TM-18 teat code when entered via EFR/EF sequence shall cause
the DAMS to request one word of data from the computer via ODR/OA sequence. The data word when
received shall be stored in Buffer A.
The DAMS shall then circulate 16 bits of this data word through
the drum data paths and byte putty logic and place the circulated data in Buffer B.
The Data word in Buffer B shall then be transferred to the Com-
puter via IDR/IA control. Following the acknowledgement of the IDR data transfer, the DAMS shall
send the error count word to the computer via EI/IA control sequence.
(13) TM-13 Drum Status - This test mode shall verify the drum
fault status Signals with the exception of the MDM temperature shutdown status by simulating the
l xistence of a fault on the drum status line to the drum fault registers in the instruction status logic.
Upon receipt of the TM-13 instruction code via the EFR/EF
sequence, the DAMS shall cause the drum to simulate a fault on all the drum status lines. The active
drum fault status lines shall cause all drum fault registers to set. The DAMS shall then generate an
EI reporting an instruction status word for computer verification of the drum fault status bits.
(14) TM-14 Temperature Error Shutdown - TM-14
shall verify proper operation of the shutdown circuit in the DAMS and Logic Unit 4.
The test shall be initiated by means of an instruction word from
the computer using EFR/EF contro1.
The drum shall generate a speed error condition which shall
cause the shutdown of drum motor drive power. The DAMS shall then send the instruction status word
to the computer with EI/I4 control.
The DAMS shall then send a simulated temperature shutdown
error signal to the temperature shutdown logic. This logic shall then time out a delay of about three
seconds and shut down all rower to the drum. The instruction status word shall again be sent to the
computer with an EI/IA. -
Recovery from this test shall be accomplished by the computer
sending either a Master Clear or Read/Write Terminate instruction to the DAMS using an "E F with
force".
