ON THE AUXILIARY INPUT
When the remote set point signal exceeds the full scale value
programmed by "A.In.t" [C.d10], an OVERRANGE condition will
be shown on the lower display as shown in the following figure:
When the remote set point signal is lower than the initial scale
value programmed by "A.In.t" [C.d10], an UNDERRANGE
condition will be shown on the lower display as show in the
following figure:
These instruments are capable to detect, on the auxiliary input,
the sensor leads break condition.
When the sensor leads break condition is detected, the
instrument shows “OPEn” on the lower display.
NOTE : the leads break condition can be detected only if the
selected range has a zero elevation( 4/20 mA or 1/5 V or
2/10 V).
NOTES :
1) The fault conditions on the auxiliary input will be displayed
only if the relative indication has been selected (see "Display
function" at page. 62).
2) When a fault condition different from overrange or underrange
is detected on the auxiliary input, the alarms,the power
output and the analog retransmissions operate as in presence
of an underrange condition.
ERROR MESSAGES
At the end of each configuration parameter group modifiction the
instrument check the new parameters values.
At instrument start up in operative mode, all the parameters are
checked.
If an error is detected, the instrument will show:
- on the upper display,
the parameter family
CnF.x
for configuration parameters
GRP. x for run time parameters
CAL
for calibration parameters
where x is the number of the specific group where the
error has been detected.
