System Installation
Stand-Alone
MiniLink Polling Device (MiniLink PD)
Standard Connection Confi gurations and Use
The MiniLink PD is used on Networked Single and Multiple Loop
systems to provide two-way communication between all devices on
it’s “Local Loop” and to all the other “Network Loop” devices on
the entire system. The MiniLink PD is equipped with both modular
connectors and hard wiring terminal blocks for connection of 24
VAC power “Local Loop” and “Network Loop” communications.
Each MiniLink PD is normally hard wired to a 24 VAC power
source connected to its 24 VAC input terminal (TB1). “Network
Loop” communications are transferred between multiple MiniLink
PDs by modular cables connected to their “Network Loop” modu-
lar connectors (P3 and P5). A CommLink 5 must be connected to
one of the MiniLink PDs on the system by using a 2-wire shielded
cable connected between its 3-wire “Network Loop” communica-
tions terminal block (TB4) and to the CommLink’s “485 Loop”
terminal block. Transfer of “Local Loop” communication from the
MiniLink PD to a Power/Comm board is made by using a modular
cable connected between the MiniLink PD “Local Loop” modular
connector (P4) and the Power/Comm board modular “Comm In”
connector (P2). If desired as an alternative, transfer of “Local Loop”
communication from the MiniLink PD to a Power/Comm board can
be made by hard wiring a 2-wire shielded cable connected between
the MiniLink PD’s 3-wire communications terminal (TB1) and the
3-wire communications input (TB1) on the Power/Comm board.
Installation Procedures
The installation procedures that follow are based on recommended
methods of wiring connection and controller installation. Installation
procedures vary depending on the type of system you are installing.
The system you are installing could be a Stand Alone, Interconnected,
Networked Single Loop, or Networked Multiple Loop system. The
Networked System also has installation variations based on the type
of components you are installing for that system. The following
information explains the procedures for all of these systems. Please
fi nd the system and components that closely match your system and
follow the outlined procedures.
Stand Alone Systems
See Figure 3, page 22 of this manual for a detailed Stand Alone
System wiring diagram. Also see pages 9-10 for wire and transformer
sizing information. You should review these diagrams before attempt-
ing connections or powering up the controller or interface devices.
1. Install a 24 VAC, 8 VA minimum, transformer for the
VCM-X E-BUS Controller and wire from transformer
to the controller using 18 gauge minimum, 2 conductor
cable for power. Observe polarity on all power wiring.
2. The Modular Service Tool SD connects to 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 Comm-
unications 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
using 18 gauge minimum 2 conductor wire. In the
Settings Menu, enter <0> for the System Manager
Address.
5. If a CommLink 5 is used for a computer interface,
connect communications using 18 gauge, 2 conductor
with shield cable. Connect from the controller’s 3-wire
communications connector to the CommLink’s 3-wire
communications connector. For this type of system, the
Loop switch located on the back of the CommLink 5
must 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 is connected, use the 110 VAC/24 VAC
power supply furnished with the CommLink for its
power source.
7. Before powering up the controller, set the desired board
address on the controller (usually 1).
