Trips/Faults - Toshiba 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
incurred the system displays the Fault screen. The Fault screen identifies the active Fault.
