Table 2: Hold Functions
*Value does not affect the function type
**Holds indefinitely or until triggered
***Function available only for FA Models
6.2.9 Setpoints
The two Setpoints are deactivated by default (alarm mode). Activating and adjusting the Setpoints is accomplished through software. Once one or both Setpoints are activated the relay changes state as the current temperature passes the setpoint temperature.
6.2.10 Deadband
Deadband is a zone of flexibility around the Setpoint. The alarm does not go abnormal until the temperature exceeds the Setpoint value by the number of set deadband degrees. Thereafter, it does not go normal until the temperature is below the Setpoint by the number of set deadband degrees. The Deadband is factory preset to ± 2° C or F of Setpoint value. Adjusting to other values is accomplished through software. For information on the sensor’s communication protocols, see section 9 Programming Guide on page 39. The following figure is an example of the Deadband around a Setpoint temperature of 960°C (1760°F).
