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 (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

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.
