16. 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.
DIM24 SQ Press MENU ( ) to select the desired dimmer number from 01 to 24.
DIM24 LN Press EXECUTE to toggle to linear (LN) curve mode.
DIM24 DD Press EXECUTE to toggle to direct drive (DD) mode.
DIM24 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.
17. 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).
24<127.5 Press MENU ( ) to select the desired dimmer number from 01 to 24.
24>127.5 Press EXECUTE to toggle the pointer (< >) to select the output voltage level.
24>100.0 Press MENU ( ) to adjust the output voltage level in 0.5 Volt increments.
24<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.
18. 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. 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.
19. ANA MODE Configure the analog inputs for normal or load shed mode.
Each of the four (4) analog inputs can be independently configured for normal
(NORM) or load shed (SHED) mode of operation.
Normal (NORM) mode sets the analog input for 0-10VDC operation. The analog
voltage level sensed sets the level for the selected dimmer outputs.
Load shed (SHED) mode is used as a power management interface to building
management systems (BMS). Contact closure devices such as a photocell or
maintained switch contact may be used to trigger the analog input. When a voltage
of 5.5VDC to 12VDC is sensed on the analog input the selected dimmer outputs are
disabled (set to zero output level). The selected dimmer outputs are enabled when
the voltage sensed on the analog input drops to below 4.5VDC.
Press EXECUTE to enter the menu and set the mode for each analog input.
A01 Displays the active analog input (A01) and current mode setting (NORM).
A04 Press MENU ( ) to select the desired analog input to configure.
A04 Press EXECUTE to toggle from normal (NORM) to load shed (SHED) mode.
Press ESCAPE to exit the menu and save the desired analog input modes.
Press RESET to exit the menu without saving.
The menu will automatically timeout after 2 minutes of inactivity and save.
