5 Explanatory Notes Scope of supply Measuring transducer ORT 7 Measuring sensor ORG 12 with 1 Solenoid valve 1 Drying cartridge (fitted) 1 Throttle (supplied but not fitted) 1 Accessory box: Content: 1 incandescent lamp (= light emitter) 1 Installation manual Description The oil & turbidity detector OR 52-7 can be used: n 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: n Control of the measuring sensor and signal evaluation, n Control of the purging valve, n Indication of limit ALARM 1 and ALARM 2, n Analog actual value output 0/4-20 ma, n Indication of malfunctions in measuring sensor and via ALARM 2, n Indication of actual value and limits, n Storage and indication of alarm, malfunction and status messages, n Control of the bilge bypass via output ALARM 2. 5

10 Installation OR 52-7 Use the support to 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 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 with 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 to a stable vertical surface.+ If possible, mount the indicator at eye level for easy viewing and provide sufficient withdrawal space for servicing and maintenance. 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

12 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 Connect PE with the earthing screw in the body. 6. Re-attach terminal strips. 7. Tighten the cable glands in order to seal the cable entry. Use the supplied sealing plugs to seal off any unused cable glands. 8. Close cover and tighten cover screws. Note n 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. n The terminal strips on the CPU board of the ORT 7 cannot be detached. n Strip off approx. 25 mm of the cable end insulation and screen of the connecting cables for the signal input of the separator ON/OFF and for the GPS input. Attention n The oil & turbidity detector has a max. power consumption of 50 VA. Please make sure that the power supply is rated for 100 VA. n To protect the output relay contacts fuse electric circuits with 2.5 A (slow.blow). n Provide connected contactors and actuators with RC combinations (in accordance with manufacturers specifications) in order to suppress interference. n Make sure that the disconnecting switch Fig. 4 is easily accessible and in the close proximity of the equipment (EN ). n 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

24 Data storage Memory Card The memory card is on the CPU circuit board in the housing lid. Fig. 8. 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 messages 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 exchanging the oil & turbiditiy 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 device w Fig. 8. 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 status of the equipment (Log Msg: Oil content, Alarm 2, Clear water and Separator) and, in addition, every change of status (Status change: ON/OFF alarm 2, geographic position, clear water and separator) are saved every hour. Operating steps - see Fig. 9 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 status messages (Log Msg) and changes (Status change) will be indicated. 3 If you want to change the interval press key + / - in the enquiry mode. The following interval options are available: all, day, week or month. 4 Enquiry interval (dt) dt: all = When pressing on the arrow key the next entry will be indicated. dt: day = When pressing on the arrow key the 24th entry will be indicated. dt: week = When pressing on the arrow key the 5 x 24 th entry will be indicated. dt: month = When pressing on the arrow key the 30 x 24 th entry will be indicated. 5 Press key or to view all status messages (Log Msg) and changes (status changes), depending on the ajdusted enquiry interval. 6 Press key or to view only the status changes, depending on the enquiry interval. 24
