Probe EL. too hot M ainte-
nance
Electronics too hot. Ambient temperature too
high?
Allow device to cool down.
Air purge low Volume flow below set limit. Check purge air supply.
Filter watch Flow monitor. Check purge air supply.
p no signal No signal from pressure sensor. Check purge air supply.
p out of range Sample gas pressure < 500 or > 1200 hPa
(mbar).
---
t air no signal Broken sensor. Please contact SICK Customer Service.
[t] no signal Broken sensor.
EEPROM defect EEPROM defective.
Heat no signal Heater fault.
Heater < 1.5 A
Heater defect
Heating too low
No com.
Communication error to optic head and/or
reflector.
Check connection cables.
System Systemstart X tended This message is entered during each system
start.
Shows when last system start was made.
Zero adjust The start of an adjustment is recorded in the
logbook.
Shows when last adjustment was made.
Boxmeasuring The start of filter box measurement is recorded
in the logbook.
Shows when last filter box measurement was made.
Reflector search Search for reflector failed Check alignment, see “Alignment check (auto-
matic optical alignment check; option)”, page
45 .
Reflector contaminated or defective.
Light intensity weakness too strong on measuring
path.
P Substitute value M ainte-
nance
Calculation is made with a substitute value
because of a pressure measurement error.
The set input (probe, analog input, SCU) shows errors
and the substitute value is therefore used for
calculation.
T Substitute value M ainte-
nance
Calculation is made with a substitute value
because of a temperature measurement error.
The set input (probe, analog input, SCU) of pressure
measurement shows errors and the substitute value
is therefore used for calculation.
