Hard Copy
When the Hard Copy routine is selected, the printer (connected to the MEGAMUX PLUS system
printer port), prints alarm messages stored in the alarm buffer and any additional alarm messages
as they occur. The following operating instructions are applicable to Lear Siegler Models ADM-
12 and ADM-12 Plus terminals. To print alarm messages, proceed as follows:
1.
Select the Hard Copy routine from the Alarm Scan menu.
2.
The screen displays TURN ON PRINTER. Turn the printer ON.
3.
Depress the Control, Shift and Aux Port keys simultaneously. Now press Return. All alarm
messages stored in the alarm buffer will be printed. New alarm messages will be printed as
they occur.
4.
To exit the routine, press the Aux Port and Control X key simultaneously. The screen re-
turns to the Alarm Scan menu.
Delete Displayed Alarms
The Delete Displayed Alarms routine clears all stored alarms in the MEGAMUX PLUS alarm
buffer. The routine is intended to be used after you have displayed or printed the stored alarms.
To successfully clear all alarms, you must first use the Screen Display routine to view alarm mes-
sages. If you do not display all messages, a message reports the number of undisplayed alarms
still in the alarm buffer:
14 UNDISPLAYED ALARM(S) NOT DELETED
When the Delete Displayed Alarms routine is selected, after viewing all alarms, the Alarm Scan
Menu remains on the screen. The buffer is cleared without any change in the display. The Screen
Display routine will determine if new alarm messages were generated after the clear operation
was accomplished.
Delete Inactive Alarms
The Delete Inactive Alarms routine clears all inactive alarms from the alarm buffer (viewed on
the alarm scan display). Inactive alarms are those alarm conditions that no longer exist, or have
been reported again by a new alarm message. If you select the screen display routine, the screen
reports an alarm deleted message, together with the date and time.
