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 19 illustrates how such a
communication control network
might appear.
Note: The circuit must be run in
separate conduit to prevent
electrical noise interference.
Additional information about the
Tracer Communication options
is published in the installation
manual and operator's guide
that ships with the Tracer.

Installation:
Electrical
Unit Start-Up
All phases of initial unit start-up
must be conducted under the
supervision of a qualified 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 circuit. To do this,
remove control coil circuit fuse,
typically 2F4, and then connect
separate 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 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.
