Description of the relay outputs
36
Function
Contact
Action
LV1
Relay switches when the
limit value is exceeded at:
Limit value 1 or
measuring point 1
Volt-free
change-
over
contact
Programmable:
- Continuous contact
- Impulse (1-99 seconds/minutes)
- Interval (1-255 seconds/minutes)
- Two-step controller (only for one
measuring point)
- Hysteresis (limit value is exceeded
once, twice, three times)
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 (1-255 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. For controlling a feed pump for sampling
Please refer to the section entitled "Function AUX" for more details
and programming.
