An “
S
” appearing in display line one indicates that the command was received before
the tape drive reinstruct window closed, allowing the tape to stream. Loading a tape
clears the command log.
On SCSI models, this function does not display the commands that were transferred
via the SCSI bus, but displays the commands that were transferred from the SCSI
PCBA to the WREX PCBA.

AC Line Voltage Function
The
AC LINE VOLTAGE
function presents a sixteen-segment bar graph on the liquid
crystal display. The bar graph is shown in Figure 4-4.
Line voltage low but acceptable.
Line voltage high and should be checked.
Line voltage unacceptably low.
LOW LINE VOLTS
Figure 4-4 AC Line Voltage Display
The bar graph provides a visual indication of the AC line voltage with respect to the
tape drive's minimum and maximum line voltage requirements. When the tape
drive's AC line voltage configuration switches at the rear of the drive are correctly
set for the available line voltage, about half of the segments in the bar graph will be
