Tracer® Chiller Plant Manager
Easy Chiller System Logging
The UCM displays data required to log the chiller system.
The following information is available either as standard or as an option with the
Air-Cooled Series R Chiller microprocessor:
- Entering and leaving chilled water temperatures
- Ambient air temperature
- Evaporator and condenser refrigerant temperatures and
pressures
- Compressor suction temperature
- Percent RLA for each compressor
- Percent line voltage
- Compressor starts and running hours
- Active setpoints:
chilled water setpoint
current limit setpoint
ice termination setpoint
low ambient lockout setpoint
- Over 90 diagnostic and operating conditions
- Part failure diagnostics: water temperature
sensors refrigerant temperature sensors compressor contractors
Remote Display Panel
Trane air-cooled Series R® chillers are
available with a twisted pair connection to an optional remote display panel.
Chiller operation can be controlled similarly to the control interface on the chiller
itself. Through a twisted pair of wires the unit can be turned on or off, change the
chilled water setpoint, and display over 90 operating and diagnostic conditions. The
remote display panel can be mounted indoors so access to chiller information is just steps
away, eliminating any need to go outdoors or on the roof.
Remote display panels designed for air-cooled chillers of
130-400 ton ranges can control one unit. However the newly designed clear language display
for chiller sizes of 70-125 tons has the ability to control multiple units. In a multiple
unit configuration, the Remote Clear Language Display Panel has the capability to
communicate with up to four units. Each unit requires a separate communication link with
the Remote Display Panel.
Easy Interface To The Building Management System
Controlling the air-cooled Series R chiller with building
management systems is state-of-the-art yet simple.
Chiller inputs include:
- Chiller enable/disable
- Circuit enable/disable
- Chilled water setpoint
- Current limit setpoint
- Ice making enable
Chiller outputs include:
- Compressor running indication
- Alarm indication (CKt 1 /CKt2)
- Maximum capacity
Trane Chiller Plant Manager/lCS
The Tracer® Chiller Plant Manager Building
Management System provides building automation and energy management functions through
stand-alone control. The Chiller Plant Manager is capable of monitoring and controlling
your entire chiller plant system.
Application software available:
- Time-of-day scheduling
- Duty cycle
- Demand limiting
- Chiller sequencing
- Process control language
- Boolean processing
- Zone control
- Reports and logs
- Custom messages
- Run time and maintenance
- Trend log
- Totalizing
- PID control loops
And of course, Trane’s Chiller Plant Manager Panel can
be used on a stand-alone basis or tied into a complete building automation system. |
