LED display
The LED‘s are only used to provide the operator with a better display of the status
of each of the activated valve outputs. Its display is simply an enlarged and detailed
depiction of the function of the arrow symbols on the LC display.
The LED display is particularly useful when the operator is at a great distance from
the controller and if the sun is strong.
