DK-45 MK2 User Manual
DESCRIPTION
DK-45 MK2 is a high-tech product providing control of
screw or piston type air compressors driven by electric
motors.
The controller incorporates all functions needed in a
compressor control panel; thus, it eliminates the need
for additional modules, resulting in lower panel cost.
The early start function analyzes the air consumption
trend and runs the compressor so that the pressure
never falls below the low limit.
Using the Weekly Schedule and Pressure Calendar
functions, the compressor can be scheduled to work on
given hours and days of the week with given set
pressure values.
The unit is directly supplied from the 380/220V utility
network. It provides fail contact and sensor supplies
internally, removing the need for a supply transformer
in the panel.
Utility mains voltage and frequency can be read on the
unit. It offers low/high voltage and phase order
protection.
The 2.9" wide, 128x64 pixel graphical screen displays
values with graphic support.
RS-485 MODBUS RTU and USB communication ports
allow monitoring and parameter setting via PC.
Optically isolated digital inputs feature noise filtering,
allowing fault-free operation in electrically noisy
environments.
The unit has 5 relays with 5A output current.
The unit may be configured from the front panel or
using the free software Rainbow Plus, available at the
manufacturer's website.
It is possible to monitor and record the unit using the
free RAINBOW+ software.
