Preset quantities or costs may only be set with credit card transactions. The transaction is
started with both the fast and slow valves turned on. When the setpoint is reached, the fast valve
shuts off and the transaction is finished on the slow valve.
With Prokee
®
s and smartcards, the transaction is also started with both the fast and slow valves
turned on, but the transaction ends with the transaction limit encoded into the Prokee
®
or
smartcard. When the setpoint is reached, the fast valve shuts off and the transaction is finished
on the slow valve.
The relay assemblies may be 50 amp solid state or dual control, and they may be mixed (one 50
amp solid state, and one dual control relay assembly). Unless specified otherwise, all FMUs built
for small airport or marina applications have two dual control relay assemblies installed.
This control method does not prevent dispenser reset and pump motor activation before
authorization. Pump handle detection is possible from all FMU models.
Perform the following:
1) Verify two relay assemblies are installed in the FMU, and corresponding auto/manual
switches are installed for all hoses to be controlled on both relay assemblies.
WARNING
Failure to remove dispenser power at the circuit breaker panel may result in electrical shock.
AVERTISSEMENT
Omettre d'enlever un distributeur de courant au panneau de disjoncteurs peut entraîner un choc électrique.
2) Remove dispenser power at the circuit breaker panel.
NOTE
Figure 4-12 shows one output from the dispenser reset mechanism powering both valves. Some
dispensers/dispensing systems will have two outputs, one for each stage of the valve. Dispensers with
separate outputs to each valve stage may be influenced by CPU programming. If possible, use the output to
the slow stage. The slow stage remains active from start to finish in each transaction. The FMU will use its
programming to shut off the fast stage.
3) A two-stage valve will have two electrical inputs, one for the slow side of the valve (usually a
yellow wire) and one for the fast side of the valve (usually a black wire), plus a neutral
(usually a red wire). Locate the two valve inputs and identify them as slow or fast.
4) Run three wires from the FMU to the dispenser junction box: one for a dispenser reset
complete input, one for VALVE HOT (SLOW), and one for VALVE HOT (FAST).
5) In the FMU, connect one wire to LN1, one wire to LD1, and one wire to LD5.
6) Connect a jumper wire from LN1 to LN5.
7) In the dispenser, disconnect the inputs to the fast and slow side of the two-stage valve.
8) Connect the wire running from LN1 to dispenser RESET COMPLETE.
9) Connect the wire running from LD1 to the VALVE HOT (SLOW) wire (usually a yellow wire).
10) Connect the wire running from LD5 to the VALVE HOT (FAST) wire (usually a black wire).
11) Repeat steps 2 through 10, as required, for all additional hoses.
12) Using a laptop or Customer Satisfaction Center connection via Procomm or Hyperterminal to
the FMU (see Appendix D):
a) Enable the TWO RELAYS PER PUMP option using the 59 command.
b) Set the setpoint for each hose using the 57 command.
c) (Optional) Enable DISPLAY PUMP PRICING using 59 command. This will display price
per gallon for each configured hose when the A key on the keypad is depressed.
d) (Optional) Enable PRINT DOLLAR FOR PROKEE RECEIPTS using 5B command. This
will display hose position, product, sale amount (in dollars), and quantity of last fuel
transaction on the FMU display.
e) (Optional) Set duration of display for PRINT DOLLAR FOR PROKEE RECEIPTS using
260
