APPENDIX D — NETWORK CONFIGURATION (cont)
MOUNTING THE BACNET DONGLE — Follow these
steps to mount the BACnet dongle in the PIC 5 control box:
1. Disconnect the PIC 5 control power supply.
2. Open the metal cover of the control box with a screw-
driver. See Fig. M and N.
3. Insert the BACnet dongle into the connector. See Fig. O.
4. Mount the plastic holder that holds the dongle to the
board. See Fig. P.
5. Close the box and power up the PIC 5 controller.
TESTING THE INSTALLATION — To verify that the don-
gle connection is correctly inserted and detected by the equip-
ment, with the controller powered up, go to the PIC 5 Main
Menu nputs Status and confirm that the BACnet Dongle
status is Yes.
BACnet Settings —
BACnet settings are available on
the Main Menu Configuration Menu CONNECT. The
menu requires the Advanced User password for access. For de-
tails, see the Network Configuration table on page 74.
BACnet Objects —
The 19XR PIC 5 contains up to 500
BACnet objects. They can be of ANALOG_VALUE (AV) or
BINARY_VALUE (BV) type. Objects name are assigned by
concatenating the CCN table name and CCN point name. This
enables easy identification and recognition of the points. For a
detailed list, see the BACnet Object table beginning on
page 98.
In general, the equipment configuration parameters are
available as Read Only. Setpoint parameters can be read and
written (Read-Write).
CAUTION
The components that make up the chiller controller include
electronic components. These may generate or be damaged
by electromagnetic interference such as electrostatic dis-
charge (ESD).
Technicians who do not have access to an ESD wrist strap
on site should follow these recommendations in order to
minimize the risk of ESD:
• Be sure to be at zero potential by touching an
unpainted surface on the electrical box.
• Do not wear clothing that tends to conduct electrical
charge, such as a wool sweater.
• Electrical storms can increase the ESD risk; unless
absolutely necessary, do not work on the chiller con-
troller during an electrical storm.
