Troubleshooting
Introduction The purpose of this chapter is to assist in troubleshooting the ArmorStart®
Distributed Motor Controller using the LED status display and diagnostic
parameters.
ATTENTION: Servicing energized industrial control equipment can be hazardous.
Electrical shock, burns or unintentional actuation of controlled industrial equipment
may cause death or serious injury. For safety of maintenance personnel as well as others
who might be exposed to electrical hazards associated with maintenance activities,
follow the local safety related work practices (for example, the NFPA70E, Part II in the
United States). Maintenance personnel must be trained in the safety practices,
procedures, and requirements that pertain to their respective job assignments.
ATTENTION: Do not attempt to defeat or override fault circuits. The cause of the fault
indication must be determined and corrected before attempting operation. Failure to
correct a control system of mechanical malfunction may result in personal injury and /
or equipment damage due to uncontrolled machine system operation.
ATTENTION: The drive contains high voltage capacitors that take time to discharge
after removal of mains supply. Before working on drive, ensure isolation of mains
supply from line inputs (R, S, T, [L1, L2, L3]). Wait three minutes for capacitors to
discharge to safe voltage levels. Failure to do so may result in personal injury or death.
Darkened display LEDs is not an indication that capacitors have discharged to safe
voltage levels.
ATTENTION: Only qualified personnel familiar with adjustable frequency AC drives and
associated machinery should plan or implement the installation, startup, and
subsequent maintenance of the system. Failure to comply may result in personal injury
and/or equipment damage.
ATTENTION: This drive contains electrostatic discharge (ESD) – sensitive parts and
assemblies. Static control precautions are required when installing, testing, servicing,
or repairing this assembly. Component damage may result if ESD control procedures
are not followed. If you are not familiar with static control procedures, refer
to Allen-Bradley Publication
8000-4.5.2 , Guarding against Electrostatic Damage,
or any other applicable ESD protection handbook.
