DESCRIPTION
The Model 455 three-phase voltage monitor combines load
and line-side monitoring to alert the user of contact failure or
impending contact failure. The line-side monitoring will protect
the motor from damaging line-side conditions prior to the motor
starting. With the Model 455, your motor is fully protected at all
times. The motor will not start if a power problem is present.
The monitor is equipped with an infrared LED to communicate
with the handheld diagnostic tool, the Informer-MS, to display
MotorSaver
®
data to assist in monitoring and troubleshooting the
system. Motor run hours, displayed by the Informer-MS can now
be reset on the Model 455.
