This SERVICE MANUAL provides technical assistance to Welch

Allyn repair technicians for diagnosing, repairing, and testing the WELCH ALLYN LS100 HALOGEN LIGHT. The manual's main content areas cover: troubleshooting, step by step repair, adjustment, and re-test procedures. The repair 'TASK' procedures (R & R .. Removal and Replacement) are written to provide quick and easy reference for repair technicians of different experience levels. Required specifications and materials are listed at each step where applicable. When reading this manual for the first time, have an LS100 readily available for reference and practice. Read each complete repair step on what to do (task statement), plus how to do it (technique statement) before starting the repair or practice.

Training for the LS100 should consist of detailed demonstrations of required repair tasks, practice on LS100'S using repair tooling and materials. Assess skill development through observation of trainee practice on actual equipment. Set up sessions to allow the trainee to practice the use of the diagnostic, repair, adjustment, and re-testing procedures found in this manual. The ability of the technician to develop and retain new skills is in great part dependent on well prepared training exercises. Each trainee must have the opportunity to practice the procedure(s) after it has been demonstrated by the instructor. More detailed background product information is found in the APPENDIX section and as such will be a critical element in a comprehensive service training program for technicians.

PRODUCT DESCRIPTION LS100

The LS100 Halogen Light is a non-stationary floor standing light. It is used for routine medical examinations and as such has a flexible 'gooseneck' which facilitates whole-body examination. The light housing is manufactured of injection molded plastic which minimizes surface temperature. The power source for the LS100 is standard A.C. for the country it is sold into. Different source voltages and frequencies are accommodated by manufacturing the LS100 with either of two basic transformers, and the appropriate plug configuration. These are the only differences between the six different model numbers of the LS100. The secondary, or lamp voltage is 12 v.a.c.. All models use the same 20 watt halogen lamp PN06300. Lamp current is switched by Single Pole Single Throw (spst) switch. The transformer however, is energized as long as the power plug is connected to a power source.

Please refer to the Owner's Manual WA pn440001-1 for information on "Set-Up and operation".

This product is designed and manufactured to strict specifications and safety regulations for medical products, and should be serviced only by Welch Allyn trained technicians.
