alarm mode alerts the operator when an alarm fault is occurring. An alarm fault is not critical but an alarm fault is potentially serious. An alarm fault precedes certain dedicated shutdown faults.When an alarm fault exists the GSC automatically activates alarm mode. The operator is alerted by the FLASHING fault alarm indicator. Press the "alarm codes" key in order to identify the alarm fault. A corresponding fault code is then shown on the upper display. This fault code can be an AL fault code, a SP fault code or a diagnostic fault code. For more information on fault codes, see Systems Operation, "Fault Description". When the GSC is in alarm mode the engine is able to start or the engine is able to run.The AL fault codes that are shown on the GSC indicate the current status of the generator set. The GSC does not show the AL fault codes after the fault has been corrected. However, diagnostic fault codes are logged in the GSC fault log for viewing later by service personnel.Note: A shutdown fault can be overridden by the operator by programming the shutdown fault to be an alarm fault. The corresponding indicator of the dedicated fault will be ON CONTINUOUSLY if the fault occurs after overriding the shutdown fault. The "ON CONTINUOUSLY" state means that the normal shutdown response has been overridden by the operator. The shutdown fault is treated as an alarm fault. A fault code is not shown on the upper display for the overridden shutdown faults. The dedicated shutdown indicator remains ON CONTINUOUSLY until the fault is corrected and the engine control switch is turned to the OFF/RESET position. The dedicated shutdown faults that can be overridden are low oil pressure and high coolant temperature. See Systems Operation, "Setpoint Programming OP5 (P03)". Also, see Systems Operation, "Shutdown Mode".Alarm faults do not have an immediate adverse effect on the generator set. However, the operator should investigate the cause of the alarm fault condition at the earliest opportunity. If the operation of the generator set is mandatory, then the procedure to start and stop is identical to normal mode. The GSC will respond to the operator input from the panel switches and the input from the engine sensors.Alarm Mode Sequence
An alarm fault occurs.
The GSC will detect the alarm fault. The GSC will FLASH the fault alarm indicator. The GSC does not change the status or the operation of the generator set.
Pressing the alarm codes key causes the upper display to show a corresponding fault code.
Correct the alarm fault. See Testing and Adjusting, "Fault Identification".
After the alarm fault has been corrected, the GSC turns OFF the fault alarm indicator and the GSC removes the fault code from the upper display. The GSC now returns to normal mode.
