Click Restart All Rectifiers.► To restart individual rectifiers In DCTools go to: Rectifiers. For each rectifier clear the Shutdown check box.The rectifier(s) will then resume normal operation. The SC100 will restart any shutdown rectifiers if: ac has failed, or more than one rectifier hasfailed, or the bus voltage is below the Low Load threshold, or Rectifier Shutdown is disabled. The SC100 will restart a shutdown rectifier if LBRS is active. See Load Based Rectifier Shutdownon page 24.Load Based Rectifier Shutdown Load Based Rectifier Shutdown is not available with APR48-3G, EPR48-3G, APR24-3G andCR48-3G rectifiers.If Load Based Rectifier Shutdown (LBRS) is enabled then the SC100 automatically shuts downrectifiers when the total load current is significantly less than the total rectifier capacity.This raises the average load on the remaining rectifiers which will then operate at a higherefficiency. This results in a decrease in system power consumption.The run time of all rectifiers is recorded and balanced to ensure even aging (and a balancednumber of rectifiers on each ac phase if rectifiers are assigned to phases).The SC100 will progressively restart rectifiers if the load increases. Rectifiers shut down by LBRS will have the yellow LED on. If N plus 0 rectifier redundancy is selected, then only sufficient rectifiers to supply the load will beon. If N plus 1 rectifier redundancy is selected, then one additional rectifier will always be on. The SC100 will automatically restart all rectifiers if ac supply has failed, or more than one rectifierhas failed, or Battery Test / Equalize / Fast Charge are active, or the bus voltage is below the LowLoad threshold.
