioning of customised part holders.
The lamp housing holds the UV radiation source with shutter, fan and ignition capacitor.
The controller module holds the control panel, the display, the power switch and the
selector switch for 500 W and 1000 W.
Provided that the shutter operates correctly, the UV bulb is effectively shielded,
eliminating any danger to operators during part loading or unloading. However, it is
recommended that persons with sensitive skin or eyes use gloves, long-sleeved clothes
and UV safety glasses.
The light proof design of the cure chamber ensures a high degree of occupational safety.

2 Description
2.1 Theory of Operation
UVALOC is a high-performance lamp system for curing UV adhesive. The chamber
version (97055) is a closed system. It is used for applications permitting manual loading
of the cure chamber
The tunnel version (97056) is the open type designed for integration into semi or fully
automated plants. Both versions offer capability for internal monitoring of the intensity of
UV radiation emitted by the bulb. This function provides additional safety in the
production process as lamp performance is monitored for each exposure.
The parabolically shaped reflector is usable for the most applications because the nearly
parallel radiation generates an uniformly illuminated radiation area.
In contrast the elliptical shaped reflector generates a line of radiation with high intensity
and is more suitable for the use in conveyer systems. The basis is here the tunnel
version 97056.
Radiation spectrum and performance provided by the lamp are especially matched to the
requirements of Loctite
®
UV curing adhesives and coating materials. Completely dry,
non-tacky surfaces can be achieved rapidly. Exposure times can be preset in 1 s steps to
ensure precise repeatability of curing results. Exposure time has to be determined by
testing to ensure precise results.
As with all UV bulbs of this type, the intensity of light will decline with time as the
electrodes deteriorate and burnt tungsten is deposited on the lamp housing.
The UV minimum output –which is necessary to cure and triggers a warning message
when this value is reached – can be set in the “UV MINIMUM” menu as percentage
value.
The condition for it is a calibration of the integrated UV meter with the bulb. The
”UV CALIBRATION” menu indicates the measured value in terms of percent, e.g. 105%.
This is an absolute value showing the intensity of the bulb. Do not calibrate after
replacing the bulb, to guarantee that the output of the new bulb can be compared with
the old one.
During the installation a measurement should take place with a separate UV measuring
instrument. The measuring should be made at the same position where the work piece
will be inserted into the chamber. An exact relation is received between the %-indication
and absolute intensity (in mW/cm²), for example 100% corresponds to 100 mW/cm²
UV intensity on this position.
However, if you should find out during production that the ”FELL BELOW UV MINIMUM”
warning message is displayed too early or too late, you can adjust the setting on the ”UV
MINIMUM” menu.
For better bulb control, the number of ignitions is recorded for each bulb. The count
should be reset whenever the bulb is replaced and the bulb operating hours as well.
The XS 2 interface is used for exchanging the actual system statuses with a higher-
ranking controller, see Section 9.2.
