T roubleshooting for RTAC and RTHD Units with T racer CH530 Controls
The purpo of this bulletin is to provide control operation and general troubleshooting information on the RTAC Air Cooled Chillers and RTHD Water Cooled Chillers with the CH530 controls. It is recommended that the rvice technician be familiar with the CH530 operation prior to rvicing the microprocessor.
This bulletin is intended to rve as a supplement to the RTAC and RTHD IOMs, the installation, operation and maintenance manuel. Subjects covered in this bulletin are intended to provide more comprehensive information for the RTAC and RTHD units.

Warnings and Cautions
Important - Read This First!This manual is intended for experienced rvice personnel familiar with the proper u of electrical diagnostic instruments and all personal safety procedures when working on live electrical circuits.
This Manual is not intended for individuals who have not been properly trained in handling live electrical circuits.
Important Environmental Concerns!Scientific rearch has shown that certain man-made chemicals can affect the earth’s naturally occurring stratospheric ozone layer when relead to the atmosphere. In particular, veral of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and tho containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing the compounds have the same potential impact to the environment. T rane advocates the responsible handling of all refrigerants—including industry replacements for CFCs such as HCFCs and HFCs.
Responsible Refrigerant Practices!T rane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified. The Federal Clean Air Act (Section 608) ts forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is ud in the rvice procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.
ƽ WARNING Contains Refrigerant!System contains oil and refrigerant under high pressure. Recover refrigerant to relieve pressure before opening the system. See unit nameplate for refrigerant type. Do not u non-approved refrigerants, refrigerant substitutes, or refrigerant additives.
Failure to follow proper procedures or the u of non-approved refrigerants, refrigerant substitutes, or refrigerant additives could result in death or rious injury or equipment damage.
NOTICE: Warnings and Cautions appear at appropriate ctions throughout
this literature. Read the carefully.
ƽWARNING: Indicates a potentially hazardous situation which, if not avoided, could result in death or rious injury.
ƽCAUTION: Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be ud to alert against unsafe practices.英语四级听力真题下载

CH530 Overview
CH530 is a distributed architecture control that puts communication capability
and some limited intelligence down at the nsor level (Low Level Intelligent
Devices, or LLIDs). Higher level modules or Super LLIDs (starter) exist only as
necessary to support system level control and communications where
subsystems require a collection of I/O and intelligence.
The primary benefit of the LLIDs architecture is the low cost of replacement parts.
CH530 architecture allows a single point to be replaced with only pig-tail wiring
and electronics dedicated to a particular point.
Main Processor
The main processor is the “master of the chiller” by collecting data, status, and
diagnostic information and communicating commands to the other modules
联系人的英文缩写(starter) and the LLID bus. The communications bus is called the Inter-Processor
Communications. The main processor is located in the human interfaces
(DynaView, EZView).
mdl
Starter Module
The starter module provides control of the compressor contactors when starting,
running, and stopping the chiller. Starter types include Across the Line (RTAC),
Y-Delta and Solid State (RTHD). The starter module provides protection of the
compressor in the form of running overload, pha reversal, pha loss, pha
imbalance, and momentary power loss.
Power Supply Module
The power supply module provides 24VDC power to support all of the module

and LLIDs functions.
LLIDs (Low Level Intelligent Devices)武汉出国中介
The following devices are types of inputs and outputs that exist as LLIDs. Some
of the LLIDs are optional. The number and type of LLIDs are dependent on the
unit size and configuration.
