9.9 Adjustable parameters

SLC and DLC pump control panels include an easy-to-use programmable logic unit that incorporates many timing and logic functions.
The unit has been programmed at the factory for the control functions required. The unit includes adjustable operational parameters and
viewable monitoring information. Some operational parameters may need changing for your particular application.
SLC and DLC pump control panels use block names to identify the various parameters (please refer to the screen of the logic controller
face inside the enclosure).
