ERROR MESSAGES
Overrange, Underrange and
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.
Error Messages
On power up, 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 |
200Error on "protect register" in EEPROM
XXX Configuration parameter error.
301Error on calibration of selected input.
307rj input calibration error.
400Error on operative parameters.
500Error on autozero measurement.
502Error on reference junction measurement.
510Error 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, 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.
