  • Structure
  • The MC 785-SC is a step controller that regulates a maximum of 8 compressors and 8 condenser fans on and off based on the measured suction and discharge pressure and the set setpoints.
  • The controller can be set to switch the compressors on power or operating hours.
  • Compressors of different capacities can be used.
  • The controller itself can calculate the best combination of compressors.
  • The condenser fans can be switched on or off based on the total running hours or in a fixed sequence.
  • Compressors and condenser fans can be taken out of the control e.g. i.v.m. maintenance or malfunctions.
  • A minimum and a maximum pressure alarm, a minimum and a maximum pressure alarm, a minimum and a maximum temperature alarm and a minimum and a maximum temperature alarm can be set to monitor the control. The various external faults can be reported on the step controller.
  • As soon as an external fault arrives, the relevant compressor or fan is taken out of the control so that optimal control remains possible.
  • A super-heat alarm can be set on the MC 785-SC to prevent liquid from entering the compressor.
  • All settings and operating options can be authorized by means of a password.
  • There is an RS485 network for controlling the MC785-SC from a PC, via the PC interface and a control program installed on the PC.
  • The MC 785-SC is suitable for surface mounting.
  • The MC 785-SC is supplied with 230Vac as standard.
  • On request the controller can also be supplied for a different supply voltage.
