The channel levels will remain when you set them.
The control console can turn off the test setting by
raising the applicable channel fader to full then back
down. The channel test feature operates much like the
LOCAL mode. The difference is that local mode
LOCKS OUT all other control sources.

A usefull feature of the channel test mode is that the
display shows the current intensity level of the
channel regardless of the control signal source.

DIMMER SETUP

The dimmer setup menu (

dSEt

) enables you to set

several parameters which control how each individual
channel will operate. You can set a DMX address, set
a maximum intensity limit, and set a response curve.

Hold

MENU/NEXT for aprox. 5 sec. to access the

dimmer setup menu. The display will show

dSET

CHANNEL ADDRESSING (SOFTPATCHING)

In order to invoke the softpatching settings you must
first set the pack address (

PACA

) to

P000

. You

can set the channel DMX softpatch addresses at any
time but they will be ignored if

PACA

is not at

P000

TO SET CHANNEL SOFTPATCH ADDRESSES

Push

SELECT at the

dSEt

menu. The display will

toggle between the

dA-A

and the current DMX

address assignment number.

Use to set the desired DMX address (000 - 512)
for that channel. Push

SELECT to save the change.

Push

MENU/NEXT move to the next channel.

CHANNEL LIMITING

Each channel in the XC-40 can be set to limit the
maximum power applied to a channel. This feature
can lengthen the life of lamps and prevent premature
failures from power surges and high line voltage. The
following table gives the approximate XC-40 menu
setting for some typical limit percentage settings.

% MAX.

Intensity

Dimmer Limit

Setting

100 255

90 230
75 190
50 130
25 65
10 25

Note that limiting reduces the voltage applied to the
channel. The perceived light from the fixture will not
necessarily appear to track the limit setting in a linear
fashion.

Push

SELECT at the

dSEt

menu. Then push

MENU/NEXT until the display toggles between

dL-A

and the actual limit value

010 - 255

Use and to set the desired limiting value for that
channel. Push

SELECT to save the change.

Push

MENU/NEXT to advance to the next channel.

RESPONSE CURVE SELECTION

The XC-40 provides a selection of five response
curves to select from to accommodate a variety of
lamp and fixture types:

DIM:

Used for normal incandescent lamps.

RELAY:

Used for devices which cannot be dimmed or

for ON/OFF only control.

LED1 / LED2:

Two curve settings for LED fixtures.

FLUORESCENT:

For dimmable fluorescent ballasts

which can be used with a conventional dimmer.
These are sometimes referred to generically as "two
wire" ballasts.

Push

SELECT at the

dSEt

menu. Then push

MENU/NEXT until the display toggles between

dC-A

and the current curve setting.

Use to set the desired curve for that channel.
Push

SELECT to save the change.
