Channel settings

This section describes the individual settings for each channel in the Matrix rack.
Individual dimmers may be setup to have specific characteristics for a particular
application, such as maximum and minimum level settings, non-dim operation,
default fade in and fade out times etc.
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 warm up
lamp filaments, whereas the maximum level is used to limit power and extend lamp
life. Minimum levels between 0% to 29.9% may be set, and maximum levels may be
set from 100% down to 30%.
Factory default levels are 0% for minimum and 100% for maximum. One common
use for a reduced maximum level to control 110V lamps. However, for this situation,
the 110V dimmer curve is recommended as it produces a smoother control over the
whole range of intensity. If used, this result of using this feature should be checked in
comparison with other lamps in the rig to ensure uniformity of response.
To set-up max. and min levels:
1.
Select CONFIG. from the home menu, and press EDIT.
2.
The screen shows the individual channel number (or ALL if the dimmer set-up
scheme copies characteristics to all dimmers in the device) as follows:
CONFIGURE CHANNEL PARAMETERS
CH
ALL
Setting options are :
MIN: minimum level from 000 to 29.9%.
MAX: maximum level from 030 to 100%.
3.
Press EDIT and using the <<<< and >>>> buttons, choose MIN% or MAX%
[enabled when square brackets are shown] and set it to the required number
using the rotary encoder.
4.
Using the UP and DOWN buttons to address other channel numbers (unless all
dimmers are being set-up together).
5.
Press ENTER to leave the menu, then either SAVE (to record the changes) or
CANCEL (to leave the previous settings unchanged).

Response time

Each dimmer has two timings 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 and for reducing surges
in the system. The default times are currently zero seconds (for the fastest
response). Values recommended are 0.00s for a 2kW load, 0.05s for a 5kW load,
and 0.1s for a 10kW load
To set-up response times:
1.
Select CONFIG. from the home menu, and press EDIT.
