Troubleshooting
The Baldor Series 15J Control requires very little maintenance, if any, and
should provide years of trouble free operation when installed and applied
correctly.
Occasional visual inspection and cleaning should be considered to ensure
tight wiring connections and to remove dust, dirt, or foreign debris which can
reduce heat dissipation.
Operational failures called faults are displayed on the keypad display as they
occur. A comprehensive list of these faults and their meaning is provided in
this section. The procedure to access the fault log and diagnostic information
is also provided.
Before consulting the factory, check that all power and control wiring is correct
and installed per the recommendations given in this manual.
