AE11 Operating Procedures

The AE11 engine controller is programmable and it’s internal workings is more complex than the other AE series generators.

Auto Start Operation

This mode is activated by pressing the Auto pushbutton, see Figure 4-2. An LED indicator beside the button lights in Auto mode. The start sequence is initiated when the remote start input from the transfer switch or other device is activated. To prevent a false remote start, the Start Delay timer is initiated. If the Remote Start signal is removed during the Start Delay timer, the unit returns to stand−by. After the Start Delay, if the pre−heat output option is selected, the pre−heat timer is starts, and the corresponding auxiliary output (if configured) will energize.

After these delays, the Fuel Solenoid is energized, then one second later, the Starter Motor is engaged. The engine is cranked for a 10−second period. If the engine fails to start, the starter motor is disengaged for a 10−second rest period. Should this sequence continue beyond the 3 starting attempts, the start sequence will be terminated and Fail to Start fault will be illuminated.

When the engine starts, the starter motor is disengaged and locked out at 20 Hz measured at the Alternator output. (Rising oil pressure can also be used to disconnect the starter motor, however it cannot be used for under speed or over speed detection).

When the starter motor has disengaged, the Safety On timer starts. This timer is preset to 12 seconds and allows engine speed, Oil Pressure, High Engine Temperature, Under−speed, Charge Fail and Auxiliary fault inputs to stabilize without triggering a fault. Once the engine is running, the Warm Up timer starts (if selected). This allows the engine to stabilize before the load is switched on. After the Warm Up delay, the AC output is switched on to operate the load. When the Remote Start signal is removed, the Stop Delay timer is initiated. After which the Load Transfer output (if configured) is deactivated, and the Cool Down Period is initiated. After the Cool Down Period has elapsed, the Fuel Solenoid is de−energized, bringing the generator to a stop.

Manual Operation There is no “Start Delay” in Manual Run.

This mode is activated by pressing the Manual Run pushbutton, see Figure 4-2. If the pre−heat output option is selected, the pre−heat timer is starts, and the corresponding auxiliary output (if configured) will energize. After this delay, the Fuel Solenoid is energized, then one second later, the Starter Motor is engaged. The engine is cranked for a 10−second period. If the engine fails to start, the starter motor is disengaged for a 10−second rest period. Should this sequence continue beyond the 3 starting attempts, the start sequence will be terminated and Fail to Start fault will be illuminated. When the engine starts, the starter motor is disengaged and locked out at 20 Hz measured at the Alternator output. (Rising oil pressure can also be used to disconnect the starter motor, however it cannot be used for under speed or over speed detection).

When the starter motor has disengaged, the Safety On timer starts. This timer is preset to 12 seconds and allows engine speed, Oil Pressure, High Engine Temperature, Under−speed, Charge Fail and Auxiliary fault inputs to stabilize without triggering a fault. Once the engine is running, the Warm Up timer starts (if selected). This allows the engine to stabilize before the load is switched on. After the Warm Up delay, the AC output is switched on to operate the load. The generator will continue to run until the “Stop” or “Auto Start” mode is selected.

If Auto mode is selected, the Remote Stop Delay Timer starts. After this delay, the Fuel Solenoid is de−energized, to stop the generator.

Selecting Stop de−energizes the Fuel Solenoid is de−energized, to stop the generator.

Warnings and Shutdowns

Warnings

Warnings are used to warn the operator of a problem fault. Battery Charge Failure, if the module does not detect a voltage from engine mounted alternator, the lamp will illuminate. (Either 8 Volts or 16 Volts depending on the configuration of Nominal DC Voltage). Inputs 1 and 2 can be configured as warnings or shutdowns. The lamp will be illuminated when the input is active.

Shutdowns

Shutdowns are latching and stop the Generator. The alarm must be cleared, and the fault removed to reset the module. In the event of a shutdown the appropriate lamp is illuminated. The alarm condition must be corrected before a reset will take place. If the alarm condition remains it is not possible to reset the unit (except faults that occur during the “Safety On timer” period. These are delayed alarms, like oil pressure is low with the engine at rest).

Inputs 1 and 2 can be configured as warnings or shutdowns. The relevant lamp is illuminated when the input is active.
