8.2 INFORMATION
3. If no digital input is assigned to a contact converter, its status information will still be displayed along with
the contact converter number but the name will be blank.
This command displays the definition and the state of each digital output in the relay. This information is dis-
played three lines at a time. Use the arrow keys to scroll through the digital outputs (displayed in groups).
The Trip Outputs have the letter T in front of the output contact number. Alarm Contacts have the letter A in
front of the output contact number. The two Form C output contacts have the letter C in front of the number.
The Critical Alarm is just labeled CA.
If the DO status is shown as '0' it means it is OPEN. If it is '1', it is 'CLOSED'.
This category can be used to view event information logged when certain functions are performed by the relay.
Information displayed for each event consists of: Event number and its time of occurrence on the top line Date
of occurrence of event on the second line. Detailed event description on the third and fourth lines. The user
may use the ARROW keys to view the event information. The user can also enter an event number followed by
the [ENT] key to display the information for a specific event. An error message is displayed if the user enters
an invalid event number. Listed below is a list of the possible event messages available:
