Page 10: Indicator Part
Indicator part Contact inserts The flowmeter SDA can be equipped with a maximum of two electronic limit switches. The limit switch functions with a slot-type initiator which is operated inductively through the semicircular metal vane belonging to the measuring pointer. The switching points are set through the contact pointer. - Page 11 Connection diagram 2-wire technology NAMUR Safety-oriented * SC3,5-N0-Y SJ3,5-SN and SJ3,5-S1N Inputs Input Terminals Terminal in the in the display display Output I Output II Power Output III Output I Power LED yellow output LED green power LED yellow Relay output Switch S1 LED red LB/LK Effective direction I...

Page 16: Maintenance
Maintenance The flowmeter is also to be inspected for soiling, corrosive erosion and mechanical wear or damage to the measuring tube and the display in the context of the routine operational maintenance of the installation and the pipelines. We recommend at least annual inspections. In order to clean the instrument remove it from the pipeline. Note Pressurized lines have to be relieved before the measuring unit is removed. -
