Operating mode range
The relays switch when the predefined range between LV1 to LV2 is
exited:
•
If GW1 is not attained, relay 1 switches
•
If GW2 is exceeded, relay 2 switches

Switching function only after multiple exceeding of limit value
The respective limit value output can be set to be triggered after the
first, second or third exceeding of the limit value.
This improves the assessment of the analysis e.g. after possibly in-
sufficient purging of the sampling line.
The value may be separately configured for both the LV1 relay and
LV2.
The basic setting is 1 for LV1 and LV2. Switching occurs immediately
after the limit value is exceeded, with no delay.
When the number of times the limit value has been exceeded is "2",
the next analysis is performed immediately after the first exceeding of
the limit value. Only after the limit value has been exceeded twice is
the corresponding output switched.
When the limit value has been exceeded "3" times, the corresponding
output only switches after the limit value has been exceeded three
times consecutively. This setting is only reactivated once the reading
falls under the limit value!
Switching function duration
If the limit value LV1 or LV2 is exceeded, the output LV1 relay or LV2
switches. If the limit value LV1 or LV2 is not attained, the correspond-
ing relay is again deactivated.
Switching function impulse
If the LV1 or LV2 limit value is exceeded, the corresponding output
switches for the set time (t).
Regardless of the duration for which the limit value is exceeded, the
corresponding output remains always switched for the set time. A
renewed impulse is possible only once the reading falls under the
limit value!
