System configuration Unison rack dimming software version 2.0

 

To access configuration menus

  1. Press the concealed menu activate button for three seconds. Menu screen will appear. See Figure 1 for concealed button.
  2. Press [up arrow] or [down arrow] to scroll through bracketed options.
  3. Press [Enter] to move bracket placement to the right.
  4. Press [Exit] to move bracket placement left.

To reset a Control Module

When the rack door is open, a Reset button is available in the top right corner. Pressing it restarts the Control Module using saved settings. Resetting will temporarily interrupt all Control Module processing. Lights will flash momentarily or may go out while system boots.

 

 

 

To initialize a dimming rack

Initialization refers to the programming of rack voltage, size and DMX start address. The first time you access menus on a Unison dimming rack, you must initialize the dimming system processor.

  1. Complete Rack Configuration Chart.
  2. Press the concealed "Initialization activate" button for three seconds. The [Stat] menu will be displayed.
  3. Use [] or [] to scroll to the [Rack] menu.
  4. Press [Enter] to move the brackets underneath Control and use [] or [] to select the the appropriate dimming rack or external processing rack control module.
  5. If you have selected a dimming rack, move the brackets underneath Rack and use [] or [] to select either DR6 or DR12.
  6. Press [Enter] to move the brackets underneath Volt and use [] or [] to select the voltage that matches your feed, either 100-120, 120 Delta or 277 VAC.
  7. Press [Enter] to move the brackets underneath Start and use [], or [] to enter a DMX512 starting address for your rack between 001 and 512.

    DMX start address - the DMX512 channel number (between 1 and 512) applied to the first dimmer in the rack. Succeeding DMX channel numbers are automatically applied to the remaining dimmers.
     
  8. Press [Enter] to move the brackets underneath Sequencing. Select either Straight or Balanced.

    Straight or Balanced refers to how the DMX addresses will be distributed to the dimmers. Straight indicates that the distribution will be sequential starting at one. Balanced indicates that sequential loads will be distributed evenly over the three phases in the rack.
 Note: Single-phase racks cannot be phase balanced, as the racks are not split evenly.
  1. Press [Enter] then [Exit]. The display changes to Update Rack? Use [] or [] to select Yes. Press [Enter] again to save changes and leave the Rack menu.

To detail dimming circuits

The Unison dimming processor is designed to control (dim) multiple lighting circuits. Control of each circuit is based on installed module type, connected load type, DMX address and circuit mode.

  1. Access configuration menu (press the Unison Menu activation button.)
  2. Scroll to [Cnfg] with [] or [] and press [Enter]. The brackets move to the circuit number.
Note: Circuit numbers start with “1” for the first dimmer in the top slot of the rack. A rack can have one or two dimmer circuits per module. Dimmer load wire lugs are also labeled by circuit number.
  1. Select the desired circuit number with [] or [] and press [Enter]. The display changes to Module Type.
  2. Select the correct module type with [] or [] and press [Enter]. The display changes to Load Type.

  1. Select the desired DMX512 address with [] or [] and press [Enter]. The brackets move to Mode
Note: It is important to note the circuit to DMX channel assignments. Select the DD mode with [] or[] and press [Enter]
Caution: Dimmer doubling is only available in 120V systems using Source Four fixtures with 77V lamps.
  1. If a 2-, 3-, 4-wire fluorescent or Neon/CC is selected in load type the display will move to Ballast Type. Use [] or [] to scroll to the correct type.
  2.  Use [] or [] to scroll to [Yes] to record your changes or scroll to [No] to discard changes and press [Enter]. The display returns to the circuit number step of the [Cnfg] menu. Use [] or [] to begin configuring another dimmer circuit. Or press [Exit] to leave the Configuration submenu.

To enter Dimmer Doubling (DD) settings

Dimmer Doubling (DD) can only be used in 120V systems using D15, D20, D15E, and D20E modules. This feature is used for applications where ETC Dimmer Doubling and Source 4 equipment is used. If you have not purchased Dimmer Doublers, this feature must be turned off.

  1. Select either [DD_On] or [DD_Off] with [▲] or [▼] to enable or disable Dimmer Doubling and press [Enter]. If you select [DD_On] the display changes to [DD_DMX]. If you select [DD_Off], Save Changes? displays.

To set dimmer levels in the Test submenu

You can use the Test submenu to set dimmer levels to test your dimmer circuit wiring or lighting load operation. Test also allows you to view DMX levels being received by the dimming processor.

  1. Access the configuration menu (press the Unison Menu activation button.)
  2. Scroll to [Test] with [] or [] and press [Enter]. The brackets move to Ckt. The DMX input value for that circuit is displayed between a range of 0 and 255.
  3. Use [] or [] to scroll to the desired circuit number and press [Enter]. The brackets move to Level. This shuts off all DMX to the rack. DMX levels are held at last look and DMX level changes have no effect.
  4. Use [] or [] to scroll to the circuit output level. Circuit output will continuously match the levels as they scroll. Press [Exit] to set levels on another circuit or [Enter] to go to Restore DMX?. (Restoring DMX will cancel all test levels.)
Note: Circuit levels will remain at their test setting when you press [Exit]. You can set levels for all the dimmer circuits by repeating steps 2 and 3.
  1. Use [] or [] to scroll to [Yes] to clear the test settings and restore DMX or [No] to temporarily keep the look and press [Enter].
Note: If you keep the test settings, DMX512 input is disabled until you return to the Test menu and restore DMX.

 

 


To set dimmer levels in the Set All submenu

The [Set All] submenu is an additional test menu. It allows you to change all of the levels in the dimmer rack.

  1. Access the configuration menu (press the Unison Menu activation button.
  2. Scroll to [Set All] with [] or [] and press [Enter].
  3. Use [] or [] to change the level of all dimmers.
  4. Press [Enter], and use [] or [] to scroll to [Yes] to clear the [Set All] and restore DMX. Or [No] to temporarily keep the look and press [Enter].


 

 

 

 

 

To set the Backup look

In the event of console failure, the backup look enables you to activate a single preset at the CMd or CMEd.
