Addressing & Powering Up
Before Applying Power
In order to have a trouble free start-up, it is important to follow a few
simple procedures. Before applying power for the fi rst time, it is very
important to correctly address the controller and run through a few
simple checks.
Controller Addressing
All SA E-BUS Controllers are equipped with address switches. If the SA
E-BUS Controller is to operate as a stand-alone system (not connected to
any other HVAC unit or VAV/Zone Controllers), the controller address
switch should be set for address 1. When using the Modular Service Tool
or System Manager to program and confi gure the SA E-BUS Control-
ler, you would enter this address to communicate with the controller.
When the system is to be connected to other HVAC unit controllers on
a communication loop, each controller’s address switch must be set with
a unique address between 1 and 59. When the SA E-BUS Controller
will be used with VAV/Zone Controllers, the SA E-BUS Controller’s
address switch must be set as address 59, no exceptions. See Figure 29
below for address switch setting information.
Power Wiring
One of the most important checks to make before powering up the
system for the fi rst time is to confi rm proper voltage and transformer
sizing for each controller. Each SA E-BUS Controller requires 8 VA of
power delivered to it at 24 VAC and each of the modules require differ-
ent VA loads (see Table 1 on page 10 for details). You may use separate
transformers for each device (preferred) or power several devices from a
common transformer. If several devices are to be powered from a single
transformer, correct polarity must be followed.

Note:
The Power To The Controller Must Be Removed And
Reconnected After Changing The Address Switch Settings In
Order For Any Changes To Take Effect.
Caution:
Disconnect All Communication Loop Wiring From The
Controller Before Removing Power From The Controller.
Reconnect Power And Then Reconnect Communication Loop
