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. 4

Explanatory Notes Scope of supply Measuring transducer ORT 7 Measuring sensor ORG 12 with 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 5

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. 10

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.

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. 13

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.

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. 26

Maintenance Cleaning the glass cylinder 1. Push the wiper of the cleaning device 4 Fig. 5 up and down. When doing so Alarm 1 and/or Alarm 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 4 to its initial position (the plunger protrudes approx. 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: n O-rings of light emitter n Cable glands of light emitter and light receiver n 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. Attention Do not open the measuring transducer! Replacing the equipment fuse 1. Open the housing lid of the measuring transducer. Observe the warning note! 2. Turn the fuse carrier to the left and take it off. 3. Replace the equipment fuse. 4. Fit fuse carrier in place and turn it to the right. Close housing lid. 27
