Overview The Trane CH530 control system that runs the chiller consists of several elements: • The main processor collects data, status, and diagnostic information and communicates commands to the LLID (for Low Level Intelligent Device) bus. The main processor has an integral display (DynaView). • LLID bus. The main processor communicates to each input and output device (e.g.
DynaView Interface The display on DynaView is a 1/4 VGA display with a resistive touch screen and an LED backlight. The display area is approximately 4 inches wide by 3 inches high (102mm x 60mm). CAUTION! Equipment Damage! Putting excessive pressure on the touch screen could cause damage. It takes less than 7 kg of force to break the screen. In this touch screen application, key functions are determined completely by software and change depending upon the subject matter currently being displayed.
DynaView Interface The bottom of the screen (7) is present in all screens and contains the following functions. The contrast (8,9) may require re-adjustment at ambient temperatures significantly different from those present at last adjustment. The other functions are critical to machine operation. The AUTO and STOP keys are used to enable or disable the chiller. The key selected is in black (reverse video). The chiller will stop when the STOP key is touched and after completing the Run Unload mode.
DynaView Interface Main Screens The Main screen shall be the default screen. After an idle time of 30 minutes the CH530 shall display the Main screen with the first data fields. The remaining items (listed in the following table) will be viewed by selecting the up/down arrow icons.

DynaView Interface Diagnostics Screen The diagnostic screen is accessible by depressing the Alarms enunciator A scrollable list of the last (up to 20) active diagnostics will be presented. Performing a Reset All Active Diagnostics will reset all active diagnostics regardless of type, machine or refrigerant circuit. Compressor diagnostics, which hold off only one compressor, will be treated as circuit diagnostics, consistent with the circuit to which they belong.
TechView Interface TechView is the PC (laptop) based tool used for servicing Tracer CH530. Technicians that make any chiller control modification or service any diagnostic with Tracer CH530 must use a laptop running the software application "TechView." TechView is a Trane application developed to minimize chiller downtime and aid the technicians' understanding of chiller operation and service requirements.
TechView Interface Software Download Instructions for First Time TechView Users This information can also be found at http://www.trane.com/commercial/s oftware/tracerch530/. 1.

Diagnostics A Valid Configuration is Present A valid configuration is present in the MP's nonvolatile memory. The configuration is a set of variables and settings that define the physical makeup of this particular chiller. These include: number/airflow and type of fans, number/and size of compressors, special features, characteristics, and control options. Temporary display of this screen is part of the normal power up sequence.
Diagnostics Programmable Relays (Alarms and Status) CH530 provides a flexible alarm or chiller status indication to a remote location through a hard wired interface to a dry contact closure. Four relays are available for this function, and they are provided (generally with a Quad Relay Output LLID) as part of the Alarm Relay Output Option. The events/states that can be assigned to the programmable relays are listed in the following table and through a TechView configuration.
