Function Contact Action
LV2
Relay switches when the
limit value is exceeded at:
Limit value 2 or
measuring point 2
Volt-free
change-
over
contact Programmable:
- Continuous contact
- Impulse (1-99 seconds/minutes)
- Interval (1-99 seconds/minutes)
- Hysteresis (limit value is exceeded
once, twice, three times)
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

AUX (programmable function output)
The functioning of this volt-free relay output is programmable:
1. For reporting a current analysis and/or
2. For contact prior to an analysis, e.g. to operate with a
cooler or
3. Contact after an analysis
