Part No. 920559 Rev H November 2008
4.3 Basic Dispenser Requirements
Unit prices must be set and the dispenser must be authorized for the dispenser to operate. If the
dispenser is connected to a control system, each dispenser must have a unique fueling point
number set for communication with the system as discussed in Section 3.
If the dispenser is connected to a 2400 MCS, Wayne Plus or Nucleus POS system and you want
to operate the dispenser in the stand-alone mode, independently from the control system, per-
form the following steps:
1. Move the Authorize switch on the dispenser to the full service position.
2. If the dispenser is not equipped with the Authorize switch, jumper J7 on the Unit Price Display
board must be installed. See Appendix C for details.
3. Access function programming and set the Filling Mode to Stand-alone, as explained in Sec-
tion 4.9.
4.4 Operating the Dispenser
1. Authorize the dispenser via the Authorize switch on the dispenser or via the control system.
2. Remove the nozzle from the nozzle boot for either the blended hose or the single product
hose. The nozzle boot switch will turn on. The unit price displays of the product(s) not
selected will show dashes. If the blending hose is selected, the lighted grade selection but-
tons for the blending products will blink until a grade selection button is pressed; if the sin-
gle product hose is selected, the lighted grade selection button for the single product will
blink until it is pressed.
3. Push a grade selection button for the desired product to select one of the products from the
blending hose, or the one product from the single product hose. The dispenser will reset
and prepare for delivery. The sale display will show all eights, then blanks, then the money
and volume portion of the display will reset to zero. The unit prices not selected will be
blank or show dashes. The grade selection button that was pressed will be steadily lit; the
others will be dark. The correct submersible pump(s) will start at the beginning of the reset
cycle and the solenoid valve(s) will open approximately three seconds later. Product selec-
tion can be changed any time before product flow is sensed by the computer.
4. Dispense product. (Pressing the optional Stop button will stop product flow only. The nozzle
boot switch must be cycled and the dispenser must then be reset before that side of the
dispenser can continue operation.)
5. Return the nozzle to the nozzle boot. The nozzle boot switch will turn off; the sale will be com-
plete and ready to pay.
NOTE: NFPA 30A requires the dispenser to be “manually activated.” This requires a separate intentional operation
(Push to Start, Cash/Credit selection, or grade selection) after the nozzle is removed from its hang up position.
