Rig Check
In Sensor3 racks with Advanced Features (see
Advanced Features (AF)
on
page 6
) you can record a
special preset called Rig Check, which includes both circuit levels and the amount of load (current)
expected on each circuit.
Once recorded, the Rig Check can be played back, either from the CEM3 face panel or remotely, and
the CEM3 will post
load high
,
load low
, or
no load
messages based on how the load of the circuit has
changed since you recorded the Rig Check preset. These messages will be available on the CEM3
display or on a connected console that monitors AF feedback.
You can record, run, and clear a rig check on the Test menu (see
Test
on
page 12
).
Spaces
Spaces are logical divisions within a system (such as different rooms) that isolate station control (preset
and sequence control) to the defined group of controllable outputs in that division. CEM3 supports
separation of its controllable circuits into spaces.
Station Functions
Presets can be played back from preset stations in the system.
• Press a preset station button to activate a preset.
• Press it again to deactivate the preset.
• Stations can be configured with an Off button. This option is performed at the station and should
only be done by a qualified technician.
• The group of presets controlled by any station can be altered at the station. This should only be
done by a qualified technician.

Redundant Tracking (ESR and FDX Racks Only)
Redundant tracking provides extra security in the event of system failure, allowing a secondary CEM3
control module to immediately take control of the rack. For more information, see
