Introduction
Features and Capabilities
Summary Description

6123919 Rev C 5-17-18
The Manager’s Keypad (see figure 1).
The manager’s keypad allows the dispenser to be programmed. When
the keypad is plugged into the dispenser receptacle the dispenser
automatically enters the attendant mode (sometimes referred to as
“manager’s mode”). The attendant mode allows access to the
dispenser totals, pricing information and programming information.
The manager keypad is located in the electronics head behind the side
1 door. See page 18 for instructions on how to connect the manager’s
keypad.
See the “How To Prepare The Dispenser For Operation” section for a
complete description of keypad functions for programming the
dispenser. See the “How To Operate The Dispenser” section for an
explanation of keypad use to read totals. See the “How To Use
Diagnostics” section for complete instructions for using the keypad to
read error codes.
9. Two battery back-up systems are provided:
A +12 volt DC sealed lead acid battery works in conjunction with the Totals/Display Recall switch to
display the last sale data or pump totals when AC power is interrupted. The battery will allow the
displays to be viewed in 30-second intervals for a total of up to 20 minutes.
A +3.6 volt DC nickel-cadmium battery retains totals and programmed information in the RAM
memory during power failures for up to 10 days.
10. All units have conformal coated electronic boards to help protect them from moisture or foreign
material damage. All major electronic board assemblies are environmentally tested and
temperature cycled.
11. Dispenser programming is performed from the manager’s keypad. The keypad is located inside the
electronics head behind side 1 electronics door.
FOR CNG INSTALLATIONS:
Note: It is REQUIRED that a pressure regulator is installed at the dispenser if there is no other
device to limit pressure at the dispenser.
Note: Pressure at the dispenser must not exceed 4250PSI.

7123919 Rev C 5-17-18
The Error Messages (see figure 5).
When an error message appears, there is a fault
condition in the dispenser. Use the dispenser
diagnostics to determine the problem. Please refer to
page 53 “How to Use Diagnostics”.
NOTE: When an error message appears the
dispenser can be reset by turning any pump
handle on and back off.
The Power Failure Message (see figure 6).
The Power Fail message occurs when the power has
been interrupted or turned off to the dispenser. If the
power is turned off and the P Fail message does not
appear, the charge is low on the 12-volt battery.
Replace the battery. Failure to replace the battery could
result in loss of dispenser electronic totals and stand
alone operating data.
Totals Switch (see figure 7).
The totals switch is a magnetic reed switch. The switch
is located directly behind the “mass units” screen on the
Main Display Area (see figure 7).
To enter the totals mode hold the black Access Magnet
over the “mass units” print beside the Main Display. This
will display all Mode 1, Mode 2, and Mode 26 shift totals.
Once the totals mode is entered, the next totals are
displayed “tapping” the magnet over the “mass units”
print beside the Main Display. By successively “tapping”
over the “mass units” print, all totals can be displayed. If
the magnet is not “tapped” over the “mass units” print for
30 seconds, the display returns to idle. See Menu Code
1 and 26 for more information.
NOTE: If a pump handle is turned on during this
operation, the display returns to idle.
The Last Sale Recall Switch (see figure 7).
The Last Sale Recall switch is similar to the Totals
Switch except it is placed behind the Total Sale Text
(Sale $). If power to the dispenser is interrupted, the
money and mass totals can be accessed, as well as the
current sale information. Just hold it over the Total Sale
Text (Sale $) for approximately 2 seconds. The last sale
in progress will display for 20 seconds. Holding the
magnet over the Total Sale Text (Sale$) successively
will bring up the last sale information every 20 seconds.
For complete information, see “How to Retrieve The Last
Sale During a Power Failure,” Page 16.

How to Read the Electro-mechanical Totalizer
The dispenser is equipped with a Electro-mechanical
totalizer for each meter, which records the mass
dispensed for each sale. The mass recorded is an
accumulative total that cannot be reset. The total is
cumulative and reads in whole unit (DGE) increments
(see figure D-5).
NOTE: Because of rounding methods used and the
nature of electronic totals versus an analog
device such as an electro-mechanical totalizer,
electronic totals of Menu Code 01 and electro-
mechanical totals will rarely match exactly.
Mode 2 totals can be programmed to match the electro-
mechanical totalizers, and they will continue to track
exactly until a cold start occurs.

Connecting the Manager’s keypad for dispenser
programming.
Programming is done from the manager’s keypad
located inside the electronics compartment behind the
side 1 electronics door. (see figure P1).
NOTE: Make sure the nozzle is in the Nozzle Boot
prior to operation. If the nozzle is out of the
Nozzle Boot the dispenser will not go into
programming mode.
To enable the dispenser for programming:
1. Remove the keyboard from the plastic bag located
on the inside of the electronic enclosure.
2. Locate the keyboard receptacle located on the
product select keyboard, which is located on the
backside of side 1 electronic door. The plug
receptacle is labeled “Keyboard” and is located on
the right side of the product select keyboard (see
figure P2).
3. Plug the manager’s keypad into the receptacle
observing the plug polarity.
4. When the Manager’s keypad is properly connected
the dispenser will automatically enter the managers
programming mode. The dispenser’s display will
read ”Enter side 1”.
5. Press the Enter Button on the Manager’s keypad.
At this point the dispenser will go into Manager’s
Mode,
6. When the programming session is complete,
remove the keypad from the receptacle and restore
the keypad to its holder for future programming
sessions. When the manager’s keypad is removed
from the receptacle the dispenser will automatically
enter the operating mode.
NOTE: The electrical Enclosure must stay
pressurized at all times. Once the door is opened a
pressure switch will force the power to be removed
from the electronics, leaving it impossible to
program with the door opened. As soon as the
keypad is plugged into the auxiliary backlight board
the door must be closed immediately. Make sure
that the manager’s keypad is draped over the door
and accessible from outside the dispenser when
closing and locking the door.

SUGGESTED SETUP SEQUENCE
To program the dispenser’s memory for the first time or following a RAM memory clear, follow the menu
codes in order as they are listed in the Initial Setup sequence below. Each Menu Code can be pro-
grammed individually. However, in order for the dispenser to operate properly, the initial setup program-
ming sequence must be followed. If not, the dispenser may not operate properly because of default set-
tings or no data programmed. However, the Menu Codes are explained in the operator’s manual in nu-
merical order. Make sure the initial setup menu codes are programmed before testing dispenser opera-
tions. Failure to do so may result in equipment malfunction.
