MOUNTING AND SET-UP
The controller is intended for indoor installation.
When installing the controller ensure unobstructed recirculation of air for cooling its internal elements.
Do not install the controller above heating equipment or in areas with insufficient air convection.
ATTENTION! After transporting or storing the product at sub-zero temperatures the controller must be kept
under the specied operating conditions for at least 4 hours prior to turning it on.
Inspect the product visually to confirm absence of any damage to the controller casing.
An automatic switch built into the stationary power supply network must be installed on the external input.
Note: To disable the ON / OFF function (3.0 A version only!) connect 230 VAC supply voltage to the unregulated output (L1).
In this case, do not connect the power supply unit to L.
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.
The control signal type 0...10 V or 4-20 mA is selected by a switch in the controller casing.
Controlling is possible with the use of a remote control panel, e.g. the R-1/010 controller.
The minimum rotation speed value is set by a variable resistor on the control circuit board inside the controller.
The controller has an additional terminal (230 V) for connecting and controlling external equipment (for example, air damper
drives).
The input circuit of the controller is protected from voltage and current overload by a fuse.

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. Observe the correct mounting position and dimensions of the device.
(See Fig. 1: Mounting dimensions and Fig. 2: Mounting position.)

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).

ATTENTION! Network bus terminators (NBTs) must be activated in the Modbus RTU network.
ATTENTION! If an AC power supply is used with a device in a Modbus network, DO NOT connect the GND terminal to
other network devices or via a CNVT-USB-RS485 converter. This can lead to permanent damage to the communication
semiconductors and/or the computer!

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. Adjust the off level value on the trimmer (if necessary).
The default value is 0 VAC, see Fig. 8.

11. Close the housing and secure the cover.
12. Switch on the power supply.
13. Change the factory settings to the desired ones using 3SModbus software (if necessary).

14
EN
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);
• acceleration mode: 0–10 VDC / 0–20 mA;
• OFF level;
• fast start is disabled;
• input voltage mode (0–10 VDC);
• min. settings on the trimmer for min. speed;
• max. settings on the max. speed trimmer;
• min. setting on the off level trimmer.
3. Set the analog input signal to a maximum value of 10 VDC or 20 mA.
4. The connected motor will run at a maximum or minimum speed depending on the analog input mode (acceleration /
deceleration).
5. If shutdown level is enabled and the deceleration analog input mode is selected, the motor will stop running.
6. Set the analog input signal to the maximum value of 0 VDC or 0 mA.
7. The connected fan will run at a minimum or maximum speed depending on the analog input mode (acceleration /
deceleration).
8. If the shutdown level is enabled and the acceleration analog input mode is selected, the motor will stop running.
9. If the shutdown level and the input signal are equal to the shutdown level value, the motor speed will be minimal in the
acceleration mode or maximum in the deceleration mode.
10. If the controller does not work according to the above instructions, it is necessary to check connections and settings.

15
EN
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!

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).
In normal mode, if the shutdown level is disabled, smooth start / fast start is performed only once after the controller is
powered up, otherwise smooth start / fast start is activated every time the controller is powered on.
When Timer mode is selected, the controller receives a pulse control signal from the remote control switch. When Logic
mode is selected, the controller receives a pulse control signal from the Ai input.
In both modes — Timer mode and Logic mode — the pulse width must exceed 30 ms, otherwise the signal will be filtered.

17
EN
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.
