1. variety of process connections The process connection on the tank and its opening should be arranged so that the float can be inserted Should it not be possible the float should be removed from the sensor shaft After suggested opening inserting the shaft the float should be pulled onto the guide tube inside the vessel The word UP etched on the float is to ensure mounting the float in correct position To complete procedure the retaining pin should be inserted into its hole and legs bent Note before installation it is advisable to perform a preliminary operational check similar to the procedure described in the Calibration section 4 WIRING After unscrewing and removing the housing cover from the unit the cable should be pulled through the conduit opening The unit contains CMOS components which can be damaged by static electricity Therefore the shielding of the cable should be connected to the ground screw first After the shield is grounded the wire and wire of the terminal J1 should be connected Is the shield also grounded at the power supply an equaliser cable should be applied between the two ground screws liquid end positioner Terminal J1 gt ag 5 SETUP PROCEDURE CALIBRATION After power up the unit is fully operational Factory Setting Operation mode in accordance with the order normal or reverse Range maximum or in accordance with the order Damping 1s2.
