5 Operation5.1 Controls and Operation☞The Zeta ® 7401 system is easy to use and requires only that the power be switched on tooperate. A panel meter is located on the back of the power supply to keep track of the operatingtime accumulated on the unit. A new lamp should be installed at 1,000 hour intervals. If the lampis replaced in anything other than 1,000 hour increments, a record of the last hour meter readingshould be kept.Parts should be centered in the parts drawer when curing.UV lamps also emit heat energy that is usually insignificant, however, if heat sensitive parts arebeing processed, a sample part should be tested by exposing it to a cure cycle. Reducing theamount of time the part is in the drawer will limit the part heating.The UV power should be monitored regularly using a radiometer (Loctite ® 98001). A readingshould be taken when the new lamp is first ignited so subsequent changes in the UV output canbe identified. Measurements should be made using the same type of radiometer, and preferablythe exact same instrument.4
6 TroubleshootingSymptomLamp does not light, power switchdoes not light, and fans do not start.Lamp does not light, powerswitch lights, fans are running.UV Output is low,(Radiometer Reading)Poor or Slow Cure ResultsCorrective Action/Possible Cause1. Make sure the system is plugged in.2. Check the fuse in the power cord receptacle.1. Make sure that the lamp is plugged in.2. Lamp is at end of its life.3. Check that the connector cord is properly installedat both ends.1. Reflector needs to be cleaned.2. Lamp is at end of its life.3. Lamp needs to be cleaned.4. Check radiometer accuracy, calibration.1. UV output is low, (see above).2. Product is not compatible with the lamp type.3. Position lamp closer to the part.5
