▪ When SIGNAL FAULT is activated (YES) by default, if a fault
occurs, system sends the FAULT LEVEL signal below for all 4-
20mA channels. When it is set to (NO), 4-20mA outputs do not
signal FAULT LEVEL if a fault occurs and system keeps sending
live data on the outputs.
▪ FAULT (1.0mA by default) specifies the fault output level for all
system 4-20mA channels.
▪ OUTPUT < 4mA function defines the factor (0% by default) to be
applied on the stream value if the output value becomes smaller
than 4mA (negative result). This function allows the user to
clamp or reduce the effect of negative result on the 4-20mA
output value.
▪ For instance, if the OUTPUT value is set as 100%, 100% of the
negative result is sent as 4-20mA signal. If the setting is 50%,
50% of the negative results is sent as 4-20mA signal. When the
setting is 0%, no negative result is send and any negative result
is clamped to 4mA (0µgC/l) level.
▪ When OUTPUT MODE is programmed as BASIC above,
EXCLUDE RESULTS defines the number of stream analysis
reactions (3 by default) to be omitted after the zero and/or span
calibration/check reactions. This is achieved by keeping the
calibration output relay activated until the programmed number
of stream analysis is completed. In other words, the calibration
contact remains active for a programmable number of online
reactions after the completion of the calibration cycle. This
function helps to ignore any possible calibration impact on the
system response.
