13 – DIAGNOSTIC LEDs
The drive contains two diagnostic LEDs mounted on the enclosure cover to display the drive's operational status.
WARNING! Do not depend on the PWR LED as a guaranteed power off condition. Be sure the main power switch or circuit breaker is in
the "OFF" position before servicing this drive.
13.1 – POWER ON LED (PWR)
The "PWR" LED will illuminate green when the AC Line is applied to the drive.
13.2 – STATUS LED (ST)
The "ST LED 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 6 summarizes the "ST" LED
functions.
14 – OPTIONAL ACCESSORIES
Detailed instructions are provided with all accessories. See Table 7.
