Trips
A Trip is an 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.
Listed in
are Faults that may be displayed
at the EOI and the possible causes. When a Trip is
incurred, the system displays the Fault screen. The
Fault screen displays the active Fault.
Note:
See FC90 of the Q9 Plus ASD for the
communications error code number of
the active fault
.

Possible Cause
Note: The event that caused the trip(s) must be corrected or 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
cleared.
