ERROR MESSAGES
Overrange, Underrange and
Sensor Break Indications
This device detects process variable faults
(OVERRANGE, UNDERRANGE OR SENSOR BREAK).
When the process variable exceeds the span limits
established by configuration parameter r1 an
OVERRANGE condition will appear as:
An UNDERRANGE condition will appear as:
A sensor break is signaled 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 resis-
tance 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.
Error Messages
On powerup, the instrument performs a self-diagnostic
test. When an error is detected, the lower display shows
an "Er" indication while the upper display shows the code
of the detected error.
Error List
100 Error in EEPROM writing
150 Short circuit on CPU's outputs
200 Error on "protect register" in EEPROM
XXX Configuration parameter error.
301 Error on calibration of selected input.
307 rj input calibration error.
400 Error on operative parameter.
500 Error on autozero measurement.
502 Error on reference junction measurement.
510 Error during calibration procedure.
Dealing with Error Messages
1) When a configuration parameter error is detected,
repeat the configuration procedure of that specific
parameter.
2) If an error 400 is detected, simultaneously press
the
and keys to load the default parameters
and then repeat the control parameter setup.
3) For all other errors, contact your
Service Representative.
