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. temperature and pressure sensors, low voltage binary inputs, analog input/output) all connected to a
•The communication interface to a building automation system (BAS).
•A service tool to provide all service/maintenance capabilities. Main processor and service tool (TechView) software is downloadable from www.Trane.com. The process is discussed later in this section under TechView Interface. DynaView provides bus management. It has the task of restarting the link, or filling in for what it sees as "missing" devices when normal communications has been degraded. Use of TechView may be required.
The CH530 uses the IPC3 protocol based on RS485 signal technology and communicating at 19.2 Kbaud to allow 3 rounds of data per second on a
Note: It is imperative that the CH530 Service Tool (TechView) be used to facilitate the replacement of any LLID or reconfigure any chiller component.
Controls Interface
DynaView (picture on cover)
Each chiller is equipped with the DynaView interface. DynaView has the capability to display additional information to the advanced operator including the ability to adjust settings. Multiple screens are available and text is presented in multiple languages as factory- ordered or can be easily downloaded online.
TechView
TechView can be connected to the DynaView module and provides further data, adjustment capabilities, diagnostics information, downloadable software, and downloadable languages.
