Select
Access Level Required:
OPERATOR
This key is used to enter the slot numbers and the min-
imum and maximum Y-Axis values of each parameter
to be trended. Pressing this key places a yellow box
around Data Point 1 Slot Number. Use the ▲ and ▼
navigation keys to place the box around the value of
Data Points 1 through 6 to be changed. With the desired
value selected, press the

key. A dialog box is displayed
permitting data entry.
Data Point Slot # (1-6)
Access Level Required:
OPERATOR
Use the SELECT key as described above and enter the
slot number from the Common Slots Screen or Master
Slot Number List of the desired parameter to be trended.
The selected parameter description will be displayed
for the Data Point. Setting this slot number to zero will
disable trending for that particular Data Point. Any or
all points can be disabled.
Data Point Min (1-6)
Access Level Required: OPERATOR
Only displayed if the Associated Slot Number is not Zero.
This is the minimum value displayed for the Y-Axis. Se-
lecting a parameter for a Data Point sets this to the default
value, which is the lowest value allowed for that parameter.
It can be changed to a value that provides a more appro-
priate resolution for the parameter being monitored. To
change, use the SELECT key as described above and enter
the desired value. The value must always be set to a value
less than the Data Point Max. Otherwise, a red graph is
displayed on the Trend Screen with the words “ TREnD
MAX MUST BE > TREnD MIn
”. If the parameter
selected for this data point is a digital type (on/off), this
value must be set to zero (0). Zero indicates the OFF
state.
Data Point Max (1-6)
Access Level Required:
OPERATOR
Only displayed if the associated slot number is not zero.
This is the maximum value displayed for the Y-Axis. Se-
lecting a parameter for a Data Point sets this to the default
value, which is the highest value allowed for that parameter.
It can be changed to a value that provides a more appro-
priate resolution for the parameter being monitored. To
change, use the SELECT key as described above and enter
the desired value. The value must always be set to a value
greater than the Data Point Min. Otherwise, a red graph is
displayed on the Trend Screen with the words “TREND
MAX MUST BE > TREND MIN”. There are 20 Y-Axis
divisions. If a MIN-MAX span is selected that is not evenly
divided by 20, the Program will automatically select the
next higher MAX value that makes the span evenly divided
by 20 (If compressor application is other than “P”, ap-
plies only to Flash memory card version C.MLM.01.02
or later). For example, if 0.0 is selected as the MIN and
69.0 is selected as the MAX, the Program will insert 70.0
as the MAX value. If the parameter selected for this data
point is a digital type (on/off), this value must be set to one
(1). One indicates the on state.
