Important Notes
Usage for the intended purpose
The GESTRA Turbiscope OR 52-7 is designed for the continuous monitoring and detection of oil
contamination of water and used in conjunction with oily water separators as 15 ppm bilge alarm.
The equipment meets the requirements of the International Maritime Organization (IMO) for bilge alarm
monitors, MEPC. 107 (49).
Safety note
The equipment must only be installed and commissioned by qualified and competent staff.
Retrofitting and maintenance work must only be performed by qualified staff who – through adequate
training – have achieved a recognised level of competence.
Danger
The solenoid of the solenoid valve Clw can reach up to 80 °C during operation.
The terminal strips of the measuring transducer ORT 7 can be live during operation.
This presents the risk of electric shock.
Cut off power supply before mounting, removing or connecting the terminal strips.

1 Solenoid valve
1 Drying cartridge (fitted)
1 Light emitter (supplied but not fitted)
1 Spare gasket kit
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.

Electrical Connection
Measuring transducer ORT 7
1. Undo cover screws and open cover.
2. Detach all three-pole terminal strips from the base board and pull connecting lines through cable
glands.
3. Mark connecting lines: “Mains”, “Alarm 1”, “Alarm 2”, “Light emitter” and “Light receiver”.
4. Connect all terminal strips in accordance with the wiring diagram. Connect screens only to ORT 7.
5. Connect PE with the earthing screw in the housing.
6. Re-attach terminal strips.
7. Tighten the cable glands in order to seal the cable entry. Use the supplied sealings plugs to seal off
any unused cable glands.
8. Close housing lid and tighten cover screws.
Note
■ The light emitter/receiver and the purging valve are fitted with a 4 m long connecting
cable and only have to be connected to the measuring transducer.
■ The terminal strips on the CPU board of the ORT 7 cannot be detached.
■ Strip off approx. 25 mm of the cable insulation coating and screen of the connecting
cables for the signal input of the separator ON/OFF and for the GPS input.
Attention
■ The oil & turbidity detector has a power consumption of max. 50 VA. Please make sure
that the power supply is rated for 100 VA.
■ To protect the output relay contacts fuse electric circuits with 2.5 A (slow-blow).
■ Provide connected contactors and actuators with RC combinations (in accordance with
manufacturers’ specifications) in order to suppress interferences.
■ Make sure that the disconnecting switch (Fig. 4) is easily accessible and in the close
proximity of the equipment (EN 61010-1).
■ Mark respective switch as disconnecting device for the measuring transducer.
This switch can be dispensed with if the control cabinets are upstream of the equipment
and fitted with a disconnector for the measuring transducer.
Tools
■ Screwdriver for cross-recess screws, size 1 and 2.
■ Screwdriver for slotted screws, size 2.5, completely insulated to VDE 0680
■ Conductor end sleeve pliers
■ Insulation stripper
