1.1.2 ALARM DEADBAND
To prevent oscillating of the alarm output when the measured temperature hovers
around the alarm setpoint, a deadband may be specified. The deadband is defined as
a percentage of the setpoint for all 16 alarm settings.
For high alarms, the alarm output will be set when the measured temperature reaches
the high alarm setpoint but will not be cleared until the temperature drops below its
lower deadband limit.
For low alarms, the alarm output will be set when the measured temperature drops
below the low alarm setpoint and will not be cleared until the temperature rises
above its upper deadband limit.
