7.1 OUT OF RANGE7.1 OUT OF RANGE
7.1 OUT OF RANGE7.1 OUT OF RANGE
7.1 OUT OF RANGE
The instrument shows the UNDER RANGE and the OVER RANGE
with the following messages on the numerical display:
OVER RANGE UNDER RANGE
During out of range indications, alarm status, peak detection and
analog retransmission operate as in presence of the range limits.
NOTENOTE
NOTENOTE
NOTE: 1) The out of range indications follow the readout scaling so
that when a reverse scaling is set, over range and under
range are reversed also.
2) The out of range indication is shown when the input signal
is 2% higher or 2% lower of the max. and min. scale
values respectively.
To eliminate the OUT OF RANGE condition, proceed as follows:
1) Check the input signal source and the connecting line.
2) Make sure that the input signal is in accordance with instrument
configuration. Otherwise, modify the input configuration (see
chapter 3.2).
3) Send back the instrument to your supplier for a check.
7.2 OPEN INPUT CIRCUIT7.2 OPEN INPUT CIRCUIT
7.2 OPEN INPUT CIRCUIT7.2 OPEN INPUT CIRCUIT
7.2 OPEN INPUT CIRCUIT
This instrument is able to identify the open circuit for 4-20 mA, 1-5 V,
2-10 V, TC and RTD inputs.
The open input circuit condition is shown by "OPEn" on the numerical
display.
If TC or RTD input is selected, it is possible to set, in configuration
procedure, the outputs status associated to the open input condition.
(see para. 3.c)
For mA and V input the instrument associates this status to under
range condition .
NOTENOTE
NOTENOTE
NOTE: For 4 - 20 mA, 1-5 V and 2-10 V inputs, the open input circuit
condition is shown when the input signal is lower than the minimum
range value minus 4 % of the input span.

7.3 ERRORS7.3 ERRORS
7.3 ERRORS
Diagnostics are made at instrument switch-on and during normal
mode of operation.
If a fault condition (error) is detected, the display will show the
message "E" followed by the relative error code.
The following is a list of possible errors in numerical order.
Also causes, instrument output conditions and possible remedies are
briefly described.
Same errors reset the instrument; if the error persist, send back the
instrument to your supplier
