VCM-X Component & Systems Wiring 13
System Installation
5. 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
6 VA minimum power and should be connected using
18 gauge minimum, 2 conductor wire. In the Settings
Menu, enter <63> for the System Manager Address.
6. Before powering up the controllers, set each controller’s
board address to a unique number from 1 through 59.
Loop Containing VCM-X E-BUS Controller with Modular
VAV/Zone Controllers and MiniLink PD Only
1. Connect all controllers in a daisy chain format
using 18 gauge, 2 conductor shielded cable for
communications. 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. Using 18 gauge minimum, 2 wire cable
for power, install a separate 24 VAC transformer sized
for the required VA load for each Power/Comm board on
the loop and wire from each transformer to its Power/
Comm board. Observe polarity on all boards.
2. Connect 2 conductor shielded cable 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, 2 wire
cable for all power wiring and be sure to maintain
polarity on all boards.
3. Using a modular cable, connect from the MiniLink PD’s
modular connector marked “Local Loop” to a
Power/Comm board’s modular input connector.
4. Using modular cables, connect from the Power/Comm
board’s modular output connectors to the Modular 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.
5. 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.
6. The Modular System Manager SD can connect to any
VAV/Zone Controller or directly to one of the Power/
Comm board’s modular output connectors. 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. In the Settings Menu, enter <63> for the
System Manager Address.
8. 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 at 1.
Note: Only communications, not power, are transferred
from the MiniLink Polling Device to the Power/
Comm board via the modular cable. A separate
transformer is required for the MiniLink Polling
Device. 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
connected to the Power/Comm board. The
transformer should be sized for the required
VA by using the information found on pages
9-10 of this manual.
