11.0. TROUBLESHOOTING

5.0
Because the TD-107
hardware, software, and chemical elements,
it is important to collect all diagnostic data
first. A troubleshooting worksheet is
provided in Appendix G to facilitate data
collection. After collecting all data on the
worksheet, most problems can be solved
over the phone. Refer to the Service
Assistance Section for the appropriate
telephone numbers.
This guide assumes that all problems
associated with alarms have been resolved
first. Something as simple as a clogged inlet
line can lead to other alarm messages,
which could all be solved at one time simply
by clearing the obstruction. If there is no
System Alarm, it is highly probable that the
electronics of the instrument are functioning
properly. In that case, it is likely that the
problem is either mechanical, or has
resulted from another system problem, or
from the operator's unfamiliarity with the
unit.

The troubleshooting procedure works best
in this sequence:
1. Handle any alarms first (see 10.0.
Alarms and Advisories).
2. Determine whether the System Values
have been entered correctly (see
recorded values in Appendix B, and the
System Default Values in Appendix F,
Table 5).
3. Perform the diagnostics procedure as
described in the following section.
4. Determine whether the bilge water
process is behaving as expected.
Does the clean water read close to
zero on the HOME screen and the
check solution read the value provided
on the bottle label? Check the CAL
DATA screen (see Calibration Data
Screen) to determine whether the last
calibration seems correct
5. Complete the Troubleshooting
Worksheet (Appendix G).
6. Contact your NAG Marine
representative or NAG Marine directly at

Assistance/Returned Goods Section).
