Removing a terminal block
About this task:
To remove a terminal block from the circuit board,
complete the following steps:
Note: You need a flat blade screwdriver to remove
the terminal block.
1. To prevent any possibility of damage from an
accidental short, remove power from the
controller .
2. Underneath the terminal block, in the small gap
between the bottom of the terminal block and
the circuit board, insert the flat blade of the
screwdriver.
Figure 12: Terminal block
3. To detach the left-hand side of the terminal block,
position the flat blade underneath the terminal
block to the left, and push down the screwdriver
handle. When you do this, you are using the
screwdriver as a lever to pry up the terminal block.
4. To detach the right-hand side of the terminal block,
position the flat blade underneath the terminal
block to the right, and push down the screwdriver
handle.
5. If necessary, repeat steps 3 and 4 until the terminal
block is removed.
Setting the End-of-Line (EOL) switch
(CVM models only)
Each CVM controller has an EOL switch, which, when
set to ON (up), sets the CVM controller as a terminating
device on the bus. See Physical features for the EOL switch
location. The default EOL switch position is OFF (down).
Figure 13: End-of-Line Switch Positions
To set the EOL switch on a CVM controller, complete the
following steps:
1. Determine the physical location of the controller on
the FC Bus.
2. Determine if the controller must be set as a
terminating device on the bus.
Note: For detailed information about EOL
termination rules and EOL switch settings on
FC Buses, refer to the MSTP 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 illuminated.
Input and output wiring validation
The controllers ship with a cooling only, warm or cool
adjust application loaded by default. You can use this
default application to perform wiring verification using
the MAP Gateway or the DIS1710-0 local controller display.
To perform wiring validation, ensure that you set the
rotary switches to the desired address or controller
number and wire the input and output terminals. Apply
power to the controller. The Fault LED behaves the same
as it does during normal application load. When the Fault
LED turns off, connect to the device with either a MAP
Gateway or DIS1710-0 Local Display to view the points in
the controller.
Commissioning the controllers
To commission the controller, use the following
procedure:
1. With the desired application loaded in the controller,
commission the VAV Box. Refer to the Controller Tool
Help (LIT-12011147) .
2. Perform airflow balancing on the VAV box.
Refer to the VAV Balancing Tool Technical Bulletin
(LIT-12011087) .
3. Perform commissioning checkout procedures. Refer
to the Controller Tool Help (LIT-12011147) .
You commission equipment controllers with the CCT
software.
Commission controllers using the following connection
types.

1 Engines need to be at release 9.0 or later.
When the controller is configured to use the N2 protocol,
you must use the MAP Gateway at the SA Bus. Wireless
connections are not supported in N2 mode. These
connection options require additional hardware listed in
Table 12.
