NOTICE
Using the enclosed connecting cable
Only use the connecting cable (10 m) shipped with the product to connect the floodlight.
Floodlights are suitable for permanent operation as well as switching operation.
You can control the brightness using the potentiometer or the analog VC input.
• Brightness control using the potentiometer:
All the way to the left = 0%; all the way to the right = 100% brightness
Make sure that the brightness control using the potentiometer is disabled when the
voltage at VC is greater than 1 V DC.
• Optional brightness control using the analog VC input:
VC (Pin D, yellow) = 2 V DC ... 10 V DC
Note that the potentiometer must always be turned all the way to the left for this.
All relevant information for connecting and operating the external floodlight can be found in
the Product Information shipped with the product.
