7.3 Analog Safety output
All analogue output values in the table below have a ± 0.25 mA range applied and are in accordance with
recommendations by NAMUR NE043 (2003) and NE107 (2017).

Comment
Over range
4***
20 mA
20 or 21 mA
Signalled if gas concentration is
measured above the configured
range.
Default the detector is to signal 100
%FS (20 mA) and not over range
since high concentrations of gas do
not have a negative effect on the
detector.
Normal
Operation
3***
4 - 20 mA
Not
configurable
The current loop output is
configured such that 4 mA
represents 0%FS and 20 mA
represents 100% FS.
Maintenance
Request
5
3 mA
1 - 3.5
Output if optics is getting dirty and it
is recommended to clean it soon.
Detector is still detecting gas inside
specification.
***Will output gas value if detection
above 7 %FS.
Out of
Specification
6
3 mA
Signalled if temperature is above or
below rating of this Detector.
Detector will measure gas, but the
accuracy of the Gas Detection might
be outside specification.
***Will output gas value if detection
above 7 %FS.
Function
Check
2
2 mA
This value is activated if the
Operator has set the detector into
Service mode. For example if a loop
test is performed by the Operator.
Failure
1
1 mA
No gas detection due to one of the
following:
• Detector is booting up
• Beam Block
• Faulty detector
Please consult chapter “10
Troubleshooting”.
< 0.5 mA
Power supply fault or not booted up.
No gas detection and no HART communication.
*A lower number will be prioritized first.
**Configurable through HART or Modbus RTU.
