Introduction; General; Symbols; Theory Of Operation - Turner Designs TD-107 5.0 Operation Manual

1.0 INTRODUCTION

This operations manual is
applicable to instruments with
serial numbers of 2000001F and
greater. If you require an
operations manual for an
instrument with an earlier serial
number, please contact NAG
Marine for assistance.

1.1 General

This manual contains instructions for the
installation, operation and maintenance of
5.0
the TD-107 OCM. For information
regarding the installation, operation and
maintenance of associated equipment
supplied by NAG Marine, refer to the
separate manual supplied with those
products.
Improper installation, use,
application or unauthorized
servicing of this equipment
voids all warranties.
5.0
The TD-107
operated, and maintained
according to this manual to
remain in compliance with DNV TAP NO.
771.61 regulations. Operation of the TD-
5.0
107 OCM in a manner other than
described here may be documented by
the instrument and may result in the
invalidation of the DNV TAP NO. 771.61
Certification. Failure to adhere to the
directions and recommendations exactly
as presented in this manual may result in
oil discharges violating DNV TAP NO.
771.61 regulations.
5.0
The TD-107 Oil Content Monitor (OCM) is
a DNV TAP NO. 771.61 certified 5 ppm
Bilge Alarm. Its primary function is to
monitor bilge water oil content and facilitate
the activation of discharge control devices
must be installed,
TD-107
to divert bilge water discharge in the event
oil content exceeds 5 ppm. The TD-107
OCM also permits process monitoring
through system-function relays, oil content
relays, and analog sample concentration
outputs. Compared with oil content
detection technologies that utilize turbidity
or light scatter techniques, the TD-107
OCM offers:
•
Resistance to high oil content readings
resulting from suspended non-oil
particles.
•
Selectively tuned optics to minimize
chemical interferences.

1.2 Symbols

The following symbols are used to call
attention to specific types of information.
A warning to use caution! In
some instances, personal injury
or damage to the TD-107
may result if these instructions are not
followed properly.
An explanation or information of
interest.
If the manual instructs the user to press a
key on the instrument, the designated key
will be CAPITALIZED in boldface type
enclosed by < >.
Display screen names will be in boldface
type and in ALL CAPITALS.
References to appendixes, tables and
figures will be in boldface type and in
italics.

2.0 THEORY OF OPERATION

5.0
The TD-107 OCM measures the oil
content of post oily water separator (OWS)
effluent via fluorescence. Fluorescence
occurs when a molecule—in this case a
hydrocarbon molecule—relaxes to its
ground state after being electronically
excited. Fluorescent hydrocarbons absorb
light—excite— at one wavelength and emit
light—relax— at a longer (less energetic)
wavelength. The emitted light is filtered and
