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:
The allowed range is 0–100% of the input voltage. By default,
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.
Troubleshooting
Error Indicators
The Dim Phase LED and Dim Mode LED (see image on
) double-blink
red in unison when the dimmer is too hot. Ensure that the dimmer is in a
suitably air-conditioned space and that free air is able to move around the
heat sink.
Restore Defaults
To return the Forward-Phase Dimmer–Gen 2 to factory defaults, set both
rotary switches to 16 and then press and hold both the Dim Mode and the
Dim Phase buttons for 10 seconds. The LEDs will blink red quickly to indicate
that the factory defaults have been restored.
Note:
After you return the Forward-Phase Dimmer–Gen 2 to factory
defaults, reset the rotary switches to the appropriate values for the
controller zone and space.
