due to a fault and the panel is configured with the optional automatic bypass
functionality. Note, included with the optional automatic bypass functionality
there is an intentional time delay inserted following a change from operating
from the inverter prior to bypass operation to allow time for the motor’s rotor
flux to decay.
Drive Fault Indicator
This optional orange light on the panel door indicates that the inverter is
reporting a fault condition. If your panel was ordered with the optional
automatic bypass functionality the panel will automatically switchover to
“Bypass” mode of operation following an inverter fault trip.
Motor Overload Indicator
This red light on the panel door indicates that the Class 20/30 motor overload
(OL) relay has tripped to protect the motor from damage due to excessive
current for an extended period of time. Actuation of the OL relay will
automatically cause power to be removed from the motor regardless of the
positions of the H-O-A and Drive/Off/Bypass selectors. The GE C-2000
TM OL
relay in your panel can be set for either manual or automatic reset. It is shipped
for manual reset, which means that the red button on the front of the OL relay
will have to be pressed to turn off the OL indicator and reapply power to the
motor. If desired that the motor restart automatically when the OL relay has
cooled down sufficiently, following an overload condition, then set the relay for
automatic reset. However, please note that the motor could restart at any time
without warning if the settings of the front panel selector switches still call for a
run condition.

CAUTION: Frequent activation of the motor overload relay may indicate
a problem with the ratings of your motor and/or drive panel components relative
to the nature of the driven load. Since an improper setting of the overload relay
could result in damage to the motor, please see the “Adjustments” section in
these instructions for details on the setting of the overload relay dial.
CAUTION: Please reference the instructions in the “Adjustments”
section of this manual regarding the setting of this time delay. An improper
setting could result in damage to your motor and/or driven equipment.
