COSTRUZIONI MECCANICHE ELETTRICHEUse and maintenance manual for rotary level indicator series PFG05L & PFG57LPRODUCT IDENTIFICATIONThe PFG05L and PFG57L series instruments are rotary level indicators for granular solids. The identification of the device isaccomplished by the specific label outside the casing, whose characteristics are shown below:Tampering with the label entails the loss of validity of the product certifications.INSTALLATIONUse and maintenance manual for rotary level indicator series PFG05 & PFG57 0601_002_0_rev2 - 10.2022 Page 1 of 4The device can be installed in any position. In case of an horizontal or titledinstallation, mount the device with the cable entrance on the right side forPFG05L models, or lower side for PFG57L models. The coupling of theinstrument with the wall of the container (silos) can be either threaded oranged; images 2 and 3 show the standard couplings. Always refer to thetechnical drawings supplied by the Manufacturer together with this manual.Protect the device from falling material or excessive weight, using protectivedeectors. For cable entries, 1 (one) or 2 (two) G 1/2 threaded holes (BSPP) areavailable. Seal the cable entries with cable glands or sealing caps suitable forthe operating range shown on the label.The protective caps supplied with the device are only for protection duringtransport and storage, they are not suitable for the use of the instrument and it isresponsibility of the installer to replace them.The diameter of the power supply cable must correspond to the tightening range indicated by the cable gland used.1.
