System Configuration Options
The VCM controller can be used as a Stand Alone System (One VCM
Controller Only), connected together on a Interconnected System (Mul-
tiple VCM controllers Only), or connected together on a Network Sys-
tem (Multiple VCM Controllers, VAV/Zone Controllers, or Add -on
Controllers) to form a complete Orion Controls System that can be pro-
grammed and monitored with one or more of the available Orion Op-
erator Interfaces.
For detailed information about the various Orion Controls Systems that
are available and their related wiring requirements and options, please
see the Orion Systems Technical Guide.
Operator Interfaces
The Orion Operator Interfaces are designed to provide for program-
ming and monitoring of VCM controller(s) and/or any VAV/Zone or
Add-on Controller(s) connected to your Orion System. The Operators
Interfaces available for use with the Orion Systems are:
• Modular Service Tool
• Modular System Manager
•
Tactio SI - Touch Screen Interface
• Personal Computer with Prism II Computer Front End
Software Installed
You can use any one of these interfaces or all of them on the same Orion
System.
Stand Alone System
The Stand Alone system is used when you have a single VCM control-
ler only. Programming and status monitoring are accomplished by se-
lecting and installing one or more of the Operator Interfaces.
See Figure 32 for a Typical Stand Alone System Layout diagram.
Interconnected System
The Interconnected system is used when you have multiple VCM con-
trollers on your job. With this system you simply connect the control-
lers together using WattMaster communications wire or 18 gauge 2
conductor twisted pair with shield wire (Belden #82760 or equiva-
lent). This allows for all controllers that are connected on the commu-
nications loop to be programmed and monitored from one or more of
the available Operator Interfaces connected on the communications
loop.
See Figure 33 for a Typical Interconnected System Layout diagram.
Networked System
If you have 1 to 59 VCM controllers that require information sharing ,
simply connect the controllers together using WattMaster communica-
tions wire or 18 gauge 2 conductor twisted pair with shield wire (Belden
#82760 or equivalent). The Networked Single Loop system requires
that either a MiniLink PD communication interface or a CommLink
communication interface or both are purchased and wired into the com-
munications loop in a similar manner to the VCM controllers.
The Networked Multiple Loop system is used when you have more
than 59 VCM controllers and/or are using multiple VCM controllers
that are connected to VAV/Zone controllers. These groups of control-
lers are broken up into multiple “Local Loops” which connect to each
other via the “Network Loop”. Each individual MiniLink PD handles
its specific local loop’s communications requirements. The CommLink
communications interface handles all the communications between the
individual MiniLink PDs to form the network loop. Up to 60 local loops
can connected together with this configuration. This provides the capa-
bility for over 3500 controllers to be networked together.
See Figure 34 for a Typical Networked System Layout diagram.
