5 OPERATION
5.1 DWELL Key
DWELL is used to enter the Dwell Time configuration
menu and to enter other menus. A momentary push
will enter the Dwell Time menu. Holding DWELL for
over one second will enter the program mode.
5.2 SKIP/clr Key
SKIP/clr has two uses. The first use is to program
which cameras will be in the switching sequence. This
key toggles the displayed camera in or out of the
sequence. An X will be lit to the left of the selected
camera number if it is excluded from the sequence.
Pressing
SKIP/clr while a sequence is running
immediately removes the camera from the sequence
and advances to the next camera. An alarm closure on
a skipped camera calls up that camera. This key also
clears the displayed camera's alarm display. The
cleared camera is not called up again until the alarm
closure occurs again for that camera.
5.3 ALARM Key
ALARM toggles the alarm function on and off.
When the Alarm is on:
• The alarm indicator LED is lit and the notation
MA (Monitor Armed) appears on the status line
(appears only on Monitor B for the
LTC 5108 Series).
• The switcher responds to all incoming alarms.
During the alarm period, the word ALARM
flashes on the status line, and the alarm LED
flashes.
When the Alarm is off:
• The alarm indicator LED is not lit and no MA
notation is present on the status line.
When the alarm function is off, the switcher will not
react to incoming alarms at that moment.
5.4 RUN/next Key
When multiple alarm call ups are present, RUN/next
sequences to the next triggered camera. If no alarm
call-ups are present and a hold is present, then the key
removes that hold. Lastly, if there are no "holds" or
alarm call ups, then by momentarily pressing the key,
the sequence can be immediately advanced to the next
camera input, or by continuously pressing the key, the
sequence will rapidly sequence. The
RUN/next LED
lights whenever switchers are sequencing, and goes out
whenever a HOLD is issued.
5.5 Numeric Channel Keys
These keys will issue a hold on their respective camera
inputs. The monitor (only Monitor B for the LTC 5108
Series) will stop sequencing (or BLANKING in the
BLANKING mode) and display that camera's video
until either:
A. Another Numeric Channel key is pressed, or
B. The RUN/next key is pressed, or
C. An alarm call up occurs on another camera.
If the Channel key is held down, the display of any
cameras currently in an alarm condition can be
overridden.
