. The number of the controller
can be written in the white squares provided so the
controller number can be more easily seen from a
distance.

numbers
Note:
The BACnet device ID is calculated
using the value of controller number added to
2000000. A device ID configured in this manner
does not require any configuration from CCT.
Input/Output Wiring Validation
The VMA1930 controllers ship with a default state
that can assist in validating the wiring of the input
and output terminals prior to download of an
application file. When the controller is powered on
in this state, the Fault LED will flash in a pattern of
two quick blinks and then a long pause (see Table
7).
To make use of this feature, ensure the rotary
switches are set to the desired controller number
and wire the input and output terminals. Apply
power to the VMA1930 controller and connect to the
device with either a MAP Gateway or MS-DIS1710-0
Local Display to view the points in the controller.
The VMA1930 controller will report an Operational
status even though there is no true application
loaded. CCT will not be able to commission or
upload the device as a result until a true application
is downloaded. The application name displayed will
be the controller number followed by the model of
the controller and “Default State”.
For example, a VMA1930 controller whose rotary
switches are set to 8 would have the default state
application name of
8-VMA1930 Default State
.
The default state creates I/O points for all
connections on the input and output terminals,
including the integrated DPT. It assumes all
Universal Inputs (UIs) are Nickel temperature
sensors. All Configurable Outputs (COs) are treated
as Binary Outputs (BOs) with an initial value of
0. The actuator on the VMA1930 will drive to the
50% setting. The default state also takes input
from a Network Sensor at address 199. If there is
no connected Network Sensor, the startup of this
default state will be delayed by 30 seconds as the
controller attempts to establish connection with the
sensor.
Commissioning Field Controllers
To commission the VMA1930 controller, use the
following procedure:
1. Download the control application to the
controller using the Controller Configuration
Tool (CCT). Refer to the
Controller Tool Help
(LIT-12011147)
and
Controller Provisioning with
Tools (LIT-12013247)
.
2. Commission the VAV Box.
3. Perform airflow balancing on the VAV box.
Refer to the
VAV Balancing Tool Technical Bulletin
(LIT-12011087)
.
4. Perform commissioning checkout procedures.
Refer to the
Controller Tool Help (LIT-12011147)
and
Controller Provisioning with Tools
(LIT-12013247)
.
You commission controllers with the CCT software.
The controller can be connected in one of four
ways; either through NxE Passthru, MAP 4.2+/
BACnet Router (Mobile Access Portal (MAP)
Gateway at version 4.2 or above), through Bluetooth
(using BTCVT), or Direct Ethernet connection to
the controller. Refer to the
Controller Tool Help
(LIT-12011147)
and
Controller Provisioning with
Tools (LIT-12013247)
for detailed information about
commissioning field controllers.
Note:
• The Bluetooth connection can be used
to Transfer to Computer (Upload) and
commission the controller, but cannot be
used to Transfer to Device (Download).
