Setting the EOL switch
Each field controller has an EOL (End of Line) switch, which, when set to ON (up), sets the field
controller as a terminating device on the bus. See Figure 3 for the EOL switch location on the field
controller. The default EOL switch position is OFF (down).
Figure 14: EOL switch positions
To set the EOL switch on a field controller:
1. Determine the physical location of the field controller on the N2 or FC Bus.
2. Determine if the field controller must be set as a terminating device on the bus.
Note:
Refer to the
N2 Communications Bus Technical Bulletin (LIT-636018)
for the N2
bus EOL termination rules. Refer to the
MS/TP Communications Bus Technical Bulletin
(LIT-12011034
) for the FC bus EOL termination rules.
3. If the field controller is a terminating device on the N2 or FC Bus, set the EOL switch to ON. If
the field controller is not a terminating device on the bus, set the EOL switch to OFF.
Note:
When the EOL switch is set to ON, the LED light on the face of the controller is
illuminated.
Commissioning
Use the following procedure to commission the FX-PCV18 controller:
1. Download the control application to the FX-PCV controller using the CCT. Refer to the Controller
Tool
Help (LIT-12011147)
.
2. Commission the VAV Box. Refer to the
Controller Tool Help (LIT-12011147)
.
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)
.
CCT connects to the FX-PCV through a laptop computer using any one of the following connection
options: the MAP Gateway, BTCVT, the Wireless ZigBee USB Dongle, or the wired BACnet
®
Ethernet
to MS/TP Router. These connection options require additional hardware listed in Table 8.
For more detailed N2 FX-PCV controller commissioning information, refer to the
N2 FX-PCV
Application Note (LIT-12011838).
Note:
• The MAP Gateway serves as a replacement for the BTCVT, which is no longer available for
purchase, but continues to be supported on select controllers.
• CCT 10.3 auto-detects when BTCVT can be used or not, based on the controller model and
the corresponding CCT Release mode.
