I) PrincipleD – PARTICULAR CASES OF THE VECTROSTAR R200P & R200TThe VectroStar R200P & R200T have been designed on the same principle than the otherVectroStar R except that they use 2 or 3 reserve tanks and 2 or 3 start tanks instead of 1.Their conception corresponds to the need of an higher thermal absorption.However, they will only need one set of control devises (Time relay) and one shortcircuitingcontactor The VectroStar R200P includes a Master unit (a VectroStar R200) and a Slave unit (aVectroStar R200 without Time Relay and without Short-circuiting Contactor) electricallylinked together The VectroStar R200T includes a Master unit and 2 Slave units electrically linkedtogether.The principle is to get 2 or 3 times the same resistance in parallel so that all the deviceswill work in the same conditions to balance the power to be dissipated.II) Commissioninga) Basic settingsSee the appendix for the wirings.Fill up the reserve tanks with the same quantities of antifreeze (if required) andof water.b) The liquid flowsThe units in parallel must have exactly the same liquid flows.Therefore, the flow and recycling valves must be set at the same position.After having marked the electrodes holding plates for positioning, withdraw themand check without power that the filling-up of the starting tanks is simultaneous.At any time, level of liquid must be the same in all the units.When this has been checked, refit the electrodes holding plates.c) Soda dosingThe soda dosing will be done according to section C – II (pages 6-7) of thismanual.The only rule to remember is that if you add x doses of electrolyte in themaster unit, you must add x doses of electrolyte into each slave unit.
