TROUBLESHOOTING
WARNING
Do not remove the cover of the inverter when the power is ON to avoid injury caused by electrical shock.
This control does not require maintenance under normal conditions. If you encounter a problem, read all instructions provided with this control and double- check the wiring. If problems persist, contact your source of purchase or a Bodine Authorized Service Center and describe the problem in detail. Performing unauthorized repairs will void the Warranty.
GENERAL EVALUATION – Knowing the circumstances under which the problem occurred can help to identify the root cause of the problem.
Has the system ever operated properly? If the control was just installed and doesn’t work right, then it is likely that something wasn’t done correctly in the installation. However, if the system has been working for an extended period of time and just recently stopped working, then this would indicate that the control was initially installed properly but something has somehow changed.
Is the problem continuous or intermittent? If the problem always occurs and never goes away, then it would indicate something inherently wrong in the connections or a defective component. On the other hand, if the system operates properly most of the time and only occasionally does something wrong, then this might indicate loose connections or electrical noise interference.
