• Dynamic Preheat: this setting allows quick blackouts on dimmers that are set to

preheat. Preheat settings are not available to the User level login.

• DC Output Prevent: 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: this setting protects against large voltage increases in a single AC

cycle. This protection is useful for high-wattage loads (especially if comprised of many

smaller wattage lamps) that may cause nuisance tripping of circuit breakers and to limit

peak currents in wiring and switchgear. 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).

Set Threshold [

Power

]

The Set Threshold menu allows a Power User to set a dimmer or a range of dimmers to

come on at a specific control level.

Set Max Scale Voltage [

Power

]

The Max Scale Voltage menu allows a Power User to set a dimmer or a range of dimmers

to a maximum output voltage that is the top (100% control) of the scaled output of that

dimmer.

Set Min Scale Voltage [

Power

]

The Min Scale Voltage menu allows a Power User to set a dimmer or a range of dimmers

to a minimum output voltage that is the bottom (1% control) of the scaled output of that

dimmer. The dimmer will switch on to an RMS output voltage of Min Scale Voltage when

the control level reaches the value set for threshold. This is also the dynamic preheat value

for the dimmer.

Assign Dim to Room [

Power

]

The Assign Dimmer to a Room menu allows a Power User to set a dimmer or a range of

dimmers to a specific room for use with recording presets. A dimmer can only be assigned

to a single room at a time. There are four (4) rooms available and all dimmers default to

being assigned to Room 1.

Advanced Features [

Power

]

The Advanced Features menu allows a Power User to set Advanced Features (on/off),

Report Load Errors, AF Sensitivity, and AF Reaction Time for a dimmer or range of

dimmers.

• Advanced Features (on/off): 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 (on/off): allows for messages to report load changes once initial

loads have been recorded for a dimmer.

• AF Sensitivity (1 to 10): defines the resolution of the advanced features sensitivity in

reporting 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 (5 to 60 seconds): 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.

Dimmer Check [

User

]

The Dimmer Check menu allows a User to set an output level and then step through

dimmers at a selected starting point.
