Channel 5 – Actuator Faults 2
The Channel 5 Discrete Input function block, 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.
