ERROR DISPLAY
DEFINITION
BLANK TAPE READ
A data block was not found during read forward within 25 feet (15 feet in GCR).
CHECK XXX SUPPLY
XXX = +5V, 15V or 6V. An out-of-tolerance condition has been detected with
the indicated power supply.
CONTROLLER ABORT
IFEN was pulsed false (the host aborted a read, write, or erase operation).
DENSITY LOCKED
An attempt was made to change density while the density was locked via the
configuration menu.
DOOR OPEN
The front door or top cover was opened while the tape was in motion.
EXEC.CHKSUM ERR.
A checksum error occurred in the WREX microcomputer during power-up or
manual diagnostics.
FILE PROTECT ERR
A write command was received while the tape was write-protected.
LOWLINE-HOLDING
The line voltage is too low to start tape motion. The tape drive will remain in this
state until the line voltage returns to the normal range.
LOW LINE VOLTS
Low line voltage. Message is cleared when condition disappears. Could also be
a +22 volt power supply problem.
MOTION CAL. FAIL
The Motion Calibrate procedure failed.
MOTION COMM.FAIL
Failure occurred in Motion DSP interboard communications during power-up or
manual diagnostics.
MOTN.CHKSUM ERR.
A checksum error occurred in the Motion microcomputer during power-up or
manual diagnostics.
NO ARA DETECTED
An ARA burst was not detected while reading a GCR tape from loadpoint.
NO ENV WHILE WRT
