AUTOMATIC TEST: This test assumes that the pump/dispenser resets in manual as described
above. Place the pump override switch in the ON position for the duration
of the problem.
Possible Cause Checks Corrective Action
PPC CPU board MODE
switches are set wrong. Make sure the MODE
switches (SC-1 through SC-4)
on the PPC CPU board are
set properly. If pump is wired for use with a
postpay-prepay console, the
MODE switches (SC-1
through SC-4) should be set
for Reset Complete Mode.
Site controller configured to
not wait for switch detect on
console transactions. Check that all mechanical
pumps are configured to wait
for switch detect on console
transactions. For SC I, clear bit 3 at Table
24 offset 18+((pump number -
1) x 4). This is automatic for
SC II.
No relay drive from PPC CPU
board. Check if the MAIN and AUX
relay drive LED's on the
CMOS Pump Control CPU
board; or if the SUB, SLOW,
and FAST relay drive LED's
on the EXPMUX CPU board
turn on when the pump is
activated from the card reader
or terminal. Replace the PPC CPU board
if all of the appropriate relay
drive LED's do not turn on.
