LCD Touch-Screen Display with Multi-Language Support
The standard DynaView display provided with theTrane CH530 control panel features an LCD
touch-screen that is navigated by file tabs.This is an advanced interface that allows the user to
access any important information concerning setpoints, active temperatures, modes, electrical
data, pressure, and diagnostics. It uses full text display available in 19 languages.
Display Features Include:
• LCD touch-screen with LED backlighting, for scrolling access to input and output operating
information
• Single-screen, folder/tab-style display of all available information on individual components
(evaporator, condenser, compressor, etc.)
• Password entry/lockout system to enable or disable display
• Automatic and immediate stop capabilities for standard or immediate manual shutdown
• Fast, easy access to available chiller data in tabbed format, including:
• Modes of operation, including normal cooling as well as ice making
• Water temperatures and setpoints
• Loading and limiting status and setpoints
• Outdoor air temperature
• Start/stop differential timers
• Pump status and override
• Chilled water reset settings
• Optional external setpoints, including:
• Chilled water, demand limit, ice building
Reports, listed on a single tabbed screen for easy access, including:
• ASHRAE, containing all guideline 3 report information
• Evaporator, condenser, compressor
Evaporator, condenser, and compressor reports containing all operational information on
individual components, including:
• Water temperatures, refrigerant pressures, temperatures, and approach
• Flow switch status, EXV position, compressor starts and run-time
Alarm and diagnostic information, including:
• Flashing alarms with touch-screen button for immediate address of alarm condition
• Scrollable list of last ten active diagnostics
• Specific information on applicable diagnostic from list of over one-hundred
• Automatic or manual resetting diagnostic types
Adaptive Controls
Adaptive Controls directly sense the control variables that govern the operation of the chiller:
evaporator pressure and condenser pressure.When any one of these variables approaches a limit
condition when damage may occur to the unit or shutdown on a safety, Adaptive Controls takes
corrective action to avoid shutdown and keep the chiller operating.This happens through
combined actions of compressor and/or fan staging. Whenever possible, the chiller is allowed to
continue making chilled water.This keeps cooling capacity available until the problem can be
solved. Overall, the safety controls help keep the building or process running and out of trouble.
