REPAIRS & SERVICE
5.1
ATS SERIES FIELD REPAIR (RECOMMENDED REPLACEMENT PARTS)
The ATS Series is designed to facilitate quick replacement of circuit boards in the field.
Therefore, troubleshooting procedures described in this manual are limited to visual
inspection and circuit board replacement only. Actual component-level
troubleshooting, repair and calibration require the completion of a full training course
at TSi Power. For most customers, the most cost-effective way to repair it is to simply
replace the board assembly. Spare parts can be ordered from TSi Power directly. The
Replacement Parts Table below provides correct part numbers and descriptive
information. Please contact TSi Power prior to ordering so that the correct parts for each
particular version of the ATS-500 Series will be available.
