3.0 Installation
3.1 Mounting and Site Sele ction
The OCM is designed for wall mounting. If wall mounting is not practical, the
instrument can be mounted on any suitable surface. Choose a location that is easily
accessible for operation and service and ensure that the front display rests at eye level.
The overall mounting dimensions of the instrument are shown in Figure 1. For ease of
service there should be about 45cm (18”) free area above the OCM. This will ensure
enough room for calibrations and for cleaning the optical well. The recommended
mounting screws (four required) are M6 (or ¼”).
It is important that the OCM be mounted within 18 meters of the oily water separator to
comply with the IMO requirement for a respons e time of 40 seconds.
3.2 Plumbing
The recommended plumbing for the instrument is shown in Figure 4. The OCM is
designed with an integral flow regulator which limits the flow to between 0.8 – 1.3
liters/minute depending on the system backpressure. Ensure that you supply the OCM
with a process flow capable of sustaining thes e levels. Quick- connect fittings are s upplied
on the inlet and outlet of the OCM. These f ittings help speed up calibration procedures.
The OCM is designed for use with semi-rigid tubing (¼” OD X .170” ID). Opaque
tubing is recommended if the tubing will be exposed to sunlight. Using this semi-rigid
tubing, the ins trument should be installed within 18 me ters of the sample line to com ply
with the IMO r equirement for a respons e time of 40 seconds. A valve is supplied at the
inlet side of the instrument to ease the calibration and cleaning procedures.
Note: The quick-connect fittings are designed with a special shut-off feature to prevent
flow of the process through the OCM when the line is disconnected.
The optional clean water supply must be oil-free. The clean water connection, along with
the optional drain connection, allows the OCM to be easily calibrated for the clean water
condition. If your clean water supply is seawater, the OCM can be zero adjusted with the
local seawater.
3.3 Electrical Connections
All of the electrical connections to the OC M a re made at the fie ld te rminal box located on
the lower sec tion of the instrument. Wiring should be run in through the grommet closest
to the connection terminal bloc k. The cable diameter for these gr ommets is rate d for 4.3 –
11.9 mm (0.170 –0.470”).
To make connections, insert a 3mm(1/8”) flat blade screwdrive r into the top slot of the
terminal block. Pivoting the handle of the screwdriver up c a uses the clamp to lowe r. You
can now insert the wire. Releasing the tension raises the clamp and tightens the
connection. Please note that these terminal blocks will accept wire gauges A WG 24-14.
As you read the following sections, ple a se refer to Figure 3 for c la rification of the
electrical connections.
Please follow all local and government recommendations and methods for insta lla tion of
electrical connec tions to and between the instrument and peripher a l de vic e s.
OCM Rev. 3.9 (1/03) 3
3.3.1 Power Source
The power source re quired is 90 – 250VAC, 47- 90Hz. The power cons umption is 6VA.
Connections are made at the far right ha nd te rminals.
Please observe safe wiring practices. It is recommended that a circuit breaker or switch
be placed prior to the power connection to the OCM to allow for service.
Note: Only qualified electricians should be allowed to perform the installation of the
instrument as it involves a line voltage that could endanger life.
3.3.2 Relay Connections
Relay connections for Alarm 1 and Alarm 2 are located next to the power connection.
These relays are rated at 120-240VAC 2A for the mechanical. The optional solid state
relays are rated at 120-240VAC 1A.
The Sensor Alarm connection is located to the left of Ala rm 1. This rela y is rated for up
to 30VDC 2A.
3.3.3 4-20 mA Output
A 4-20 mA s ignal is pr ovided. This output is re fe renc ed to the sc ale of 0-30 P P M as s et at
the factor y but m ay be set to any por tion of the sc ale of 0-50 P PM. Connections f or the 420 mA are located next to the Sensor Alarm.
3.3.4 Unused Terminals
Located next to the 4-20mA outputs are some terminals that are not used in this
instrument. T he se terminals are not connected inside the ins trument and cannot be used.
3.4.5 Cabinet Integrity
To maintain the seal of the field terminal box, it is important to use suitable size cable
through the compression f ittings. If suitable size cable is not available, use vinyl tubing or
electrical tape to make up the differ ence. Tighten all compr ession fittings by hand. Do not
remove the plastic dowel plugs in unused fittings as these serve to complete the cabinet
seal. When clos ing the lid, ensure that no wires a re pinched and that the o-r ing is in good
condition. Tighten the four corner screws firmly.

4.0 Becoming Familiar with the Instrument
The user interface of the OCM has been designed with a 4 key Touch Pad and a digital
user display with two rows of display information.
4.1 The Touch Pad
The MODE key is used to cycle between the four modes of the OCM: AUTO
(measurement) mode, CAL 0 ADJ (Zero Adjust Calibration) mode, SETUP
(Instrument Configuration) mode, and CAL (Calibration) mode. The
the option (or mode) that is highlighted or chosen. The
through lists and to increase or decrease settings. Please refer to the Menu Flow Chart
(Figure 8) while becoming familiar w ith the operation of the OCM.
Note: 1.While in the CAL or SETUP modes the relays are set in the alarm condition.
2. The instrument has an integral time-out feature that automatically returns the
system operation to the AUTO mode from either the CAL or SETUP modes when
more than 5 minutes have passed with no keypad activity.
4.2 The Display
Figure 4 illustrates all the graphics on the user display. The upper row of the display (1)
is used for reporting the oil concentr ation (in PPM) and to provide user guidance in the
customer settings routine. The lower row of the display (2) is used to communicate error
messages and a lso to provide us er guidance. The display ha s several status indicators (3),
which indicate the current operation mode of the instrument. Finally, several indicators
around the screen provide guidance w hen the customer setting routine is being used and
when the calibration routine is being used. Please note that not all of the indications on
this screen will be used at any one tim e.

5.0 Routine Operation
The OCM is designed to m easur e and display the concentr ation of oil (in PPM by weight)
in the bilge water according to I.M.O. resolution MEPC. 60(33). Readings above 50
PPM are outsi de of the range of this instrument.
5.1 Routine Measurement
During normal oper ation, the instrument will have the AUTO block highlighted with the
current scal e displayed on the r ight side of the display, the m easure d reading on the upper
row of the display, and the current alarm level on the lower row of the display (see
illustration below).
The following steps describe how to measure the oil content of a sample using the
OCM:
1. Turn power on to the OCM. The instrument will be in the AUTO (measurement)
mode (the “AUTO” block should be illuminated). Allow instrument to w arm up for
at least 45 minutes.
2. When a continuous process stre am is flowing through the instrum ent, the instrument
will report the oil content of the sample by displaying it on the LCD screen.
3. Pressing the MODE button will allow you to sequentially access the calibration
routine (s ee section 6 for mor e information) and the configur ation/setup routine (see
section 7 for more information).
5.2 Security Access Feature
The OCM is equipped with a security access code feature that can be turned on or off
when configuring the instrument. Three access codes are used in the instrument: one for
instrument calibration (333), one for instrument configuration (444), and one to zero
adjust the instrument (222). These codes are not changeable and are required as input
whenever the customer presses the MODE button to access either the calibration routine
or the setup routine if the security feature is enabled.
If the security feature is enabled, the scr een shown in Figure 5 will be shown w hen you
press the MODE button. The security code has three numbers that are selectable one at a
time. Use the
key to accept the number. Then repeat the process for the next two numbers in the access
code. If you have selected a valid code the OCM will be directed to either the
calibration, the zero adjust, or the user setup mode depending on the access code that was
provided to the instrument. If the wrong access code is selected, the instrument will
return to the AUTO mode.
