Note: If a low-voltage control bank is set to receive its brightness information from either ALSM2 or ALSM3, and then a pattern

generator is enabled for that Control Bank, the Control Bank will ignore the ALSM2 or ALSM3 zone target information. This prevents

conflicts from ALSM2/ALSM3 zone targets and ALS controlled pattern currents.
