Using Run mode
The VR can be programmed internally with an 8 position sequence which can
then be run without the need for a controller. This can be useful for
demonstration or display applications.
When the VR is in Run mode, it does not respond to or output DMX, except
when you are programming the positions.
Run mode menu
RUN

Press the middle button to enter Run mode.
The following sub-menu is then available. Press the MODE button to scroll
through the options, press any other button to select the option.
Play
PLA
_
Press the middle button to start playback mode. The VR will play back the
programmed positions at the speed you have set. If no positions have been set
the VR will ignore the command.
While the VR is in playback mode the display will show “RUN”. Press any key to
end the playback.
The other options on the VR (invert, snap, CE mode) will affect the playback
positions, so you should make sure the options are set correctly (the same as
they were set when you saved the positions) before starting playback.
If you turn the VR off while it is in Run mode, it will come back on in Run mode
next time you turn it on. The stored sequence is remembered until you use the
CLR option.

Press the middle button to enter record mode. You can then program the 8
positions:
If you have problems
The world of intelligent lighting can sometimes be confusing. You may at times
wonder if the lighting is more intelligent than you are. The next section lists a
few common problems you may encounter, with solutions.
No light from the VR
Check the ‘Power on’ (red) LED is lit and the fan is running. If not, there is no
mains supply. Check that the IEC socket is firmly pushed into the plug on the
back of the unit (this is also a common cause of intermittent operation). Check
your mains wiring and the fuse in the back panel.
Check if the lamp is alight. You should be able to see some light escaping
through the fan. If you have just turned the VR8 off and on again, the lamp will
not restrike until it has cooled down. On the VR4 the lamp will be off if all
control channels are zero.
If the lamp is alight, check that the VR is not in “blackout”. If you are using a
controller, change the setting. If in stand alone mode, tap the microphone.
VR not responding to DMX
Check if the DMX indicator dot (right hand dot) is lit. If not, check that your
DMX cables are connected properly and are wired correctly (the VR is wired
with pin 2 ‘hot’; some controllers may have pin 3 ‘hot’).
If the DMX indicator dot is lit, the VR is definitely receiving DMX but is
probably not responding to the channel you think it is. Check that the channel
set on the VR matches the controller’s settings. Also check that you have got
pins 2 and 3 of the DMX the right way round, as the VR can sometimes be
confused by upside-down DMX and turn on the DMX indicator dot.
If you have intermittent DMX problems, one ‘leg’ of the DMX may be
disconnected in your wiring. The DMX may continue to work intermittently
using the mains earth as a ‘common’.
Try using a different DMX source (controller or another scan) to check if that is
the problem.
