10.5 Alarm / Advisory Definitions

10.5.1 High (5 ppm) Signal
If the measured oil in water concentration
exceeds 5.0 ppm, HIGH OIL READING will
be displayed.
10.5.2 Zero Signal
If the measured oil in water concentration
equals 0.0 ppm, ZERO OIL READING will
be displayed.
10.5.3 LED Failure
If LED output power drops below the level
deemed acceptable by the factory for 10
seconds, LED FAILURE will be displayed.
This measurement is taken across the
sample cell from the UV light source. A
sample which contains so much oil or is so
dark that only 10% or less of the UV light
can pass will also trigger a LED Failure
alarm.
10.5.4 High Water Temperature
If the bilge sample temperature exceeds 60
° °
C [140 F] for 10 seconds, H2O
TEMPERATURE will be displayed.

10.5.5 Cell Condition
If the voltage from the light transmitted
through the sample cell falls below the level
deemed acceptable by the factory for at
least 10 seconds, CELL CONDITION will be
displayed. This typically occurs because
10.5.6 Separator
If the TD-107
input signal is not satisfied, SEPARATOR
will be displayed. This could indicate a
problem with the OWS or a faulty separator
input connection.
10.5.7 Flow
If the input signal for sample flow is not
satisfied, FLOW HAS STOPPED will be
displayed. This could indicate a blockage in
the sample line, a closed valve prior to the
inlet or a faulty flow input connection. This
alarm is also activated when the inlet valve
is closed to put the instrument in
