loads. When disabling Voltage Regulation, you should also set the Maximum Scale Voltage
to a level well above the incoming line voltage to ensure that power wave is not clipped in
any way.
Preheat [Power]
This setting enables/disables preheat for the selected dimmer. The preheat level is the
Minimum Scale Voltage.
Dynamic Preheat [Power]
This setting allows quick blackouts on dimmers that are set to preheat. It sets the amount
of time a dimmer will remain at a zero (0) level before returning to the preheat level. It can
be set from 0.5 seconds to 15 seconds and has a default of 2 seconds.
DC Output Prevent [Power]
This setting offers protection on selected dimmers for loads that are sensitive to DC buildup,
which can occur under certain conditions when positive and negative half-cycles become
uneven.
Inrush Protection [Power]
This setting protects against large voltage increases in a single AC cycle. This protection is
useful for high-wattage loads that may cause nuisance tripping of circuit breakers and to
limit peak currents in wiring and switch gear. This protection is particularly useful on RCD/
GFCI protected circuits. Settings for inrush protection include: Instant, 100mS (for loads up
to 10A), 300mS (for loads up to 25A) and 500mS (for loads of 50 or 100A).
Advanced Features (AF) [Power]
Enables/disables additional feedback from a dimmer that provides load recording/reporting
and advanced error reporting including a breaker trip, module removed, load changes, dc
output and SCR failures.
(Report) Load Errors [Power]
Enables/disables messages to report load changes once initial loads have been recorded
for a dimmer. Load errors must be enabled to record loads in Load Management. See
“Load Management” on page 29..
AF Sensitivity (1-10) [Power]
This setting defines the resolution of the advanced features sensitivity to report load
changes. One (1) is the most sensitive/highest resolution setting and the default is 5. AF
sensitivity is based on a percentage of the recorded load.
AF Reaction (Time) [Power]
This setting defines the hysteresis for an advanced feature error. The error must be present
for the minimum set in the AF Reaction Time before an error will be reported. Five (5)
seconds is the shortest amount of time and 60 seconds is the longest allowed.
Scale Load [Power]
This setting adjusts the choke correction curve based on the specified percent load of the
maximum for that dimmer type. Scale Load can be set from 1% to 100% and should reflect
the approximate percent load on a given dimmer to precisely match all dimmed load. The
default setting is 35% which is based on a single Source Four 750w fixture on a D20
dimmer with a max scale voltage of 115Vac.
