2. GENERAL INFORMATION
2.1 Cable for connection to the electrical supply
The cable for connection between the frequency inverter and the fan terminal box must be shielded, with a recommended maximum length of 50m.
IMPORTANT: The metal mesh of the shielded cable must be earthed in the fan terminal box.
If the fan is installed with a cable and an external terminal box, and the motor has its own terminal box connect the inverter shielded cable directly to the motor terminal box, removing the cable and the remote terminal box.
2.2 Inverter reconfiguration
Frequency inverters are pre-programmed to be used via proportional control with a built-in potentiometer (FR2 with jumper between 24V and LI3) or via PI control with a 0-10V voltage input (FR1 with jumper between 24V and LI1).
For other uses, some of the parameters configured in the frequency inverter must be re-programmed. To do so, use the following inverter commands:
text_image
= ENT -↓+ESCStep 1. Unlock the inverter
To unlock the inverter, enter the password. The sequence is as follows:
- Press ESC until "rdy" appears on the screen.
- Press ENTER and rotate the wheel anti-clockwise until "SUP-" appears on the screen.
- Press ENTER and rotate the wheel clockwise until "COd-" appears on the screen.
- Press ENTER and rotate the wheel clockwise until "1951-" appears on the screen.
- The entered code flashes. At this time the inverter is unprotected.
Step 2. Enter programming mode
The inverter has 2 operating MODES, RUN and PROGRAMMING. To switch from one to the other keep ESC pressed for two seconds.
Location of the 3 Mode Leds.
Depending on how they are lit up, they indicate the selected mode:
- IN SEQUENCE→ RUN MODE
- SIMULTANEOUSLY→ PROGRAMMING MODE
text_image
REF MON ONF rdy RUN CAN ERR- Keep ESC pressed down for 2 seconds until the 3 mode leds light up simultaneously. At that moment they are in Programming Mode.
Enter the parameters depending on the required use.
2.3 Manual reset – Automatic reset
The frequency inverters are delivered pre-programmed for automatic reset.
This means that in the event of a power cut, the fan will automatically switch on when the power returns.
IMPORTANT RISK OF ELECTROCUTION RISK OF SERIOUS INJURY
When is enable the thermal protection motor should review the need to use the manual restart function.
With the factory settings (automatic restart), once skipped the motor thermal protection, when is produced the motor cooling, it re-start automatically.
See section 2.3. to modify the automatic restart to manual restart.
If the motor connected to the inverter has thermal protection, the inverter must be re-programmed for manual reset.
IMPORTANT: If the thermal protection is activated it is necessary to wire the motor TP connections to the corresponding terminals of the inverter in order to achieve electrical protection.
- Keep ESC pressed down for 2 seconds until the 3 mode leds light up simultaneously. At the moment the inverter is in Programming Mode.
- Press ENTER and rotate the wheel until "FLt-" appears on the screen.
- Press ENTER and rotate the wheel until "Atr" appears on the screen.
- Press ENTER and rotate the wheel until "NO" appears.
- Press ENTER to confirm the value entered. If this value is different to the previous one, the display should flash.
- Press ESC to exit the "Atr" parameter.
- Press ESC to exit the "FLt-" menu.
- Keep ESC pressed down for 2 seconds until the 3 mode leds light up in sequence. It is now in RUN mode, available for automatic inverter operation.
Check that the "SW1" switch is in the "SOURCE" position
Install the indicated jumpers in the inverter terminal box.
Power the frequency inverter with suitable voltage for the inverter model in question.
2.4 Changing the minimum/ maximum speed
Frequency inverters are delivered pre-programmed with a minimum speed setting at 20 Hz.
Warning! The continued power supply of a motor at frequencies below 20 Hz can cause motor overheating and premature failure. Motors that have been working below 20 Hz will not be covered by warranty.
However, in overpressure applications stairs or escape routes, it is possible that in the situation of closed doors reduce the minimum speed of inverter to avoid exceeding the overpressure value established by the relevant regulations. This requires checking out the inverter and access to the programmation mode (steps 1 and 2 in section 2.2) and then perform the following configuration changes:
- Press ENTER and rotate the wheel anti-clockwise until "SEt-" appears on the screen.
- Press ENTER and rotate the wheel anti-clockwise until "LSP" appears on the screen.
- Press ENTER and rotate the wheel until the necessary value appears for the "Minimum frequency in Hz" parameter. Press ENTER to confirm the value entered. If this value is different to the previous one, the display should flash.
- Press ESC to exit the "LSP" parameter.
- Press ESC to exit the "Set-" menu.
In the same way, the "HSP" maximum frequency value must never be set above the frequency value for the mains power supply in the country where it is used.
2.5 Preparing the motor thermal protection
To enable the motor thermal protection, so that a motor overheating condition causes the inverter to stop, it is necessary to reprogram some of the parameters that are configured in the frequency inverter. This requires checking out the inverter to access to the program parameters (steps 1 and 2 in section 2.2) and perform the following configuration changes:
- Press ENTER and rotate the wheel until "FLt-" appears on the screen.
- Press ENTER and rotate the wheel until "Etf" appears on the screen.
- Press ENTER and rotate the Wheel until "L15" appears on the screen. Press ENTER to confirm the value entered. If this value is different to the previous one, the display should flash.
- Press ESC to exit the "Etf" parameter.
- Rotate the wheel until appears "LEt" on the screen.
- Press ENTER and rotate the wheel until appears "LO" on the screen. Press ENTER to confirm the value entered.
- Press ESC to exit the "LEt" parameter.
- Press ESC to "FLt" parameter.
- Keep ESC pressed down for 2 seconds until the 3 mode leds light up in sequence. It is now in RUN mode, available for automatic inverter operation.

RISK OF ELECTROCUTION
RISK OF SERIOUS INJURY
When is enable the thermal protection motor should review the need to use the manual restart function. With the factory settings (automatic restart), once skipped the motor thermal protection, when is produced the motor cooling, it re-start automatically.
See section 2.3. to modify the automatic restart to manual restart.
2.6 To achieve theStart/stop function with an external switch
This function is common to all systems where the inverter works with external sensors (pressure, airflow, CO2, temperature, humidity, etc.)
it is also possible to achieve the remote control function (start/stop) by means of an external switch with volt-free contacts.
For this it is necessary to use the corresponding switching diagram, replacing the existing a jumper between LI1 and 24 V for wiring to the external switch.

4.3 PI CONTROL IN CONSTANT PRESSURE / AIRVOLUME SYSTEMS WITH AN EXTERNAL ANALOGUE SENSOR AND 0-10V SENSOR
4.3.1 Features
Constant Air Volume (CAV)
The inverter is used to guarantee a specific air volume in a duct system, regardless of filters closing.
Constant Pressure (COP)
The inverter is used in variable airvolume systems to guarantee specific air pressure in the duct system, regardless of whether the dampers are open or closed. In both cases, the pressure must be constant in the duct system. The value of this pressure must be determined by experimenting during the system start-up process.
A TDP-D differential pressure sensor with display is necessary to start up this system.
The first attempt at making the adjustment will be by changing the sensor range. The established pressure values are:
| Value entered “rPI” | Pressure to be maintained in duct system (Pa) |
| 0-100 | 50 |
| 0-150 | 75 |
| 0-300 | 150 |
| 0-500 | 250 |
| 0-1000 | 500 |
If none of the values in the table above is suitable for the installation, you must establish the exact pressure setting by re-configuring the frequency inverter. (see point 7.3.)

Install the indicated jumpers in the inverter terminal box.
Power the frequency inverter with suitable voltage for the inverter model in question.
The frequency inverter will start automatically when it receives power and will perform PI controller functions
