(see design above). Direct SITRANS LR460 so the horn antenna is pointed at an angle perpendicular to the material surface, if possible. (As a guide, aim the beam at a point approximately 2/3 of the way across the tank diameter.) When the desired position is reached, re-tighten the 5 bolts to 15-23 N m (11 to 17 Lbf-ft).

Adjust the cable length so that the earth (ground) earth conductor would be last to disconnect if cable terminal is pulled. Tighten the cable gland and check the strain relief (pull and turn). 7ML19985QW82 SITRANS LR460 – QUICK START MANUAL Page EN-7...
Note: Power Demands To determine how many devices can be connected to a bus line, calculate the combined maximum current consumption of all the connected devices: 10.5 mA for SITRANS LR460. Allow a current reserve for safety. Bus Termination PROFIBUS PA MUST be terminated at both extreme ends of the cable for it to work properly.

In order to save the Quick Start settings it is necessary to enable Apply Changes. YES, NO Options Select YES. SITRANS LR460 is now ready to operate and returns to RUN mode. Communication via HART or PROFIBUS PA Notes: • The Quick Start settings are not independent parameters. The settings are inter- related, and changes only apply when you click Transfer at the end of step 4.
