GENERAL OPERATIONRONK ATS GENERAL OPERATIONThe ATS switch in combination with the controller module willallow for the automatic transfer of an electrical load to a standbypower source in the event of an over/under voltage or frequencycondition on any or all phases of the utility power supply.In the event of an over/under voltage or frequency condition ofutility power, the onboard controller sensing circuitry will beginthe initiation of the transfer process. Upon initial sensing of aloss of utility power, the transfer switch is specifically designedto allow an engine start time delay period (Parameter 502) toexpire before starting the generator. This engine start time delayis user-adjustable from the switch, preventing unnecessaryengine starts from a temporary loss of utility. In the event theutility source is not restored after the engine start time delay hasexpired, the remote contacts will close, sending a signal to thegenerator’s automatic start controller.While the transfer switch is in the generator position, thecontroller will constantly monitor the utility source voltageand frequency status. Once the utility source is restored, thetransfer switch will wait until the generator to utility time delay(Parameter 510) has expired before switching back to the utilityposition. All connected loads are transferred to the utility powersource.When connected loads are transferred back to the utility powersource, an engine cooldown period (Parameter 511) will beinitiated, allowing the generator to run in a no-load condition.This engine cooldown time delay is user-adjustable from thecontroller, allowing the generator to continue running for anadjustable period after the utility is restored.When the ATS controller senses that the generator has started,and is within acceptable limits, the transfer switch will wait untilthe utility to generator time delay (Parameter 503) has expiredbefore switching to the generator position. All connected loadswill be transferred to the generator power source.Display Scroll ButtonMain Status DisplayCommon Alarm IndicatorInfo ButtonS1 Breaker ControlSelect ModeRONK Automatic Transfer Switch Owner’s ManualS2 Breaker Control13

After ten minutes ofthe generator powering the load, the ATS will transfer the loadback to utility power. The generator will run through a cooldownperiod and then be shutdown.The 208V settings will result in a switch that will work in a 208V,3ph, Y system. On the Line side of the system, these settings willresult in an Under Voltage Return at 218V. On the Auxiliary side,the system will have an Under Voltage Trip at 179V, a LoadingVoltage of 187V, and an overvoltage trip of 230V.NOTE:DSE parameter setpoint represent Vø-ø/sqrt(3).To change the scheduler, configuration parameters 901 through905 can be modified.14RONK Automatic Transfer Switch Owner’s Manual
