• U-Line Zone GFBs
If you have InterOp Tools version 3.0, you
must install Eikon 3.0a or the InterOp Tools
Service Pack 1. There is no cost for Eikon
3.0a.
Start-Up Checklist
1. Use the appropriate version of Eikon for
WebCTRL or Eikon 3.0a or later to create
GFBs for U-Line modules. Be sure to
enable the Zone GFB option in Eikon for
WebCTRL or Eikon. Refer to "Writing GFBs
for the U551" on page 9 for more
information.
2. Use the appropriate module driver. (See
"Job Start-Up" on page 3.)
3. Connect the U-Line modules to the Unet
and the UNI.
4. Transfer the U-Line modules' GFBs to the
UNI.
Mounting
Screw the U551 into an enclosed panel using
the mounting holes provided on the cover
plate. Be sure to leave about 2 inches (5
centimeters) on each side for wiring.
Addressing
The U551 has dual rotary switches for
assigning the board address. The top switch
corresponds to the tens digit and the bottom
switch corresponds to the ones digit (see
Figure 2). The U551's address must be the
same as its FB number in the UNI.
For example, if the module's FB number is
nine, set the tens switch to zero and the ones
switch to nine.

Revised 8/14/02 • U551
The U551's BACnet Device Instance number
can be assigned by the UNI or individually
specified. This number is shown on the UNI
Properties page in WebCTRL or on the UNI
Status page in SuperVision.
Power Wiring
The Unet follows the same specifications as a
legacy CMnet. Refer to the Technical
Handbook for details on legacy CMnets. Also
refer to the Technical Handbook for detailed
information on daisy-chain, star, and hybrid
wiring configurations.
There is a special wire available that contains
a pair of 14AWG wires for power and a pair of
22AWG wires for communication. This wire is
available from:
Magnum Cable Corporation
Cleveland, OH 44110-0500
(800) 421-0820
Product number A3U-LINE
CAUTION The U551 modules are Class 2
devices (less than 30VAC, 100VA maximum).
Take appropriate isolation measures when
mounting a U551 module in a control panel
where Non-Class 2 devices (120V and
greater) or wiring are present.
You can power several modules from the
same transformer by daisy-chaining the
power from one U-Line module to the next.
You must maintain the same polarity.
Do not exceed 100VA or 500 feet (152.4
meters) total of 14AWG wire. The maximum
number of modules on one transformer can
be figured by dividing the VA of the
transformer by the sum of the VA of the
module plus the VA of any accessories. For
example, if the module's power is 9VA,
accessories per module equal 6VA, and the
transformer is 100VA, you could have up to 6
modules on the network. See the formula in
Figure 3 and the example in Figure 4.
