10.0 ALARMS and ADVISORIES

The primary purpose of the TD-107
is to act as an alarm to oil content greater
than 5 ppm. There are only two alarms
required by the DNV TAP NO. 771.61
regulation; the High (5 ppm) Signal Alarm
and the Zero Signal Alarm. Other alarms
that are recorded by the Datalogger relate
to system status. These alarms are the LED
Failure, Cell Condition, Separator, Flow and
High Temp alarms. While not mandatory,
these system alarms provide valuable
information and can help greatly in
troubleshooting instrument problems and
suspected measurement errors. The TD-
5.0
107 OCM has two advisories as well.
These are the Early Warning and
Maintenance Mode advisories. Refer to
Table 3 and Appendix F (Table 5) for
alarm default values.

10.1 Alarm Delay

To avoid unnecessary triggering of certain
alarms, the condition must be in effect for a
certain delay period (see Table 3).

10.2 Alarm Activation

When an alarm is triggered, "ALM" will
blink in the upper left-hand corner of the
HOME screen. Pressing <ESC> will display
the current alarm. Take the appropriate
action to clear the condition (see
Troubleshooting Section).
When the condition triggering the alarm is
cured, "ALM" will disappear from the
HOME screen.
Alarms cannot be aborted without curing the
problem.

10.3 Multiple Alarms

If multiple alarms are triggered, alarms will
be listed on the alarm screen when <ESC>
is pressed from the HOME screen. Alarms
are not listed in the order they occur.
Certain alarms will trigger other alarms
because a failure in one part of the unit
causes what appears to be a failure in
another part of the unit. For example,
putting the TD-107
5.0
OCM
Mode will trigger a Maintenance Mode
Advisory and a Flow Alarm since the inlet
valve has been closed and water is not
flowing through the instrument.

10.4 Alarm History

The alarm history can be viewed, by
pressing <
shows which alarms have been activated
since the alarm history screen was last
cleared. To clear this screen, press <>
five times while the alarm history screen is
displayed; "No Alarm Since Last Reset"
will be displayed. The alarm history does
not store or display the alarms in the order
in which they occurred.
mA will still send out the oil content
concentration.
