Tracer CH530 Chiller Controller
Revolutionary control of the chiller,
chilled water system, and your entire
building with unprecedented
accuracy, reliability, efficiency, and
support for maintenance using the
chiller’s PC-based service tool.
Chiller reliability is all about
producing chilled water and keeping
it flowing, even when facing
conditions that ordinarily would shut
down the chiller — conditions that
often happen when you need cooling
the most.
Tracer CH530’s Main Processor,
DynaView™, is fast and keeps the
chiller online whenever possible.
Smart sensors collect three rounds of
data per second, 55 times the data
collection speed of its predecessor.
Each device (a sensor) has its own
microprocessor that simultaneously
converts and accurately calibrates its
own readings from analog to digital.
Because all devices are
communicating digitally with the
DynaView™ main processor, there is
no need for the main processor to
convert each analog signal one at a
time. This distributed logic allows
the main processor to focus on
responding to changing conditions
— in the load, the machine, its
ancillary equipment, or its power
supply. Tracer CH530 constantly
receives information about key data
parameters, temperatures and
current. Every five seconds then a
multiple objective algorithm
compares each parameter to its
programmed limit. The chiller’s
Adaptive Control™ capabilities
maintain overall system performance
by keeping its peak efficiency.
Whenever the controller senses a
situation that might trigger a
protective shutdown, it focuses on
bringing the critical parameter back
into control. When the parameter is
no longer critical, the controller
switches its objective back to
controlling the chilled water
temperature, or to another more
critical parameter should it exist.
Variable water flow through the
evaporator
Chilled-water systems that vary water
flow through chiller evaporators have
caught the attention of engineers,
contractors, building owners, and
operators. Varying the water flow
reduces the energy consumed by
pumps, while requiring no extra
energy for the chiller. This strategy
can be a significant source of energy
savings, depending on the
application. With its faster and more
intelligent response to changing
conditions, Tracer CH530 water flow
sensing option accommodates
variable evaporator water flow and its
effect on the chilled water
temperature. These improvements
keep chilled water flowing at a
temperature closer to its setpoint.
User-defined language support
DynaView™ is capable of displaying
English text or one of the two
alternate languages that are stored in
DynaView™ at one time. Switching
languages is simply accomplished
from a settings menu.
Similarly, TechView™ accommodates
a primary and a secondary language
from the same list of available
languages.
