EIU Control
EIUs may be programmed for Prokee
®
and/or keypad input through a laptop or Customer Satisfaction
Center connection to the controlling master FMU. Activation options are: 1) through use of a Prokee
®
only,
2) through use of an ID number only, or 3) through use of both a Prokee
®
and an ID number. Since it can be
programmed for ID number only input, a vehicle operator can activate the EIU without a Prokee
®
(that may
be on a key ring with his ignition keys). As such, it would be convenient to mount the EIU where vehicle
operators may roll down a window and activate it without leaving the vehicle (like a drive-thru ATM). Like the
FMUs,the option to input P.I.N. numbers may also be selected.
EIUs have a red LED over the Prokee
®
receptacle. If the EIU has power and is communicating to a
controlling master FMU, the red LED is constant on. If the EIU has power but has lost communications to
the controlling master FMU, the red LED is flashing. When the EIU is activated with a Prokee
®
and/or
keypad input, the red LED flashes for the duration of the momentary output to the controlled device, then
returns to constant on.
Accessory (Gate/Door/Carwash) Control through an EIU. The EIU does not power the
device (i.e., gate, door, carwash, etc.) it is connected to for full activation. The EIU provides a momentary
activation signal to another controlling device (i.e., gate controller). This activation signal can be set to: 1, 5,
8, 11, 14, 17, and 20 seconds. Ensure the controller can be set to receive a momentary input for activation.
The EIU controls accessory equipment in much the same manner as the FMUs control dispensers. The
accessory controller has a power lead to a momentary closed relay which when closed supplies power to
the accessory controller. The momentary closed relay may otherwise be activated by a push-button,
pressure sensor, motion sensor, remote controller, etc. This circuit is broken so the power lead to the
momentary close relay is brought to the EIU. When the EIU is activated, it sends a power signal to the
momentary closed relay to activate the accessory controller.
Redundant FMUs
There have been some requests to install two FMUs for redundant (duplicate) control of fuel dispensers.
This way either FMU can control all dispensers if one of the FMUs fails for any reason. This is not a good
plan. Maintaining inventory can become very confusing when transactions for each fueling hose are mixed
between two FMUs.
If redundancy is desired, and two FMUs are in the plans, then it is suggested redundancy be planned for by
duplicating products for each FMU. Then, if one FMU should fail, the other FMU will provide the same
products. Such an application might have an unleaded and diesel dispenser connected to FMU #1, and
another unleaded and diesel dispenser connected to FMU #2.
Central Accounting Office Requirements
The Central Accounting Office contains the equipment necessary to load the FuelMaster
®
Fuel
Management Software and administer a software operating program to manage an automated fueling site.
The same operating program created with the FuelMaster
®
Fuel Management Software can be used to
manage fixed and mobile, and passive and non-passive FMUs.
The Central Accounting Office will contain a Central Controller (a personal computer for running the Fuel
Management Software) and the peripherals such as the Prokee
®
/Smartcard Encoder, reports printer, and
equipment necessary to establish communications with the FMUs. The Central Controller need not
be a PC
dedicated to the management of the fueling site. It may be a shared PC used by the Central Controller
operator for other applications.
All Central Accounting Office equipment may be positioned at a single computer workstation. The
equipment should be located where it can be easily accessed without interfering with other daily duties of
office personnel. The computer workstation should have access to AC power receptacles and a compatible
235
