4.2. Analog control input
The VX control electronics also accepts analog control signals. The DC level needed for full
output is factory set at 10 volts, but can be readjusted in the range of 5 to 24 volts DC.
The analog control connectors are 8 pin male Jones type. The pin connections are shown below:

5. Dimmer Circuit Controls and Indicators
Each dimmer chassis contains twelve independent dimmer circuits, each with the following
controls:
5.1. Circuit Breaker
The channel breaker is the first line of defense against shorted lamps or load circuits. A special
type of magnetic breaker has been chosen for the VX system. This breaker allows only a fraction
of the energy to pass through the system in the case of a short in the load or load wiring as
compared to conventional magnetic breakers. The performance of this breaker contributes to the
reliability of the VX system.
In the VX 2400, current in excess of 20 amps in any single output will cause the channel breaker
to trip. In the VX 1200 the maximum is 10 amps, and the VX 3000 is 27 amps. The breaker toggle
will flip to the left, indicated on the front of the breaker as "OFF". If a breaker trips, it is an
indication of a problem on that load circuit. Reset the breaker only after finding and fixing the fault
that created the overload. Resetting the breaker repeatedly with a shorted output stresses the
breaker, the dimmer channel and load wiring.
Channel breakers can also be used to turn off a single circuit. Pushing the breaker toggle handle
to the "OFF" position will disconnect power to the dimmer circuit and load.
