Description

The oil & turbidity detector OR 52-7 can be used:

■ On board of marine vessels for monitoring the oily water separating equipment for bilge water

according to IMO Resolution MEPC. 107 (49) as 15 ppm oil content alarm.

Function

The measuring sensor is a photometric measuring device consisting of a light source (light emitter)
and a light receiver fitted with two photosensitive elements.

The constant light beam generated in the measuring sensor passes through the transparent liquid. Any
foreign matter which is not dissolved scatters the beam, with emulsified oils scattering the light mainly
in the forward direction. The intensity of the scattered light is converted into an electric current and then
used as measure of the degree of contamination.

The measuring transducer has the following functions:

■ Control of the measuring sensor and signal evaluation

■ Control of the purging valve

■ Limit ALARM 1 and ALARM 2

■ Analog actual value output 0/4 – 20 mA

■ ALARM 2 indicates a malfunction in the turbidity sensor

■ Indication of actual value / limits

■ Storage and indication of alarm, malfunction and status messages

■ Control of the bilge bypass via output ALARM 2

Installation

OR 52-7

Use the support and install the measuring sensor ORG 12 as close as possible to the separator in
order to keep the supply delay to a minimum. According to MEPC. 107 (49) in the event of an alarm
(oil content =/> 15 ppm) the contaminated water must be diverted from the separator to the bilge as
quickly as possible, i. e. within no more than 20 seconds.

Use a 10x1 mm copper or stainless steel pipe to connect the measuring sensor ORG 12/22 with the
sampling point of the separator and the clear water supply. The sampling point should be provided in a
vertical section of the separator outlet pipe so as to avoid any impairment caused by air bubbles.
In order to ensure that the arrangement for the extraction of samples gives a truly representative
sample make sure that the fluid flow always passes through the sensor under all operating conditions
and that any by-passing of the oil separator is prevented.

If it is not possible to provide the sampling point in a vertical pipe, a lateral arrangement in a horizontal
pipe is also possible.

For overboard pipes having an outside diameter of up to 75 mm a tee piece for the extraction of
samples can be used. If the size of the pipe exceeds 80 mm, make sure that the sampling arrange­ment extends approx. 25 % into the overboard line.

Install the vacuum breaker above the highest point of the oil separator.
Attach the measuring transducer ORT 7 to a stable vertical surface. If possible mount the indicator at

eye level for easy viewing and provide sufficient space for service and maintenance work.
The measuring transducer is designed for wall mounting. The distances between the fixing holes are

indicated on the back of the equipment.
To access the fixing holes undo the cover screws and open the cover.

Notice

Fig. 4 shows an example where the water will be run back to the ship‘s bilge in the event of an alarm

(oil content > 15 ppm) or auxiliary power failure.
With different limit settings alarm contact 1 can, for instance, be used for the first alarm and alarm

contact 2 for the main alarm.
For bilge water monitoring a pneumatic three-way valve can be controlled by the alarm contact 2 via a

solenoid valve. If the turbidity of the effluent is too high (alarm caused by ingress of oil or dirt particles
introduced into the system during start-up) the three-way valve will divert the contaminated water to
the bilge tank. The separation continues until the oil content falls below 15 ppm and the cleaned water
can be discharged overboard.

Data Storage

Memory Card

The memory card is on the CPU circuit board in the housing lid. Fig. 7. The design of the card ensures
that the recorded time, date, alarm, malfunction and status messages are stored for 18 months as
required by the IMO Resolution MEPC 107 (49).

Once the capacity limit of the card is reached, the oldest message will be overwritten, which means
that the card does not have to be exchanged.

The memory card is encoded with the serial number of the associated oil & turbidity detector OR 52-7
and, as a consequence, only this particular device can write data on the card. All other devices are
only able to read the data stored on the card.

Note

When replacing the oil & turbidity detector OR 52-7 make sure that the memory card
remains on board the ship because it contains the proof that the requirements regarding
oil separation as stipulated by the IMO Resolution were fulfilled.

To take the card out of the card holder unscrew the card locking piece &, Fig. 7.

Data indication

According to the IMO Resolution MEPC 107 (49) the time, date, alarm, malfunction and status
messages must be stored for 18 months. The measuring transducer features therefore a data logging
function.

The state of the equipment (Log MSG: Oil content, Alarm 2, Clear Water and Separator) and, in addition,
every change of state (State change: ON/OFF Alarm 2, geographic position, Clear Water and Separator)
are saved every hour.

Operating steps – see Fig. 8

1 To view the stored data in the log window press key  in the measurement window. If you

want to go back press key .

2 To enter the enquiry mode press key  or . Depending on the adjusted enquiry interval (dT) the

stored state messages (Log Msg) and changes (State Change) will be indicated.

Calibration

OR 52-7

According to the IMO Resolution MEPC 107 (49), section 4.2.11, the measuring accuracy of the 15 ppm
bilge alarm must be checked when the equipment is inspected in order to obtain the extension of the
period of validity of the IOPP certificate (5 years) as specified by the manufacturer.

For this inspection the measuring transducer ORG 12 must be exchanged.
Please order a replacement for the measuring transducer ORG 12 (stock code 389 427), indicating the

serial number, in good time before the IOPP certificate expires.
Before exchanging the measuring transducer undo the central screw of the connectors for the light

emitter/receiver and for the purging valve and detach the connectors.
Remove the measuring transducer and mount the replacement equipment.
Attach the connectors to the light emitter/receiver and the purging valve and tighten the central screw.
Repeat the commissioning procedure.

Maintenance

Cleaning the glass cylinder

1. Push the wiper of the cleaning device
2 or Malfunction may be triggered (depending on the time delay setting) and the amber LED is
flashing.

2. Return the wiper of the cleaning device
70 mm from the equipment).
The cleaning interval (e. g. once a week) depends on the amount of dirt deposits.

Replacing the drying cartridge

Replace drying cartridge when its content turns pink. Should this happen too often check the following
items for tight shut-off:

■ O-rings of light emitter

■ Cable glands of light emitter and light receiver

■ Gaskets of connectors and drying cartridge

Replacing the light emitter/receiver

1. Undo fixing screw and remove connector from light emitter/receiver.

2. Unscrew union nut (outside) of the light emitter/receiver tube and detach the emitter/receiver from
the body of the measuring transducer.

3. Replace the light emitter/receiver. Make sure that the locating pin of the emitter/receiver fits into
the groove of the light emitter/receiver.

4. Tighten external union nut.

5. Attach connector to light emitter/receiver and tighten the fixing screw.

6. Correct the zero point when the measuring transducer in programming mode (Parameter Value
Offset).

Please observe the notes on the spare parts kit “Light”.
