Hold MENU 3 seconds. By mean of keys ↑↓ we can choose
the languages: "LANGUAGE ENGLISH", "LANGUE FRANÇAISE",
"LINGUA ITALIANA" and "IDIOMA ESPAÑOL".
This will be the system operating pressure. Use keys ↑↓ for modify the
initial 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 ↑↓ input the nominal intensity value in A of pump 1
enabling the thermal protection. This value is located over the characte-
ristics plate of the motor. Press ENTER for validation.
By mean of keys ↑↓ input the nominal intensity value in A of pump 2
enabling the thermal protection. This value is located over the characte-
ristics plate of the motor. Press ENTER for validation.
Using the ↑ pushbutton verify the rotation sense of pump 1. By mean of
key ↑ (0/1) we can change it. Press ENTER for validation.
Using the ↑ pushbutton verify the rotation sense of pump 2. By mean of
key ↑ (0/1) we can change it. Press ENTER for validation.
Using the keys ↑↓ 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 ↑↓ 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 ↑↓ 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 SET POINT: Closed contact -> Principal pressure / Opened con-
tact -> Second pressure enabled
When Second Pressure is selected, the system can work in two different
pressures depending on the contact (opened or closed). The principal
pressure is configured as SET POINT and the second pressure is configu-
red as SET POINT 2.
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.PRESS ALARM during a time longer than TIME MIN. PRESS. alarm
A13 will appear.
