High and Low levels
–
define I/O value range. If I/O value enters or exits this range, FM1000
generates event. “Generate event” parameter defines when to generate event –
when value
enters defined range, exits it or both.
Averaging constant
–
it is an I/O event delay parameter. In some applications there is no
need to generate events on every I/O range enter/exit immediately. Sometimes it is necessary to
wait some time interval before event generating. Averaging constant allows setting I/O event
delay (averaging). If I/O value is entering or leaving predefined range, it must have same value
for Averaging constant time. 1 Averaging constant value equals about 100 milliseconds.
Param = AvgConst(sek) * 10. For example, Value 3 = 300ms.
In Deep Sleep mode there is no Averaging.
Note: I/O element’s “Movement” Averaging constant is interpreted as St

is a time interval required for accelerometer to be in the
moving state, to consider vehicle as moving.

Event Generating
Events happen when the value of enabled I/O intersects thresholds (enter, exit or on both)
predefined by High and Low level thresholds. Table below defines all available values of I/O
settings.
