System Schematic For kW Level OutputThe kW level output will be activated whenever the total power output of the generator exceed the setpoint P139. The kW level output is the connector contact 34 of the GSC+. This setpoint can be programmed from 0 to 110 percent of the rated power on the nameplate (setpoint P030). This setpoint can be programmed with a time delay from 0 to 120 seconds (setpoint P140). See System Operation, "Engine/Generator Programming OP5-0". Also, see System Operation, "Service Mode". Once the output is activated, the kW level output will be deactivated when the total power output of the generator drops below a programmed setpoint (setpoint P141). This setpoint is different from the activation setpoint. This setpoint can be programmed from 0 to 110 percent of the power rating on the nameplate of the generator. This setpoint can be programmed with a time delay from 0 to 120 seconds.When kW relay is disconnected from the GSC+, the voltage on the kW level output is approximately 5.0 DCV. When kW relay is connected to the GSC+, the voltage on the kW level output is approximately 0 volts. The kW level output is capable of drawing (sinking) approximately 100 mA. Documenting and troubleshooting any connections to this output is the responsibility of the customers and the dealers. The possible cause of a CID 0859 FMI 04 is a short to the "-battery" circuit of the kW level output.The GSC+ treats a CID 0859 FMI 04 as an alarm fault.Troubleshooting of this failure is straight forward. The FMI 04 defines
