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.
