FailedTests DeviceNet Limitorque Interface One or more of the following errors have been
detected during self-test of the DeviceNet
Limitorque Interface e.g.
- FLASH Checksum Error
- RAM Memory Test Error
Activated SMT Main Board Is_Active-Flag is TRUE
Deactivated SMT Main Board Is_Active-Flag is FALSE OR
EEPROM Checksum Error
Minor Fault SMT Main Board Conditions that can cause this event are e.g.
valve jam, overtemp, overtorque and phase loss.
This event is triggered if Attribute DI_Actuator_
Faults_1_Chan in Channel Object Class is ≠
0x00
Major Recoverable Fault SMT Main Board Conditions that can cause this event are e.g.
communication fault, power fault or Limiguard
fault of the SMT Main Board.
This event is triggered if Attribute DI_Actuator_
Faults_3_Chan in Channel Object Class is ≠
0x00
Major Unrecoverable Fault DeviceNet Limitorque Interface Internal Diagnostic Fault detected e.g.
- Receive Queue Overrun
- Transmit Queue Overrun
- CAN Controller Overrun
