Diagnostics

The 4320 includes the following diagnostics which can be accessed using the Field Communicator, AMS Wireless
Configurator, or AMS Device Manager.
D Cycle counter is shipped from factory with a high value. This alert is used with valves that have service
recommendations based on number of actuation cycles. Reset Accumulated Count is used to clear the
accumulated count value. This is typically done when maintenance to valve and/or actuator has been performed.
Refer to page 40 for additional information on Cycle Counter.
D Power status indicates the status of the power module voltage.
D Open or close stroke time indicates how long the on/off controller took to previously open or close the valve (not
available in snap-acting mode). Increased stroke time could suggest increased packing or bearing friction, loss of
motive-force, or trim clogging. Decreased stroke time could indicate the loss of process pressure or separated
linkage.
D Opened/high or closed/low dwell time indicates how much time has elapsed since the switch state last entered
opened/high or closed/low region. This can be used to determine when the valve last moved.
D Communications diagnostics allows you to review Network, Burst, Hardware Triggering, and Events information.
Refer to page 47 for additional information on communications diagnostics.
D Temperature extremes indicates the highest and lowest temperatures experienced by the device since it has
been placed in service.
D Active Fault Conditions indicate which fault conditions have initiated the fault state (On/Off Control only).
Accessing Diagnostics with the Field Communicator
Refer to figure 23 and 24 for the Field Communicator menu trees.
