Redundant Tracking Systems
CEM3 features the ability to support dual redundant controllers in ETC's ESR24, ESR36
and ESR48 rack types, as well as in the FDX3000 rack.
Redundant controllers provide extra security in the event of system failure, allowing a
secondary processor to immediately take control of the rack.
Redundant Tracking Switch
The redundant tracking switch determines which controller runs the output to the dimmers.
It has three positions.
•
When the switch is set to A (upper position), the upper controller has control of the
dimmers.
•
When the switch is set to B (lower position), the lower controller has control of the
dimmers.
•
When the switch is set to Auto (center position), control is automatically allocated
based on the health of the system (see below for details).
