parameter
To ensure proper operation of pressure control is recommended to place the sensor near the pump.
To compensate the pressure loss in the pipes (proportional to flow) it is possible to vary the pressure set in a linear relation
with respect to frequency.
H
It can perform the following test to verify the correct value of compensation:
1. install a pressure gauge away from the pressure sensor
2. open completely the valve
3. check the pressure gauge
--> Set the value of compensation. equal to the difference of the values from the two gauges.
When using a group of pumps, the pressure compensation to be applied to each pump is equal to the total pressure
compensation (when all the pumps are running at full speed) divided by the number of pumps in the group.
