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 UCP
to exchange information such as
chiller status and operating set
points with a Tracer system.
Note: The circuit must be run in
separate conduit to prevent electrical
noise interference.
Additional information about the
Tracer Comm option is published in
the installation manual and
operator's guide that ships with the
Tracer.
See Table 15 for Tracer Connections.
Note: Comm 4 will require Tracer to
be connected to each panel for
individual circuit information.
(Comm 5 will require connections to
the left panel only when available.

Electrical
Information
Unit Start-Up
All phases of initial unit start-up must
be conducted under the supervision
of a qualified Trane 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 module configuration
settings will be checked (and
configured for Remote Starters)
during start-up commissioning. To
configurate starter modules, 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 circuits. To do this, remove
control coil circuit fuse, typically 2F4,
and then connect separate source
power cord to starter terminal block
1X1-5 (L1), 1X1-17 (L2), and Ground.
This needs to be done in each panel.
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
office.
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.
