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 List
100 Error in EEPROM writing
150 Short circuit on CPU's outputs
200Error on "protect register" in EEPROM
XXX Configuration parameter error.
301 | Error on calibration of selected input. |
307 | rj input calibration error. |
400Error on operative parameter.
500Error on autozero measurement.
502Error 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.
