Operating Procedures The engine−generator controller is designed to start and stop an engine from either a local<br />
mode “<strong>Manual</strong> Run” or remote mode “Auto Start”. When a start command is issued, the controller<br />
issues a run and crank output signal. The controller then monitors engine speed and when crank<br />
disconnect speed is reached, the crank signal is terminated. While the engine accelerates to<br />
normal speed, the controller continuously monitors the engines speed signal. Should the engine<br />
speed exceed the maximum predetermined setpoint, the Overspeed shutdown fault circuit will<br />
activate, terminating the run signal.<br />
In addition to Overspeed shutdown, other engine functions are also monitored and the engine will<br />
automatically stop for any shutdown fault. The engine will also stop, or when the remote start<br />
signal is removed or local Stop is pressed. The engine controller operation includes time delay<br />
circuits for normal operating conditions such as start delays, cool down and cranking periods.<br />
<strong>Manual</strong> Start/Stop All models.<br />
Push the <strong>Manual</strong> Run button to immediately initiate the engine crank cycle to start the engine<br />
and generate AC power. This mode does not require a start command from a remote device but<br />
operates immediately when the button is pushed. When pushed, the following happens:<br />
1. The Engine Crank cycle begins.<br />
2. When the engine starts and accelerates to nominal speed, the controllers speed sensor<br />
will terminate the Engine Crank cycle.<br />
<strong>Manual</strong>ly Stop the Generator−Set at anytime by simply pushing the “Stop” button. The<br />
controllers RUN output will be immediately terminated which will initiate the engine stop<br />
sequence.<br />
Automatic Start/Stop All models.<br />
Push the “Auto−Start” push−button. The following happens:<br />
1. The engine will automatically start upon activation of the remote start contact input. The<br />
remote device (transfer switch) initiates a start sequence when utility power fails.<br />
2. When the remote start signal is activated, the engine will start.<br />
3. The automatic stop sequence will be initiated by removal of the remote start signal.<br />
4. When the start signal is removed, a cool down delay function will be initiated.<br />
5. When the cool down time delay period expires (typically 5 minutes), the controllers<br />
RUN output will be immediately terminated which will initiate the engine to stop.<br />
<strong>Manual</strong>ly Stop the Generator−Set at anytime by simply pushing the “Stop” button. The<br />
controllers RUN output will be immediately terminated which will initiate the engine stop<br />
sequence.<br />
Automatic Fault Shutdown AE11 and AE25.<br />
When a fault circuit is programmed as a Shutdown, the engine will immediately stop when the<br />
fault is activated. A specific shutdown fault can be programmed with a definite time transient<br />
delay period that must expire before the shutdown is activated. The stop sequence will cause the<br />
controllers RUN output to be immediately terminated which will cause the engine to stop.<br />
A Warning lamp does not terminate generator set operation. It only warns that a condition<br />
exists. (alternator charge failure, etc.) but allows generator operation to continue.<br />
