This key is used to enter the slot numbers and the minimum and maximum Y-Axis values of each param- eter 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 ‘4’ (Enter) key. A dialog box is displayed permitting data entry.

Data Point Slot # (1-6)

Use the SELECT key as described above and enter the slot number from the Trend Common Slots Screen 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)

Only displayed if the Associated Slot Number is not Zero. This is the minimum value displayed for the Y-Axis. Selecting 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 appropriate 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)

Only displayed if the associated slot number is not zero. This is the maximum value displayed for the Y-Axis. Selecting 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 appropriate 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 20Y-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. For example, if 0.0 is selected as the MIN, and 69.0 as the MAX, the Program will insert

70.0as 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.
