This screen is showing you the current global settings of the control module:
Display Rack #01
Default rack number. If no one has set up the HHT configuration before, then this is probably what you'll
see. If someone has already configured the rack it will probably display 01, 02 or something with a logical
number association.
Upper Control Module
Indicates that you are viewing configuration of either the “upper” or “lower” control module. If the
displayed value is incorrect, it should be changed in configuration mode.
120 Volt System
Indicates the current system voltage, either 120V or 240V.
Pressing the (MORE) soft key gives you the next screen which shows the following rack settings:
DMX Hold Time = 0 min
This is the amount of time the control module will hold the last DMX packet it received before fading to
black. A [0] hold time will cause the control module to hold the last packet for about five seconds and then
fade to black. A[5] minute hold time will cause the control module to save the last dmx packet for 5 minutes
and then fade to black. A[ 9] minute hold time will cause the control module to save the last dmx packet for 9
minutes and then fade to black. An [i] minute(infinite) fade time is set by the [FL] key when in configuration
mode, and will cause the control module to hold the last dmx packet forever. Valid values are 0-9 minutes, or
i for infinite.
Line Regulation=SLOW
The choices are [FAST] , [SLOW] and [OFF]. Line regulation is a feature that attempts to compensate for
incoming power feeder fluctuations. The control module monitors the voltage of the incoming line and
compensates for line surges and sags over the course of several dozen cycles. Examples of the normal
application for line regulation:
Brown Out. Lets say during the course of your show, the incoming power line drifts down
from 120VAC to 113VAC. Lights that are under dimmer control under 109 Volts will
automatically "dim up"to compensate for the power line sagging down. This will cause
your lights at half intensity, or about 84VAC RMS, to remain at 84VAC. If the line goes
back up, even higher perhaps, the output at half intensity should remain at about
84VAC. The lights that are on at full however, will dim down as the power line sags
because the are already dimmed up as far as they can be.
Boosted Power Feed. Some installations feed the dimmer racks with a "Hot" power feed of
about 125 to 130VAC RMS. This is done so that if the power feed is hot enough to
