Alarms, Trips, and Troubleshooting
This section lists the available User Notification codes of the EOI display and provides information that
assists the user in the event that an Alarm or Fault is incurred.
The User Notification codes are displayed as an indication that a system function or system condition is
active (i.e., ATN and DBON); they are not error conditions. The code is displayed on the EOI for the
duration of the activation.
An Alarm is an indication that a Fault is imminent if existing operating conditions continue unchanged.
An Alarm may be associated with an output terminal to notify the operator of the condition remotely,
close a contact, or engage a brake. At the least, an Alarm will cause an alarm code to appear on the EOI
display.

ASD.
In the event that the condition that caused the Alarm does not return to its normal operating level within a
specified time, the ASD Faults and a Trip is incurred. (Fault and Trip are sometimes used
interchangeably). A Trip is the result of a Fault and serves as a safety feature that disables the ASD
system and removes the three-phase power from the motor in the event that a subsystem of the ASD is
malfunctioning or one or more of the variables listed below exceeds its normal range (time and/or
magnitude):
• Current,
• Voltage,
• Speed,
• Temperature,
• Torque, or
• Load.
See
Table 14 on pg. 192
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 the TIC Customer Support Center for
assistance.
• What is the ASD/Motor size?
• What is the CPU version and revision level?
• What is the EOI version?
• Is this a new installation?
• What trip information is displayed?
• Has the system ever worked properly and what are the recent modifications (if any)?
• Does the ASD trip when accelerating, running, decelerating, or when not running?
• Does the ASD reach the commanded frequency?
• Does the ASD trip with an unloaded motor?
• Does the ASD trip without the motor attached?
