Code A03-05 - PREAMPLIFIER / WATCHDOG TIMER ERROR
Communications error between the tool preamplifier (torque transducer) and the controller.
CAUSE:
1. The tool cable is not connected or has lost connection during communication.
2. When the torque transducer, transducer cable or the controller malfunctions.
RECOVERY:
1. Verify that the tool cable is securely connected at both ends and free from cuts, abrasive wear or
kinks
2. Turn control power off to the unit for at least 5 minutes then re-start.
3. Exchange tool cable, tool and/or controller with known working units. Reinitialize the system after
each exchange to determine which component may have caused the failure (abnormal).
Replace the defective component
System Memory Errors [A.04 - *]
•
Code A04-01 - SYSTEM MEMORY ERROR / FLASH ROM WRITE ERROR
Communications error to internal HFC 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 minutes then re-apply power.
3. Replace controller.
•
Code A04-02 - SYSTEM MEMORY ERROR / FLASH ROM READ ERROR
Communications error to internal HFC 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 minutes then re-apply power.
4. Replace controller.
•
Code A04-03 - SYSTEM MEMORY ERROR / SERVO AMP FLASH ROM ERROR
Communications error to internal HFC 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 minutes then re-apply power.
3. Replace controller.
