DLC3010 Digital Level Controller Specifications (continued)
Transient Voltage Protection: The loop terminals are
protected by a transient voltage suppressor. The
specifications are as follows:
Pulse Waveform
Max V
CL
(Clamping
Voltage) (V)
Max I
PP
(Pulse Peak

Rise Time
(ms)
Decay to
50% (ms)
10 1000 93.6 16
8 20 121 83
Note: μs = microsecond
Ambient Temperature: The combined temperature
effect on zero and span without the 249 sensor is less
than 0.03% of full scale per degree Kelvin over the
operating range -40 to 80_C (-40 to 176_F)
Process Temperature: The torque rate is affected by
the process temperature (see figure 1). The process
density may also be affected by the process
temperature.
Process Density: The sensitivity to error in knowledge
of process density is proportional to the differential
density of the calibration. If the differential specific
gravity is 0.2, an error of 0.02 specific gravity units in
knowledge of a process fluid density represents 10%
of span.
Electromagnetic Compatibility
Meets EN 61326‐1 and EN 61326‐2‐3
Immunity—Industrial locations per Table 2 of
EN 61326‐1 and Table AA.2 of EN 61326‐2‐3.
Performance is shown in table 1 below.
Emissions—Class A
ISM equipment rating: Group 1, Class A
Supply Requirements (See figure 3)
12 to 30 volts DC; instrument has reverse polarity
protection.
A minimum compliance voltage of 17.75 is required
to guarantee HART communication.
Compensation
Transducer compensation: for ambient temperature.
Density parameter compensation: for process
temperature (requires user-supplied tables).
Manual compensation: for torque tube rate at target
process temperature is possible.
Digital Monitors
Linked to jumper-selected Hi (factory default) or Lo
analog alarm signal:
Torque tube position transducer: Drive monitor and
signal reasonableness monitor
User-configurable alarms: Hi-Hi and Lo-Lo Limit
process alarms
HART-readable only:
RTD signal reasonableness monitor: When RTD
installed
Processor free-time monitor.
Writes-remaining in Non Volatile Memory monitor.
User-configurable alarms: Hi and Lo limit process
alarms, Hi and Lo limit temperature alarms, Hi and Lo
limit electronics temperature alarms
Diagnostics
Output loop current diagnostic.
LCD meter diagnostic.
Spot specific gravity measurement in level mode: used
to update specific gravity parameter to improve
process measurement
Digital signal-tracing capability: by review of
“troubleshooting variables”, and
Basic trending capability for PV, TV and SV.
LCD Meter Indications
LCD meter indicates analog output on a percent scale
bar graph. The meter also can be configured to
display:
Process variable in engineering units only.
Percent range only.
Percent range alternating with process variable or
Process variable, alternating with process temperature
(and degrees of pilot shaft rotation).
