Maintenance
S033 Dev. zero point too
high M Parameters set for measured
component
Check zero gas for pressure and
cleanness.
Perform maintenance on com‐
pressed air conditioning unit.
Perform manual zero point adjust‐
ment twice (menu: 2 Adjustment
→
1 Adjustment → 1 Zero point adjust‐
ment).
When message occurs again dur‐
ing next automatic zero point adjust‐
ment: Call SICK Service.

Check IO modules, check plug con‐
nectors and voltage supply, load
backup if necessary.
Otherwise: Call SICK Service.

S036 O
2
sensor failure M Call SICK Service.
S038 Current invalid M Analog output: Desired current
not reached.
Analog input: Current outside
valid range.
Check connections on the Analog
module.
S039 Current invalid M
S040 Flow too high M Call SICK Service.
S041 Flow too low M When pressure error, clear it first.
Sample gas flow too low and purge/
zero gas flow ok: Check/replace sam‐
pling filter
Sample gas flow and purge/zero gas
flow too low: Call SICK Service.
Purge/zero gas flow too low and
sample gas flow ok: Check all hose
