ALARM HYSTERESIS—A single adjustable
hysteresis is provided on alarms such that
when the alarm is OFF it activates at exactly
the alarm setpoint; when the alarm is ON, it
will not deactivate until the variable is 0.0 %
to 100 % away from the alarm setpoint.
Configure the hysteresis of the alarms based
on INPUT signals as a % of input range
span.
Configure the hysteresis of the alarm based
on OUTPUT signals as a % of the full scale
output range.
