Basic Principle ALARM lamp WATER that has electrolytic substancs like salt dis- solved in it such as ocean WATER conducts electricty, in other words,flows an electric current. More Battery specically, when electrodes are placed in ocan WATER in a beaker and connected and are connected to the battery and light bulb,the light bulb,lights up as show basic principle of the WATER Seawater in the Vessel INGRESS ALARM SYSTEM is that when electrodes con- tact with oceam WATER ,the lamp and buzzer issue the super EYE WATER INGRESS ALARM sys- Electric tem is based on this simple principle.

6 Current The electrodes contact sea WATER ,then electric electrode A electrode B current run through sea WATER and the light bulb Fig-1 is lit. Featues of super . Detection Circuit The electrorodes of the super EYE detector have EYE detector Wiring a feature of configuration of connecting the wir- ing for detection circuit and wiring for checkup Checkup Circuit Checkup Circuit circuit,as show in Wiring Wiring The part that detects duribg ocean WATER INGRESS is the wiring for detection circuit. By connecting the wiring for checkup circuit,the sys- Insulator tem error checkup is be carried out from a distant electrode A electrode B location such as the Wheelhouse. The electrode consist of corrosive resistant metal Fig-2 such as pratinum plated titanum plus side and minus side stainless steel.

7 Operation of the WATER INGRESS detect mode:The relay SYSTEM is super EYE checking WATER seawater rises up to WATER INGRESS Wheel house ALARM SYSTEM the detecting level,electric current live through the white arrow, and ALARM SYSTEM in Wheel- +. _ Relay house is ringing. Malfunction detect mode:Push the test switch on,then electric current live the black arrow. Test switch The relay SYSTEM activates and informs that Intrinsic safe barrier electoric circuit is normal any part of electric circuit is broken,electric current of black arrow is shutdown and the relay SYSTEM informs operator can know the WATER INGRESS ALARM SYSTEM failure. The super EYE WATER INGRESS ALARM SYS- Insulator TEM is operating to check those two detect modes Detecting Level every time.

Explosion-Proof Non-Intrinsically safe cir- cuit SYSTEM is suitable to make up Intrinsically Safe SYSTEM as show Fig-4. Fuse Fig-4 is the basic structure of the Zener barrier to make up Intrinsically safe SYSTEM . Normally,electric current run through white ar- row . If electric current is over the rated voltage, the current run through black arrow and block to run in Intrinsically safe cir- Zener Resistance Daiode cuit side. Intrinsically safe circuit Fig-4. SYSTEM Error The super EYE WATER INGRESS ALARM . Dtection Circuit Detect circuit of the PLC Pulse out circuit of the PLC SYSTEM has the automatic maltunction check func- tion as Fig-5.

9 LED The PLC makes cyclic ON-OFF pulse into LED. The transistor in the photo coupler is ON at the Transistor Photo- cyclic pulse on and is OFF at the cyclic pulse off. coupler The detect circuit of the PLC recognizes cycic pulse condition that is Malfunction detect mode or Wa- ter INGRESS detect mode. Zener At the cyclic pulse on(malfunction detect mode), Zener Barrier Barrier electoric currenet runs through black arrow . as show Fig-5. + _ + At the monent,PLC can detect the SYSTEM mal- function such as breaking of wire or disconnec- tion of wire and the PLC makes the SYSTEM mal- function ALARM . At the cyclic pulse off( WATER INGRESS detect mode), electrode A electrode B electric current do not run because the transistor isoff.

10 If WATER INGRESS occurs then eloectric current runs Fig-5 through white arrow as show Fig-5. The PLC can recognize WATER INGRESS and makes WATER INGRESS ALARM . 5.
