LED Function Explanation
The Yellow LED indicates Local Control when lit and DMX control when not lit.
The Red LED (nearest the Green LED) indicates low voltage -- less than 22VDC. The
dowser will operate with this LED lit but if it is lit continuously, it alerts you to the fact
that the voltage is low and the Coloram II cable to the Coloram II Power Supply may be
too long.
The Green LED indicates that the dowser has 24VDC power.
If all the LEDs are flashing, the voltage has dropped below 15VDC for more than one
second and the dowser has shut itself down. It cannot operate properly below 15VDC.
The voltage typically drops this low if the Coloram II cable is too long -- the 1000
head-feet limit has been exceeded. You must shorten the Coloram II cable to solve
this problem.
DIP Switch Function Explanation
DIP switch #1 selects DMX control or Local Control. See the OPERATING MODES
information below.
DIP switch #2 selects SNAP MODE ON or OFF. If the Snap Mode is OFF, and control is
set to LOCAL, the Local Control buttons will open and close the fins over a period of
five seconds. If the Snap Mode is ON, and control is set to LOCAL, the Local Control
buttons will open and close the fins very quickly. Snap Mode has no effect when in the
DMX control mode.
DIP switch #3 sets the channel range to 1 thru 12 or 13 thru 24. See the CHANNEL
SETTING information above.
DIP switch #4 selects Fast Mode or Smooth Mode. Selecting Fast Mode will allow the
iris to open and close in a minimal amount of time. Selecting Smooth Mode will
increase the amount of time required to open and close the iris, but will result in
quieter and smoother operation. This mode works in both Local Control and DMX
Control.
Operating Modes
The Eclipse II Dowser has three modes of operation. In all cases, the Coloram II
Power Supply is needed for control and power. DIP switch #1 on the dowser selects
the control mode -- DMX or local.
1. DMX512 control -- the level (0-100%) of the DMX channel to which the dowser
is addressed determines the fin position. The fins will be closed at 0% and will
be open at 100%.
