5.6 Sensor failure monitoring according to NE43
There is possibility of the monitoring of the sensor failure in ConSoft. The difference between
the monitoring of the sensor failure in ConSoft and HART is shown in Table 9 below.

Sensor break

off, downscale (
≤3.6 mA),
upscale (
≥ 21 mA) and
other value
upscale (
≥ 21 mA)
Configuring of the transmitter in ConSoft for
other value lower than 21 mA is interpreting
as downscale in the transmitter otherwise
as upscale during HART configuration.
Sensor short
off, downscale (
≤3.6 mA),
upscale (
≥ 21 mA) and
other value
upscale (
≥ 21 mA)
Configuring of the transmitter in ConSoft for
other value lower than 21 mA is interpreting
as downscale in the transmitter otherwise
as upscale during HART configuration.
Sensor low Isolation
off, downscale (
≤3.6 mA),
upscale (
≥ 21 mA) and
other value
off
Not permitted for SIL transmitters.
Configuring of the transmitter in ConSoft for
other value lower than 21 mA is interpreting
as downscale in the transmitter otherwise
as upscale during HART configuration.

NOTE!
Configuring of the sensor failure in ConSoft for other settings that are not according Namur
NE43 generates an error message!
5.7 Factory configuration and calibration of the C520/C520X / R520/R520X
The C520/C520X / R520/R520X transmitters are delivered with a factory configuration Pt100
(
α=0.00385), 4-wire connection, 0…+100°C / +32…+212°F or configured according to customer’s
requirements (See the Table 3 for detailed information).
Due to the long-term drift of max ±0.01°C or ±0.01% of span per year, a recalibration of the
transmitter is normally not needed. Should you for any reason require the recalibration, the
transmitter must be returned to the factory.
