Navigation Buttons
The navigation buttons ([Test], [About], [Setup]) and the [Back] button are used to navigate menus in
the display window (see
). Press [Back] to return to the previous screen on
any menu.
Performing a Quick Setup
Quick Setup is used to set up your rack using a minimum amount of data to achieve a basic
configuration.
You can begin a Quick Setup by selecting Quick Setup from the main screen or by navigating to
[Setup]>Quick Setup>[Enter].
From this screen you can use the CEM3 interface to enter data in up to four screens to quickly establish
your rack configuration: Module, Circuit, Dimmer Double, and Patching (see below for screen
descriptions).
Once you have entered data in the screens, select OK and press [Enter] to save the setup changes.
Module
The current Rack Type is listed. To change the module type select Module. Select a module type and
model from the list, then select Next. The rack will be configured as filled with the selected module
type. If you don’t need to change the module types, leave the type as Unchanged.
Circuit
Set Numbering to either Renumbering or Unchanged to indicate whether to renumber the rack. If you
select Renumbering, set these two additional parameters:
• Set the Starting At value to the number for the first circuit in the rack. If this is your first or only
rack, this number is typically 1. If this rack is one of many in your system, this number typically
continues the numbering sequence from the previous rack. Default is 1.
• Set the Balance type: Straight, 1-Phase, or 3-Phase. The CEM3 processor defaults to the balance
type that is appropriate for the detected power source, but you can change this value if desired.
- Straight results in circuit numbering that will proceed sequentially straight through the entire
rack.
- 1-Phase or 3-Phase results in circuit numbering that distributes the circuits evenly across the
different power phases so that neighboring circuits do not place an uneven load on any phase.
Note:
Prior to performing a Quick Setup, make sure that your rack DIP switch settings are
set appropriately for your rack type. See
Setting Rack DIP Switches and Termination
.
CAUTION:
Quick Setup will overwrite some of the data in your rack. Only perform a
Quick Setup when you want to reconfigure your system or are instructed to
do so by ETC Technical Services.
