Chapter 3: Configuration and Operation
Alarm Control
The combination of the switch priority parameter settings, adjustable alarm
switch levels, and SQM smart alarms on the subdevice of the ACO6800
+
module provides flexible automatic and manual switch control. In the case of
the SQM smart alarms, you can individually adjust the severity and trigger/clear
duration for each alarm type (for more information, see
). The following tables offer two sample scenarios.
Note
By default, all alarms are set to a disabled state. To configure a device to
switch using alarms as a trigger, first enable alarms in the sub-device.
Failure of Auto/Manual switchover
If your auto/manual switchover does not work as expected, confirm that the
following parameters have been configured correctly:
•
Group (A/B) GPI Input_(1-3)
should confirm the GPI Input condition.
•
Group A
or
Group B Manual Switch
should confirm the expected setting.
•
Group A
or
Group B Switch (High/Medium/Low) Priority
should
display the sort of logic seen in
.
•
Group A
or
Group B Alarm Switch Level
should
confirm the triggered
level.
Confirm that the configurable portions of sub-device alarms match your
expectations. (This includes Enable/Disable, Alarm Priority, Trigger Time, and
Clear Time.)
For ACO6800
+
ISCST modules, ensure that the
Video Standard
and
Operation Standard
parameters have the same setting. The
Still Image Mode
parameter must be set to
Auto
, and the
Force Freeze
and
Force Black
parameters must be set to
Off
.
