TL-130200-1001File ManagementWhen loading the FMS files into the system, certain errors may
System (FMS) Errorsbe received. For example,“FMS error 14” is received. This
means that FILE D is not available for creation, for opening, or for
seizure. Refer to Table 3.1 for status code and explanation.

4.0 Maintenance commands are input via the maintenance
terminal to designate particular parts of the system hardware as
“maintenance busy” so that system software will not try to use
that hardware during system operation. Hardware is out of
service when designated as maintenance busy. That piece of
hardware becomes available for maintenance...

TL-130200-1001Attendant Console4.6 The memory of each CEC provides an area called the fault
Code Display Faultlog which records system faults. It records the last 32 faults
detected. When a fault is detected, the ALARM LED on each
Attendant Console flashes, indicating that a fault has occurred.
Each console displays all faults reported in the fault log
independently of the other consoles in the system. All of the
faults listed on the fault log are displayed by repeated
depressions of the ALARM...

TL-130200-1001Fault Code 00Description:
Block Parity FailureWhen a program is loaded into the system, the CPU85 willgenerate block parity for each 256 bytes of instruction data and
static data. This is done by an exclusive OR of the data table.
Periodically, the CPU85 will recalculate the block parity andcompare it with the value calculated earlier (detect memory
failures and data mutilation).

TL-130200-1001Fault Code 01Description:
Dynamic RAM MemoryThe system tests dynamic memory. A block of five bytes is put
into a temporary storage area. A series of test patterns is read
into the area of memory being tested and then verified. The data
is returned to its original location and the test advances to the
next five bytes of dynamic memory (interrupts are disabled during
this test).
