Setpoints
Each channel may be defined as a
setpoint
, which means that
the corresponding output will turn on upon crossing some level.
The setpoint user-defined selection also controls the
direction
of
the ‘setpoint indication’; that is, turn the output on upon crossing
the limit either
upwards
or
downwards
. In other words, the
direction
of the trigger is user-defined. Likewise, the user may
define a
hysteresis
behavior, e.g., the output turns on when the
temperature goes above some limit and only goes off again when
the temperature falls below another (lower) limit, thus eliminating
undesirable fluctuations in the status of the output.
