Hardware Installation
Hardware Installation
The hardware of an LCI-C consists of a low-level intelligent device (LLID), which is an
electronic board that allows the UC800 to communicate on a LonTalk™ network. The LLID
is designed to be mounted in an enclosure so that it is protected from the environment.
The chiller’s control panel cabinet, where the other Tracer™ UC800 LLIDs reside, provides
a convenient place for the LCI-C (refer to Figure 1).
Figure 1. Chiller control panel box
To install the LCI-C LLID:
1. Use a screwdriver to mount the
LCI-C LLID in the chiller control
panel box or another suitable
enclosure.
2. Attach the Machine bus ribbon
cable to the LCI-C LLID.
3. Attach the LonTalk cable to the
LCI-C LLID.
4. Attach any necessary termination
resistors to the LonTalk link.
Note: (For Trane control systems,
refer to the Tracer
Summit™ Hardware and
Software Installation guide
(BMTX-SVN01C-EN) for
more information on where
and when to use
termination resistors.)
