System Installation
5. Repeat the above steps for each local loop containing
VCM-X E-BUS Controllers with VAV/Zone Controllers.
6. The Modular System Manager can connect to any
VAV/Zone Controller on the entire system or directly
to one of the Power/Comm board’s modular output
connectors using modular cable. The Modular Service
Tool will connect to any of the controllers using the
supplied cable with DIN connectors on both ends. The
connection point on the controllers is located near the
communications connector. The Communications setting
must be set to Lo Speed Network Mode.
7. The System Manager TS II utilizes a 3 wire
communication terminal block for connection to
any controller on the communications local loop that
has communication wire terminals. Since you are using
Modular VAV/Zone Controllers, you can use a modular
pigtail connector that has a modular connector on
one end and stripped wires on the other to connect the
System Manager TS II to the Power/Comm board or one
of the Modular VAV/Zone Controllers. A separate
transformer is required for the System Manager TS II.
It has a 2 wire 24 VAC terminal block for connection to
a 24 VAC transformer. The transformer should be sized
to provide 6 VA minimum power and should be
connected using 18 gauge minimum wire.
8. The Modular Service Tool SD will connect to any
of the controllers using the supplied cable with DIN
connectors on both ends. The connection point on the
controller is located near the communications connector.
The Communications setting must be set to Lo Speed
Network Mode.
9. Using 2 conductor shielded cable, connect from the
CommLink 5’s 3 wire communications connector to one
of the MiniLink PD’s 3 wire communications connector
marked “Network Loop”. The Loop switch on the back
of the CommLink 5 must be set to “Multiple”. The
CommLink 5 only needs to be connected to one of the
MiniLink PDs on the system.
10. Using a modular cable, connect from each MiniLink
PD’s modular connector marked “Network Loop” to
the next MiniLink PD’s “Network Loop” modular input
connector using modular cable. Connect all the
remaining MiniLink PD’s in the same manner using a
daisy chain format.
11. Before powering up the controllers, set each VAV/
Zone Controller’s board address to a unique number
from 1 through 58. Address the VCM-X E-BUS
Controller at 59. Set MiniLink PD’s address from 1 to
60.
Note: Both power and communications are transferred
from the Power/Comm board to the VAV/Zone
Controllers and the Modular System Manager.
Warning: Each Power/Comm board must have its own
24 VAC transformer for its power source. This
transformer cannot be shared with any other
board. Do not ground the transformer that is con-
nected to the Power/Comm board. The transform-
er should be sized for the required VA by using
the information found on pages 9-10 of this
manual.
Local Loops containing VCM-X E-BUS Controllers with
Non-Modular VAV/Zone Controllers
1. Using 18 gauge minimum, 2 wire cable for power, install
a 24 VAC, 8 VA minimum, transformer for the VCM-X
E-BUS Controller and wire from the transformer to the
VCM-X E-BUS Controller.
2. Using 2 conductor shielded cable, connect from the
VCM-X E-BUS Controller’s 3 wire communications
connector to the MiniLink PD’s 3 wire communications
connector marked “Local Loop”. Use 18 gauge
minimum wire for power and observe polarity on
all boards.
3. Using 2 conductor shielded cable, connect from the
VCM-X E-BUS Controller’s 3 wire communications
connector to the VAV/Zone Controllers. The VAV/Zone
Controllers connect together using modular cables from
each VAV/Zone Controller to the next controller and/or
to a Power/Comm Board. A maximum of 16 VAV/Zone
controllers are allowed per Power/Comm board. If you
have more than 16 VAV/Zone controllers, you will need
multiple Power/Comm boards. Each Power/Comm
board must have its own 24 VAC transformer sized for
the total number of VAV/Zone controllers connected to
it.
4. Repeat the above steps for each local loop containing
VCM-X E-BUS Controllers with VAV/Zone Controllers.
5. The Modular System Manager can connect to any
VAV/Zone Controller on the entire system or directly
to one of the Power/Comm board’s modular output
connectors using modular cable. The Modular Service
Tool will connect to any of the controllers using the
supplied cable with DIN connectors on both ends. The
connection point on the controllers is located near the
communications connector. The Communications setting
must be set to Lo Speed Network Mode.
6. The System Manager TS II utilizes a 3 wire
communication terminal block for connection to any
controller on the communications local loop that has
communication wire terminals. A separate transformer
is required for the System Manager TS II. It has a 2
wire 24 VAC terminal block for connection to a 24 VAC
transformer. The transformer should be sized to provide
Networked Multiple Loop
