254 ACE-tronics G9 ASD Installation and Operation Manual
Trips/Faults
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 15 are the Fa
ults that may result in a Trip and the possible causes. When a Trip is 
incurred the LCD screen shows the Fa
u
l
t screen and the LED screen displays the active Fault code.
