Automatic:
The alarm is reset the moment the alarm situation is no longer valid.
This unless you programmed an alarm duration. For a totalizer alarm this setting will
reset the totalizer as soon as the threshold has been exceeded.
Manual
: The alarm stays active until you manually reset the alarm through the touch
screen of the flow meter.
Input 1:
The alarm stays active until you activate input 1
Input 2:
The alarm stays active until you activate input 2
Reset trigger: (Note: this function only relates to alarm reset by input 1 or 2).
When you use input 1 or 2 as an alarm reset, you can set exactly on
which action the alarm is reset. If for example the input is a manual
push button, the rising edge is the moment that you push the button
and the falling edge the moment when you let go of the push button.
Please note that the reset overrides the alarm. Even if the alarm is
still valid, if you set this reset trigger to high level, the alarm is ignored until the level
becomes low again.
If the blue represents the input being active you can see the different trigger points below.
Output driver:
the output driver setting offers the possibility to invert the action from the
alarm switch and set the alarm to a predefined state which is convenient for testing systems.
The “Always low” and “Always high” override all alarm settings and flow signals. Please
make sure that you take precautions before you use these options in a “life” system.
