It is advisable to check once or twice a year:E – MAINTENANCE• The bath level in the electrolyte reserve tank. (If it is too low, add water only)• The tightening of power cables and control connections.• The state of electric gear.• The starting quality.- IF the starting time becomes too long or if there is a problem when the shortcircuitingcontactor is energised : - Add soda in the starter tank(for R200P and R200T, add the samequantity of soda in the slave than the master)To check the state of the complete starter cyclestarters types: VECTROSTAR R25, R65,R120 and R2001. Put the power off and disconnect the rotor cables.2. Remove the contactor copper bars and lift up the electrode-holding plate.3. Check the state of each electrodes, each electrodes must be cleaned and brushed ifnecessary.4. Check that the Flow and Recycling valves are set at the maximum.5. With the starting tank opened, put the 230V on the control terminals on the master.6. The pumps must be energised, if not, control the fuses and the pump motor.7. When the 230V is applied, check that the level of the liquid is rising progressively in 17s.If necessary, adjust the setting of the Flow valve.8. When the complete cycle has been checked (pumping and short-circuiting phase), refitthe electrodes holding plate.To check the state of the complete starter cyclestarters types: VECTROSTAR R200 T and R200 TReminder : The R200 P uses 2 tanks in parallel and the R200 T, 3 tanks.Each R200 P and R200 T includes a master tank (which contains the short- circuited contactor and the startup timer) and 1 or 2 slaves tanks (which are wired to the master unit). Each tank is equipped with a pump(230V/50Hz/0.550W/3000rpm).1. Put the power off and disconnect the rotor cables (connected to the master).2. Remove the contactor copper bars and lift up the electrode-holding plates.3. Check the state of each electrodes, each electrodes must be cleaned and brushed ifnecessary.4. Check that the Flow and Recycling valves are set at the same position on the masterand the slave(s).5. With the starting tanks opened, put the 230V on the control terminals on the master (theslave must be connected to the master via the control terminals to supply also the slavepump at the same time).6. The pumps must be energised, if not, control the fuses and the pump motors.7. When the 230V is applied, check that the level of the liquid is rising progressively at thesame time in all starting tanks. The standard filling up time is ∼17s. If necessary, adjustthe setting of the Flow valves.8. When the complete cycle has been checked (pumping and short-circuiting phase), refitthe electrodes holding plates.
