STATUS MESSAGES
9
Error messages not listed: The fault cannot be rectified by the customer. Contact one of the SICK service points.
Test gas flow rate
too high
System error,
open
The error can only occur during an O
2
sensor adjustment and signals an
insufficient test gas flow during the adjustment. It can be reset by the
user. A new successful adjustment also resets the error.
Possible causes:
Test gas pressure too high, test gas flow volume
incorrectly set, test air flow volume incorrectly set
O
2
sensor offset
too low
System error,
open
The error can only occur during an O
2
sensor adjustment. It can be reset
by the user. A new successful adjustment also resets the error.
Possible causes:
Reference air supply insufficient, process pressure too
high, wrong test gas (not with test air), O
2
sensor defective.
O
2
sensor offset
too high
System error,
open
The error can only occur during an O
2
sensor adjustment. It can be reset
by the user. A new successful adjustment also resets the error.
Possible causes:
Wrong test gas (not with test air), test gas flow volume
too low, O
2
sensor defective
O
2
sensor slope
too low
System error,
open
The error can only occur during an O
2
sensor adjustment. It can be reset
by the user. A new successful adjustment also resets the error.
Possible causes:
Wrong test gas, test gas flow volume too low, filter
damager, filter head not fitted, O
2
sensor defective.
O
2
sensor slope
too high
System error,
open
The error can only occur during an O
2
sensor adjustment. It can be reset
by the user. A new successful adjustment also resets the error.
Possible causes:
Wrong test gas, O
2
sensor defective.
O
2
sensor signal
instable
System error,
open
The error can only occur during an O
2
sensor adjustment. It can be reset
by the user. A new successful adjustment also resets the error.
Possible causes:
Test gas flow volume too low, filter damaged, process
pressure fluctuations too high.
mA input for pro-
cess pressure
System error,
open
Circuit open or pressure transmitter signal
Lower than 3.6 mA / higher than 20.4 mA
Error REMOTE
module
System error,
open
Signals a hardware error of the REMOTE module.
Possible cause:
The REMOTE module is defective.
