• The MAP Gateway serves as a replacement
for the BTCVT, which is no longer available
for purchase, but continues to be supported.
Firmware Package File
The MS-FCP-0 equipment controller firmware
package files are required for CCT to configure and
commission the controllers. The firmware package
files also allow you to upgrade an existing controller
to the latest firmware release available for that
controller.
Beginning at CCT Release 13, the firmware package
files are orderable separately; they are not included
with CCT. They are obtained from the Metasys
software licensing portal, and are loaded and
licensed on the computer/server that is running
CCT.
For additional information about the firmware
package files, refer to the CCT Installation Instructions
(LIT-12011259) .
Troubleshooting Field Controllers
Observe the Status LEDs on the front of the
expansion module. Table 7 provides LED status
indicator information for troubleshooting the
expansion module.
General troubleshooting provides some additional
troubleshooting information for possible problems.
Note: If you experience short circuits in the 24
VAC power supply causing protective devices
such as breakers or fuses to trip, make sure
that the power connections on theVMA1930 are
not reversed. The most common cause of this
problem is when the 24 VAC power supply on
the VMA1930 is reversed but not reversed on a
connected secondary device. Improper wiring
of this power terminal may cause a short circuit
across the 24 VAC power supply.
LED status and states
Table 7: Status LEDs and description of LED states
LED label LED color Normal state Descriptions of LED states
POWER Green On Steady
Off Steady = No power
On Steady = Power is supplied by primary voltage
FAULT Red Off Steady
2 blinks followed by long pause = Controller powered
on in default state. For more information about this
default state, see Input/Output Wiring Validation .
Blink - 2 Hz = Download or startup in progress, not
ready for normal operation, SA Bus devices offline
(such as netsensors)
Rapid blink = SA Bus communications issue
Off Steady = No faults
On Steady = Device fault or no application loaded
SA BUS Green Blink - 2 Hz
Blink - 2 Hz = Data transmission (normal
communication)
Off Steady = No data transmission (N/A - auto baud
not supported)
On Steady = Communication lost; waiting to join
communication ring
ETH1 Green Off
Off Steady = ETH1 is not connected
Blinking = ETH1 connected and communicating
ETH2 Green Off
Off Steady = ETH2 is not connected
Blinking = ETH2 connected and communicating
