DLC3010 Digital Level Controller
Configuration
May 2018
D Lower Range Value is the lowest value of the primary variable that the digital level controller is currently configured
to measure in the 4 to 20 mA loop.
PV Deadband— The Primary Variable Deadband is the amount the primary variable, in engineering units, must change
to clear a primary variable alert, once it has been set. The deadband applies to all the primary variable alarms. See
figure 4‐10.
Alarm Jumper allows the reading of the jumper for reference.
Refresh Jumper— Method for reading alarm jumper position if it was changed while communicating with instrument.

Temperature

Field Communicator Configure > Alert Setup > Temperature (2-3-2)
Follow the prompts on the Field Communicator display to set the following temperature alerts.
Instrument Temperature
D Hi Enable— On or Off. Instrument Temperature High Enable activates checking of the instrument temperature
against the Instrument Temperature High Threshold. Instrument Temperature High Alert is set if the instrument
temperature rises above the Instrument Temperature High Threshold. Once the alarm is set, the instrument must
fall below the Instrument Temperature High Threshold by the Temperature Deadband before the alarm is cleared.
See figure 4‐11.
D Hi Threshold— Instrument Temperature High Threshold is the instrument electronics temperature, in temperature
units, which, when exceeded, will set the Electronics High Alert.
D Lo Enable— On or Off. Instrument Temperature Low Enable activates checking of the instrument temperature
against the Instrument Temperature Low Threshold. Instrument Temperature Low Alert is set if the instrument
temperature falls below the Instrument Temperature Low Threshold. Once the alarm is set, the instrument must
rise above the Instrument Temperature Low Threshold by the Temperature Deadband before the alert is cleared.
See figure 4‐11.
D Lo Threshold— Instrument Temperature Low Threshold is the instrument electronics temperature, in temperature
units, which, when violated, will set the Instrument Temperature Low Alert.
