Warning Many electronic components located within the filter are sensitive to static electricity. Voltages
imperceptible to human touch can reduce the life, affect performance and/or destroy sensitive
electronic devices. Use proper electrostatic discharge (ESD) procedures when servicing the filter and
its circuit boards.
Troubleshooting Notes
• To reboot the system, remove power to the filter and Interface Module, wait a few minutes then
reapply. If this does not work check all the cable and connections, and try again. If the problem is
still not resolved replace the Interface Module assembly.
• If no buttons are pressed for 5 minutes the screen will turn off. To reactivate touch anywhere on the
screen.
• If the HMI Display shows a “COM 1 Station 1: Communication Error” across the bottom of the
screen check the serial cable between HMI Display COM1 and Interface PCB J1.
• If the HMI Display shows a “NO COM” indication on the system state indicator or a 7010
Communications Fault in the fault screen check the serial cable between Interface PCB J2 and the
HarmonicGuard Active filter power converter module J25 (100A/50A units) or J7 (200A units).
