Industrial controller designed for medium power compressors (up to 110 kW), with direct control and star-delta engine start up.

MS385  enables the measurement and control of:

• pressure in 4-20mA standard
• oil and air temperature sensor (PT100) and the compressor motor temperature sensor (KTY84)
• compressor motor current 
• phase asymmetry and the phase control module using the ASKF3B or two-state module
• control of digital sensors as standard 24VDC

MS385 - protection against:

• engine overheating
• breakdowns of sensors
• exceeding the maximum programmable number of starts per hour engine
• power outages
• phase reversal
• imbalance of supply voltage above the set level
• power surges and electromagnetic interference within the allowable range

MS385 - menus and functions: 

• Configurable parameters of the compressor with the division on service's and user's
• Reading the settings and current values ??of sensors in the next menu on the display
• Selection of operating mode (automatic, continuous, remote)
• 6 LEDs informing about the current state of the compressor
• Setting the operating pressure range and the critical pressure
• Indication of errors and events, and view the history of last 30 faults
• Service Counters (for worn elements) and the work counters
• Control of the heater or dryer with drying time setting
• Fan control based on temperature sensor value
• A compressor restart after power failure
• Option of remote control of the compressors operation by a master controller MS4CMPXv2 or MS585 that acts as a master controller
• The network compressor mode (up to 4 compressors) in a sequential or cascade mode without MS4CMPXv2 master controller
• Function of work planning in real time
• Communication with PC (Modbus RTU) - visualization system
• Power supply voltage of  230VAC.
