MAINTENANCE
Do not break the provided tamper
evident DNV certification seals for
any reason. Breaking such seals will
invalidate the DNV certification of the
monitor.
When performing maintenance,
always move the inlet valve to the
maintenance position.
Improper installation, use,
application or unauthorized
servicing of this equipment voids all
warranties.
Proper maintenance and cleaning of
the TD-107 sample cell is a key
component of consistent oil content
monitoring. Significant build-up of residue,
iron oxide, or other foreign material on the
inner quartz tube can materially affect the
measurement of the fluorescent properties
of the oil. Consistently following these
simple cleaning and maintenance
procedures will ensure accurate and reliable
operation from the monitor.

9.1 Battery Back-Up

5.0
TD-107 OCM System Values are retained
in battery back-up memories for up to five
years. However, the Start-Up procedure
should be followed to ensure oil content
monitor calibration and control settings are
correct if the unit has been disconnected for
any length of time. The battery is not user-
serviceable. The back-up battery should be
replaced during re-calibration of the TD-
5.0
107 OCM by a factory-authorized dealer.
The Datalogger data are retained in battery
back-up memories for up to seven years.
The battery is not user-serviceable. The
back-up battery should be replaced during
re-calibration of the TD-107
factory-authorized dealer.

9.2 Preventative Maintenance

Preventative maintenance should be
performed to ensure optimum monitor
operation and maximum life. The two
maintenance actions that the user can
perform are Sample Cell Cleaning and
Desiccant Plug Replacement.
9.2.1 Desiccant Plug
5.0
The TD-107 OCM has been assembled
with a new desiccant plug to ensure the
area surrounding the sample cell is free of
any moisture. As the desiccant absorbs
moisture, it will change from a light blue to a
light pink at the saturation point. The
desiccant should be promptly replaced upon
turning pink or annually (from the date of
installation) if no color change is noted.
Refer to 9.3. Replacement Parts for the
replacement desiccant plugs part number.
Failure to regularly replace the
desiccant plug can result in
incorrect operation and measurement.
9.2.1.1 Desiccant Plug Replacement
For replacement of the desiccant plug,
perform the following steps; refer to the
General Arrangement Drawings:
1. Move the inlet valve to the maintenance
position.
2. Unscrew the existing desiccant plug.
3. Remove the new desiccant plug from its
packaging.
4. Install the new desiccant plug by hand-
tightening onto the monitor.
5. Move the inlet valve to the flow position.
9.2.2 Cleaning the Sample Cell
Sample cell cleaning frequency is
dependent on the quality of the water
sample being monitored. The sample cell is
unlikely to clog, but over time residue can
build up on the inside of the quartz cuvette,
especially where oily water is involved. A
fouled or discolored sample cell can result
in low or erratic readings. Sample cell
cleaning steps are outlined in Section 5.3.2.
