8.2.2 Drive Set for Manual Start and Reset *:
. In Manual Start Mode, the drive must
be manually restarted after a fault has cleared, using the optional Forward-Stop-
Reverse Switch. If a Short Circuit or I
2
t Fault occurs, the drive must be restarted
by setting either the On/Off AC Line Switch to the “OFF” position for a minimum of
5 seconds or setting the Forward-Stop-Reverse Switch to the “STOP” position.
*
Note: The optional Forward-Stop-Reverse Switch must be installed in order to
use the drive for Manual Start operation.
9 PILOT LIGHT AND DIAGNOSTIC LED’s
WARNING! DO NOT DEPEND ON THE PILOT LIGHT OR THE PC BOARD
MOUNTED LED’s FOR A GUARANTEED POWER OFF INDICATION. BE SURE ALL AC
POWER IS "OFF" BEFORE SERVICING THE DRIVE TO AVOID ELECTRICAL SHOCK
HAZARD.
9.1 PILOT
LIGHT:
The Pilot Light will illuminate orange when the AC line is applied to the
drive and the On/Off AC Line Switch is set to the “ON” position.
9.2 POWER ON LED (ON):
Located on the PC board, the “ON” LED will illuminate green
when the AC line is applied to the drive and the On/Off AC Line Switch is set to the “ON”
position.
9.3 STATUS
LED
(ST):
Located on the PC board, the “ST” LED is a green 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 and drive output
miswiring. It also provides a signal, which informs the user that all drive and
microcontroller operating parameters are normal. Table 11, summarizes the “ST” LED
functions.
9.4 OVERLOAD LED (OL):
The “OL” LED is a red LED, which provides indication of an
overload condition. Table 11, summarizes the “OL” LED functions.

LED will flash green and the “OL” LED will turn off. 3. In Manual Restart Mode, when the
Undervoltage or Overvoltage condition is cleared, the “ST” and “OL” LED’s will flash red / (red and
green) / green.
