Status Warning The following figure shows the status warnings for register 5.
*A range warning is issued when a channel input is outside the rated input value, as
shown in the following table. Warning bits stay on after out of range bits are set. An
out-of-range bit is set when a channel input exceeds the rated input value by 2.4%.
Out of range bits are also set if inputs drop below 0.5V (1 ... 5V mode) or 2.08 mA
(4 ... 20 mA mode).
When configured for current inputs (jumper installed between IN(+) and SENSE
terminals), a broken field wire results in a zero current reading. If 4 ... 20 mA is
selected, fault LEDs and warning/out of range and I/O Map Status Byte bits are
displayed.

Possible Equipment Failure
When configured for voltage inputs (no jumper installed between In(+) and sense
terminals), if a broken field wire occurs, readings will be non-zero and not
predictable.
Failure to follow these instructions can result in injury or equipment damage.
