PRELIMINARY INSPE TIONS - WARRANTY
Before installing the controller, make sure that it has not been damaged during the carrying and that it corresponds
to the model ordered. Check that the technical specifications listed in the label match with those written in the
delivery note and in the order form. The controller is covered by a 12-month warranty starting from the delivery. The
warranty covers production defects not due to damaging or wrong use, for goods returned to us X-WORKS. Any
damage occurred during the carrying shall be reported to the carrier in with the local legislation.
DISPOSAL
The sign marked on the equipment indicates that it is not to be considered as a normal domestic waste, therefore it
has to be disposed of in a specific electrical and electronic equipment recycling point.

VRTMT – USE FEATURES
The VRTMT electronic controller is normally used to control the speed of AC fans, pumps and centrifugal pumps. It is
based on the principle of symmetrical phase partialisation and It is suitable for adjustable voltage motors. VRTMT
operates on the basis of the inputs received through the measurements, the parameters settings values, the
controlling I/O and the control panel. The control panel is used to set the parameters values and read the
information about the unit status. VRTMT is provided with Modbus connection to dialog with a supervising remote
device.

According to safety directive, reference standard N60730-1. According to electromagnetic directive, reference
standard N 61800-3. With refer to some typical applications, the VRTMT8-12-20 regulators are suitable for
residential and commercial ambients, while the VRTMT28-40-50-60 regulators are suitable for industrial ambients.
VRTMS regulators are designed to be installed inside a machine or a standard electrical cabinet and are therefore
considered a component. The installer must guarantee that the machine conforms to such regulations.

ME HANI AL INSTALLATION
The VRTM regulator must be wall-mounted vertically, in order to guarantee adequate dispersion of heat in the area
of air circulation and prevent obstructions to air flow in the dissipator zone.
VRTMT has IP55 grade protection, anyway protect it from corrosive liquids, gas, heat sources and position it
preferably sheltered from the sun's rays. Make sure that it does not undergo vibrations.

ELE TRI AL INSTALLATION
Loosen the screws and remove the cover completely before performing wiring. Connect the power wires and ground
to the appropriate regulator terminals. Custom (+S ) Controls with ground conductor section less 10mmq require
double earthing connection obtainable through the grounding of the aluminum heatsink. To avoid dispersion
currents, the motor earth cable must be connected to the appropriate motor terminal ground. We recommend to
connect to the machine’s safety circuit any thermal motor protector in order to remove the control power supply
and protect the motor with maximum efficiency. The thermal motor protector may be otherwise connected directly
to the I4 control card’s terminal. If the length of the motor cable exceeds 10 metres, we suggest to use shielded
cable. The control load (min. current out >200mA) can consist of several engines provided the sum of the rated
currents of the motors is less than 20% of the rated current of the control. We recommend not introduce any
electromechanical device on the motor cable. If the control cable length exceeds 3 metres, we suggest to use
shielded cable, connecting the shield only on the regulator. We suggest don’t connect the control 0volt to the earth.
If the length of the power, motor and control cables exceeds 10m, make sure they are separated by at least 0.3
metres to avoid creating a coupling effect.
If controls are set up in environment subject to electromagnetic disturbance, they should be housed inside a suitable
metallic enclosure. In order to prevent the formation of condensation and regular working also cold temperature it is
recommended you insure a constant power supply, avoiding turning it off continually.
All connections wires must resist to a 80°C working temperature.
Avoid routing any electric wires near the copper coils of the filter, use the suitable plastic
support ! Tighten all wires on control and power terminal boards fully down, avoiding
protrusion of the multi-stranded wire.
Do NOT touch the electronic equipment when the power line is on !
During voltage insulation tests disconnect the regulator power lines In/Out.
Use a true RMS tester to measure the current or voltage values.
The cover must be closed by screwing the screws with a torque of 1.2 Nm.
In the event that regulator operation failure could cause damage to objects or physical
injury, it is the responsability of the installer to add devises or systems that protect against,
or warn of, control failure.
Check the position of the voltage change jumper according to the
supply voltage available, to the type of control (see coding
paragraph page 3, pos.3) and to the panoramic view of the
corresponding card.
To protect the power line and the regulator, the installation technician
must install extra-rapid semiconductor fuses upstream of the power
supply adequate for the load and with a value of I ² t less than the value
given in the table below. If a differential circuit breaker is installed, it must be of the delayed action type. The
regulators with rated current > 16A are in accordance to the I C61000-3-12 on condition that the short circuit ratio
Rsce is greater than or equal to 120 at the interface between the user power supply and the public network. For
values Rsce minor can reduce harmonics by increasing the voltage/minimum speed.

To connect wiring to the spring terminals, apply leverage with a screwdriver on the lever or on the rectangular hole
to open the terminal (see below the panoramic view cards). The power wires of the VRTMS50 and 60 regulators
must be crimped to form an eyelet (M6 hole) and the nuts ( 10) tightened with a wrench.
LED WARNING SIGNALS
DL1 : yellow, starts to flash with input signal at
minimum and increases the flashing frequency as
the signal rises. It goes on steady with signal =
100%. It follows the priority signal (see Basic Sett.
[BS] in the Factory Parameters menu).
DL2 : green, steady ON = power supply ON.
DL3 : red, warning alarm ON:
1 flash = power phase lost.
2 flashes = external emergency.
3 flashes = internal over-temperature.
4 flashes = probe missing.
5 flashes = stop for parameters programming or
error settings.
DL4 : green, flashing in modbus transmission.

OPERATING PARAMETERS MENU - SLAVE
The operating parameters menus can be accessed from any visualization of the state menu, by pressing together
the keys + (hold the key pressed and press the key ).
The menu windows include the menu name and the corresponding [identifying
code].
The second line of the display is dotted.
•Press the key to enter the parameters of the visualized menu;
•Press the key to return to the state menu;
•Press the key to go to the next menu;
•Press the key to return to the previous menu.
PARAMETERS READING AND EDITING
The parameters windows display the name of the parameter, the [identifying code]
of the corresponding menu, the value of the parameter and the unit of measure.
• to go to the parameter below;
• to go to the parameter above.
To change the value of the parameter press , the arrow and the value of the
parameter in brackets mean that the system is in the parameter editing mode, edit
the value by pressing the following key :
• to increase the value
• to decrease the value
• to save.
• to return to the parameter;
