Enable Indicator
This clear light on the panel door indicates that the customer interlock circuit is
closed and the system is ready for the motor to be energized. Note, with the
customer safety interlock circuit open the panel will not allow output power to
the motor in either “Bypass” or “Drive”.
Motor Overload Indicator
This red light on the panel door indicates that the Class 20/30 motor overload
(OL) relay has actuated 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.
Bypass Run Indicator
This blue light on the panel door indicates that the bypass contactor is
energized and therefore that 50 or 60 cycle AC line power is being applied to
the motor. In order for this to happen the Drive/Off/Bypass selector must be in
the “Bypass” position and the H-O-A switch must be in either the “Hand” or
“Auto” positions (if “Auto” then remote run contacts must also be closed). Note
that bypass operation can also occur in “Drive” mode if the drive has tripped
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 Run Indicator
This optional green light on the panel door indicates that the drive output
contactor is energized and the drive will output power to the motor. The
conditions that will cause this light to become energized are; Drive/Off/Bypass
and Test/Isolate/Normal switches are in the “Drive” and “Normal” positions

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.
