product introduction:The new microcontroller based FKD331 is a multistage electronic capacity controller for multi-cylinder reciprocating compressor or rack systems. LCD Based unit has easy to use settings, like Set point -Low pressure (LP), Neutral Zone (NZ) & Interstage timer. One Analog input (4 to 20mA) for pressure transmitter e.g. compressor suction or RTD Pt100 One Digital input (potential free) for Compressor On feedback Four / Six Relay Output for Compressor Capacity Control Solenoid Valves and Compressor trip Adjustable Neutral Zone, time delay, Calibration Optional RS232 / RS485 port for communication Optiona l available Software for PC monitoring Function Capacity regulation.The cut-in capacity is controlled by signals from the connected pressure transmitter and the set reference. Outside the reference a neutral zone is set where the capacity will neither be cut in nor out. Outside the neutral zone the capacity will be cut it or out in the regulation registers a deviation then a change will take place accordingly with the set time. If the pressure however “approaches” the neutral zone, the controller will make no changes of the cut-in capacity. Cut-in of steps are defined for either sequential or cyclic operation. Separate compressor trip point can be set to trip compressor.
