2.3.2 Reading LEDs – setting values (Multi/ MultiPlus)
The value of a setting can be determined on the basis of the following formula:
Value set = setting number * scale + offset
The ‘offset’ and the ‘scale’ are specified for each setting.
The setting number is indicated as follows via the LEDs:
The LEDs are divided into 2 columns of 4 LEDs each.
Each column indicates the numbers 0 - 9.
These columns together indicate 2-digit numbers.
The left column indicates the left-hand digit. The right-hand column shows the
right-hand digit.
The digit in a column can be determined by adding the separate ‘LED values’.
A flashing LED counts as 1 and an illuminated LED as 2.
A special case is 4 flashing LEDs. This signifies a 9.

The increments can be smaller than the reading (scale value). In that case, a pushbutton
should be pressed repeatedly before the LED indication changes.
