RPL75 - installation 5.1.3 Blind distance During installation is important to remember that in the sensor proximity there is a blind zone (or BLIND DISTANCE) of 0.05m where the sensor can not measure. 0.05 Min. Blind Distance 5.1.4 Installation in nozzle In case of nozzle installation, make sure the sensor bottom protrudes at least 10mm from the bottom of the nozzle.

The level measurement is possible thanks to the Auto-Tuned statistical fi lter. Should rarely need to adjust the fi lter setting by editing 2 RPL75 sensor programming parameters: - FILTER; this parameter is present in the Quick Setup menu and in the Advanced Confi guration “SETUP” menu;...
RPL75 - electrical connections 6-ELECTRICAL CONNECTIONS 6.1 WIRING 1) Separate the engine control cables or power cables from the RPL75 connection cables. 2) Open the cap by unscrewing. 3) Lead the cables into the transmitter through the glands. 4) Do not use sleeves terminals, because they might interfere with the VL601 module insertion.
3) MODBUS RTU communication S/W, cod.010F105A, for RPL75 transmitter. With this so! ware is possible: - to connect the RPL75 transmitters in MODBUS RTU network by selecting the UID address. - to read on your PC monitor all measures in reading and RPL75 operation data.
