PREFACEPRECAUTIONSThe CONVEX series underwater lights aredesigned to use the latest LED lightingtechnology.The thru-hull designed casings enable verysimple installation on the hull without makingany bigger holes through the hull under waterline.All the models are available in aluminiumbronze casings. The lighting are available inwhite, blue and green colors. All the modelsare designed with 6 power LEDs and suitablepower supply units. FEATURES Aluminium Bronze Casing6 Power LEDs DesignWhite, Blue or Green LightingTempered Glass Optical WindowHigh-Efficiency LensLow Power ConsumptionOver-Temperature ProtectionSimple InstallationRemote Control (optional) 3The underwater light has to be installed andused in accordance with the instructions ofthis manual only.The power supply has to be disconnectedbefore installation.The underwater light is recomended to beinstalled around 0.2 m below the waterlinefor the best illumination and to avoid overheating.Do not try to install or remove theunderwater light while the vessel is in thewater.The optical window has to be cleaned by asoft brush or cloth. Avoid using anyabrasive or chemical cleaner on the opticalwindow.Avoid installing the power supply unit inextremely hot places and near appliancesgenerating strong magnetic fields.Do turn power off immediately and referservicing to qualified service personnel ifthe underwater light does not operatenormallyfollowingtheoperatinginstructions.

INSTALLATIONThe underwater light kit consists of the following components: Underwater Light CONVEX MTH0680 Power Supply Unit MPS02800 Washer Fixing nut M24 Locking nut M24 with locking screw M8 and bonding screw M4 2 x cable gland M12 Operating Instructions with Declaration of Conformity and Warranty conditionsUnderwater Light CONVEX MTH0680The CONVEX MTH0680 has to be installed on a flat surface on the stern of the hull of the vessel.Do not try to install the underwater light while the vessel is in the water.When the installation is finished briefly test the underwater light prior to launching the vessel.The installation have to be realized by a qualified personnel.HULLSEALINGGROOVESWASHERLOCKINGSCREW M8LOCKINGNUT M24SCREWM24BONDINGSCREW M4SEALINGFIXING NUT M24Note: Avoid using the underwater light out of the water for more than 5 minutes.The underwater light is protected by a temperature sensor against over-heating. When thetemperature of the underwater light exceeds 60 C the power supply unit starts to reducethe current of the LEDs. If the temperature of the underwater light exceeds 90 C theunderwater light is automatically switched off.Hull preparationThe maximum hull thickness can be 90 mm.The underwater light is recomended to be installed around 0.2 m below the waterline for the bestillumination and to avoid over-heating.To fix the underwater light the diameter of a hole drilled through the hull has to be 24 mm.SealingBefore inserting the underwater light through the hole the sealant has to be used into the groovesand around the screw M24 in the rear surface of the light and has to be added to the exposed innerhole surface from the inside of the hull under the washer.The sealant can be on silicon basis but the best solution is two-component polymer sealant.6
FixingThe underwater light has to be inserted through the hole from outside of the hull and has to be fixedwith the fixing nut M24. Then the locking nut M24 (with locking screw M8 and bonding screw M4) hasto be fitted and locked with locking screw M8.Note: To install the underwater light on the steel hull it is highly recommended to use theoptional isolation board (not included) between the hull and underwater light casing toprevent galvanic corrosion.Note: Do not overtighten the nuts and screws as this can result in hull or underwater lightdamage.BondingThe underwater light has to be connected to the vessels bonding and cathodic protection using a pretinned wire a minimum of 8 AWG (8.36 mm2) with green insulation or green with a yellow stripe. Thewire has to be connected to the underwater light by the help of the bonding screw M4 located on thelocking nut M24.Note: It is highly recommended to paint the entire underwater casing exposed to the water withanti-foul paint. The optical window is protected with foil which has to be removed after anti-foulingprocess.Power Supply Unit MPS02800L2C2C4R16PWMCONTROLDC INK1SF3AREMOTECONTROL7DC OUTK4C7C1 C3L3L5U6R8C15L4L1 C14R4ASTELRT1MARINEC19K5C20R11R10K2R54R15D2R2 U3R6R13R12 C133R142LIGHTC61C5C16L7C17R9 D5The MPS06800 has to be installed near the underwater light inside of the vessel.Avoid the installation in extremely hot places and near appliances generating strong magnetic fields.An extension cable can be used in case of longer distance between the underwater light and thepower supply unit but with suitable length and thickness.The installation have to be realized by a qualified personnel.MPS02800
Note: The main DC power supply of the vessel has to be switched off before installation.Power supply connectionThe power supply has to be connected through the switch (not included) and protected by a fuse (notincluded) to the DC IN terminal-block connector with correct polarity. The power supply voltage has tobe from 10 - 30Vdc.A power supply unit of another underwater light can be connected to the DC OUT terminal-blockconnector.Note: Only one additional power supply unit of the same model number can be connected to theDC OUT terminal-block connector and suitable power supply cable should be used. Theappurtenant cap should be removed from the casing and enclosed cable gland M12 shouldbe inserted.Underwater light connectionThe underwater light has to be connected to the LIGHT terminal-block connector as described in thetable below:MPS02800terminal-block connectorLIGHT1234CONVEX MTH0680wire colourFUNCTIONBrownOrangeRedBlackLED1 LED1Temperature sensor Temperature sensor -Remote control connectionRemote control (optional) can be connected to the CONTROL terminal-block connector to turn-onand turn-off and to control the luminosity of the underwater light.To remotely turn-on and turn-off the underwater light the simple switch (not included) can be usedand connected to the CONTROL terminal-block connector by a 2-pole signal cable (not included).Note: To connect the 2-pole signal cable the appurtenant cap should be removed from the casingand enclosed cable gland M12 should be inserted.Note: If remote control is not used for normal operation the both contacts of CONTROL terminalblock connector has to be bridged.8

Convex obj non-convex domain. Introduction Generic Problem: min Q(x); s:t: x 2F; Q(x) convex, especially: convex quadratic F nonconvex Examples: F is a mixed-integer set F is constrained in a nasty way, e.g. x 1 3 sin(x 2) 2cos(x 3) 4 Bienstock, Michalka Columbia Convex obj non-convex domain.
Solution. We prove the rst part. The intersection of two convex sets is convex. There-fore if Sis a convex set, the intersection of Swith a line is convex. Conversely, suppose the intersection of Swith any line is convex. Take any two distinct points x1 and x2 2 S. The intersection of Swith the line through x1 and x2 is convex.

3 convex-convex n [DK85] convex-convex (n;lognp lognq) [DK90] INTERSECTION DETECTION OF CONVEX POLYGONS Perhaps the most easily understood example of how the structure of geometric objects can be exploited to yield an e cient intersection test is that of detecting the intersection of two convex polygons. There are a number of solutions to this .
Proof:Let us denote the set of all convex combinations of ppoints of Sby Cp(S). Then the set of all possible convex combinations of points of S is C(S) : [1 p 1Cp(S). If x2 C(S) then it is a convex com
