Thomas & Betts Limitorque MX Device Net Field Unit manual DeviceNet Object Instance Attributes

Limitorque MX DeviceNet Field Unit  FCD LMENIM2328-00 – 11/05

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
