Display Area Of Generator Set Control +P (GSC+P). (1) Dedicated shutdown indicators. (2) Spare fault indicators (Or synchronizing lights on the GSC+P). (3) Fault shutdown indicator. (4) Fault alarm indicator. (5) Upper display. (6) Lower display. (7) Keypad. | |
The GSC+P has five modes of operation. A brief description of each mode follows this paragraph. Refer to the individual topics for more detailed information.
Normal Mode - The GSC+P uses normal mode for the normal operation of the generator set. The operator can identify normal mode by observing the display area. When the GSC+P is in the normal mode, all the dedicated shutdown indicators are OFF. The fault shutdown indicator is OFF. The fault alarm indicator is OFF and "SERV" is NOT SHOWING on the upper display.
Alarm Mode - If there is an alarm fault, the GSC+P will automatically go into alarm mode in order to alert the operator of a non-critical fault. The operator can identify the Alarm Mode by observing the display area. When the GSC+P is in Alarm Mode, the fault alarm indicator is FLASHING. The fault code will be shown when the "Alarm Codes" Key is pressed.
Shutdown Mode - If there is a shutdown fault, the GSC+P will automatically go into shutdown mode in order to alert the operator of a critical fault. The operator can identify the shutdown mode by observing the display area. When the GSC+P is in shutdown mode, a dedicated shutdown indicator is FLASHING, or the fault shutdown indicator is FLASHING.
Service Mode - The GSC+P goes into Service Mode when the operator presses the "Service Mode" key that is located on the keypad. The operator can use Service Mode for the following purposes:
- Assist with troubleshooting diagnostic faults.
- Verify, calibrate or adjust the generator set functions.
- Satisfy special applications.
- Satisfy the needs of the customer.
The operator can identify service mode by observing the display area. When the generator set is in Service Mode, "SERV" is SHOWN on the upper display.
Note: Service Mode cannot be entered when the ECS is in the AUTO position.
Parallel Mode - The GSC+P uses Parallel Mode to synchronize the generator sets to other generator sets or to a utility bus. The GSC+P is in Parallel Mode whenever the Parallel Mode Switch is in AUTO, Semi-Auto, or Permissive positions. Parallel Mode is enabled in Normal Mode or Alarm Mode. Some alarm conditions may stop the process of Synchronization. For more information, refer to Systems Operation, "Paralleling Mode".
