SAFETY RULES !

This appliance has been designed to give excellent performance provided it is installed and used carefully in a suitable electric environment by qualified personnel. The following rules

Follow the instructions in this manual exactly and observe all safety measures in force.

•

Do NOT tamper with or disassemble the regulator's internal components; doing so will

•

INVALIDATE THE GUARANTEE and may cause unnecessary damage. The regulator does not contain components that can be repaired by the user.

•

The regulator must be suitably and effectively earthed by the installer according to the standards in force; earthing is essential for the EMC filt er to oper ate cor re ctly .

•

The user must be protected from the electric supply and the motor must be protected from possible overloads in compliance with the standards in force.

circumstances.

•

Before supplying power to the unit, check carefully that the power and earth are correctly connected.

•

If the mains supply is "disturbed", which may be due to other electrical power components causing irregularities in the supply (power contactors), it is recommended that supplementary three phase

SURGE ARRESTER

‘

•

Avoid repeatedly connecting and disconnecting the power supply to the regulator; a constant supply keeps the regulator at working temperature and eliminates problems caused by condensate inside the protection case.

•

Alternatively, use the remote terminal board contact 'MB' S2 = ON/OFF.

•

The S2 = ON/OFF contact on the MB terminal board does not cut the mains supply and therefore cannot be used as a safety switch.

•

Install the regulator out of direct sunlight so that the container cannot get overheated and cause a reduction in the maximum load current.

•

The appliance may operate at environmental temperatures up to 50°C. Do not install it where this temperature may be exceeded or the integrity of the regulator will be compromised and the appliance may make the user appliance operate at full load (100%) with all consequent effects.

•

The appliance must be stood vertically to encourage heat dissipation and to ensure there is a sufficient air circulation and free space measuring be grouped together on a single electric board, provide forced air circulation with a fan or cooling unit of sufficient power.

•

Use the holes on the lower and power terminal board sides of the appliance, for entrance of the connection cables. This will prevent water, dust etc. from getting in and will ensure the level is maintained using adequately sized cables and sheaths of suitable quality.

Reassemble and check the cover of the external protection panel is properly closed.

•

DO NOT alter or damage the identification stickers on the equipment.

•

DO NOT force the trimmers to rotate beyond their set mechanical travel.

•

Only alter the trimmers intended for regulation.

•

Under no circumstances alter the trimmers marked with the spot of red paint.

1.3 PRINCIPLE OF OPERATION

rgf300

The

series appliances are voltage regulators that use the phase cutting principle totally controlled over three phases. The regulators, also referred to as speed controls, have been designed to change the average voltage on the following types of equipment, according to a control signal:

•

asynchronous three phase motors connected to

•

electrical resistor device s with sec tio ned

fans, pumps, agitators, mixers

single / three phase

.

;

Regulation occurs as a result of cutting of the input sinusoid. Regulation does not generate any torque knock or pulsation and is particularly quiet. Any voltage loss is contained within a maximum limit of 1%.

power devices

The speed regulators are sized to withstand a starting current equal to more than twice the rated current; therefore, when choosing a regulator, it is essential to take into consideration both the motor starting current and the type of motor. It is actually well-known that, while the starting current in axial fans is equal to 2 or 3 times the rated current, the same current in centrifugal fans can have values around 7 or 8 times the rated current. As far as the choice of motor is concerned, it is advisable to choose motors suited to the type of regulation. As a general rule, the best suited are:

motors with high slipping resistive motors

•

defluxed motors

•

tropicalised motors

•

CLASS H motors

•

as these allow better performance to be obtained with speed changes, they are quieter and start with lower current.

When choosing a motor, it is always advisable to contact your own supplier and order a motor which is suitable for speed control by voltage change. Subsequently, practical trials should be carried out on the motors or prototype machines in order to check their correct operation.

After choosing the motor, the speed regulator must be ordered according to

1.4 ELECTRIC MOTORS

Three phase asynchronous motors can be connected to the

rgf300

regulator in applications where the torquemotor speed characteristic is quadratic. This mainly allows phase cutting application with axial and centrifugal fans used for control purposes. The correct electrical connection and the supply voltage are given on the motor's specifications plate. The sense of rotation of the motor can be altered by swapping the connections of two of the three supply cables. It is important to keep the motor power supply cable as short as possible to reduce the level of interference and leakage currents to a minimum

(10 / 15 mt)

; if the cable has to be long, an auxiliary three-phase filter of exactly the same power as the regulator must be installed on the regulator output. The figure below shows the star and delta connection configurations.

's specification plate. The speeds of the motors vary at the same time though any differences in behaviour during start up and at low speeds are due to slight differences between the motors even if they are of the same type. However, if the required speeds of the motors are different, motors must be used with different rated speeds. Bear in mind though that motors with very different characteristics create different electrical situations and these may cause problems on start up and at low speeds caused by different resistances of the stators which require different voltages on start up and at low speeds.

1.4.1 Magnetothermal protection

rgf300 Installation of magnetothermal protections is the responsibility of the installer

devices must be protected by a magnetothermal switch fitted upstream of the cutting regulators.

2.0 ELECTRICAL CONNECTIONS

2.1 POWER CARD ELECTRICAL CONNECTIONS

For supply and load connection, reference should be made to the diagrams shown in section of the cables is adequate to the connected load . The power cables (supply and load) must be installed separately from the control cables (analogue inputs and ON-OFF inputs/outputs) keeping the maximum distance possible between the conductors.

Do not place power cables with signal cables in the same raceway. If the cables cross one another, ensure it is at 90°.

ATTENTION : connect the earth conductor to the screw placed purposely beside the dissipator. Use heat resistant cables able to withstand temperatures greater than 90°C.

).

When connecting the by-pass, the following precautions should be taken into consideration: i) connection made through the by-pass switch must keep phase correspondence unaltered so as to

avoid destructive shortcircuits and maintain the motor's sense of rotation. ii) before supplying the load with maximum voltage, supply to the regulator should be disconnected, therefore:

it is advisable to use a three-position manual switch as a commutation device

if automatic commutation is carried out by means of contactors, make sure there is some delay (at

when the external control unit uses a voltage control signal (

This configuration allows a grid of several regulators to be controlled via a single regulation control signal in either mA or Vdc, even if the regulators are a mixture of single phase and three phase. It is therefore possible to control totally and automatically several ventilation units and, if necessary, to release one or more regulators from automatic regulation that, using a local manual control signal (only with

0-10 Vdc

control), are regulated to the requested voltage.

WARNING !

• Check the position of jumpers 'Jn' during commissioning.

If the rgf300regulator work mode is altered (MASTER / SLAVE), refer to fig.s 19, 20, 21, 22 and 23 which give the standard work configurations of the jumpers.

• The regulator is already set for the operations indicated on the label on the side of the casing; if modifications

are required, describe and indicate the modifications made on the TECHNICAL ASSISTANCE MODULE.

WARNING !

• The configuration with NTC temperature sensors is not compatible with other configurations.

It is not therefore possible to alter the position of the jumpers to pass from operation with NTC sensors to operation with active sensors or control signals in mA or Vdc, nor to change the °C work field/scale of the rgf regulator.
