3
Motor Speed
Set when the motor speed is outside the
prescribed limits. It may occasionally
be set for short periods of time (10 to 15
seconds), but if it persists, the user
should consult with a Campbell
Scientific application engineer.
4
TEC Temperature Set when the infrared detector
temperature is outside the prescribed
limits. It may occasionally be set for
short periods of time (10 to 15 seconds),
but if it persists the user should consult
the factory. Verify that ambient
temperature and power supply voltage
are within the specifications.
5
Source Power
Set every time the infrared source power
is outside the prescribed limits. It may
occasionally be set for short periods of
time (10 to 15 seconds), but if it persists,
the user should consult a Campbell
Scientific application engineer. Verify
that ambient temperature and power
supply voltage are within specifications.
6
Source
Temperature
Set when the internal temperature is
outside the specified safe operation
limits (−35° to 55°C). If this flag is set
the sensor head will be turned off until
the internal temperature is within the
range −30° to 50°C. If the flag is set
and ambient temperature is within the
specified range, consult with a Campbell
Scientific application engineer.
7
Source Current
Set when the infrared source current is
outside the prescribed limits. It may
occasionally be set for short periods of
time, but if it persists the user should
consult with a Campbell Scientific
application engineer.
8
Off
Set when the analyzer head is powered
off by the user, the datalogger program,
or the EC100 operating system when the
LIGHT_TEMP flag is set.
9
Synchronization
Set when sampling errors are detected.
Sampling errors are most often caused
by strong electromagnetic interference.
If the flag persists, consult with a
Campbell Scientific application
engineer.
