Product Description
The Advantage Central Monitoring
Unit is a communications center which
transmits to and receives data from up
to 99 Advantage starters or contactors
or IQ500s equipped with PONI cards.
The CMU can be mounted on the door
of a motor control center or custom
panel using the existing IQ cutout
dimensions.
The eight-digit alphanumeric display
monitors active data, trip data or set
points. The group of data being dis-
played is indicated by one of three
LEDs and is selected by the user. The
two-digit alphanumeric display indi-
cates the address of the device about
which the data is being displayed. This
address is also selected by the user.
Five LEDs are provided which indicate
the present status of the selected
starter. Two additional LEDs are also
provided at the top of the panel, one
which indicates that the CMU is
OPERATIONAL, and another which
indicates ALARM status. An
ACKNOWLEDGE/RESET button
permits the user to reset the CMU
following a device trip.
The CMU can be interfaced into a
larger PowerNet network with the
addition of a PowerNet PONI
Communications Module.
