Operating basics
ALARM STATUS. D
isplays the name of the highest severity mainframe alarm
currently in effect. When no alarm is active, the message No Alarm is displayed.
Alarms must be enabled in the GPI ALARM SELECT submenu or the AGL7
ALARM SELECT submenu (when an AGL7 module is installed) before they will
appear in the A larm Status display after an alarm has been triggered.
If multiple alarms have been triggered, only the name of the highest severity
alarm is displayed. From low (1) to high (5) severity, the following alarm names
may appear:
1. No Alarm: No errors have been detected.
2. Genlock: Near Loss of Lock: The frequen cy of the genlock signal and the
internal reference signal have shifted considerably, and the TG8000 is near
loss of lock. If this message appears, check the frequency of the genlock
signal o
r the internal reference signal of the TG8000.
3. Genlock: Loss of Lock: The TG8000 cannot lock to the genlock signal.
4. Genlock: No Signal: A g enlock signal is not connected.
5. Fan Fault: The fan on the rear panel has stopped operating properly.
NOTE. The ALARM STATUS submenu does not update after you enter the
UTILITY menu. Therefore, if a new alarm occurs while you are looking at this
subm
enu, you will not see the new alarm until you exit and reenter the UTILITY
menu.
ALARM RESET. Resets all of the mainframe alarms that have been triggered.
Press the ENTER button to clear the triggered alarms. If the condition(s) that
triggered the alarm(s) still exists, the alarm(s) will come back immediately.
GPI ALARM OUTPUT. Enables or disables the GPI interface from triggering a
ground closure when an enabled GPI alarm is triggered. Use the left (◄) or right
(►) arrow button to enable or disable the GPI alarm output. Use the GPI ALARM
SELECT menu item to select which GPI alarms to enable.
GPI ALARM SELECT. Selects which GPI alarms are enabled or disabled. When
the GPI ALARM OUTPUT m enu selection is set to Enabled, the GPI interface
triggers a ground closure when an enabled GPI alarm is triggered. Select GPI
ALARM SELECT, and then press the ENTER button to access the G PI ALARM
SELECT submenu. (See page 2-41, GPI ALARM SELECT submenu.)
