Parameter
Description
Boost/Reverse Con-
Enables boost and/or reverse proce-
figuration
dures
Boost: at power-up the fan will go to
maximum speed and then go to the RPM
set by the controller. Can be used in fans
with Butterfly.
Reverse: when turned off, the fan de-
celerates to a stop, once stopped it will
begin to rotate with opposite direction of
rotation to the standard one so as to "at-
tract" the butterfly and facilitate closing.
Can be used in fans with Butterfly.
Allowable values: [0; 3]
0 - Boost and Reverse disabled
1 - Boost enabled,
Reverse disabled 2
* 2 - Boost disabled,
Reverse enabled
* 3 - Boost and Reverse both enabled
Default: 0
Reverse time
Time for the fan to rotate in the opposite
direction after reaching the speed setpoint
Unit of measurement: s
Allowable values: [0; 32767]
Default: 25
Reverse speed factor Fan speed setpoint during Reverse expres-
sed as a percentage of maximum rotational
speed
Units of measurement: %
Allowable values: [1; 100]
Default: 60
Boost ramp time
Acceleration time to reach the speed setpoint
during the boost phase
Unit of measurement: s
Allowable values: [12; 32767]
Default: 10
Boost maintain time Fan rotation time after reaching the speed
setpoint (Maximum speed)
Unit of measurement: s
Allowable values: [0; 32767]
Default: 5
Start delay
Delay in turning on the fan from the time it
receives the command from the control unit
Unit of measurement: s/10
Allowable values: [0; 100]
Default: 0
Saturn ONE
* with these parameters, once
the "Off" command is recei-
ved, the fan will automatically
begin to rotate in the opposite
direction for a predetermined
time.
Parameter
Description
Fallback speed
Rotation speed in case of loss of Modbus
communication. Active only if "Enable Live
Command (Reg.1009) = 1." In case the
Enable Live Command Reg. is = 0 and mo-
dbus is lost, the fan will continue to run at
the last operating speed before the loss of
communication
Unit of measurement: rpm
Allowable values: 0, [rpm min; rpm_max]
Default: 0
Slope change
The switch reverses the slope of the rela-
tionship between 0-10V voltage and rpm.
It allows reversing operation from: Low Vol-
tage, Low Speed and High Voltage, High
Speed => Low Voltage, High Speed and
High Voltage, Low Speed
Firmware upgrade
Through this tab, upon entering the password
(123456), firmware update of both microcontrollers
inside the inverter can be performed in case new fea-
tures or bug-fixing are available.
Before proceeding with the firmware update,
the configuration data must be backed up to
prevent loss. After the update operation is
completed, perform the reset.
The updating procedure consists of four different
steps:
•
the verification of the communication protocol to
be used for communication with the inverter;
•
the transfer of the firmware update file;
•
the safety stop of fan rotation;
•
Finally, writing the new firmware to the flash me-
mory of the inverter.
Completion of the various steps is denoted by a green
check mark.
Select the update file (*.upd), press the button to start
the procedure and wait for the outcome.
