Optional Control and Output Circuits
Install various optional wiring as required by the owner’s
specifications. Refer to Table 15, p. 49.
Optional Tracer Communication Interface
This control option allows the control panel 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 and operator’s guide that
ships with the Tracer.
Unit Start-Up
All phases of initial unit start-up must be conducted un-
der the supervision of a qualified Trane technician. This
includes pressure testing, evacuation, electrical checks,
refrigerant charging, actual start-up and operator instruc-
tion. Advance notification is required to assure that initial
start- up is scheduled as close to the requested date as
possible.
Starter Module Conguration
The starter module configuration settings will be checked
(and configured for Remote Starters) during start-up
commissioning. To configure starter modules, and per-
form 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 connect separate source power cord to starter termi-
nal block 120 V source connect, 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.
Schematic Wiring Drawings
The chart below consist of typical wiring drawings for a
CenTraVac chiller available through e-Library. However,
please refer to the submittals and drawings that actually
shipped with the unit. Additional wiring drawings for
CenTraVac chillers are available from your local Trane
office.
