System Confi guration Options
The SA E-BUS Controller can be used as a Stand-Alone System (one
SA E-BUS Controller only), connected together on an Interconnected
System (multiple SA E-BUS Controllers only) or connected together
on a Network System (multiple SA E-BUS 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 E-BUS 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 SD
• Modular System Manager SD
• Personal Computer with Prism 2 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 E-BUS
Controller only. Programming and status monitoring are accomplished
by selecting and installing one or more of the Operator Interfaces.
See Figure 33 on page 57 for a Typical Stand-Alone System Layout
diagram.
Interconnected System
The Interconnected System is used when you have multiple SA E-BUS
Controllers on your job. With this system, you simply connect the con-
trollers together using WattMaster communications wire or 18-gauge,
2-conductor 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 58 for a Typical Interconnected System Layout
diagram.
Networked System
If you have 1 to 59 SA E-BUS Controllers that require information
sharing, simply connect the controllers together using WattMaster com-
munications 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
communications loop in a similar manner to the SA E-BUS Controllers.
The Networked Multiple Loop system is used when you have more
than 59 SA E-BUS Controllers and/or are using multiple SA E-BUS
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 communications 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 pro-
vides the capability for over 3500 controllers to be networked together.
See Figure 35 on page 59 for a Typical Networked System Layout
diagram.
