Behavior of the alarm outputs
17.12.1 Apparent switching delay
The measured values and totalizer values will be displayed rounded to 2 decimal places.
The limits, however, will be compared to the non-rounded measured values. This might
cause an apparent switching delay when the measured value changes marginally (less
than 2 decimal places). In this case the switching accuracy of the output is higher than
the accuracy of the display.
17.12.2 Reset and initialization of the alarms
After an initialization of the transmitter, all alarm outputs will be configured as follows:
Press 3 times key C during the measurement to set all alarm outputs to idle state. Alarm
outputs whose switching condition is still met will be activated again after 1 s. This func-
tion is used to reset alarm outputs of the type
HOLD
if the switching condition is no longer
met.
By pressing key BRK, the measurement is stopped and the main menu is selected. All
alarm outputs will be de-energized, independently of the programmed idle state.
17.12.3 Alarm outputs during transducer positioning
At the beginning of the transducer positioning (bar graph display), all alarm outputs
switch back to the programmed idle state.
If the bar graph is selected during the measurement, all alarm outputs will switch back to
the programmed idle state.
An alarm output of the type
HOLD
that has been activated during the previous measure-
ment will remains in idle state after the transducer positioning if its switching condition is
no longer met.
The switching of the alarms into idle state will not be displayed.
17.12.4 Alarm outputs during measurement
An alarm output with switching condition
MAX
or
MIN
will be updated max. once per sec-
ond to avoid humming (i.e. fluctuation of the measured values around the value of the
switching condition).
An alarm output of the type
NON-HOLD
will be activated if the switching condition is met.
It will be deactivated if the switching condition is no longer met. The alarm remains acti-
vated for at least 1 s even if the switching condition is met for a shorter period of time.
