OVERVIEW
As many as six Operator selected parameters (Data
Points) can be plotted in an X/Y graph format. The
X-Axis is scaled per the selected Data Collection In-
terval and displayed in a time of day or elapsed time
format, as selected with the X-Axis TOGGLE key. The
Y-Axis is scaled for each parameter per the selected
minimum and maximum value for each parameter.
Analog parameters are scaled in pressure, temperature,
volts, amps, hertz or time. Digital on/off parameters
are scaled as zero (off) and one (on). Only one Y-Axis
label is displayed at a time. The Y-Axis TOGGLE Key
is used to toggle the Y-Axis labels through the different
parameters. The Y-Axis label that is being displayed
is identified at the top of the graph. For identification,
each plotted parameter and associated Y-Axis labeling
is color coordinated.
On compressor applications other than “P” compres-
sors, if equipped with Flash Memory Card version
C.MLM.01.04.xxx and earlier, all trended Data Points
are displayed simultaneously. On all “P” compres-
sor applications or other compressor applications
that are equipped with Flash Memory Card version
C.MLM.01.05.xxx and later, the DATA SELECT key
is used to display all trended Data Points simultane-
ously or select a single Data Point for display.
The parameters are sampled at the selected Data Col-
lection Interval and plotted using 450 data points across
the X-Axis. If the actual value of the sampled param-
eter is less than the Y-Axis label minimum for that
parameter, the value will be plotted at the minimum
value. Similarly, if the actual value is greater than the
Y-Axis label maximum for that parameter, the value
will be plotted at the maximum value.
There are three types of charts that can be created: One
Screen, Continuous or Triggered (not applicable to Flash
Memory Card version C.MLM.01.04.xxx and earlier).
When plotting reaches the end of the X-Axis, if one screen
is selected, trending stops and data is frozen. If continuous
is selected, the oldest data is dropped from the left-hand
side of the graph at the next collection interval. Thereaf-
ter, the oldest data is dropped from the left hand-side of
the graph at each data collection interval. If triggered is
selected, data collection can be set to start or stop based
upon the selected Trigger Action (start or stop). If start
is selected, data collection will not begin until the trig-
gers have been satisfied and any selected trigger delay has
elapsed. Data collection will stop at the completion of one
screen of data as with the one screen. If stop is selected,
data collection will not stop until the triggers have been
satisfied and any selected trigger delay has elapsed.
