Trips/Faults
If a user setting or a WX9 ASD parameter has been exceeded, or if a data transfer function produces an
unexpected result, a condition that is referred to as a Fault is incurred. A Trip is a WX9 ASD response to
a Fault (though Fault and Trip are sometimes used interchangeably). A Trip is a safety feature that
disables the ASD system in the event that a subsystem of the ASD is malfunctioning or a parameter
setting has been exceeded.

incurred, the system displays the Fault screen. The Fault screen identifies the active Fault.
Note:
An improper WX9 ASD setup may cause some trips — reset the ASD to the factory
default settings before pursuing a systemic malfunction (Program

Note: The event that caused the Trip(s) must be corrected or the monitored value must decrease to less than the
threshold value required to cause the Trip to allow for a Reset to be recognized. In the event of multiple
active Trips, the Trip displayed will remain until all Faults are corrected and all Trips are cleared.
