General information
Foreword
These Installation Operation and Maintenance instructions are given as a guide to good practice in the installation, start-up, operation and periodic maintenance by the user of TRACER CH532 chiller controller. They do not contain the full service procedures necessary for the continued successful operation of this equipment. The services of a qualified service technician should be employed, through the medium of a maintenance contract with a reputable service company.
Warranty
Warranty is based on the general terms and conditions of the constructor. The warranty is void if the equipment is modified or repaired without the written approval of the constructor, if the operating limits are exceeded, or if the control system or the electrical wiring is modified. Damage due to misuse, lack of maintenance, or failure to comply with the manufacturer’s instructions, is not covered by the warranty obligation. If the user does not conform to the rules of “Maintenance”, it may entail cancellation of warranty and liabilities by the constructor.

Hardware architecture
TRACER CH532 offers customer the
possibility to use inputs or outputs in order to:
- use an external water setpoint reset using an analog input (refer to figure 3)
- use an auxiliary setpoint
- connect a remote on/off of the unit or a circuit
- reset faults
- connect a remote Cooling/Heating switch
- return a circuit fault
Note: External water setpoint
Based on a external signal input, it will be possible to offset the active setpoint from 0°C to 20°C. This function can be used in conjunction with the automatic setpoint reset function.

Alarms
1. Alarms display and Resetting
A fault on a unit will be shown through the user interface or through 2 digital outputs, one for each refrigerant circuit.
The alarms are divided into 3 categories:
- Warning. Shows that something is
wrong on the unit but unit can be kept in operation. A message is displayed on the user interface screen. These messages are not recorded in the history list.
- Fault with automatic reset: when
the cause of the fault disappears, the fault is cancelled and unit operation will return to normal. The messages displayed on the user interface screen disappear but are recorded in the history list of faults. The fault is relayed through the digital output if I/O parameter is set to show a circuit fault.
- Fault with manual reset: when the
cause of the fault disappears, a manual reset is required to restart the unit. The messages displayed on the user interface screen disappear and are recorded in the history list of faults. The fault is relayed through the digital output if I/O parameter is set to show a circuit fault.
2. Alarms history
200 events can be recorded by TRACER CH532. Each record will give the fault description, the reset type, the order and the day and time of occurrence.
Maintaining for 5 seconds give will access to the last event recorded.
Then using allows the user to view the complete history. (refer to table 5 for possible messages)
Should an alarm occur, will be lit in red.
Pressing once will display the alarm message (refer to table 4 for possible messages) When alarm message is displayed
press to reset the default if necessary.

Description
The Lon interface uses an Echelon FTT-10 transceiver, which is approved to be used on the TP/FT-10 channel. This channel is characterized by the following main features:
• It consists of up to 60 nodes on a single network segment
• Data rate : 78 125 kbps
• Maximum distance : 1400 meters
• Recommended topology : daisy chain with double end terminator (105 ohms)
For futher details, refer to the official documentation LonWorks®FTT-10A free topology transeiver user’s guide and to the official LonWorks guidelines LonMark®layer 1-6 interoperability guidelines version
3.0.

To activate the service pin, simply short circuit the two pins for a moment using the tip of a screwdriver or similar tool. The service pin is available only in the node installation phase. When the pin is activated, the node sends a broadcast message in the LonWorks®containing the necessary information in order to be identified.

Cable characteristics
Level 4 cable may be used with TP/FT-10 channels. The level 4 cable specification used by Echelon and as originally defined by the National Electrical Manufacturers Association (NEMA) differs from the Category 4 specification proposed by the Electronic Industries Association / Telecommunication Industries Association (EIA / TIA). The following specifications can be used by cable suppliers to identify a compliant Level 4 cable.
Specifications apply to shield or unshielded 22AWG (0.65mm2) cable

Safety recommendations
To avoid accidents and damage, the following recommendations should be observed during maintenance and service visits:
1. The maximum allowable pressures for system leak testing on low and high pressure side are given in the chapter “Installation”. Always provide a pressure regulator.
2. Disconnect the main supply before any servicing on the unit.
3. Service work on the refrigeration system and the electrical system should be carried out only by qualified and experienced personnel.
Maintenance contract
It is strongly recommended that you sign a maintenance contract with your local Service Agency. This contract provides regular maintenance of your installation by a specialist in our equipment. Regular maintenance ensures that any malfunction is detected and corrected in good time and minimizes the possibility that serious damage will occur. Finally, regular maintenance ensures the maximum operating life of your equipment. We would remind you that failure to respect these installation and maintenance instructions may result in immediate cancellation of the warranty.
Training
The equipment described in this manual is the result of many years of research and continuous development. To assist you in obtaining the best use of it and maintaining it in perfect operating condition over a long period of time, the manufacturer has at your disposal a refrigeration and air conditioning service school. The principal aim of this is to give operators and technicians a better knowledge of the equipment they are using, or that is under their charge. Emphasis is particularly given to the importance of periodic checks on the unit operating parameters as well as on preventive maintenance, which reduces the cost of owning the unit by avoiding serious and costly breakdown.
The manufacturer has a policy of continuous product improvement, and reserves the right to alter any details of the products at any time without notice.
