Diagnostic Indicators

Drive LEDs:
Drive LEDs (green POWER and a red FAULT) are found on
the front of the drive. LEDs are visible through the panel
cover but not visible if a control panel is attached to the
drive.
Important: LEDs are found on the front of the drive,
under control panel/panel cover. If a control
panel is attached to the drive, switch to
remote control, otherwise a fault will be
generated. Remove the panel to view the
LEDs.
