Control Module
Trade do Brasil offers to its clients the
newest technology in microprocessed
control. The CH530 controller with the
DynaView control module. DynaView
has a touch-screen liquid crystal
display, which allows the user to
access any information related to the
configuration, operational mode,
temperatures, electric data, pressures,
and diagnostics.
Safety Controls
The controller also offers a high level
of protection to the equipment by
constantly monitoring the variables of
pressure, current, voltage, and
temperatures of the evaporator and
condenser. When one of these
variables begins to get close to a limit
condition, which could cause the unit
to shut down, the controller begins a
series of actions, such as staggering
the compressors and fans, in order to
keep the equipment in operation
before resulting in the final decision to
shut it down. Under normal operation,
the controller will always optimize the
unit's functions by staggering the
compressors and fans in order to
reach the best level of energy efficiency
within the operating condition that the
equipment currently finds itself.
External Control
The controller allows various controls
to be carried out by means of external
signals, giving more flexibility to the
equipment's operation.
Remote On/Off -
By a NC (normally
closed) contact or switch, the unit will
be able to be turned on and off
remotely.
Interlock Water Pump -
By means of
an auxiliary contact of the water pump
contactor and a flow switch, the
equipment will be informed about the
existence of water flow in the
evaporator.
Water Pump Control
- The controller
has an outlet to carry out the actuation
of the water pump contactor of the
evaporator, and an external control is
not necessary for its actuation.
Control of the Hot Gas Bypass Valve
-
When the option of the Got Gas
Bypass valve is solicited, the controller
has an outlet to carry out the valve's
operation by means of operational
information established by the
DynaView controller user.
Emergency Shutdown
- A NC contact
or external switch can be used to turn
off the unit in emergency situations,
after which a manual reactivation of
the unit will be necessary using
DynaView. This device allows the
equipment, for example, to be turned
off by a fire alarm system.
Optional Controls
Trane still offers a vast array of
controls to be used for specific
applications of each installation.
Remote Adjustment of Chilled Water
Setpoint
By means of an analog input, the
chilled water setpoint may be
controlled remotely by means of
a 0-10VDC or 4-20mA signal.
Signaling Relays
A set of 4 programmable relays may
be used to remote signal the unit's
operational status such as maximum
capacity, limit operation, compressors
in operation, and the signaling of
alarms.
Ice Making and Control of Demand
By a NO (normally open) contact, the
equipment can be turned on externally
to start up the ice making mode. By a
NC (normally closed) contact at
another inlet of this module, the
demand of the equipment can be
controlled.
COMM3 Interface
- This interface
makes it possible for the equipment to
be interlinked to Trane's control and
management system-Tracer Summit.
