CONFIG: CH:[1]
MAX: 100%
2. Press Ï or Ð to select the required
dimmer number.
3. Press Î to select the maximum or
minimum option, and to highlight the
recorded value (in square brackets):
CONFIG: CH:1
MIN: [00.0%]
4. Setting options:
MIN : minimum level, 00% to 29.9%.
MAX : maximum level, 30% to 100%.
5. Press Ï or Ð to select the level (shown
in square brackets).
6. Press ENT to leave the menu and
record the changes or EXIT (to leave
the previous settings unchanged).
6.8 Response time
Each dimmer has two times associated with it
which control the minimum time to fade in and out,
and are called T-IN and T-OUT. These times are
referred to as ‘response times’ and are used to
protect the lamp filaments from thermal damage,
and for reducing surges in the system. The default
times are currently zero seconds (for the fastest
response). Values recommended are 0.01 s for a
1 kW load, 0.1 s for a 2 kW load, and 0.5 s for a 5
kW load.
6.8.1 To set-up response times
1. Press CONF.
2. The screen shows the individual
channel number (or T if the dimmer set-
up scheme copies characteristics to all
dimmers in the rack) and gives access
to all configuration options.
3. Press Ï and Ð to select the dimmer
number.
CONFIG: CH:[1]
MAX: 100%
4. Press Î to select the response times T-
IN or T-OUT, and to select the recorded
value (in square brackets):
CONFIG: CH:[1]
T_OUT: [00.00]SEC
5. Adjust the time by pressing Ï and Ð.
6. Press ENT to leave the menu and
record the changes or EXIT (to leave
the previous settings unchanged).
Note: Zero (0) seconds should not be used
with TV-type high wattage lamps, where
the minimum recommended is 0.05 s.
Faster response times should be used
with care, and with lower wattage loads.
6.9 Dimmer curves
Dimmer curves (dimmer laws) are used to adjust
the relationship between control level and light
output. This enables the dimmer to be fine-tuned
to accommodate the preferences of a live
audience or a television camera. There are 8
factory standard dimmer laws, and a provision for
further custom selectable curves in later software
releases.
The factory default law (0) is Linear Law. The
following dimmer curves are available:
LINEAR linear relationship (standard)
LINEAR5 LIN5 (as linear but with a small
offset at 50%)
INV.LIN inverted (when control = zero,
dimmer = full etc.)
110V LIN 110V lamp load, linear law
S-LAW S-Law
BBC
BBC specification (modified
square law for TV applications)
FLU-50 fluorescent (minimum 50%)
FLU-30 fluorescent (minimum 30%)
FLASH flash effect (light switches on
and off as the control fades up
and down)
NONDIM non-dim operation (see note
below)
9-14 for future use
Note: There are two options for setting Non-
Dim (switch) operation – via the CURVE
menu and the NON-DIM menu, both
found in CONF. For Non-Dim operation,
either or both options may be set, but for
normal dimmer operation BOTH must be
set to ‘NO’.
6.9.1 To select a dimmer curve
1. Press CONF.
2. The screen shows the individual
channel number (or T if the dimmer set-
up scheme copies characteristics to all
dimmers in the rack) and gives access
to all configuration options.
3. Press Ï or Ð to select the channel
number.
CONFIG: CH:[1]
CURVE: LINEAR
4. Press Î to select the CURVE option
(shown in square brackets) and set the
curve option by pressing Ï and Р.
