Important:
Disconnect all power sources to
the expansion module before removing the
cover and changing the position of any jumper
or the EOL switch on the expansion module.
Failure to disconnect power before changing
a jumper or EOL switch position can result in
damage to the expansion module and void any
warranties.
The expansion module cover is held in place by
four plastic latches that extend from the base
and snap into slots on the inside of the housing
cover.
To remove the expansion module cover,
complete the following steps:
1. Place your fingernails under the two cover
lift tabs (Figure 1) on the sides of the housing
cover and gently pry the top of the cover away
from the base to release the cover from the two
upper latches.
2. Pivot the top of the cover further to release it
from the lower two latches.
3. Replace the cover by placing it squarely over
the base, and then gently and evenly push the
cover onto the latches until they snap into the
latched position.
Setting the End-of-Line (EOL) switch
Each controller has an EOL switch, which, when set
to ON, sets the controller as a terminating device on
the bus. The default EOL switch position is OFF.
Figure 9: End-of-Line switch positions
To set the EOL switch on a field controller, complete
the following steps:
1. Determine the physical location of the field
controller on the FC bus.
2. Determine if the controller must be set as a
terminating device on the bus.
Note:
For detailed information regarding EOL
termination rules and EOL switch settings on
FC buses, refer to the
MS/TP Communications
Bus Technical Bulletin (LIT-12011034)
.
3. If the controller is a terminating device on
the FC bus, set the EOL switch to ON. If the
controller is not a terminating device on the
bus, set the EOL switch to Off.
When a controller is connected to power with its
EOL switch set to ON, the amber EOL LED on the
controller cover is lit.
Commissioning the Controllers
Commission BACnet MS/TP field controllers with the
controller (CCT) software, either via a Bluetooth
®
Wireless Commissioning Converter, a ZFR wireless
adapter
(BACnet MS/TP only)
, or in BACnet routing
mode when connected to an NAE or NCE.
Note:
N2-capable controllers do not support
Zone Bus or XT Bus. They do not support
wireless connections to the N2 Bus.
Refer to the
Controller Tool Help (LIT-12011147)
for detailed information on commissioning field
controllers.
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
Observe the Status LEDs on the front of the
expansion module. Table 7 provides LED status
indicator information for troubleshooting the
expansion module.
