OPERATION
OVER TEMPERATURE CONDITION
The RA-122 has a temperature sensing element
which will shut down all operating channels if the
temperature rises above 175 deg F. A message
"OVERTEMP SHUTDOWN" will be shown on the
front panel display in this case. This shutdown cannot
be reset except by allowing the unit to cool down.
COOLING FAN
The RA-122 is cooled by a fan which is controlled by
the dimmers internal circuitry. It will begin running
when the unit is powered up. After a short
initialization period the fan will run if any dimmer
channels are at a non zero intensity and will time out
and turn off after aprox. 15 minutes of a "all channels
off" condition.
MANUAL OPERATION
Individual dimmer channels may be operated from the
RA-122 front panel. This is useful during testing and
setup operations. Use the and buttons to
select a channel. The associated channel on the bar
graph display will begin flashing. Use the and
buttons to raise/lower the lighting intensity for the
selected channel.
Manual operation combines with DMX and remote
stations settings but does not lock them out.
The CLEAR button will turn off all channels when
operating manually.
DMX CONSOLE OPERATION
If a DMX signal is present when the RA-122 is turned
on it will automatically respond to it. A "D" will be
shown in the lower right corner of the LCD display if
a valid DMX signal is present. Channel intensity
levels will be shown on the bar graph display.
