SYMBOLIC ERROR MESSAGES
Symbolic error messages are caused by internal software or hardware errors and will have no obvious meaning to the
end user. If a symbolic message appears, cycle power on the controller to clear the fault. If the message repeats, call
Eurotherm Drives Customer Service.
ALARM PROCESS
The hexadecimal code for the first alarm is saved in HEALTH STORE. HEALTH STORE resets when the drive is
restarted. The alarm is also saved in LAST ALARM and stored until another fault trips out the drive or if the control
power is removed. All subsequent alarms are not displayed.
The first alarm as well as any subsequent alarms are stored in HEALTH WORD. HEALTH WORD is updated
continuously and shows the current condition of all alarms. As an alarm is cleared, HEALTH WORD reflects the new
condition of all remaining alarms.
You can monitor HEALTH WORD, HEALTH STORE, and LAST ALARM in the MMI under the ALARM STATUS
menu.
Alarm Status
This table lists the bit assignments of the MMI alarms in HEALTH WORD and HEALTH STORE in hexadecimal
format. The table also indicates whether you can override the alarm with the SETUP PARAMETERS:: INHIBIT
ALARMS menu and lists the delay time of each alarm, if any.
