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
Table 19
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.

Note:

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.
