Operation 4‐17MN2408No Load TestTo allow a timed No Load Test of the engine/generator set while using the AMF controlapplication, a digital input contact from an external timer must be programmed for NO LOAD TestThe sequence of operation for a No Load Test condition is as follows:1. With the utility supply normal and the generator stopped, a no load test sequence maybe initiated by closing an external exercise timer contact to the programmed digitalinput for No Load Test.2. After the external exercise timer contact closes, the engine will start and come-up tonormal operating speed and voltage. The controller will issue an alarm of a No LoadTest condition. The connected transfer switch will remain on the utility and thegenerator will not transfer on load. Note: should the utility supply fail, the generator willautomatically transfer on load.3. The engine will continue to run as long as the external exercise timer contact remainsclosed.4. After the external exercise timer contact opens, the engine will continue to run for itscool down time as programmed, then it will automatically stop.Standard Faults When a fault occurs, information about the fault is displayed. The engine controller has manyanalog and digital inputs for monitoring and control operations. Three types of faults are used:1. Internal Faults are derived from a combination of digital and analog inputs.2. Digital Input Faults are initiated from external contact inputs.3. Analog Input Faults are initiated from external analog signal inputs.Figure 4‐15 shows how the controller inputs and outputs are organized.A description of each is provided.Internal FaultsOverspeed Shutdown Overspeed Shutdown is initiated when the engine's speed has increased above the overspeed setpoint. The overspeed faultcircuit is internally programmed as a latching shutdown fault. The overspeed shutdown fault circuit is programmable for thepercentage of nominal engine speed (i.e. overspeed setpoint) and for the transient time delay period. The programmingprompts for overspeed are located in the main menu programming loop.Loss of Speed Loss Of Speed is initiated when the engine's speed sensing circuit does not detect a speed signal for a period more than 2Alarm/Shutdown seconds following a run signal. The loss of speed fault may be user programmed as a latching shutdown fault or alarm only.The programming prompts for loss of speed are located in the main menu programming loop.Overcrank Shutdown Overcrank Shutdown is initiated when the engine fails to start after the selected crank time or number of crank cycles. Theovercrank fault circuit is internally programmed as a latching shutdown fault and is not user programmable.Switch not in AUTO Switch not in AUTO is initiated when the controller's operating mode switch is changed from the auto position to any otherposition (ON the keypad). This fault is internally programmed as a non latching alarm. In the main programming loop, thisalarm may be user programmed to initiate the common fail output relay.Digital Input Faults Four digital faults are provided and these are user programmable. Each digital fault input circuit is activated by a remoteDigital Inputs (N/O or N/C) sensing contact that is external to the controller. Each digital fault input circuit may be programmed with a unique fault labeldescription as stored in the controller's non-volatile memory.Factory settings have four standard digital faults as follows:FaultNameFaultActionDigital InputsTerminal #Low Oil Pressure Shutdown 1High Engine Temperature Shutdown 2Battery Charger Input Fail Alarm 3Low Fuel Level Alarm 4The following is a list of all digital faults:High Bearing Temp Failed To Sync Reverse Power Bat Charger Input FailHigh Cooler Vibration Low Fuel Press Fail To Sync Bat Chrg TroubleHigh Engine Temp Low Engine Temp Vent Damper Fail Bat Charger FailHigh Engine Vibration Low Oil Pressure Gen Breaker Open DC FailHigh Fuel Level Low Fuel Level Ground Fault Breaker TrippedHigh Oil Level Low Oil Level No Load Test Basin RuptureHigh Oil Temp Fuel Leak ATS In BypassHigh Winding Temp Low Fuel Press Remote Emerg.
