WARNING
DESCRIPTION
POSSIBLE CAUSES
INTERFACE
A connection problem with
Hamilton sensor.
Oxygen: mA value outside
range.
Oxygen: ECS (Electrical connec-
tion for this sensor) is outside
range.
HARDWARE
Hardware problem with Ham-
ilton sensor.
Supply voltage outside range.
QUALITY
A Hamilton sensor reports a
quality value under 35%.
The calibration was incorrectly
performed or was faulty.
If the fault continues after re-
peated cleaning and calibra-
tion, the sensor (or cap on the
oxygen sensor) must be re-
placed.
Conductivity: the sensor is out-
side the medium.
OVER TEMP
A Hamilton sensor reports the
temperature is too high.
Medium or ambient tempera-
ture too high.
Temperature measurement de-
fective.

Fault messages and effect on operation
FAULT
If an error occurs during operation, it has the following
effects:
A fault is a malfunction which prevents correct
measurement value acquisition.
The measuring values of the concerned sen-
sor/photometer go to 0.
Assigned current outputs go to the programmed
electrical current “If fault”.
Assigned limits are deactivated.
If an output for faults is programmed, it is activat-
ed.
When the
Fault
message appears,
the color of the
status display changes to
red
and the text de-
scribes the fault in question.
If the cause of the fault has been remedied, it is
automatically deleted.
