Channel 349 – Actuator Faults 1 (Index 109)
This channel, DI_ACTUATOR_FAULTS_1_CHAN, makes actuator faults available to DI function
blocks. The reported faults include:
• Valve jammed in motion due to a tripped torque switch.
• Valve was manually moved with the actuator handwheel.
• An over-torque condition while traveling.
• Loss of electrical phase.
• Thermal overload indicating the motor has overheated and the thermistor has opened.

Channel 350 – Actuator Faults 2 (Index 110)
This channel, DI_ACTUATOR_FAULTS_2_CHAN, makes actuator faults available to other function
blocks. The reported faults include:
• Valve jammed in motion due to a tripped torque switch.
• Valve was manually moved with the actuator handwheel.
• An over-torque condition occurred while traveling in the open direction.
• An over-torque condition occurred while traveling in the close direction.
• Loss of electrical phase at the motor.
• Thermal overload indicating the motor has overheated and the thermistor has opened; time is
required for the motor to cool and reset the thermistor.
