  • Page 8: Design And Operating Principle

    DESIGN AND OPERATING PRINCIPLE Controller casing is made of non-flammable thermoplastic. The controller is equipped with an on/off button with backlight and an operation status indicator. Output power change from 30 to 100% is made proportionally to the control signal 0...10 V or 4-20 mA in the selected range during configuring the controller.
  • Page 9 InStAllAtIon InStrUctIonS Find a flat surface for mounting (wall, panel, etc.). Follow these steps: 1. Turn off the power. 2. Remove the front cover by removing the self-tapping screws and secure the controller to the wall or panel using screws through holes located in the back wall of the device.
  • Page 10 3. Connect the motor / fan. The connection is made using screw terminals on the controller circuit board. 4. Connect L1 output for three-wire connection, adjustable valve, etc. (if necessary). See Fig. 3. Figure 3. electrical circuit diagram Analog output 0-10 VDC / 0-20 mA Power supply Modbus...
  • Page 11 5. Select the desired analog input type and mode, start mode and shutdown level using the DIP switch on the circuit board. (See Fig. 4.). Figure 4. Setting the dIp switch ON — deceleration mode: Acceleration/deceleration 10–0 VDC / 20–0 mA mode selection OFF —...
  • Page 12 6. A network bus terminator (NBT) is used to set the device as a terminator, and by default the NBT is disabled. It is installed manually on the pins that need to be connected (see Fig. 5). To ensure correct communication, the NBT jumper must be activated only in two devices in the Modbus RTU network (see example 1 and example 2).
  • Page 13 7. Connect the power supply. 8. Adjust the max. speed using the trimmer (if necessary). The default setting is Us (230 VAC), see Fig. 6. 9. Adjust the min. speed using the trimmer (if necessary). Default is 30 % Us (69 VAC), see Fig. 7. 10.
  • Page 14 Follow the instructions below: 1. Turn on the power. 2. Set the NBT jumper, DIP switch, max. speed trimmer, trimmer for min. speed and the off level trimmer to the desired positions / values. Factory settings are as follows: • the jumper is open (the mains bus resistor jumper is disconnected); •...
  • Page 15 11. Check whether both LEDs (Fig. 9) are lit after turning on the device. If lit, your device has detected a Modbus network. If not, check the connection. Fig. 9. communication detection indication AttentIon! The status of LEDs can only be checked when power is supplied to the device. Follow all necessary safety precautions!
  • Page 16 operAtInG MAnUAl operation modes In Modbus mode you control the following parameters: Umax, Umin, fast start / smooth start, acceleration / deceleration and shutdown level values with Modbus registers. In autonomous mode you control the following parameters: Umax, Umin, fast start / smooth start, acceleration / deceleration and shutdown level values with hardware settings (DIP switch, trimmers, jumpers).
  • Page 17 led indication on the front panel When the green LED on the front panel (Fig. 10) is continuously lit, the controller is working in normal mode. If it flashes: • the controller works in remote control mode, or • the controller is turned off and the analog input signal is below the shutdown level. Fig.
