d) Time relayDuring the tests, adjust short-circuiting time relay to the higher value in order to avoidany undesirable short-circuiting.e) DosingFirst, test the starter with water only (without soda) and measure the variations of therotor voltage.‣ If the rotor voltage gets stabilized or does not decrease, stop the startingsequence within 5 seconds.Note the voltage value as:test without soda: Ur water =….Make sure that motor works properly. (ie: the motor is stopped, or runs then getsjammed or runs without speeding up)Switch off the power.Add some of the electrolyte preparation according to the following table:VectroStar R25 2 doses (50 ml) 25g of sodaVectroStar R65 4 doses (100 ml) 50g of sodaVectroStar R120 8 doses (200 ml) 100g of sodaVectroStar R200 16 doses (500 ml) 200g of sodaSwitch on the pump during 100 sec. (mixing of the bath).Switch on the power.Test the motor then repeat the procedure at : «Note Ur xg = …. » ….and so on, for sometimes.When following this procedure, the rotor voltage is getting lower. The aim is to get a rotorvoltage, lower than about 6% of Ur from the motor plate at the end of the end of thestarting sequence.When you hit the target, adjust the short-circuiting delay with a safety margin and withoutswitching on the power side.T (short-circuiting) = T (to go down to 6% of Ur) +5 sec.Check the tightening of the power cables.Secure the flow and recycling valves.Pour the bottle of electrolyte anti-evaporation oil.Close the fill-up hole and carefully replace the lid on the starter with its fastening belt.You are now ready to go !!!
