Signal: Comp1
OutRange: 0-20 mA
Low Scale: 0.00
Max Scale: 100.00
AutoScale: Yes
FailMode: Live
0/4 mA: 0.00
20 mA: 100.00
Hold: No
"Out(put) range":
• 0-20 mA (dead zero) generates a 20 mA
signal, if a concentration is measured at
the upper limit of the signal range. A 0 mA
signal is generated if the sample gas con-
centration equals the value specied with
"LowScale" .
• 4-20 mA (life zero): A 4 mA signal is gene-
rated if the concentration equals the value
specied with "LowScale", thus enabling to
detect e.g. a broken cable.
"Fail mode" selects the output´s behaviour un-
der failure conditions, considering or not, the
NAMUR recommendation NE 43. NE 43 denes
output signals enabling to detect different types
of failures/status (see table 6-1): The related
information is transmitted as a current signal,
but outside the (0)4-20 mA measurement signal
range.
Available options:
Track: NE 43 not considered.
HIGH + 10%: NE 43 failure signal level:
"above".
LOW - 10%: NE 43 failure signal level:
"below".
6.2.3 Setup Menu
Enter a concentration, to equal the low output
limit (0 or 4 mA)
Enter a concentration, to equal the high output
limit (20 mA)
Enable (Yes) or disable (No) output autosca-
ling.
Note!
Factory settings are OutRange: 4-20 mA and
FailMode: LOW - 10%, if not changed at time
of order.
