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)
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
Risk of foreign bodies in pipelines: the presence of dirt in the fluid may obstruct transfer channels,
block the flow or pressure sensor and impair correct system operation. Take care to install the sensors so
that they are not subject to the build-up of excessive sediment or air bubbles that may impair operation. If the
size of the pipeline enables transit of foreign bodies, a special filter may need to be installed.
