Page 5: Introduction
® MultiBrite Operator's Manual INTRODUCTION The MultiBrite System is presented to fill the need for monitoring several UV light sources for the purpose of relaying a single alarm to an operator when any of the sources falls below the specified limit. A MultiBrite System is comprised of three major components, the Signal Conditioning Module, the Signal Conversion Module, and the Display Module, each of which will be described below. -

® MultiBrite Operator's Manual The alarms will not be activated if power has recently been applied to the system. A dip switch programmable time delay from 5 seconds to 21.25 minutes will ensure the lamps will be at full intensity before indicating an alarm condition. -
Page 7: Typical Clamp And Mirror Installation
® MultiBrite Operator's Manual Once a suitable mounting location is determined, a 7/8" diameter hole is drilled or punched in the side of the lamp housing. The clamp is mounted in this hole with the threaded side facing toward the inside of the housing. -

® MultiBrite Operator's Manual Figure 5B shows a similar installation with the UVISENSOR looking down at the top of the lamp through a 1/4" diameter hole. In this configuration, the UVISENSOR must look at the lamp and not beside it. This is to prevent the UVISENSOR from seeing reflections from the work surface below the lamp. -

® MultiBrite Operator's Manual Figure 5. Typical 45º Bracket Installation UVISENSOR Wiring The cable from the UVISENSOR must be routed to the MultiBrite in such a way so as to avoid contact with the moving equipment, workpieces, lamp bodies and lamp cabling. Use appropriate cable clamps or ties as necessary to secure the cable. -
Page 11: Cleaning The Uvisensor And Mirror
® MultiBrite Operator's Manual Cleaning the UVISENSOR and Mirror Whenever the UV lamp or its reflector are cleaned or replaced, the glass window of UVISENSOR should be cleaned at the same time. Before proceeding, turn OFF all power to the UV equipment and allow it to cool. Using a Q-tip dipped in denatured alcohol clean the glass window of the UVISENSOR and wipe it dry with a lint-free cloth. -

Caution must be exercised in connecting the signal loads to the system because the four connectors on the back panel are identically the same. For convenience, the signal wiring may be attached to the connector terminal strip before the connector is inserted into the mating back panel connector. -

Operating temperature is 0 to 50 degrees Celsius. Sensor Input Current Range MultiBrite was designed for use with EIT UVISENSORS. Current range through the sensor input terminals is 0.2 to 2.0 microamperes for a "100%" full scale reading. Display reading is adjustable by turning a respective channel's screw slotted "CALIBRATE" control located on the front panel. -

Page 21: Applications
® MultiBrite Operator's Manual APPLICATIONS The MultiBrite is capable of monitoring a curing system with up to four lamps. For curing systems with more than four UV sources, multiple MultiBrites can be cascaded. IMPORTANT The applications are shown using a model MB100AC1 (90 to 130 VAC input) for simplicity. Applications using a model MB240AC1 (180 to 264 VAC input) would use an appropriate transformer (with 24-volt output). -
