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.
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.
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.
.
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.
This will be the system operating pressure. Use keys
for modify the initial value (1 bar).
