Interlock
This pin enables or disables the operation of the device, even when the PLC mode is not
active. Setting this pin to LOW (0) will enable all operations on the device, including LCD
input and PLC control mode. Setting this pin to HIGH (1) will disable all operations on
the device, including stopping any exposure operations currently taking place.

Example Setup
The following is an example of how to set up the
BlueWave QX4
LED Head Controls to
operate individually.
1.
Set your individual LED Head channels to the desired power level and
exposure time. LED Head channels that will use an external PLC control for
exposure time should be programmed to zero time.
2.
Connect the PLC Sense and GND from the external PLC DC power to the GND
connection of the
BlueWave QX4
input. This will put the Controller into PLC
control mode.
3.
Connect the + voltage from the PLC (through the dropping resistor) to the
applicable channel input connection.
NOTE:
Separate dropping resistors should be used from voltage to each
channel input.
