6.7 Maximum & Minimum levels
It is possible to affect the output range of a dimmer
by setting a minimum level and (or) a maximum
level. A minimum level is used to provide a pre-heat
to preheat lamp filaments, whereas the maximum
level is used to limit power and extend lamp life.
Minimum levels may be set between 0% to 29.9%,
and maximum levels from 30% to 100%. Factory
default levels are 0% for minimum and 100% for
maximum. One common use for a reduced
maximum level is to control 110V lamps but the
110V dimmer curve is recommended as it produces
a smoother control over the whole range of intensity.
However this should be checked in comparison with
other lamps in the rig to ensure uniformity of
response.
Note: In the case of high-inrush loads (e.g.
Parcans) where flashing on from a cold
state is required, a preheat level of 5% is
recommended. See also section 6.5.5 on
DMX Minimum Reset.
6.7.1 To set-up max. and min levels:
1. Press CONF.
The screen shows the individual channel
number (or T if the dimmer set-up scheme

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 0.01s for a 1kW load or 0.1s for a
2kW load.
6.8.1 To set-up response times:
1. Press CONF.
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.
2. Press

number.
CONFIG: CH:[1]
