Diagnostics
The absorption chiller Unit Control Panel (UCP2) provides
over 70 active and historic diagnostics such as:
• Water and refrigerant/solution temperatures out of
range
• Solution pressures out of range
• Loss of system water flows
• Sensor and switch faults
• Overload trips
• Over/under voltage (optional)
• Crystallization recovery
• High pressure cutout
• Emergency stop
• Loss of communication to other modules
• Motor abnormal
Operator Interface
The Trane Horizon ™ steam-fired absorption chiller
control panel, UCP2, is easy to use, understand, access information, read, change
setpoints, diagnose problems, maintain, and to reset after shutdown.
Convenience
Enunciation of all information is at the front panel
display (including power, voltage, amps, purge pressures, and number of starts data).
Messages displayed using clear language.
Readability
• Two line, 40 character display that is easy to read
from within a 60 degree angle
• LCD backlight so that the display can be read in a
variety of equipment room lighting
Remote Operator Interface
With the addition of an optional remote interface panel, up
to four chillers with UCP2 can be monitored and controlled. All data available at each
chiller’s local operator interface is available to the Remote Operator Interface via
a single twisted pair.
Ease of Use
• Keypad programmability —no manual switches or
setpoint potentiometers
• Logically arranged report groups with report header
and setpoint groups
• Selectable security
• Variable points updated every two seconds
• Messages that direct user to problem source via a
menu item
Application Flexibility
• Seven languages available
• Metric (SI) units available
• Complete character human interface available
Trane ICS Compatibility
The Trane Absorption chiller control panel, UCP2, is 100
percent compatible with the Trane Integrated Comfort™ systems, ICS, UCP2 easily integrates into the Tracer ® family of flexible
chiller plant system controllers with a single twisted-wire pair communications cable.
