Manual Operation
Lamp Select Feature
The
4Bank
and
4Bank DMX Ballasts
have a
4ft/2ft
switch. Set the selector switch to
4ft
for 4ft lamps.
When operating 4ft lamps in high ambient temperature or where the units are rigged
into place with restricted airflow, the
2ft
setting can be used to lower the color
temperature and remove any green spike. The light drops about a ½ f-stop in
exposure when dropping from
4ft
to
2ft
setting.
Note:
The manual
2ft/4ft
switch is disabled as soon as the DMX cable is applied.
To manually control the
2ft/4ft
switch with DMX cables plugged in:
1) Unplug the DMX cable or
2) Leave cables plugged in and set DMX address to “000”.
There is a 5 second delay when switching between DMX and Manual Control.
