No Load Test

To allow a timed No Load Test of the engine/generator set while using the AMF control application, a digital input contact from an external timer must be programmed for NO LOAD Test The 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 may be initiated by closing an external exercise timer contact to the programmed digital input for No Load Test.

2.After the external exercise timer contact closes, the engine will start and come-up to normal operating speed and voltage. The controller will issue an alarm of a No Load Test condition. The connected transfer switch will remain on the utility and the generator will not transfer on load. Note: should the utility supply fail, the generator will automatically transfer on load.

3.The engine will continue to run as long as the external exercise timer contact remains closed.

4.After the external exercise timer contact opens, the engine will continue to run for its cool 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 many analog 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 Faults

Overspeed Shutdown	Overspeed Shutdown is initiated when the engine's speed has increased above the overspeed setpoint. The overspeed fault
	circuit is internally programmed as a latching shutdown fault. The overspeed shutdown fault circuit is programmable for the
	percentage of nominal engine speed (i.e. overspeed setpoint) and for the transient time delay period. The programming
	prompts 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 2
Alarm/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. The
	overcrank 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 other
	position (ON the keypad). This fault is internally programmed as a non latching alarm. In the main programming loop, this
	alarm 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 remote
Digital 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 label
	description as stored in the controller's non-volatile memory.
	Factory settings have four standard digital faults as follows:
	Fault	Fault	Digital Inputs
	Name	Action	Terminal #
	Low Oil Pressure	Shutdown	1
	High Engine Temperature	Shutdown	2
	Battery Charger Input Fail	Alarm	3
	Low Fuel Level	Alarm	4

The following is a list of all digital faults:
High Bearing Temp	Failed To Sync	Reverse Power	Bat Charger Input Fail
High Cooler Vibration	Low Fuel Press	Fail To Sync	Bat Chrg Trouble
High Engine Temp	Low Engine Temp	Vent Damper Fail	Bat Charger Fail
High Engine Vibration	Low Oil Pressure	Gen Breaker Open	DC Fail
High Fuel Level	Low Fuel Level	Ground Fault	Breaker Tripped
High Oil Level	Low Oil Level	No Load Test	Basin Rupture
High Oil Temp	Fuel Leak	ATS In Bypass
High Winding Temp	Low Fuel Press	Remote Emerg. Stop
*Highintkmanftemp	Low Coolant Level	Air Damper Tripped
