Digital controllers

Digital controllers CooltechCOOLTECH CTSCC-50 controller is used to control such working parameters as temperature and pressure of suction, discharge and oil.

Menu settings are available to control oil pump, heaters, economizer, displacement valve and step drive systems. Control parameters, operating mode, trip settings and timing may be changed locally at the control panel as well as remotely from the RS485 Supervisory Alarm Monitor System PC or the TCP/IP network. Optionally SNMP-protocol can be included for controlling and Web page displays as well as standards RS485 MODBUS, PROFIBUS.

Main advantages:

  • Suction pressure, discharge pressure or process temperature control.
  • Automatic control of motor, slide, pump, economizer and oil heater
  • Stepper motor control of Auto Variable Vi slide
  • Stepless capacity control
  • Alarm and trip monitoring of all variables and trip states
  • Simultaneous SNMP & RS485 MODBUS, PROFIBUS protocols
  • Fault input displays for all compressor safety inputs
  • Variable frequency control of compressor’s motor
  • Condenser blowers control
  • MotorAmps alarms, display and automatic slide unload
  • Multi-compressor operation on same suction line
  • Simple button operation of easily read LED display panel
Main technical characteristics:
  • Different languages on display panel upon request;
  • Two communicational ports using RS485 MODBUS, PROFIBUS protocols;
  • Internet protocol option (TCP/IP);
