Optional Relay Circuits
Optional Control and Output Circuits
Install various optional wiring as required by the owner's specifications.
Optional Tracer
Communication Interface
This control options allows the unit control panel to exchange information such as
chiller status and operating set points with a Tracer system.
Figure 31 illustrates how such a communication control network might appear.
Note: The circuit must be run in separate conduit to prevent electrical noise interfer-
ence.
Additional information about the Tracer Communication options is published in the in-
stallation manual and operator's guide that ships with the Tracer.
Unit Start-Up
All phases of initial unit start-up must be conducted under the supervision of a quali-
fied local service engineer. This includes pressure testing, evacuation, electrical checks,
refrigerant charging, actual start-up and operator instruction.
Advance notification is required to assure that initial start-up is scheduled as close to
the requested date as possible.
Starter Module Configuration
The starter LLID configuration settings will be checked (and configured for Remote
Starters) during start-up commissioning.
To configurate starter module, and perform other starter checks, it is recommended
that the line voltage three phase power be turned off and secured (locked out), and
then a separate source control power (115 Vac) be utilized to power up the control cir-
cuit. To do this, remove control coil circuit fuse, typically 2F4, and then connect sepa-
rate source power cord to starter terminal block 2X1-1 (H), 2X1-2 (N), and Ground. Use
the as-built starter schematic to assure correct fuse and terminals. Verify correct fuse
is removed, control circuit connections are correct, then apply the 115 Vac separate
source power to service the controls.
Forms Information
Samples of start-up and operating forms along with other helpful forms are found in
the Operation Maintenance manual which can be obtained from the nearest Trane of-
fice.
It is recommended that the serviceman contact the local Trane office to obtain the
most recent printing date of the form. The forms in the operation and maintenance
manual are only current at the time of printing of the manual.
After obtaining the most recent form, complete all the information and forward it to
your local Trane office.
