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 VCM-X E-BUS Controllers are equipped with address switches. If
the VCM-X E-BUS Controller is to operate as a stand-alone system (not
connected to any other HVAC unit or VAV/Zone Controllers), the control-
ler address switch should be set for address 1. When using the Modular
Service Tool or System Manager to program and confi gure the VCM-X
E-BUS Controller, 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 VCM-X
E-BUS Controller will be used with VAV/Zone Controllers, the VCM-X
E-BUS Controller’s address switch must be set as address 59, no excep-
tions. See Figure 41 below for address switch setting information. For
detailed information regarding communication wiring and connection
for interconnected and networked systems, please see the Orion Systems
Technical Guide—OR-SYS-TGD-XX.
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 VCM-X E-BUS Controller requires 8
VA of power delivered to it at 24 VAC. Each VCM-X Expansion Mod-
ule requires 10 VA at 24 VAC and each 12-Relay Expansion Module
requires 15 VA at 24 VAC. 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
