TRACER CH532 Presentation  
Important note:This document  
describes all the functions available  
onTRACER CH532 with software  
version 2.0 and explains how to  
program it.  
Certain parameters must only be  
modified by qualified personnel.  
Before changing any parameter,  
always check that the change does  
not affect the good and safe  
operation of the equipment.  
Operation must always stay in the  
catalogued limits.  
Built-in control terminal features:  
An LCD display (1), 4 lines x 20  
characters with back lighting  
6 buttons (2) to (7)

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.

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.  
Then using

- 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

LonTalk option  
Description  
The Lon interface uses an Echelon  
FTT-10 transceiver, which is  
approved to be used on theTP/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

Cable characteristics  
Level 4 cable may be used withTP/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.

For theTP/FT-10 channel operating in a bus topology , the maximum bus length of level 4 22AWG (0.65 mm ) cabling is  
1400 meters with a maximum stub length of 3 meters.  
It is recommended to use shielded cable if high amplitude modulation noise exist or transient protection is required.

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  
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  
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
