occurred.
Make sure that power is supplied to the PSC Control Card.
Make sure that the PSC7000 Control Card and power
supply are securely mounted into the PSC backplane.
If PSC Control Card reset does not work, replace the
PSC7000 Control Card.

Autorun
Not
Working
PSC7000 has just
completed auto reset
after a bus error, or a
hardware failure has
occurred.
1) Check whether the system variable
(AutorunPermissi
o
n@) is FALSE. When it is TRUE (see
Step 3 below), turn on the PSC7000 Control Card.
2) Reset the error on the PSC terminal, or perform download
from CF, so the AutorunPermissi
o
n@ should become
TRUE, and autorun will be enabled. Note that download
from the PSC terminal will not work.
3) When the system switch is in the neutral position
(Enable), make sure that the system variable
(AUTORUN@@) is TRUE.
If it indicates FALSE, replace the motherboard of the
PSC7000 Control Card.
4) If the PSC7000 Control Card is not activated when power
is turned off and back on again, replace the DSP
module.
