The sensor leads break can be signalled as:
- for TC/mV input
: OVERRANGE or UNDERRANGE
selected by a solder jumper
- for RTD input : OVERRANGE
- for mA/V input : UNDERRANGE
Note: On the mA/V input the leads break can be detected
only when the range selected has a zero elevation (4/20
mA or 1/5 V or 2/10 V)
On RTD input a special test is provided to signal
OVERRANGE when input resistance is less than 15 ohm
(Short circuit sensor detection).
ERROR MESSAGES
The instrument performs same self-diagnostic algorithm.
When an error is detected, the instrument shows on the
lower display the “Err” indication while the upper display
shows the code of the detected error.
ERROR LIST
SEr Serial interface parameter error
100 Write EEPROM error.
150 CPU error.
200 Tentative to write on protected memory.
201 - 2xx Configuration parameter error. The two
less significant digits shown the number of
the wrong parameter (ex. 209 Err shows
an Error on P9 parameter)
299 Error in control outputs selection
301 Error on calibration of the selected input
307 RJ input calibration error
320 Linear output calibration error
400 Control parameters error
500 Auto-zero error
502 RJ error
510 Error during calibration procedure
NOTE
1) When a configuration parameter error is detected, it is
sufficient to repeat the configuration procedure of the
specify parameter.
2) If an error 400 is detected, push the t push-button
and, maintaining the pressure, push the s push-button
and load the default parameters; at this point repeat
control parameter setting.
3) For all the other errors, contact your supplier.
