14.1 ILLUMINATED ON/OFF AC LINE SWITCH
The On/Off AC Line Switch will illuminate when the AC line is applied to the drive and
the switch is in the ON ("I") position.
14.2 POWER ON LED (PWR)
The "PWR" LED, located on the drive's PC board, will illuminate green when the AC
line is applied to the drive and the On/Off AC Line Switch is set to the on ("I") position.
14.3 STATUS LED (ST)
The "ST" LED, located on the drive's PC board, is a tricolor LED which provides
indication of a fault or abnormal condition. The information provided can be used to
diagnose an installation problem such as incorrect input voltage, overload condition,
and drive output miswiring. It also provides a signal which informs the user that all
drive and microcontroller operating parameters are normal. Table 7, summarizes the
"ST" LED functions.
