ROV-300
Use
The controller is intended for the easy control of the rotation speed of a fan
or similar products. The controller must be placed in a junction box (box for
the installation of a circuit breaker).
Safety requirements
The controller must be installed by a qualified professional (electrician)
after carefully reading the product manual, and installation must conform to
safety standards.
CAUTION:
The controller’s contacts are under voltage. During installation, maintenance,
repair and setting, the controller must be disconnected from the main source
of voltage.
Contents of the package
The original packing contains:
- 1 controller
- User’s Manual
- Original packaging
Technical specifications
The ambient air must not contain explosive and corrosive particles.
Model| Voltage (V)| Frequency (Hz)| Maximum output power (W)| Degree of
protection| Weight (kg)| Dimensions (mm)| Maximum load (A)
---|---|---|---|---|---|---|---
ROV-300| 230| 50 / 60| 300| IP 40| 0.11| 95×85×60| 1.5
ROV-400| 400| 0.25| 78×78×63| 1.8
Before assembly
The controller must be installed on a vertical wall into a flush-mounted or external junction box indoors. To ensure safe installation and operation, it is necessary to prevent:
- penetration of water or rain drops
- access of direct sunlight
- placing the controller near heat sources and heating
The controller must be connected by means of connectors, the minimum distance between the contacts of which should be 3 mm, and using a terminal board. Connection must be made based on the diagram shown in
Assembly
Remove the frame from the controller body carefully.
Using a screwdriver carefully remove the decorative strips.
The following is necessary for connection:
- disconnect the supply of electrical current into all the wires
- insulate the ends of the wires in a length of 5 to 7 mm, then connect them to the right connectors and using a screwdriver tighten the safety screws of the connectors
- fix the controller securely into the junction box using the screws, and re-check the connection of all the supply cables to the connectors
- replace the decorative strips and frame
The setting of minimum speed is done using a screwdriver in a special opening on the rear side of the cover (see PIC. 2). After connecting to electrical current, turn the control knob clockwise to start the device. The rotation speed of the fan is decreased by turning the control knob in the clockwise direction, and it is accelerated by turning it counter-clockwise. The controller is equipped with a replaceable fuse to protect against overvoltage. The recommended minimum rotation speed of a fan is no less than half the maximum speed.
Storage conditions
The product must be transported and stored in the original packaging in a dry,
well-ventilated environment at temperatures from +5 °C to +40 °C and a maximum
relative humidity of 80% (at a temperature of +25 °C).
ROV-400
Use
The ROV-400 thyristor speed controller (referred to as the “controller” below)
is intended for the continuous control of the speed of rotation of a fan with
a maximum power of 400 W. If you turn the controller to the right (clockwise),
you will reach the highest speed of the fan; if you turn it to the left
(counter-clockwise), you will gradually decrease the fan’s speed until the
position where you will switch the fan off by a click.
Safety requirements
The controller must be installed by a qualified professional (electrician)
after carefully reading the product manual, and installation must conform to
safety standards.
CAUTION:
The controller’s contacts are under voltage. During installation, maintenance,
repair and setting, the controller must be disconnected from the main source
of voltage.

ROV-400| 400| 0.25| 78×78×63| 1.8
Assembly
The controller must be placed inside a room vertically on a wall, preferably
in a flush-mounted junction box. Connection to the electric network should be
made via an automatic switch (circuit breaker).
Procedure for assembly and connection of the controller:
- remove the control knob (1)
- unscrew the nut (2) from the top cover and take off the cover (3)
- unscrew the screws (4) and remove the controller (5)
- pull the supply cables through into the junction box (6)
- install the junction box into the wall
- insulate the ends of the supply cables at a length of 6–7 mm
- connect the supply cables into the terminal block located in the controller according to the diagram .
- place the controller into the junction box in such a way that the terminal block is located in the upper part of the controller and fix the screws.
After assembly
To ensure that the fan operates normally, it is necessary to control its minimum speed of rotation.
Proceed as follows:
- turn the control knob in the counter-clockwise direction to the extreme position without switching the controller off
- switch on power supply
- turn the potentiometer screw by means of an insulated screwdriver (see PIC. 2) until the speed of rotation is minimal
- turn the control knob to the off position (in the counter-clockwise direction until it “clicks”), wait until the fan stops
- switch the controller to the minimal speed again, the speed of rotation is set to the minimum.
CAUTION:
It is prohibited to control the fan by means of the controller if the minimum
speed is not set correctly! Damage to the fan may result.
- Fix the controller cover and secure it with a nut.
- Replace the control knob.
Possible faults and their elimination
The controller should start working immediately after being connected to the source of voltage. If the unit does not start working at once, check it for possible problems according to the table.
| Fault | Possible cause | Elimination |
|---|---|---|
| The unit is not working. | No or limited connection. | Check the correct |
connection to power supply. (see Assembly)
Ruptured fuse.| Replace the fuse.
The controller is on, the fan is not working.| The minimum rotation speed has
not been set correctly.| Reset the minimum rotation speed.
Storage conditions
The product must be transported and stored in the original packaging in a dry,
well-ventilated environment at temperatures from +5 °C to +40 °C and a maximum
relative humidity of 80% (at a temperature of +25 °C).
