H9 ASD Installation and Operation Manual
Trips/Faults
A
Trip
is an H9 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 14
are the
Faults
that may result in a
Trip
and the possible causes. When a
Trip
is
incurred the system displays the
Fault
screen. The
Fault
screen identifies the active
Fault
.
