Alarm Deadband
This 4-byte real, expressed as percentage . As an example, if the Low alarm is set to 8%, and this parameter is set to 1%, the
default, then if the Low Alarm has occurred, the positioner needs to move back to 9% in order for the alarm to be cleared from
the secondary status .
Please note, the alarm is also recorded in the historical status . Thus it is possible to check if an alarm had occurred since the
last reset of historical status .

Internal Electronics Temperature Lower Limit
This is a 4-byte real field that allows the user to set a minimum value for the internal electronics temperature . If the internal
temperature of the positioner is outside the Lower Temperature Limit displayed in the alarms page, an alarm will be raised .
The diagnostic bit remains set as long as the condition is valid .
Default value is – 40° C (– 40° F) . Operating the positioner below this limit may cause damage to the instrument .

temperature of the positioner is outside the Upper Temperature Limit displayed in the alarms page, an alarm will be raised .
The diagnostic bit remains set as long as the condition is valid .
Default value is 80° C (176° F) . Operating the positioner above this limit may damage the instrument and violate electrical
