The channel ON/OFF assignments for the NXC-VAI4 are described in the following table.

Off = 50% voltage, and all channel assignments are mutually exclusive.

NXC-VAI4 Channel Assignments

Channel State Function
Channel 1 ON While channel 1 is ON, the voltage on Output 1 will ramp up at the "CURRENT
OUTPUT 1 RAMP UP TIME" rate. The voltage ramp stops if the maximum is reached.
OFF Stops voltage ramping on Output 1 at current value.
Channel 2 ON While channel 2 is ON, the voltage on Output 2 will ramp up at the "CURRENT
OUTPUT 2 RAMP UP TIME" rate. The voltage ramp stops if the maximum is reached.
OFF Stops voltage ramping on Output 2 at current value.
Channel 3 ON While channel 3 is ON, the voltage on Output 3 will ramp up at the "CURRENT
OUTPUT 3 RAMP UP TIME" rate. The voltage ramp stops if the maximum is reached.
OFF Stops voltage ramping on Output 3 at current value.
Channel 4 ON While channel 4 is ON, the voltage on Output 4 will ramp up at the "CURRENT
OUTPUT 4 RAMP UP TIME" rate. The voltage ramp stops if the maximum is reached.
OFF Stops voltage ramping on Output 4 at current value.
Channel 5 ON While channel 5 is ON, the voltage on Output 1 will ramp down at the "CURRENT
OUTPUT 1 RAMP DOWN TIME" rate. The voltage ramp stops if the minimum is
reached.
OFF Stops voltage ramping on Output 1 at current value.
Channel 6 ON While channel 6 is ON, the voltage on Output 2 will ramp down at the "CURRENT
OUTPUT 2 RAMP DOWN TIME" rate. The voltage ramp stops if the minimum is
reached.
OFF Stops voltage ramping on Output 2 at current value.
Channel 7 ON While channel 7 is ON, the voltage on Output 3 will ramp down at the "CURRENT
OUTPUT 3 RAMP DOWN TIME" rate. The voltage ramp stops if the minimum is
reached.
OFF Stops voltage ramping on Output 3 at current value.
Channel 8 ON While channel 8 is ON, the voltage on Output 4 will ramp down at the "CURRENT
OUTPUT 4 RAMP DOWN TIME" rate. The voltage ramp stops if the minimum is
reached.
OFF Stops voltage ramping on Output 4 at current value.
Channel 9 ON Reserved [do not use]
OFF Reserved [do not use]
Channel 10 ON While channel 10 is ON, the voltage on Output 1 is set to 100%
OFF Sets Output 1 voltage to 50%.
Channel 11 ON While channel 11 is ON, the voltage on Output 2 is set to 100%
OFF Sets Output 2 voltage to 50%.
Channel 12 ON While channel 12 is ON, the voltage on Output 3 is set to 100%
OFF Sets Output 3 voltage to 50%.
Channel 13 ON While channel 13 is ON, the voltage on Output 4 is set to 100%
OFF Sets Output 4 voltage to 50%.
Channel 14 ON While channel 14 is ON, the voltage on Output 1 is set to 0%
OFF Sets Output 1 voltage to 50%.
Channel 15 ON While channel 15 is ON, the voltage on Output 2 is set to 0%
OFF Sets Output 2 voltage to 50%.
Channel 16 ON While channel 16 is ON, the voltage on Output 3 is set to 0%
OFF Sets Output 3 voltage to 50%.
