10-4 System Memory Errors [A.04 - *]
•
Code A04-01 - SYSTEM MEMORY ERROR / FLASH ROM WRITE ERROR
Communications error to internal MFC Unit Flash ROM during a WRITE attempt.
CAUSE:
1. If the controller is located in an electric or magnetic noise field.
2. Flash ROM IC chip has malfunctioned.
RECOVERY:
1. Verify that the controller is not located near any high voltage transient power sources. Relocate
as required and reinitialize the system.
2. Turn control power off to the unit for at least 5 seconds then re-apply power.
3. Replace controller.
•
Code A04-02 - SYSTEM MEMORY ERROR / FLASH ROM READ ERROR
Communications error to internal MFC Unit Flash ROM during a READ attempt.
CAUSE:
1. Corrupt memory data in the fieldbus configuration area
2. If the controller is located in an electric or magnetic noise field.
3. Flash ROM IC chip has malfunctioned.
RECOVERY:
1. If fieldbus interface is used, configure and download fieldbus configuration. Cycle Power.
2. Verify that the controller is not located near any high voltage transient power sources. Relocate
as required and reinitialize the system.
3. Turn control power off to the unit for at least 5 seconds then re-apply power.
4. Replace controller.
•
Code A04-03 - SYSTEM MEMORY ERROR / SERVO AMP FLASH ROM ERROR
Communications error to internal MFC Unit Servo Amp flash ROM.
CAUSE:
1. If the controller is located in an electric or magnetic noise field.
2. Flash ROM IC chip has malfunctioned.
RECOVERY:
1. Verify that the controller is not located near any high voltage transient power sources. Relocate
as required and reinitialize the system.
2. Turn control power off to the unit for at least 5 seconds then re-apply power.
3. Replace controller.
•
Code A04-04 - SYSTEM MEMORY ERROR / STORED DATA WRITE ERROR
An error occurred during a WRITE attempt to SDRAM saved data.
CAUSE:
1. If the controller is located in an electric or magnetic noise field.
2. SDRAM chip has malfunctioned.
RECOVERY:
1. Verify that the controller is not located near any high voltage transient power sources. Relocate
as required and reinitialize the system.
2. Turn control power off to the unit for at least 5 seconds then re-apply power.
3. Replace controller.
