dimmers to zero (or to the levels generated by the next highest priority source) in a
user-defined fade time. The maximum wait and fade time is 60:59 minutes.
• Play Preset: this setting will play back a preset when data is lost. The default fade time
is 2 seconds. The preset that is activated is set in the Groups>Presets menu. See

Set First Dimmer
Set First Dimmer allows you to set the first dimmer number in a selected rack. For example, with two
SR48 racks, Rack 1 defaults to a First Dimmer of 1, and Rack 2 defaults to a First Dimmer of 97.
There is also an option to establish "hotel" addressing at time of rack creation. This is done by setting
the first rack's first dimmer to 101. The CEM+ will then ask you if you want all of the racks in the group
to use this method. In this scheme, the first rack begins with dimmer number 101, the second rack's
dimmers begins with dimmer number 201 and so on regardless of the number of actual dimmers in the
racks. So the number of unused dimmer numbers between racks will vary. For example, SR6's would
typically leave 88 dimmer numbers unused between racks while and SR48 would only leave 4.
Advanced Features [Power]
The Advanced Features menu allows you to enable/disable Advanced Features (AF) for a selected rack
in the group.
No Load Alarm/Errors [Power]
Enabling "No Load Alarm" allows a technician to immediately receive a notification of any dimmer that
does not have any lamps drawing current (0 amps) when the dimmer is above 25 percent (assuming
mod square curve).
Set Group / Rack [Power]
The Set Group / Rack menu allows you to set the rack number of your local rack and the group number
it belongs to. This should be done before creating a configuration. Care and understanding should be
used when making a change to these settings after a configuration is already loaded.
Set Rack Name [Power]
The Set Rack Name menu allows you to set the name of the rack you are currently browsing. Names
are alphanumeric and can be up to 20 characters long (18 characters will be visible on the LCD).
Set Phase Balance [Power]
The Set Phase Balance menu allows you to set the type of phasing used by the selected rack and the
voltage of the line feed power. Available settings include: Balanced-3Phase, Balanced-1Phase, Straight-
3Phase and Straight-1Phase.
• Balanced-3Phase: rack is fed 3-Phase power and dimmer numbers are distributed numerically by
phase, rather than by rack position. Example: dimmers 1 and 2 are in the top slot of a rack;
dimmers 3 and 4 are located first on the second phase, 1/3 of the way down the rack; dimmers
5 and 6 are located first on the third phase, 2/3 of the way down the rack.
• Balanced-1Phase: rack is fed split-phase power and dimmer numbers are distributed numerically
by bus bar, rather than by rack position. Example: dimmers 1 and 2 are in the top slot of a rack;
dimmers 3 and 4 are located in the first dimmer module of the bus bar, 1/2 of the way down the
rack.
• Straight3-Phase: rack is fed 3-Phase power and dimmer numbers are distributed numerically from
top to bottom in the rack. Example: dimmers 1 and 2 are in the top slot of a rack, dimmers 3 and
4 are located in the next slot, etc.
• Straight1-Phase: rack is fed 1-Phase power and dimmer numbers are distributed numerically from
top to bottom in the rack. Example: dimmers 1 and 2 are in the top slot of a rack, dimmers 3 and
4 are located in the next slot, etc.
