D Instrument Temperature— Current Instrument Temperature.
Process Temperature
D Hi Enable— On or Off. Process Temperature High Enable activates checking of the process variable temperature
against the Process Temperature High Threshold. The Process Temperature High Alert is set if the process
temperature rises above the Process Temperature High Threshold. Once the alert is set, the process variable
temperature must fall below the Process Temperature High Threshold by the Temperature Deadband before the
alert is cleared. See figure 4‐11.
D Hi Threshold— Process Temperature High Threshold is the process variable temperature, in temperature units,
which, when exceeded, will set the Process Temperature High Alert.
D Lo Enable— On or Off. Process Temperature Low Enable activates checking of the process temperature against the
Process Temperature Low Threshold. The Process Temperature Low Alert is set if the process temperature falls
below the Process Temperature Low Threshold. Once the alert is set, the process temperature must rise above the
Process Temperature Low Threshold by the Temperature Deadband before the Alert is cleared. See figure 4‐11.
D Lo Threshold— Process Temperature Low Threshold is the process variable temperature, in temperature units,
which, when violated, will set the Temperature Low Alert.
D Process Temperature displays the process temperature stored in (or measured by) the instrument for reference.
D Process Temperature Source is the source of process temperature parameter for reference.
D Usage— If Process Temperature Source is 'Manual Entry', the only use for the Process Temperature alerts would be
to identify an entry outside of the compensation table range.
Temperature Deadband is the amount the temperature, in temperature units, must change to clear a temperature
alert, once it has been set. The deadband applies to all the temperature alerts. See figure 4‐11.
