Compressor status is ASCII-coded. In order to obtain the
status from BACnet, statuses are assigned a BACnet code as
shown in Table A.
Table A — Equipment Status
Alarm states are coded as shown in Table B.
Table B — Alarm States
Modifying the Unit IP Address —
Note that chang-
ing IP address from the PIC 5 SETUP menu will require a
manual reboot or power cycle of the PIC 5 controller in order
to re-build the BACnet stack. For detailed instructions, see the
Unit IP Address section on page 49.
BACnet IP Communication Problems —
If the
unit does not respond to the building management system, pos-
sible causes include the following:
• The BACnet dongle is not detected by the chiller application.
• The Ethernet cable is not correctly connected.
• Network parameters are not correct (see the Ethernet/IP
Connection Problems section on page 53).
• There is an IP router between the equipment and the
building management system.
• BACnet Enable parameter in the PIC 5 Configuration
Menu is set to No.
To troubleshoot problems, try these measures:
• Open the metal casing of the 19XR PIC 5 controller and
verify that the blue BACnet dongle is correctly connected.
• On the Ethernet connector, verify that the green LED is
ON and the orange LED is blinking.
• Use the Windows ping utility to ping the IP address of
the controller.
• Open 19XR PIC 5 Configuration Menu (Service pass-
word required) and check BACnet parameters.
• Use the free software called BDT (BACnet Discovery Tool)
available on the internet (search
bacnet bdt
) and install it on
the PC. All equipment connected to the BACnet network
will respond to the “Who Is” command sent by this tool.
Find the equipment configured with the BACnet device
instance (1600001 default for Carrier equipment).
