Soler Palau MELLIZO Twin Fan Instruction Manual

Soler Palau MELLIZO Twin Fan

Product Information

The MELLIZO twin fan is a product designed by Soler & Palau. It consists of two inline centrifugal fans housed in an acoustically lined cabinet. Each fan operates independently and can be used for run and standby functions. The unit also has a duty-share function that can be set for 3 to 24 hours, with the display indicating the status of the unit.

Speed Control Inputs

• Variable Speed Control : Allows manual variable speed control using an optional secondary S&P REB ECOWATT or REB-CVF controller.
• Automated variable speed control : Can be achieved by providing a 0-10V signal from an external source.

Installer-defined Fixed Speed Control
The Mellizo twin fan offers the option for installer-defined fixed speed control.

This can be set as

• Continuous duty or on-demand duty triggered by an external switch.
• One, two, or three speeds defined during installation to provide a minimum/middle/maximum speed ventilation system. The middle and maximum speeds can be selected using an external switch/sensor (either Volt-free and/or 230V).

Note: The fan requires a minimum output of 3 Volts to ensure start-up momentum.

GENERAL

The Mellizo range comprises of two inline centrifugal fans in an acoustically lined cabinet; each fan works independently for run and standby plus 3 to 24 hours duty-share function with the display indicating the status of the unit.

Speed Control Inputs

• Variable Speed Control
• Manual variable speed control via an optional secondary S&P REB ECOWATT or REB-CVF controller, or
• Automated variable speed control via a 0-10V signal from an external source.

Installer-defined Fixed Speed Control

• An upon-installation defined duty either continuous or on-demand (triggered by an external switch), or
• One, two or three speeds defined during installation to provide a minimum/middle/maximum speed ventilation system, the middle and maximum speeds being selected by an external switch/sensor (either Volt-free and/or 230V).
• Note that there is a 3-Volt minimum output to the fan to ensure start-up momentum.

Remote Switching

• The switching between the (up to) three speeds can be activated by either
• (Up to) Three Volt-free contacts, or
• (Up to) Three 230V supply inputs
• On/Off – Volt-Free Contact and/or 230V
• External Fire Fan Shut-Off Switch – An external “Fire” switch (Volt-Free) can be connected, If the switch opens signifying that the fire alarm has been activated, then the MULTI-REG Controller will automatically stop the fan.

Fan-Fail Detection by Fault Sensing

• Automatic monitoring of the impeller rotation via the Tacho pulse (frequency generator) signal.
• Low current sensing to indicate a connection open circuit problem.
• Sixty seconds time-delay of fault detection on start-up to allow input levels to normalise.
• Facility to connect an Airflow Switch or Differential Pressure Switch (DPS), for use on fans where other options are not practical. There is approximately a 60 seconds delay in the operation of the airflow switch monitoring system, to allow full airflow to develop.

Outputs

• Digital Display
• Running, Stopped and/or fault condition.
• Fan speed percentage and 0-10V output condition.
• Countdown to fault status monitoring condition (allows fan to gain speed).
• Diagnostic – Reasons for fan stop/fail.

Analog Switch Outputs
Output to BMS of fan run and fault indicated by an individual set of contacts capable of controlling a maximum load of up to 230 Volts at 8 Amps.

TRANSPORT AND HANDLING

• The equipment packaging has been designed to withstand normal transport conditions. The equipment must not be transported without its original packaging as it could become damaged.
• The product must be stored in its original packaging and in a dry and clean place until it is installed. Do not accept any equipment that is not supplied in its original packaging or that shows signs of having been tampered with.
• Prevent the packaging from falling or being knocked
• Do not place heavy loads on top of it.
• When handling heavy products, adequate lifting equipment techniques and equipment should be used to avoid injury.
• Do not lift a product by pulling the wires, terminal/control enclosure, shutter or impeller to avoid damaging the product.

SAFETY RULES

ON INSTALLATION

• Installation and commissioning must be done by a qualified professional specialist.
• Ensure that installation complies with mechanical and electrical regulations in each country.
• Once commissioned, the equipment must comply with the following Directives
  • Standard for Low Pressure Instalments 2006/95/CE
  • Machinery Standard 2006/42/CE
  • Standard for Electromagnetic Compatibility 2004/108/CE
  • Do not use this equipment in explosive or corrosive atmospheres.

AT START UP

• Make sure there are no loose elements near the ventilator, as they could run the risk of being sucked up by it. If it is going to be installed in a duct, check that it is clean of any element that could be sucked up by the ventilator.
• When installing an apparatus, make sure that all the fittings are in place and that the structure which supports it is resistant enough to bear its weight at full functioning power.
• Before you handle this equipment, ensure it is disconnected from the mains power supply.
• Check that the mains voltage and frequency are the same as specified on the name plate.
• Follow the wiring diagram to make the electrical connections.
• Check that the earthing, if any, is correct and that the thermal and surge protection has been connected and are within the relevant limits.
• If a ventilator is installed in a duct, the duct must be exclusively for the ventilation system.

MECHANICAL INSTALLATION

The product should only have the airflow going vertically up and horizontally. In this orientation it is suitable for fitment onto a suitable supportive structure and secured through the 4 fixing holes provided.

• Leave an air space of not less than 150mm around the edges control enclosure to allow cooling air to flow freely.
• Leave an additional gap in front of the control enclosure lid to allow for access during installation/wiring/maintenance.
• Do not install in close proximity to other heat sources.
• The maximum ambient temperature for the control board must not exceed 40°C.

The 2 fans integrated into the product are separately wired into a MELLIZO control panel located in an enclosure box positioned on the external casing.

TIMER FUNCTION

Timer function
The over-run timer works when you alter the ‘Timer’ potentiometer, this will allow you to add an over-run of 0 to 15 minutes; the over-run function will operate for both remote enable and boost functions.
If a 10-minute over-run is set then the remote enable will over-run for 10 minutes and the boost will over-run for 10 minutes.

MAINTAINENCE

• Before manipulate the device, make sure that it is disconnected from the mains and that no one can turn it on during the intervention.
• The apparatus must be regularly inspected. These inspections should be carried out bearing in mind the ventilator’s working conditions, in order to avoid dirt or dust accumulating on the impeller, motor or back-draught shutter. This could be dangerous and perceptibly shorten the working life of the ventilator unit.
• While cleaning, great care should be taken not to unbalance the impeller or motor.
  In all maintenance and repair work, the safety regulations in force in each country must be observed.
