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
PPU CPU board switches are
set wrong. Make sure the MODE
switches (SC-1 through SC-4)
on the PPC CPU board are
set properly. If a pump is wired for use with
a postpay-prepay console, the
MODE switches 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.
Normal Mode
No relay drive from PPC CPU
board. Activate the pump from the
card reader or terminal.
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. Replace the PPC CPU board
if all of the appropriate relay
drive LED's do not turn on.
Reset Complete Mode
No switch detect. Turn the pump handle on and
measure for 115VAC at the
AUX switch detect contacts at
TBS on the PPC I/O board.
Check that the switch detect
LED on the PPC I/O board
turns on.
If 115VAC is not measured,
repair the wiring between the
pump and PPC.
If the switch detect LED does
not turn on, replace the PPC
I/O board.
No relay drive from PPC CPU
board. Activate the pump from the
console. Check if the relay
LED's on the PPC CPU board
turn on. Replace the PPC CPU board
if the relay drive LED's do not
turn on.
