Check the pump no-quantity transaction (NQN) count in the diagnostics
printout, using the command PRINT DIAGNOSTICS 8. If there are several
NQNs, try to determine the cause or consult your service representative.
If a pulser unit or attached cables have failed, fuel can flow until the pump times
out, but no gallons or dollars will be recorded.
To re-enable a pump that has been disabled because of too many zero-quantity
transactions, after first identifying and correcting the cause, type the command
ENABLE PUMP.
To reset the NQN counters for all pumps back to zero, give the command
ENABLE PUMP;I. Wait until no fuel transactions are in progress.
Pump #X Disabled, No Price
The SC III has disabled the pump because no price or price code has been
assigned for that pump.
Use PRINT PUMP to determine if a price code has been assigned to the pump.
If one has, then use PRINT PRICE to see if a price has been assigned to that
code for level 0 and for the level for each method of payment that is accepted. If
a price is missing for that code or for some needed level, use LOAD PRICE to
load it.
If no price code has been assigned to the hose, then use LOAD FUEL to assign
a price code to the pump. (Some sites may choose to assign a product that has a
price to the pump instead of a price code, if multi-level prices for cash, credit,
etc., are not needed.)

No action is required.
Pump Control Unit #X Came Up
