System Installation
Interconnected Systems
See Figure 4, page 23 for a detailed Interconnected System wir-
ing diagram. Also see pages 9-10 for wire and transformer sizing
information. You should review these diagrams before attempting
connections or powering up the controller or interface devices.
1. Connect all VCM-X E-BUS Controllers in a daisy chain
format using 18 gauge, 2 conductor shielded cable for
communications. Install a separate 24 VAC, 8 VA
minimum transformer for each VCM-X E-BUS
Controller and wire the transformers to each
controller using 18 gauge minimum, 2 conductor cable.
Observe polarity on all boards.
2. 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
Stand Alone.
3. The Modular System Manager SD comes supplied with
a 12 foot modular cable with a modular connector on
one end and stripped wires on the other. If the Modular
System Manager is to be mounted in a remote location,
run 18 gauge, 2 conductor shielded cable for
communications from the controller’s 3-wire
communications terminal to a junction box. Run 18
gauge minimum, 2-wire power wires from a separate
24 VAC, 6 VA minimum transformer into the junction
box. Splice the modular cable to the communications
and power wire inside of the junction box by making
solid connections, using wire nuts or butt splice
connectors. The Communications setting must be set
to Lo Speed Stand Alone. .
4. 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 <0> for the System Manager Address and make
sure One to One Unit Connection is not selected.
5. If a CommLink 5 is used to provide for connection to a
computer interface, connect communications using 18
gauge, 2 conductor shielded cable. Connect from one
of the controller’s 3-wire communications connectors
to the CommLink’s 3-wire communications connector.
For this type of system, the Loop switch on the back of
the CommLink needs to be set to “Single”.
6. Use 18 gauge minimum, 2-wire cable for all 24 VAC
power wiring. Be sure to maintain polarity on all boards.
If a CommLink 5 is installed, use the 110 VAC/24 VAC
power supply furnished with the CommLink for its
power source.
7. Before powering up the controllers, set each controller’s
board address to a unique number from 1 through 60.
Networked Single Loop Systems
See Figures 5-9, pages 24-28 for detailed Networked Single Loop
System wiring diagrams. Also see pages 9-10 for wire and trans-
former sizing information. You should review these diagrams before
attempting connections or powering up the controller or interface
devices.
Loop Containing VCM-X E-BUS Controllers Only
(Using CommLink 5)
1. Connect all VCM-X E-BUS Controllers on the loop in a
daisy chain format using 18 gauge, 2 conductor shielded
cable wiring from each controller’s communication
terminals to the next controller’s communication
terminals. Install a separate 24 VAC, 8 VA minimum
transformer for each controller and wire from controllers
to the transformers using 18 gauge minimum, 2 wire
cable. Be sure to observe polarity on all boards.
2. Connect 18 gauge minimum 2 conductor shielded cable
from one of the VCM-X E-BUS Controller’s 3 wire
communication terminals to the CommLink5’s 3 wire
communications terminal. The Loop switch on the
back of the CommLink must be set to “Single” for this
installation. Use the 110 VAC/24 VAC power supply
furnished with the CommLink for its power source.
3. 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.
4. The Modular System Manager SD comes supplied with
a 12 foot long modular cable with a modular connector
on one end and stripped wires on the other. If the System
Manager is to be mounted in a remote location, run 18
gauge, 2 conductor shielded cable for communications
from one of the controller’s 3 wire communications
terminals to a junction box. Run 18 gauge, 2 wire, 24
VAC power wires supplied by a separate transformer
into the junction box. Splice modular cable to the
communications and power wire inside of the junction
box using solid connections from wire nuts or butt-
splice connectors. The Modular System Manager MUST
always be connected on the “Local Loop”, never the
“Network Loop”. The Communications setting must be
set to Lo Speed Network Mode.
