Dymax EC-Series Flood Lamps for UVCS Conveyors User Guide
Preventing Unit Overheating
Dymax EC-Series UV-Curing Flood-Lamp models do not possess an automatic shut-off capability in the event of
the Lamp Reflector Assembly overheating. The Ignitor within an EC Lamp Reflector Assembly, under certain
conditions, may overheat to a point where the Ignitor itself can melt, char, or smoke if the unit continues to
operate while in an overheated condition. Adjacent materials and components, such as fiberglass insulation
and insulated wiring, may show heat and/or smoke associated discoloration or degradation. The following
checks will reduce the risk of overheating Ignitors within the Lamp Reflector Assembly:
1.
Replace Bulbs at the recommended 2,000-hour service intervals, or before the intensity falls outside
of the application requirements. A degraded or damaged Bulb increases the risk of arcing, or can
create an excessive current draw on the Ignitor which can raise the internal temperature of the
Ignitor.
2.
Dymax recommends that only Dymax-branded OEM Bulbs be used in the EC Lamp Reflector
Assemblies. Some after-market or inferior quality Bulbs are built to different specifications which may
deteriorate more rapidly, leading to an increased burden on the Ignitor, and associated internal
temperature increase of the Ignitor.
3.
Confirm that the Bulb orientation is correct, and has been properly seated into the Lamp Sockets.
A secure Bulb should not move freely in the Lamp Base. Lightly try to move the Bulb laterally,
longitudinally, and rotationally to ensure the Bulb contact areas are fully seated with the Socket
contacts.
NOTE:
Always use a soft, clean lint free towel, clean paper towel, or gloves when handling the Bulb.
Skin oils left on the Bulb will burn into the quartz, reducing output intensity. If the Bulb is inadvertently
touched, clean the Bulb thoroughly with a soft, clean lint free towel and alcohol. Refer to the user
manual enclosed within the unit for complete instructions.
4.
Inspect Lamp Sockets for any signs of arcing, physical, or heat-related damage, and replace if needed.
Inspect closely, as the Lamp Sockets are ceramic and may have a hairline crack that may not be
noticeable from afar.
On the 5000-EC, the Lamp Socket is partially hidden by the Reflector material. The Reflector may be
removed by the 4 Screws on the bottom of the unit to allow for a more detailed inspection.
5.
As with any machinery or equipment, general preventive maintenance should be performed to
ensure the equipment continues to perform as intended. Wear components, such as Fans and Lamp
Socket Assemblies, should be replaced routinely.
Lamp Socket Assemblies should be replaced every 4 Bulb changes.
Fans should be replaced every 5 years or 50,000 hours of ON time.
For severe duty applications (e.g. units that are running under 24/7 operating conditions, or harsh
ambient condition), replacements should be considered every 4 years, or 40,000 hours. Please
contact a Dymax Repair Center for service needs.
