Board includes test points, a plug-in connector, and is also fastened to the chassis (Refer to Item C, Figure 5). Bilge Alarm (02/02) Rev. 1.3 Page 1 II. WARNING separators must incorporate a suspended particle filter. ” The Sensing Module and the Indicating/Control Module are shipped with the Interconnecting Cable connected for reasons of convenience; however, electrical installation including routing of the Interconnecting Cable, power connections, calibration and servicing should only be done by qualified electricians and in accordance with applicable codes and regulations. Piping for the Sensing Module is arranged in the outlet line of the Oily-Water Filtering Equipment. Cleaned bilge water, up to 60 psi, flows through the module past optical windows where the measurement is made. A pre-focused incandescent light source provides a light beam which passes through the bilge water. A detector, placed at a 90° angle to the incident light beam, measures light scattered by the dispersed oil in the bilge water. An electrical output from the detector is transmitted through a cable to the Indicating/Control Module where it is processed. The measurement is displayed on the panel in “PPM”. Caution should be exercised when working on components inside the Indicating/Control Module while power is on. Coming in contact with live components may cause electrical shock or damage to equipment. If there is a possibility of voltage spikes or power surges to the instrument’s power supply module, an approved line suppressor is recommended. III. The digital display on the front panel shows 2 1/2 digits and can indicate readings up to 100 PPM accurately. Readings over 100 PPM are not reliable. An “ON/OFF” switch, for providing power to the Bilge Alarm, is also located on the panel. OPERATION Cleaned water from oily-water filtering equipment is continuously monitored. IV. INSTALLATION The Bilge Alarm measures and displays the concentration level of dispersed oil in the flowing stream of cleaned water. The instrument consists of a Sensing module and an Indicating/Control module. Oil content of the cleaned bilge is continuously shown on the Indicating/Control module’s digital display. An adjustable alarm set-point function, used to set the allowable oil concentration level, is located inside the Indicating/Control module. When the Sensing Module determines that the oil level exceeds the setpoint value, for longer than 15 seconds, a relay operates the lights on the display panel of the Indicating/Control Module. Green for “OVERBOARD” changes to red for “RECIRCULATE”. Simultaneously two sets of relay contacts activate independent alarm circuits. When the oil level in the effluent water is once more below the set-point value, the green lamp for “OVERBOARD” will glow and the red lamp for “RECIRCULATE” will shut off. The relay contacts will also deactivate. The above performance is contingent upon and consistent with the recommendations stated in the IMO Recommendations for Performance and Test Specifications for Oil Content Meters: “Non foaming detergents should not be used in the bilges for cleaning purposes, as the emulsifying effects of some compounds seriously affect the operation of the equipment. Non soluble suspended solids can give false high readings. The oil water Bilge Alarm (02/02) Rev. 1.3 Page 2 Install the Sensing Module using 1" piping after the Oily-Water Filtering Equipment. To permit use of the Bilge Alarm Calibration Kit, as well as a laboratory cleaning brush to clean the windows by brushing through when required, connect piping as shown in Figure #2. Sensor must be mounted vertically as shown in Figure 2, page 12, to allow the use of calibration kit Part No. 20098. Piping should be in accordance with 46 C.F.R. 56.01-IOD (U.S.Coast Guard). Connect Sensing Module to Indicating Control Module, as per Figures #3, #4, #7. Seal the cable entrance to the Sensing Module against the penetration of water vapor. Connect Power Source through fused switch to Terminals #6 and #7, in the Indicating/Control Module per Figures #3 and #4. Connect ground to Terminal #E9 per Figures #3 and #6. Selection of 115 volt or 230 volt operation can be made with the switch in the Indicating/ Control Module as shown in Figure #6, Item A. Use two 1/2 Amp fuse only for 120V; use two 1/4 Amp fuse for 240V. NOTE: Change both fuses for either mode of operation. V. ALARM CONNECTIONS Contacts for the Alarm Relay are located in the Indicating/ Control Module. These are “Dry” contacts with ratings of 5 amps at 120VAC or 28 VDC resistive. There are two sets of contacts which may be used to operate valves, sound alarms, etc. These are wired as follows refer to Figure #3 and #4. Note that the relay is de-energized in the Alarm condition. TB3 Set #1 Terminal #17 - Closed in the Alarm Condition Terminal #18 - Common Terminal #19 - Open in the Alarm Condition across terminals 10 (neg.) and 11 (pos.) in the Indicating/Control Module, (Refer to Figure #4). EXAMPLES: PPM (Oil in Water) 100 PPM 15 PPM 4. TB3 VI. Set #2 Terminal #20 - Closed in the Alarm Condition Terminal #21 - Common Terminal #22 - Open in the Alarm Condition Recorder Output Reading 5. 10 Volts 1.5 Volts Calibrate the Recorder Output to correct value by adjusting the Trim Pot marked REC on the Amplifier P.C. Board, (Refer to Item D, Figure #5). Adjust the Trim Pot marked DVM, on the same P.C. Board, to cause the Digital Display to read the correct value in PPM. START-UP NOTE: 1. 2. 3. 4. Turn on the Power Switch located on the Indicating/ Control Module. Allow the instrument to warm-up for approximately 30 minutes for stabilization. It is recommended that the power to the instrument be left on continuously except when servicing is required. Run clean oil-free water through the Sensing Module. Adjust the Zero Pot in the Indicating/Control Module (Item B, Figure #6) to cause Digital Display to indicate 00 PPM. NOTE: Negative readings on the Digital Display are indicated by a negative sign lighting up to the left of the Display Digits. When making adjustments do not over-adjust to negative values. The instrument has been factory calibrated in PPM. However, if it is desired to check calibration, the following procedure should be followed: 2. 3. Run clean oil-free water through the Sensing Module and adjust “Zero” control. Using an In-Line Calibration Holder, HF Part No. 20098, place a suitable calibration standard, equivalent to a known value of oil in water, in the Sensor. When conditions have stabilized, observe Recorder Output reading; it should read 10 Volts DC for 100 PPM and any proportional linear value between zero and 10 volts for lower values (see example below). Recorder output is obtained Bilge Alarm (02/02) Rev. 1.3 VIII. CALIBRATION CHECK This is a procedure used to check that the electronic function is still within the limits set by the Calibration Check Number. VII. CALIBRATION 1. 1. Whenever the value of the oil free water changes, it can be “Calibrated Out” by simply running a sample of the oil free water through the Sensing Module and adjusting the “ZERO” Pot in the Indicating/Control Module (Item B, Figure #6) to obtain a reading of “00” on the Digital Display. 2. Calibration should be checked after components have been replaced, i.e., P.C. Board, or Lamp, etc. 3. Whenever the instrument is re-calibrated a new “Cal Check” number should be obtained and recorded. See “Calibration Check” and follow steps 1 through 4. Page 3 1. Open the Indicating/Control Module. 2. Activate the CAL Check Switch (Item F, Figure 5, Spring Return) and note reading. 3. With the Cal Check Switch returned to its normal position and note reading. 4. Subtract the reading obtained in Step #3 above from that obtained in Step #2. 5. Compare the value obtained, which is the current Cal Check value, to the Cal Check number supplied with the instrument, which is affixed to the Indicating/Control Module Chassis. Should this current value vary by more than three (3) units from the original value, then the instrument should be re-calibrated. IX. 6) even though the water appears clean, or when the display shows a PPM count less that the true value. ISOLATION VALVES Isolation valves should be operated to shut-off flow from the Oily-Water Filter under each of the following conditions: A periodic cleaning routine should be established to preclude the system from remaining in the recirculation mode because of a fouled flow channel. The frequency of the cleaning operation should be determined on the basis of the type of fluids being processed and how often the flow channel becomes contaminated during initial system use. Procedure for cleaning is as follows: - Conducting service on the Sensing Module. - Calibration - Replacement of Sensing Module Otherwise always ensure that the valves are positioned to provide flow to the Sensing Module. X. 1. 2. 3. SETTING ALARM LEVEL Activate “Alarm Set” switch on the Amplifier P.C. Board in the Indicating/Control Module (Item E, Figure 5). While holding the “Alarm Set” switch “On” (spring return) the Digital Display will read the Alarm Set Value. 4. 5. XIII. REPLACING SOURCE LAMP ASSEMBLY Adjust the “Alarm” Trim Pot (Item G, Figure 5) while holding the Switch “On”, to cause the Digital Display to read desired Alarm Level. Release the “Alarm Set” Switch. The Alarm Relay will activate 15 seconds after the PPM Oil-in-Water content has constantly exceeded the Alarm Set value. The Source Lamp in the Sensing Module may burn out occasionally and require replacement. This failure will cause the Bilge Alarm to go into an Alarm Condition (Refer to Figure 7). 1. 2. XI. INDICATING LAMPS 3. Green light is ON, Red light is OFF, whenever Unit is operating under Normal Conditions. 4. Red Light is ON and Green Light is OFF, during Alarm Conditions. 5. The reading must remain over the alarm set value for 15 seconds to activate the alarm relay. 6. XII. CLEANING THE SENSING MODULE WINDOWS 7. 8. The Sensing Module through which the fluid flows and in which a light beam is projected to measure oil content in the effluent contains three precision glass windows. 9. 10. One indication that these windows may require cleaning is when the system enters the recirculation mode and remains in this mode even though a sample of the effluent from the Oily-Water Filter appears clean. Cleaning may also be required when oil-free water requires considerable adjustment on the Zero Pot (Item B, Figure Bilge Alarm (02/02) Rev. 1.3 Turn off the flow to the Sensing Module. Remove the clean-out plugs shown in Figure 2. Use a mild detergent on a laboratory cleaning brush and pass the brush through the Sensing Module flow channel several times.
