System Confi guration Options
The SA Controller can be used as a Stand-Alone System (one SA Control-
ler only), connected together on an Interconnected System (multiple SA
Controllers only) or connected together on a Network System (multiple
SA Controllers, VAV/Zone Controllers, or Add-On Controllers) to form a
complete Orion Controls System that can be programmed and monitored
with one or more of the available Orion Operator 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 programming
and monitoring of SA Controller(s) and/or any VAV/Zone or Add-on
Controller(s) connected to your Orion System. The Operator Interfaces
available for use with the Orion Systems are as follows:
•
Modular Service Tool
• Modular System Manager
•
Personal Computer with Prism 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 SA Controller
only. Programming and status monitoring are accomplished by selecting
and installing one or more of the Operator Interfaces.
See Figure 33 on page 55 for a Typical Stand-Alone System Layout
diagram.
Interconnected System
The Interconnected System is used when you have multiple SA Control-
lers on your job. With this system, you simply connect the controllers
together using WattMaster communications wire or 18-gauge, 2-conduc-
tor twisted pair with shield wire (Belden #82760 or equivalent). This
allows for all controllers that are connected on the communications loop
to be programmed and monitored from one or more of the available
Operator Interfaces connected on the communications loop.
See Figure 34 on page 56 for a Typical Interconnected System Layout
diagram.
Networked System
If you have 1 to 59 SA 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 and/or CommLink
communication interface are purchased and wired into the communica-
tions loop in a similar manner to the SA Controllers.
The Networked Multiple Loop system is used when you have more
than 59 SA Controllers and/or are using multiple SA Controllers that
are connected to VAV/Zone controllers. These groups of controllers are
broken up into multiple “Local Loops” that connect to each other via
the “Network Loop.” Each individual MiniLink PD handles its specifi c
local loop’s communications requirements. The CommLink communica-
tions interface handles all the communications between the individual
MiniLink PDs to form the network loop. Up to 60 local loops can be
connected together with this confi guration. This provides the capability
for over 3500 controllers to be networked together.
See Figure 35 on page 57 for a Typical Networked System Layout
diagram.
