Forward-Phase Dimmer–Gen 2
Fluorescent Voltage Adjustment Mode
This mode adjusts the minimum turn-on voltage used by Fluorescent dimming
mode. Press and hold the Dim Mode button for 5 seconds to enter
Fluorescent Voltage Adjustment mode. The LED is amber when this mode is
active.
Note:
120 VAC models are set to turn on at 56 VAC, and 277 VAC models are
set to turn on at 129 VAC.
Press the Dim Mode button again to increase the "turn on" voltage by 2%,
or press the Dim Phase button to decrease the "turn on" voltage by 2%.
Because the Forward-Phase Dimmer–Gen 2 outputs at the current turn-on
level while in Fluorescent Voltage Adjustment mode, you can make
adjustments with the loads on, regardless of the input control state.
Press and hold the Dim Mode button for 5 seconds to save the setting and
exit Fluorescent Voltage Adjustment mode.
