want to quit the configuration sequence press MENU. After every ENTER it will appears automatically the
different screens that constitute the configuration sequence.

This will be the system operating pressure. Use keys
value (1 bar). WARNING ! The input pressure must be al least 1 bar lower than the
.
maximum pressure of the pumps.
By mean of keys pq input the nominal intensity value in A of pump 1 enabling the
thermal protection. This value is located over the characteristics plate of the
motor. Press ENTER for validation.
Proceed identically for pump 2.
Using START/STOP pushbuttons are successively verified the rotation senses of
both pumps when they are connected through the inverter. By mean of key p
(0/1) we can change the sense. If the recommendations in Fig. 4 have been
followed, both pumps must rotate in the same direction, otherwise, the
connection of one of the pumps will be reversed, either in the pump´s terminal box
or in the Speedbox
Using the START/STOP pushbuttons, check the direction of rotation of the
pumps when they are connected through the relay. If the direction of rotation is
not correct, the order of the Speedbox power cables will be reversed.
Press ENTER for validation.
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.
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:
- 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.
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 pressure enabled
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.
