JB-Lighting Varyscan P8 - Handbuch (Seite 45)

- 45 -
The P8 features a color wheel channel, main RGB and CTC channel. The colour wheel channel
has priority. Only if the color wheel channel is set to DMX value 000-001 it is possible to operate
the RGB channels. The CTC channel can be combined with both, the RGB channels and the
colour wheel channel.
The control channel (channel 5) offers additional control over the RGB-channels.
DMX 000-007: no white balance active.
DMX 008-015: basic adjustment on the RGB channels. So it‘s possible to have always the same
white from different production series (factory adjustment). Marginal reduced intensity of the
RGB strings.
DMX 016-023: White balance, reduced intensity in blue, possible reduction in intensity of green
and red. If fixtures are set to this DMX value the white of fixed colors (color 0) and RGB color
mixing is the same.
DMX 024-031: White balance same to DMX 016-023, plus the RGB curves are working in linear
mode so it is possible to use the color picker function of various lighting control desks.
Some lighting desks have a delay during DMX refreshing and DMX values get missed during a
fade out or using the fader. That means the P8 with his fast reaction time rate this happen as a
shutter and shows flickering in the beam. To avoid this you can select 5 different modes. Depen-
ding on the modus, the reaction time of the P8 gets lower.

RESET FIXTURE
This menu offers the command to reset the P8 and can be used as a first remedy if an error
occurs.
ERROR LIST
The ERROR LIST command displays a list of any errors detected. An error can simply be a
harmless and isolated incident, but if repeated errors occur, the P8 may require service or repair.
FUNCTION TEST
This menu provides a general test of all effects. It allows testing without controller. The
re-positioning of pan/tilt is disabled.
DMX TEST
This menu view the DMX values received on each channel. If the P8 does not behave as expec-
ted, reading the DMX values can help to troubleshoot.
INIT PAN TILT
The INIT PAN TILT feature reinitializes pan and tilt relative to their end stops. Use it if pan and tilt
appear to have lost calibration. That means if the pan or tilt beat the reset point or loose the find
back position. This process will take approx. 10 minutes and finishs with a reset.
DISPLAY CONTRAST
During a heating treatment the contrast of the LCD display can vary. The setting of the contrast
can change in this menu.
