Description
LCM is an analog controller designed to operate in master mode, with proportional controller output through phase-cut control balanced with the main supply. It is ideal for the control of single-phase asynchronous motor speeds (class F) installed on axial, radial or centrifugal fans, guaranteeing accurate, efficient operation in air-conditioning, refrigeration, heating, ventilation, destratification, thermoventilation and air purifying systems.
Available in the 8 A version, LCM enables continuous modulation of the AC from 0% to 100% based on the differential between the command signal and the setpoint set.It has an analog input for the master mode, compatible with 4-20 mA pressure transducers.
The integrated functions include a remote stop contact which helps synchronize the start up of ventilation with the compressor function or other external events, thereby optimizing controller mode.
LCM includes protection of the command input, protection against power surges up to 275 Vac, complete galvanic isolation between network and signal circuits, Class B EMC filter and full compatibility with the main earthing systems (IT, TT, TN).
LCM’s compact architecture and ease of use makes it a robust, effective solution to efficiently manage fan units.
Inputs, outputs and connectivity
- Analog control input: 1 4-20 mA input for pressure transducer
- Auxiliary on-off contact: remote stop
Special features
- Accurate control of the setpoint through configurable rotary switches and jumpers.
- Choice of proportional band (Pb1, Pb2, Pb3) to optimize the system’s response.
- Protection circuit against power surges of up to 275 VAC.
- Monitoring of 4-20 mA input to avoid anomalies.
- Protection against EMC noise.
- LED to show the operating status (power supply, stop, position compared to the setpoint).
