• 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
and .
• 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 2 and figure 3 . Example of the
internal signal is 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.
