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.

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.

coupling loss for any pair combination at room temperature is to be greater than the value determined using the
formula NEXT (F MHz)>NEXT (0.772)-15log10(F MHz / 0.772) for all frequencies in the range of 0.772 MHz for a length
of 1000 feet.

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
installation and maintenance
instructions may result in immediate
cancellation of the warranty.
