After Startup
1. Check the following items to make sure they are correctly set in the processor module:
• Rack type
• Phasing
• Starting multiplex signal number and dimmer protocol
• Input Voltage
• Dimmer numbering
Other items you may wish to check at this time, depending on your system configuration, are:
• Mux patch
• Outlook patch
• Max Voltage
• Min Level
2. Switch on all load circuit breakers.
3. Connect a suitable luminaire to each outlet and check every dimmer using the SET LEVEL control facility or a
suitable control console. Investigate and correct any malfunctions you find.
NOTE: If any dimmers do not work, stop and check the slot type for the dimmer. Dimmers will not work prop-
erly if their slot type is incorrectly assigned. Make sure that all of the modules are in their correct slots, and that
the slot type for each dimmer is correctly set in the processor module.
4. Install the fan grill and door to complete the system installation.
OPERATIONAL FEATURES
RACK CONFIGURATION
The following configuration items are usually programmed during commissioning, but can also be repro-
grammed by the user.
• Rack name.
• Panic selection and configuration.
• Maximum output voltage (per dimmer): 20-250 volts (e.g. set to 105V for extended lamp life).
• Minimum level (per dimmer): 0% - 100% (e.g. set to 10% for aisle lights or large lamp preheat).
• Room and channel Patching.
• Each dimmer can be patched to any valid DMX512 address number for the standard input A (DMX512 A),
input B (DMX512 B) or network.
• Circuit ID—used by status reporting software.
• Define Preset Number or “Hold” condition on DMX512 failure.
• Define power-up preset.
• Set LCD contrast.
• Error log accessible from the processor module or status reporting software.
• Individual dimmer reporting enable/disable.
DIMMER CONFIGURATION
Configuration items associated with the dimmer module can be set from the processor module front panel.
• The output response profile can be set to Linear, Square, S-Curve, Fluo- Electric (for electronic fluorescent
ballasts), Fluo-Magnetic (for magnetic fluorescent ballasts), and Non-Dim. The two fluorescent settings
let you set the top end voltage and the bottom end cuto voltage. The Non-Dim setting lets you set the
turn-on threshold for the non-dim. Five additional user programmable profiles are available through the Set
Rack Configuration menu or from the optional status reporting software.
• Dimmer response (per dimmer): fast (30ms), normal (100ms), slow (300ms), very slow (700ms) or Glacial
(1000ms). This determines a dimmer‘s rate of response to a change in control level. Slow is usually set for
large tungsten loads to reduce filament inrush, medium or fast for small loads.
