Sensor Break Indications
This device detects input fault conditions.
(OVERRANGE, UNDERRANGE OR SENSOR
BREAK). When the process variable exceeds the
span limits an OVERRANGE condition will appear
as:
An UNDERRANGE condition will appear as:
A sensor break is signalled as "OPEn”. On the mA/
V input, a sensor break can be detected only
when the range selected has a zero elevation (4/
20 mA, 12/60 mV, 1/5 V or 2/10 V.)
On the RTD input "shrt" is signalled when input
resistance is less than 15 Ω (short circuit sensor
detection).
This device detects reference junction errors or
errors on the internal autozero measurement.
When a fault is detected the output goes OFF and
the alarm assumes an upscale/downscale reading
in accordance with r7.

1) When a configuration parameter error is
detected, repeat the configuration procedure of
that specific parameter.
2) If an error 400 is detected, press and hold the
key and press the key and load the default
parameters; then repeat the control parameter
setup.
3) For all other errors, contact your
Service Representative.
