Microlok II System Startup, Troubleshooting, and Maintenance UNION SWITCH & SIGNAL
SM-6800C Rev. 2.5 September 2000 4-23
The oldest entry always appears at the top of the list. All more recent entries scroll downward as
they are retrieved from the Microlok II unit. The log will finish downloading when the most
recent entry has been received.
The Freeze/Resume, Clear, Reload and Start/End Time buttons at the top of the display control the
operation of the data logger:
• Freeze enables you pause while downloading data from the User Data Log. After you have
paused the display, the Freeze pushbutton changes to Resume. You then can click on the
Resume button to resume downloading data.
• Clear removes all of the currently recorded indications from the log and restarts the updating
process. The selected events/variables in the list remain unchanged. Before you can clear the
log, the system issues a confirmation box to verify that you want to remove the indications
from the user data log. An example of the confirmation box is shown below. Click on
Yes to
clear the log or No to return to the log display.
• Reload returns to the oldest event and begins the downloading process again.
• Start/End Time returns to the previous screen to allow the user to specify a new starting and
ending time for downloading the User Data Log.
To return to the Maintenance Tools main menu from the user data log display, click on the Back
button on the tool bar.
NOTE:
The User Data Log can be downloaded to the maintenance tool as before. If
the PC Card is in the write-protect mode (to maintain the data on the card),
data can only be retrieved if the application on the controller board matches
the one stored on the Card.
The User Data Log cannot be cleared if the Card is write-protected.
