12. DIM CURV
Configure the dimmer curve for each output.
There are four different dimmer curve profiles that can be assigned to each individual
dimmer output circuit. Square Law (SQ) curve is the industry standard and the default
for all dimmers. Linear (LN) curve modifies the dimmer output for a linear relationship
to the control input level. Direct Drive (DD) curve is not modified - meaning the control
input level is directly proportional to the control output level. Non-Dim (ND) curve
assigns the dimmer circuit to operate in a full-on or off state only, with no dimming.
Dimmers set for non-dim will be triggered full-on at 55% control input and will be
triggered off again at 45% control input.
Press EXECUTE to enter the menu.
DIM01 SQ
Displays the dimmer (DIM) output (01) and its current dimmer curve.
DIM06 SQ
Press MENU ( ) to select the desired dimmer number from 01 to 12 or 24.
DIM06 LN
Press EXECUTE to toggle to linear (LN) curve mode.
DIM06 DD
Press EXECUTE to toggle to direct drive (DD) mode.
DIM06 ND
Press EXECUTE to toggle to non-dim (ND) mode.
Press ESCAPE to exit the menu and save the desired dimmer curves.
Press RESET to exit the menu without saving.
The menu will automatically timeout after 2 minutes of inactivity and save.
13. VOUT LIM
Set the maximum RMS output voltage for each dimmer.
Limiting the maximum RMS voltage can greatly improve lamp life.
Press EXECUTE to enter the menu.
01<127.5
Displays the dimmer (01) and its current maximum output voltage level (127.5).
06<127.5
Press MENU ( ) to select the desired dimmer number from 01 to 06.
06>127.5
Press EXECUTE to toggle the pointer (< >) to select the output voltage level.
06>100.0
Press MENU ( ) to adjust the output voltage level in 0.5 Volt increments.
06<100.0
Press EXECUTE to toggle the pointer (< >) to select another dimmer number.
Press ESCAPE to exit the menu and save the desired dimmer curves.
Press RESET to exit the menu without saving.
The menu will automatically timeout after 2 minutes of inactivity and save.
NOTE: For 240VAC operation, the maximum output voltage level is 255 and the
output voltage limit is adjusted in 1 Volt increments.
14. REGULATE
Enable or disable the dimmer output voltage regulation.
With the on-board output voltage regulation feature enabled, the maximum RMS
output is limited to 118 Volts for 120VAC operation and 236 Volts for 240VAC
operation. Voltage regulation automatically adjusts the internal control level to
compensate for any line voltage fluctuations.
ENABLED
Press EXECUTE to toggle regulation from ENABLED to DISABLED.
DISABLED
Press EXECUTE to toggle regulation from DISABLED to ENABLED.
Any change in the configuration is automatically saved.
15. STANDBY
Enable or disable the power savings standby mode.
When standby mode is enabled the microcontroller goes to sleep within 5 seconds
of inactivity on the control inputs. The microcontroller wakes up again when a
programming switch is pressed or when control is sensed on the control inputs. Note
that there is a delay of 150 milliseconds for the microcontroller to wake up and restart
normal run mode.
ENABLED
Press EXECUTE to toggle standby mode from ENABLED to DISABLED.
DISABLED
Press EXECUTE to toggle standby mode from DISABLED to ENABLED.
Any change in the configuration is automatically saved.
