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.
