Startup

Connecting LLIDs onto the inter-processor communication
(IPC) bus
Starting at the power supply, connect all LLIDs together to form the IPC bus using
the IPC bus cable with connectors. Either the J1 or the J11 connection on each LLID
may be used. Cut off extra cable and seal ends using CAP00876 and ADH00023.

Current transformer (CT) work

Three new CTs must be installed to complete this installation. The new CTs are not
included in this KIT. They must be ordered separately. See Table 1 in Appendix C for
details.
Before installing these CTs use a digital multi-meter, with phase detection capability
to identify and mark incoming power, L1, L2 and L3 or phase A, B, and C.
Install the new CTs as shown on the wiring diagram in Appendix B. Pay careful
attention to the polarity dot and it's orientation.
Wire the leads from the spade connectors to the starter module as shown on the
wiring diagram.

The following table describes the steps to take the controls from "installed" to
"operational" . Specific details on certain steps (configuration, binding, etc.) are
contained in appendices referenced in the particular step.
WARNING
Live Electrical Components!
During installation, testing, servicing and troubleshooting of this product, it
may be necessary to work with live electrical components. Have a qualified
licensed electrician or other individual who has been properly trained in
handling live electrical components perform these tasks. Failure to follow all
electrical safety precautions when exposed to live electrical components may
result in death or serious injury.
1. Obtain CH530 Software: From http://www.trane.com/commercial/software/
tracerch530/, download the latest Java™ runtime, TechView™, and MP software.
Select CVR software from drop-down list. After downloading be sure to install all
files in the proper order following instruction provided on this website.
2. Run TechView on laptop and connect RS232 cable from laptop to DynaView.
3. Unplug the IPC bus (including DynaView) from the power supply LLID: this will
isolate the power supply LLID.
4. "Power Up" the existing control panel using auxiliary power.
5. Re-connect IPC bus to power supply and DynaView.
6. From the Chiller Software tab in TechView, download "CVR" MP software onto
DynaView.
7 . Configure the software in TechView using the "Unit Type" , "CH530" , and "Starter"
