Each channel can be individually configured to operate in one of the following modes,
3.6.1
ALWAYS OFF
The channel cannot be turned on
, except in “Emergency Mode”. See section 4. Warning, do
not rely on this setting to isolate the power.
3.6.2
AUTO POWER
Auto Power is a feature that sequentially switches ON channels set to Auto Power mode. This
helps to prevent nuisance tripping of circuit breakers due to high in-rush currents on power-
up.
The start of the switch-on sequence (also known as a staggered start) can be either manually
triggered from the touch screen by selecting the
CONTROL
button or automatically triggered
whenever the channels selected control signal is present. AutoPower channels with a control
source do not listen to any specific DMX slot. Instead, they look for the presence of the source
DMX universe (DMX, Art-Net or sACN) according to the control source selected for that
channel. The switch on sequence is started when they see a valid DMX signal from their
selected source. When the selected control source is no longer detected, the Auto Power
channels are switched OFF.
A “Hold Time” can be set to prevent channels being turned off if there is a short interruption to
the control signal and the stagger start time can also be set. See section 3.12
Channels whose “Control Source” is set to “None” can only be manually triggered to start the
switch on sequence or switched off by selecting the
CONTROL
button.
3.6.3
ALWAYS ON
The channel cannot be turned off (except by turning off its channel circuit breaker). When
power is applied they will be sequentially switched on in the same manner channels set to
“Auto Power” mode above.
3.6.4
SWITCH 60%-40%
The channel will act as a power switch and is individually switched by the DMX level of a slot
to which it is patched. When the level of the DMX signal is 60% or higher the switch turns on.
When the level of the DMX signal drops below 40% the switch turns off. This is the best mode
to provide remotely controlled power to lighting fixtures and AV equipment.
3.6.5
RELAY 1%-0%
The channel will act as a power switch and is individually switched by the DMX level of a slot
to which it is patched. When the level of the DMX signal is 1% or higher the switch turns on.
When the level of the DMX signal drops to 0% the switch turns off. Relay mode is particularly
useful when the controlling device is programmed with long fade times. T
he “Relay” channel
will switch on at the start of the up fade and switch off at the end of the down fade.
3.6.6
DIMMER
The channel will act as a dimmer and it level is individually controlled by the DMX level of a
slot to which it is patched. In dimming mode, the channel utilizes pulse transformer circuitry
which allows it to control difficult loads including neon, motors and low wattage lamps as well
dimmable LEDs and convention incandescent lamps. This mode is not available on USMT
switch modules.
3.7
SOURCE/PATCH
From the “Home Menu” tap
SOURCE/PATCH
. The screen shows the current source and
address of each channel.
Selecting a control source and patching is a three-step process,
