Operation Setting the Exercise Timer This generator is equipped with a configurable exercise timer. Configuration can be performed directly at the control panel or though the Mobile Link® application. There are two settings for the exercise timer: Day/Time: Generator will start and exercise for period defined, on day of week and at time of day specified. During this exercise period, unit runs for approximately five minutes and then shuts down.
Operation 7. Set generator MLCB (generator disconnect) to ON (CLOSED). Standby power source now powers loads. Transfer to Utility Power Source Shut down generator and transfer to utility source after utility power has been restored. Proceed as follows to manually transfer to utility power and shut down generator: 1. Set generator MLCB (generator disconnect) to OFF (OPEN). 2. Run engine for one minute at no-load to stabilize internal temperature. 3. Press OFF button on control panel. Engine will shut down.
Operation Load Transfer The transfer of load when generator is running is dependent upon operating mode. Shutting Generator Down While Under Load or During a Utility Outage DANGER Automatic start-up. Disconnect utility power and render unit inoperable before working on unit. Failure to do so will result in death or serious injury. (000191) IMPORTANT NOTE: To avoid equipment damage, follow these steps, in order, during utility outages.
