START-UP AND COMMISSIONING
Powering Up and Conguration
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 rst time, it
is very important to run through a few simple checks.
Power Wiring
One of the most important checks to make before powering up the
system for the rst time is to conrm proper voltage and transformer
sizing for each controller. Each VCCX2 Controller requires 15 VA
of power delivered to it at 24 VAC. Use separate transformers for
each device (preferred) or power several devices from a common
transformer.
WARNING: Observe polarity! All boards must be wired
with GND-to-GND and 24 VAC-to-24 VAC.
Failure to observe polarity will result in
damage to one or more of the boards.
Check all wiring leads at the terminal block for tightness. Be sure
that wire strands do not stick out and touch adjacent terminals.
Conrm all sensors required for the system are mounted in the
appropriate location and wired into the correct terminals on the
VCCX2 Controller.
After all the above wiring checks are complete, apply power to the
VCCX2 Controller.
Conguring the Controller
The next step is conguring the controller for specic requirements.
In order to congure the VCCX2 Controller, use an operator
interface. Four different operator interfaces are available for
programming and monitoring of the VCCX2 Controller. See Figure
13, this page. They are as follows:
• Modular Service Tool SD
• Modular System Manager SD
• PC with Prism 2 Software installed and CommLink 5
• System Manager TS-L (Touch Screen - Limited Access)
Any of these devices or a combination of them can be used to
access the status, conguration, and setpoints of any controller on
the communications loop.
NOTE: Use Prism II to configure units with RSMD-A,
RSMVHPQ and RSMZ modules.
If using the Modular Service Tool SD or the Modular System
Manager SD for programming, refer to the VCCX2 Controller
Operator Interface SD Technical Guide. If using a computer and the
Prism 2 software for programming, refer to the Prism 2 Technical
Guide.
If using the System Manager TS-L for monitoring, please see the
System Manager TS-L Technical Guide.
No matter which operator interface is used, AAON recommends
proceeding with the programming and setup of the VCCX2
Controller in the order that follows:
Congure the controller for the application.
1. Program the controller setpoints.
2. Program the controller operation schedules.
3. Set the controller current time and date.
4. Review the controller status screens to verify system
operation and correct controller conguration.
NOTE: For BACnet Conguration, see Appendix C.
