Troubleshooting
MN715P Troubleshooting 5-1
The Baldor Series 15P Control requires very little maintenance, if any, and
should provide years of trouble free operation when installed and applied
correctly. Occasional visual inspection to ensure tight wiring connections
and cleaning to remove dust, dirt, or foreign debris which can reduce heat
dissipation should be considered.
Operational failures called faults are displayed on the LED’s as they occur.
Procedures in this section describe how to recognize a fault and restore
normal operation.
Before service is performed, all input power must be removed from the
control to avoid electrical shock hazard. Most troubleshooting can be
performed using only a digital voltmeter having an input impedance
exceeding 1 megohm. In some cases, an oscilloscope with 5 MHz minimum
bandwidth may be useful. Before consulting the factory, check that all power
and control wiring is correct and installed per the recommendations given in
this manual.

Fault Code Determination
The Fault LED may blink to indicate a fault code (1 through 5). A fault code
sequence is displayed as follows:
Fault LED OFF = 1.5 second and then blink “X” number of times (2 times per
second). “X” is the fault code 1 to 5. After you determine the fault code,
refer to Fault Code Descriptions for a description of the fault.
