Special Conditions for Use in European Gas
Performance Approval
Sensepoint XCD is approved for European Gas Performance with the following specific conditions:
• IEC/EN 60079-29-1 for CH
4
and C
3
H
8
with the measuring range 0 – 100 % LEL
• EN 45544-1/-3:2015 for CO (0 – 300 ppm) and H
2
S (0 – 50 ppm)
• EN 50104:2010 for O2 with the measuring range 0 – 25 % v/v (no inertisation)
• Only 4 – 20 mA is considered as a safety function. The other outputs are optional signals
outside the scope of the European gas performance approval. 4-20 mA output is refreshed at
least every two seconds.
• Analogue output signal status as a safety function:
≤ 1 mA: System and other faults
2 mA: Start-up, inhibit
4 – 20 mA: Gas reading range (when deadband is on)
22 mA: Over-range
• Analogue output shall be tested at least once a year to verify the operation of safety function.
Refer to chapter 9 of this manual for gas calibration and bump test. Refer to chapter 12.2 of
this manual for “FORCE CURRENT” menu.
• Sensepoint XCD flammable catalytic sensor would produce higher gas measurement when
located in 90° with respect to the air velocity. It is prohibited to install Sensepoint XCD
flammable catalytic sensor at 90° with respect to the air velocity for an application requiring
IEC/EN 60079-29-1 compliance.
