200 Q9 ASD Installation and Operation Manual
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 terminates the ASD output and disables the ASD system from processing a
Run command in the event that the ASD or a subsystem of the ASD is malfunctioning.
Listed in Table 12 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 or the first of
several until all cleared.
Note: See FC90 of the Q9 ASD for the Communications Error Code number of the active
fault.
The operating conditions at the time of the trip may be used to help determine the cause of the trip. Listed
below are operating conditions that may be used to assist the operator in correcting the problem or that the
ASD operator should be prepared to discuss when contacting Toshiba’s Customer Support for assistance.
