VIEW FULL OUTPUT V. View the Maximum output voltage of the dimmers, six at a time.
SET FULL OUTPUT VOLTS. Set the Maximum output voltage for any range of dimmers in the rack.
For instance, you can set the maximum voltage lower than the rated voltage of your lamps for improved
lamp life. If you have lamps or other equipment which operate at a lower line voltage, you can set the
output from the dimmer to an appropriate voltage for the devices.
The maximum output voltage is applied to all dimmers and dimmers assigned as non-dims. It is not applied
to contactor non-dims. You cannot use contactor non- dims for devices which need a maximum output
voltage setting.
NOTE: This function sets the dimmer output voltage, not the maximum control level applied to the dimmer.
CAUTION! Be careful when using a maximum output voltage with dimmers set for PANIC. When panic is acti-
vated, full output voltage appears at the output of any dimmer or non-dim set for PANIC, regardless of how the
maximum output voltage is set.
VIEW REGULATION MODE. View the dimming curve assigned to a range of dimmers, 6 dimmers at a
time.
SET REGULATION MODE. Set the Regulation Mode for a range of dimmers. These options are:
ThReg = Thyristor dimmer regulated
ThUnr = Thyristor dimmer unregulated
N-Dim = Non-Dim
SiReg = SineWave regulated
SiUnr = SineWave unregulated
IGBT = IGBT dimmers must be configured to this setting
SET CIRCUIT NAMES. View or edit the Circuit ID number for individual dimmers.
AUTONUMBER CIRCUIT ID. Automatically assign sequential circuit ID numbers to the dimmers.
DIMMER DYNAMICS MENU
The Dimmer Dynamics Menu allows you to view and configure dimmer information.
VIEW RESPONSE TIMES. View the response times for the dimmers, six dimmers at a time.
SET RESPONSE TIMES. The response time of a dimmer is the rate at which it responds to increases or
decreases in the control level. C21 / EC21 dimmer racks provide five response times:
Fast = 30ms Slow= 300ms Glacial = 1000ms Normal = 100ms Very Slow = 700ms
These options can be applied to a single dimmer or a range of dimmers. Slow is generally used for large
lamp loads, while fast is used for smaller lamp loads that might be used in a chase eect.
NOTE: The “fast” setting, together with the accuracy of digital dimmers can cause very high inrush current.
CAUTION! Do not use “fast” for IGBT dimmers or lamps that are 5kW or higher.
VIEW PROFILES. Allow you to view the dimming curve for the dimmers, six dimmers at a time.
SELECT PROFILES. Allows you to select the dimming curve for a range of dimmers:
SqLaw = Square Law
Old SqLaw = Legacy Square Law curve
S-Crv = S-Curve
Old S-Crv = Legacy S Curve
LinPw = Linear Power
N-Dim = Non-Dim
FlEle = Fluorescent Electronic
FlMag = Fluorescent Magnetic
MarkX = Advanced Mark X Ballasts
User1 = User Defined Dimming Curve #1
