54 Pump Control Unit Pump Interface Manual v1.3
Gasboy CFN Series 03/20/03
DIP Switch Bank C
Note: In connection with pulser enabled, there are two error codes, each with three characters,
that can show up in the error column on a transaction printout. The reset-failed-to-start
transaction code is $D2 through $DF, and the reset-failed-to-complete transaction code is $E5
through $EF ($ indicates hexadecimal). The last character in each code (2 through F or 5 through
F) is the number of seconds the PCU waited for reset to start or complete. This numeric character
is incremented by one each time the PCU reset-to-start/complete times out, until the maximum
time-out of 15 (15 is F in hexadecimal counting) seconds is reached.
Test Mode. When test mode is activated with switch C-8, switch C-5 determines the relay limits:
In test mode, switches C-6 and C-7 select the pump to be tested:
