CONFIGURATION. Using pq we can change the values and press ENTER for validation. Whenever we want to quit the
configuration sequence press MENU. After every ENTER it will appears automatically the different screens that constitute the configuration
sequence.

while the device is doing the autotest. Once it finishes, led light FAILURE is OFF and led light LINE is ON. The LCD screen will
show message "SPEEDBOX DUO " and inmediately the language display of the configuration mode.
The device is ready for being configured.

Using the keys ▲q we can modify the minimum frequency value.
*The minimum frequency value will be used as a stop frequency in those installations
where the automatic detection of stoppage of the device does not act due to leaks in the
installation. See hydraulic installation.
P 1
The default value is 0,5 bar. This value of pressure is the one that the system will
subtract to the input pressure, resulting the final pressure to which the system will set in
motion when the hydraulic network has a demand. Using keys pq to modify the initial
value. It is recommended
to maintain this value between 0,3 and 0,6 bar. Example:
P 2
- Input pressure: 2 bar.
- Differential start: 0,3 bar.
- Final start pressure: 2 - 0,3 = 1,7 bar.
The value should be greater as much as smaller be the accumulation and vice versa.
T I M E
The switching of the main pump (inverter) occur every cycle. In case of long periods of
operation, this value will switch the main pump after the time set.
Use keys pq to select the external input type:
NO: Disabled
LEVEL: Enabled as external level control.
ON/OFF: Closed contact -> System enabled / Opened contact -> System disabled
Second Pressure: Closed contact -> Principal pressure / Opened contact -> Second

Configuration of the minimum pressure in the system. With the value 0,0
bar, the control is disabled. If the system detects a pressure bellow the
"MIN.PRES" during a time longer than "t.P.Min" alarm A13 will appear.
Configuration of the time that the system can be working under the minimum
pressure before the minimum pressure alarm appears.
The range of lecture of the pressure transmitter installed must be adjusted.
If the range is within 0-10 bar confirm by mean of ENTER.
If the range is within 0-16 or 0-25 bar change it by mean of pq and then
confirm with ENTER.
