Figure 4: Hydraulic installation
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.
2.2.3 Connection of sensors
The terminations for sensor connections are on centre section and are accessible by removing the plastic
cover fixed with four screws in the corners. The sensors must be connected to the relative inputs marked
"Press" and "Flow"; see Figure 5.
