[DX220] 2-Cycle Screw Refrigerator (Chiller,CDU) Controller - stepless control
call
- [DX220] 2-Cycle Screw Refrigerator (Chiller,CDU) Controller - stepless control
- Microprocessor-based DX220 controls the timing of capacity
adjustment for energy saving and ensures the best control and safety
with the perfect interface for safety devices.
- Efficient stepless control and convenient operation and maintenance
- One-touch setup by brand(Bitzer, Fusheng, Hanbell, Hitachi, Kobe, Mitsubishi, Roltec, and Refcomp)
- Powerful timers(step delay, start delay, auto-stop delay, restart delay, and pump-down delay)
- Temperature and pressure control(inlet/outlet temperature, intake pressure, and discharge gas) -
- High Performance RISC Micom
A high performance RISC micom integrates operations and controls
digitally and precisely. It handles the instructions really fast and
reduces the risks with high sample rates.
Large Display and Easy-To-Use User Interface
A 5" LCD of 240X128 resolution supports the multilingual(English,
Japanese, Chinese, and Korean language) texts and images for users. Any
operators can select all the menus by following the steps on the screen.
It is as easy as your fingertips.
Operation Status Display
DX220 displays the operation status of a compressor and waiting time.
Compact Size, Simple Operation, and Intelligent Multifunctions for Screw Compressors
Integrating modules of control and display makes it possible to be
compact and reliable. It can be installed almost everywhere, even at
small spaces, and applied to various screw compressors. With the
real-time information on the screen and simple operation as well as
intelligent multifunctions, operators can handle the situations without
problem and save the time, money, and efforts for maintenance.
Trip Data Log
DX220 records the important data such as trip is recorded and traces
up to 160 events. It provides the useful information for analysis and
troubleshooting including history while tripped.
Noise-Free Solutions
Digital I/O signals are completely insulated to block the signals from
outside affecting the mainboard. There are safety functions in CPU.
Brownout monitors the control power in real time and watchdog checks the
status continuously(every 32msec) and makes it recover from CPU down by
noise automatically.
Scalability
RS485 port, MODBUS RTU stnadard protocol, MMI software, and automatic interface are supported.
