9.3 Trend in BB (Base Block)
The Trend in BB option allows the user to enable the DLS4 to log trending data when the drive is Base
Blocked (not running). By default, this opt
ion is disabled. By enabling this option, the Trend’s circular
buffer will fill up faster, causing old Trend data to be overwritten sooner.
9.4 Clear Trends
The Trending data logs can be cleared with this option. With “Clear Trends” on the top line, press the
ENTER key and a confirmation dialog will appear on the screen. To cancel this action, choose the “No”
option by pressing the F1 key or the ESC key. To confirm this action and clear the trending logs, choose
the “Yes” option by pressing the F2 key. A “Clearing Trends” message will appear on the display, and a
number indicating how many trend files have been erased. There may be hundreds of trend files, so this
step may take a while.
9.1 Custom Monitors
The Custom Monitors allow the user to indicate specific monitors that should get logged in the Trending
data. A maximum of 10 monitors may be selected. If the user attempts to select more than 10 monitors, a
“Max of 10 Monitors” message will appear on the display. This menu is the first option located within the
“Trending” section. A dot/diamond indicates that the corresponding monitor will get logged in the trending
data.
Follow these steps to enable or disable a custom monitor:
1. Select Trending and press Enter.
2. Press Enter again to select Custom Monitors.
3. Use arrows to scroll through available monitors until desired monitor appears above dotted line.
4. Press Enter so a dot/diamond appears next to parameter.
5. Press ESC to save changes.
The added monitor will now be included in a Trend file after a Run is captured while connected to a drive.
The following page in this manual lists the various custom monitors available for each supported drive.
