160 Parameters
High Action is taken whenever signal is above
Supervision high limit + (0.5 * hysteresis). Action
is deactivated whenever signal is below
Supervision high limit - (0.5 * hysteresis).
2
Abs low Action is taken whenever absolute value of signal
is below absolute value of Supervision low limit -
(0.5 * hysteresis). Action is deactivated whenever
absolute value of signal is above absolute value
of Supervision low limit + (0.5 * hysteresis).
3
Abs high Action is taken whenever absolute value of signal
is above absolute value of Supervision high limit
+ (0.5 * hysteresis). Action is deactivated
whenever absolute value of signal is below
absolute value of Supervision high limit - (0.5 *
hysteresis)
4
Both Action is taken whenever signal is above
Supervision high limit + (0.5 * hysteresis) or
below Supervision low limit - (0.5*hysteresis).
Action is deactivated whenever signal is in
between Supervision high limit - (0.5 * hysteresis)
and Supervision low limit + (0.5*hysteresis).
5
Abs both Action is taken whenever absolute value of signal
is above absolute value of Supervision high limit
+ (0.5 * hysteresis) or below absolute value of
Supervision low limit - (0.5*hysteresis). Action is
deactivated whenever absolute value of signal is
in between absolute value of Supervision high
limit - (0.5 * hysteresis) and absolute value of
Supervision low limit + (0.5*hysteresis).
6
Hysteresis Action is taken whenever signal is above
Supervision high limit + 0.5 * hysteresis. Action is
deactivated whenever signal is below
Supervision low limit - (0.5 * hysteresis). The
status is unchanged when signal value is in
between Supervision high limit + (0.5 *
hysteresis) and 'Supervision Low' limit - (0.5 *
hysteresis)
7
Low falling Action is taken whenever the signal falls from a
value higher than the Supervision low limit + (0.5
* hysteresis) to a value which is lower than
Supervision low limit - (0.5 * hysteresis).
Action is deactivated when the signal rises to a
higher value than Supervision low limit +
(0.5*hysteresis).
