Troubleshooting

The Baldor Series 15H 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” will be displayed on the keypad display as they occur. A comprehensive list of these faults, their meaning and how to access the fault log and diagnostic information is provided later in this section. Troubleshooting information is provided in table format with corrective actions later in this section.

Before attempting to service this equipment, all input power must be removed from the control to avoid the possibility of electrical shock. The servicing of this equipment should be handled by a qualified electrical service technician experienced in the area of high power electronics.

It is important to familiarize yourself with the following information before attempting any troubleshooting or service of the control. Most troubleshooting can be performed using only a digital voltmeter having at least 1 meg Ohm input impedance. In some cases, an oscilloscope with 5 MHZ minimum bandwidth may be useful. Before contacting Baldor, check that all power and control wiring is correct and installed according to the recommendations in this manual.
