Electrical Safety
High voltage and current energize the UV Lamp. A high-
voltage Power Supply and Igniter combination is designed
to provide lamp-starting voltages, to limit current, and
subsequently provide a uniform output of energy.
NOTE:
To avoid the risk of electrical shock, do not attempt
to replace the Lamp before turning off the Power Input
Switch, and disconnecting the Input Power Cord.
The electrical system of this unit
should be serviced
by qualified service personnel.
High Temperatures
Due to the high output power of this system, high
temperatures may be present on the surfaces of the Lamp,
Reflector, Lamp Head, and Headrest.
NOTE:
Extreme care should be taken to prevent touching
any of the surfaces before allowing sufficient time for all
temperatures to drop to safely back to room temperature
after power has been removed.
The Lamp Head Assembly should never be placed on or
near any flammable surface while the Lamp is on, or before
its temperature has cooled back to room temperature.
Never place the Lamp Head or parts to be cured on a heat-
sensitive surface. Always cure parts on a metallic or non-
flammable surface. When the unit is not in use, place the
Lamp Head on the Headrest and switch the standby switch
to the low power position to minimize temperature rise.
WARNING!
Placing the Lamp Housing
Assembly on or near flammable surfaces while
the Lamp is on or still hot could result in fire.
Shielding
All installations should incorporate adequate shielding of
radiated UV light in order to prevent eye and skin burn of
the operator or others passing through the work area
(refer to the UV safety warnings in the safety
considerations section of this manual). The supplied
Headrest/Curing Chamber can be used with the
PORTA-RAY 400R to minimize the amount of stray UV
light scattering in the work area. Custom shielding may be
constructed using sheet metal or UV-blocking acrylic or
polycarbonate to prevent operator exposure to UV
radiation.
WARNING!
To prevent risk of eye or skin burn,
all personnel must be protected from direct or
indirect exposure to the UV light produced by the PORTA-
RAY 400R light-curing system. Extreme care should be
used when designing custom UV shielding to ensure
personnel will not be exposed to harmful UV radiation.
Additionally, UV protective glasses and protective clothing
should be used at all times while working in the vicinity of
the UV light-curing system.
Product Overview
Description of the PORTA-RAY 400R
The PORTA-RAY 400R light-curing system may be placed
on any bench or shelf that has access to an 115 VAC
50/60-cycle single-phase power source in a clean
operation area.
CAUTION:
The PORTA-RAY 400R is available in 115 VAC
and 230 VAC configurations. The unit’s voltage
configuration is clearly identified by a bright orange label,
located adjacent to the unit’s AC power input connector at
the side of the Lamp Head. Operating with voltage outside
the specified range will result in damage to the system.
Since the PORTA-RAY 400R is an air-cooled unit, dust or
airborne particles can clog the internal cooling passages
and cause overheating. Allow a 4-inch clearance on all
sides of the Lamp Head during operation for unrestricted
airflow.
System Components
•
Mounting Holes (A) -
Two threaded holes that can be
used for fastening the Lamp Head to a fixture, machine,
or conveyor.
•
Input Power Switch & Receptacle (B) -
Input Power
Switch used to apply or remove main power to the
PORTA-RAY 400R system. Co-located with the Input
Power Switch is the IEC-type Receptacle where the
Input Line Cord is inserted.
•
Handle (C) -
The PORTA-RAY 400R Handle can be
used to carry the curing system when the Lamp Head
