The display indicates fan status (running, stopped, fault), speed percentage, 0-10V output condition, and a countdown during fault detection start-up delay.
How does the duty-share function work?
The fans alternate between run and standby modes with a duty-share period of 3 to 24 hours, balancing usage and extending lifespan.
How do I connect remote switches?
Use volt-free contacts or 230V inputs for remote enable, speed selection, or fire shut-off. Refer to wiring diagrams for specific configurations (e.g., 3-set speeds, prep/cook switch).
What triggers a fault indication?
Faults are triggered by impeller rotation failure (Tacho pulse), open circuit (low current), or external airflow switch. The display shows "EXTERNAL SW1 FAULT" or "FIRE ALARM ACTIVATED".
How do I clean or maintain the fan?
Disconnect power before maintenance. Regularly inspect and clean the impeller, motor, and back-draught shutter. Avoid unbalancing the impeller. Follow local safety regulations.
What are the electrical requirements?
The fan requires 230V AC, 50Hz supply. Check the nameplate for exact specifications. Ensure proper earthing and surge protection.
What is the warranty period?
S&P offers a 24-month warranty from the original purchase date against defective materials and workmanship, provided installation follows instructions and standards.

1. RECOMMENDATIONS

You have purchased a MELLIZO twin fan designed specifically by Soler & Palau to perform the functions described in the table of contents.

Before you install and start up this product, please read this instruction book carefully because it contains important information for your safety and the safety of users during installation, use and maintenance. Once installation is complete, please pass the instruction book on to the end user. Please check that the equipment is in perfect condition when you unpack it since any factory defect is covered under the S&P guarantee. Please also check that the equipment is the one that you have ordered and that the information on the instruction plate meets your requirements.

2. 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.

2.1. 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.

2.2. 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.

2.3. 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.

2.4. 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.

2.5. 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.

2.6. 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.

3. TRANSPORT AND HANDLING

External fault (SW1)

When the fan is in normal running conditions the switch should be in the closed position. If additional switches are required then can be connected in series. During start-up there is a 60 seconds delay to allow the airflow to increase. When the fault switch opens signifying loss of airflow, the controller will automatically stop the fan and display "EXTERNAL SW1 FAULT".

Following an "EXTERNAL SW1 FAULT", a manual re-start will be required.

Fire shut-off (SW2)

When the fan is in normal running conditions the switch should be in the closed position. When the fault switch opens signifying the fire alarm has been activated, the controller will automatically stop the fan and display "FIRE ALARM ACTIVATED".

Following an "FIRE ALARM ACTIVATED", a manual re-start will be required

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.

8. 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.
