2.2.2 Hydraulic
connections
The inverter is connected to the hydraulic section by means of pressure and flow sensors. The pressure
sensor is always required, while the flow sensor is optional if operating in stand alone mode, and is
compulsory when creating multi inverter systems.
Both are mounted on pump delivery and connected by means of the relative cables to the respective inputs
on the inverter board.
Always fit a check valve on pump suction and an expansion vessel on pump delivery.
In all circuits subject to the risk of water hammer (for example irrigation systems with flow rate interrupted
suddenly by solenoid valves), fit a further check valve downline of the pump and mount the sensors and
expansion vessel between the pump and valve.
The hydraulic connection between the pump and sensors must not have branched sections.
Pipelines must be sized according to the type of electric pump installed.
Excessively deformable systems may generate oscillations; if this occurs, the user may solve the problem by
adjusting control parameters “GP” and “GI” (see sections
6.6.4
and
6.6.5
)
NOTE: The inverter makes the system work at constant pressure. This setting is best exploited if the
hydraulic system downline of the system is suitably sized. Systems with excessively small pipelines
can cause pressure drops for which the equipment is unable to compensate; the result is constant
pressure on the sensors but not on the utility.
