available in the Expert
setup!)
Only for "Current" as the signal
and "4-20 mA" as the range
Only for "4-20 mA" or "1-5 V" as
the range and if "NAMUR NE43"
is "on"
Only for "Voltage" as the signal

Not available if "Pulse counter" is

Settings that lay down how this channel is to react under fault conditions
(e.g. cable open circuit, over range).
Fig. 39: Setup - Inputs - Universal inputs, Universal input x,
submenu "Fault mode"
Fault switches: switches the selected relay under fault conditions. The
terminal numbers are shown in brackets.
Picklist: not used, relay x (xx-xx)
Note: If there are several reasons for triggering a relay (e.g. 2 different
limit values), this must be set to "Collective relay" under "Setup ->
Outputs -> Relay -> Relay x".
Save event: stores a message in the event memory when a fault
condition occurs. Picklist: no, yes
NAMUR NE43:
Switch monitoring of the 4 to 20 mA range as per NAMUR
Recommendation NE43 on and off. The following error ranges apply
when NAMUR NE43 is switched on:
3.8 mA: under range (display shows: vvvvvv)
20.5 mA: overrange (displays shows: ^^^^^^)
3.6 mA or 21.0 mA: cable open circuit (display shows: - - - -)
Picklist: on, off
Time delay
The system only reacts to a cable open circuit/under range/overrange
(e.g. relay is switched) if this condition is present for the set duration at
least. Factory setting: 0 s
Cable open circuit:
Switch cable open circuit detection of the 1-5 V range on or off. If the
cable open circuit detection function is switched on, all values <0.8 V or
>5.2 V are regarded as a cable open circuit (display shows: - - - -)
Picklist: on, off
In the event of an error
Specify the value the unit should continue to use (for calculations) if the
measured value is not valid (e.g. cable open circuit).
Picklist: last valid value, range start, meas. range end, zero
1)
HIGH , value is invalid, free configuration
Error value
The unit continues calculating with this value if a fault occurs. See table
