Integrated all pole effective sine filter
Phase to phase and phase to grounded conductor which means sinusoidal output voltage. Measures typical for frequency inverters such as shielded motor feed lines are not required.
LC-multifunction display with plain text:
Various menu languages can be selected
Simple commissioning through operating modes:
Typical operating modes, e.g. for air-conditioning, refrigeration or ventilation technology can be selected.
Easy to program:
Typical settings can be made: e.g., default a minimum speed, limit the maximum speed, inverting and limits. Setting, e.g. for 2-stage mode
2 analogue inputs for sensors or setpoint signals:
Analogue input E1 and E2: Setting through operating modes or manually programmable, e.g. 0-10 V, 0-20 mA, 4-20 mA
Analogue input E2: programmable, e.g. comparison to Sensor 1, difference to Sensor 1, average calculation, setpoint input, setpoint adjustment (e.g. dependent on outdoor temperature)
Two digital inputs. D2 and D1:
Programmable, e.g. enable, switchover Setpoint 2 or 1 switchover control or manual operation, switchover E2, or E2, reverse control function, limit output, display of external fault, reset, reverse the rotary direction
2, analogue output A1:
Setting through operating modes or manually programmable, e.g., output signal proportional modulation, output signal proportional input signal, invertible, 10 V constant voltage, group control
10 digital outputs (relays) K1 and K2:
Setting through operating modes or manual programming, e.g. operating status, limits, external fault on digital input, enabling external devices, e.g. heating, dampers, group control of fans, etc.
Integrated motor protection function:
Connection facility for PTC thermistors or alternatively thermostats (TB or TP).
Interface RS485 MODBUS RTU:
Integration into bus system
Setting protection / memory for settings:
Enable settings protection from unauthorised access, restore implemented settings
Query events that have occurred, operating times, etc.
