250 H9 ASD Installation and Operation Manual
Trips/Faults

A Trip is a H9 ASD response to a Fault (though, Fault and Trip are sometimes used interchangeably). A

Trip is a safety fe at u r e th at disables the ASD system in the ev en t th a t a subsystem of the ASD is

malfunctioning or a parameter setting has been exceeded.

Listed in Table 1 4 are the Faul ts that may result in a Trip and the possible causes. When a Trip is

incurred the system display s th e Fault screen. Th e Fault screen identifies the active Fault.

A more user-friendly indication of the active Fault will be displayed at the LCD screen.
