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.
