Diagnostics and
Troubleshooting
This chapter describes the equipment needed to check the operation of the Power
Module and the tests to be performed. Also included are descriptions of the Power
Module faults and warnings generated by the Distributed Power System Programming
Executive software. Procedures are provided for replacing fuses and sub-assemblies.
This chapter provides information to guide you in troubleshooting. The AutoMax
Distributed Power System employs extensive diagnostics to aid in correcting many
malfunctions that may occur in the system. This guide is designed to help you
interpret the diagnostic response of the Drive when a malfunction occurs. Possible
corrective measures will be explained to help you get the Drive repaired or functional
as quickly as possible for most types of malfunctions.
4.1 Recommended Test Equipment
!
ATTENTION:Only qualified electrical personnel familiar with the
construction and operation of this equipment and the hazards involved
should install, adjust, operate, or service this equipment. Read and
understand this manual and other applicable manuals in their entirety
before proceeding. Failure to observe this precaution could result in
severe bodily injury or loss of life.
ATTENTION:Hazard of electric shock exists in this Power Module.
Power circuit components are floating with respect to ground. Use only
approved methods of isolating test equipment when making
measurements in power circuits.
ATTENTION:Hazardous voltages may exist in the cabinet even with the
circuit breaker in the off position. Multiple sources of power may be
connected to this Power Module. Disconnect and lock out control
equipment from power sources, and discharge stored energy in
capacitors before coming into contact with any equipment in this cabinet.
ATTENTION:The Power Module contains ESD (Electro-Static
Discharge) sensitive devices. Static control precautions are required
when installing, testing, servicing or repairing this assembly. These
precautions should be applied when working with logic boards and any
components in the power section. A properly grounded wrist strap should
be worn when contacting any component in the Power Module.
!
ATTENTION:Potentially fatal voltages may result from improper use of
an oscilloscope and other test equipment. The oscilloscope chassis may
be at potentially fatal voltage if not properly grounded. Rockwell does
not recommend use of an oscilloscope to directly measure high voltages.
Use an isolated measuring device with a high voltage probe. Contact
Rockwell Automation for recommendations.
