2.DESCRIPTION
O
RCK-602
plus
is the first electronic controller of the
Rackontrol
line, designed for compression
centrals for commercial and industrial refrigeration applications with low and medium temperature.
RCK-602
plus
controls and monitors pressure or temperature using up to six configurable sensors, allowing the use of backup
sensors that come into operation automatically if the need arises, thus increasing the robustness of the refrigeration
system.
RCK-602
plus
is a product dedicated to the control of condensing units and rack-type parallel
compression systems by means of eight compressor or fan outputs divided into two analog outputs for proportional
control and six digital relay outputs.
The controller features a new control logic intended to minimize the power consumption of the refrigeration
system: The Progressive Algorithm seeks to match the refrigeration demand required by the plant with the power of
the compressor set, reducing the number of starts and stops. In addition, it has a function for floating cooling control,
which monitors the temperature of the external environment to reduce the cooling setpoint, consequently
decreasing the compression ratio and thus the power consumption of the system.
RCK-602
plus
features a user-friendly interface with high brightness OLED display, six interaction keys
and control menu that shows the commands most commonly used by the compression center. Simple to operate and
configure, Rackontrol features an internal buzzer (audible warning), unique key and screens for alarm monitoring
that simplify the process of monitoring and troubleshooting the refrigeration system. The real time clock (RTC)
allows automating commands and recording the times of alarm occurrences. The USB connection allows
downloading the configuration parameters and updating the firmware.
