Document conventions

• Abbreviations and acronyms in this manual are spelled out in the glossary. The
glossary also contains definitions of important terms.
• Push button navigation in the LHMI menu structure is presented by using the
push button icons.
For example, to navigate between the options, use
• HMI menu paths are presented in bold.
For example, select Main menu/Settings.
• LHMI messages are shown in Courier font.
For example, to save the changes in non-volatile memory, select Yes and
press .
• Parameter names are shown in italics.
For example, the function can be enabled and disabled with the Operation
setting.
• Each function block symbol shows the available input/output signal.
• the character ^ in front of an input/output signal name indicates that the
signal name may be customized using the PCM600 software.
• the character * after an input signal name indicates that the signal must
be connected to another function block in the application configuration
to achieve a valid application configuration.
• Dimensions are provided both in inches and millimeters. If it is not specifically
mentioned then the dimension is in millimeters.
• Logic diagrams describe the signal logic of the function block and are
bordered by dashed lines.
In a logic diagram, input and output signal paths are shown as lines that touch
the outer border of the diagram. Input signals are always on the left-hand side
and output signals are on the right-hand side.
Input and output signals can be configured using PCM600. They can be
connected to the inputs and outputs of other functions and to binary inputs and
outputs. Examples of input signals are BLKTR, BLOCK, and VTSZ.
Examples of output signals are TRIP, START, STL1, STL2, and STL3.
• Frames with a shaded area on the right-hand side represent setting
parameters. These parameters can only be set via the PST or LHMI.
Their values are high (1) only when the corresponding setting parameter
is set to the symbolic value specified within the frame. Example is the
signal Timer tPP=On. Their logical values correspond automatically to
the selected setting value.
• Internal signals are illustrated graphically and end approximately 2 mm
from the frame edge. If an internal signal path cannot be drawn with a
continuous line, the same signal name is used where the signal should
continue, see figure
BLK.
• Signal paths that extend beyond the logic diagram and continue in
another diagram will be approximately 2 mm from the frame edge, see
figure 3 and figure 4. Examples are STNDL1N, STNDL2N, STNDL3N,
STNDL1L2, STNDL2L3, and STNDL3L1.
