6. For dispensers without a lever on nozzle boot, skip this step . Operator will lift lever on nozzle boot to begin fueling.
7. Dispenser control system will initiate the fueling protocol. Throughout the process, the control system will receive data
from the thermocouples and pressure transmitters adjust the flow of hydrogen accordingly to prevent over-heating
and over-pressurization. See Dispenser Control System, below, for more details on the fueling protocol.
8. Once fueling is complete, operator will remove the nozzle from vehicle and replace in nozzle boot. Once the nozzle has
been placed back in the nozzle boot, air will be blown over the nozzle to remove condensation build-up.
9. At this point, the operator will receive a message on the payment screen telling them the fueling process has been
completed.

DISPENSER CONTROL SYSTEM
The proprietary fueling control system was developed by Bennett to monitor critical process parameters during the fueling
process, as specified in SAE J2601, and will either maintain those parameters within the required limits or apply the necessary
fail-safe measures should the limits be exceeded. Once authorization is received from the P.O.S., the dispenser will initiate the
fueling process.
An overview of the fueling process is illustrated in Figure 3.2 .
Figure 3.2: Summary of hydrogen fueling process.
STARTUP TIME
During startup, the dispenser will perform a connection pulse and initial leak check.
CONNECTION PULSE: The connection pulse allows the dispenser to equalize pressure with the CHSS in order to measure the
initial pressure in the tank under static conditions.
