Limit value 2 or
measuring point 2
Please refer to the section entitled "Switch functions of the limit value
outputs LV1 und LV2" for more details and programming!
Measuring points 1 or 2 (measuring point switch-
over)
If the instrument is used for monitoring two measuring points, the
solenoid valves (individual valves or one 3/2-way control valve) of the
corresponding sampling line have to be connected to this output. The
terminals are strictly allocated to the measuring points.
Terminal 9 = Measuring point 1 , Terminal 10 = Measuring point 2
