Introduction
Purpose
This manual provides instructions for installing the Direct Pulse Out Interface Board
(M13949A001), which allows the pumps/dispensers to use both RS-485 and pulse out
interfaces for Atlas
board will only work with the Atlas 9852K or 9853K models and will not work with any other
model. This pulse output provides a DC output to indicate the quantity dispensed. The pulse
rate can be configured by a jumper setting for the rates of 1, 10, 100, 250, or 500 pulses per
gallon.

Direct Pulse Out Option Installation Instructions
for Atlas™ 9852K/9853K Pumps/Dispensers

™
9852K and 9853K pumps/dispensers. This direct pulse out interface
The output is an open collector transistor output capable of sinking up to 100 mi
voltages up to 24 VDC. The DC ground for the circuit comes from the Fuel Management
System (FMS). Since the transistor switches between ground and high-impedance, the
installer must provide a voltage reference when the transistor is in the high-impedance state.
This reference voltage is provided by a pull-up resistor installed at the FMS between the pulser
input and the reference voltage. The value of this resistor is calculated based on the voltage
and current requirements of the FMS pulser circuit.

Important Safety Information
The EMERGENCY STOP, ALL STOP, and
PUMP STOP buttons at the cashier’s station
WILL NOT shut off electrical power to the
pump/dispenser. This means that even if you
activate these stops, fuel may continue to flow
uncontrolled.
You must use the TOTAL ELECTRICAL
SHUT-OFF in the case of an emergency and not
the console’s ALL STOP and PUMP STOP or
similar keys.

WARNING
!
Notes: 1) Save this Important Safety Information section
in a readily accessible location.
2) Although DEF is non-flammable, Diesel is
flammable. Therefore, for DEF cabinets that are
attached to Diesel dispensers, follow all the
notes in this section that pertain to flammable
fuels.
This section introduces the hazards and safety precautions
associated with installing, inspecting, maintaining or servicing
this product. Before performing any task on this product, read
this safety information and the applicable sections in this
manual, where additional hazards and safety precautions for
your task will be found. Fire, explosion, electrical shock or
pressure release could occur and cause death or serious in jury,
if these safe service procedures are not followed.
Preliminary Precautions
You are working in a potentially dangerous environment of
flammable fuels, vapors, and high voltage or pressures. Only
trained or authorized individuals knowledgeable in the related
procedures should install, inspect, maintain or service this
equipment.
Emergency Total Electrical Shut-Off
The first and most important information you must know is how
to stop all fuel flow to the pump/dispenser and island. Locate
the switch or circuit breakers that shut off all power to all fueling
equipment, dispensing devices, and Submerged Turbine
Pumps (STPs).
Important Safety Information
Read the Manual
Read, understand and follow this manual and an y other labels
or related materials supplied with this equipment. If you do not
understand a procedure, call a Gasboy Authorized Serv ice
Contractor or call the Gasboy Service Center at
1-800-444-5529. It is imperative to your safety and the safety of
others to understand the procedures before beginning work.
Follow the Regulations
Applicable information is available in National Fire Protection
Association (NFPA) 30A; Code for Motor Fuel Dispensing
Facilities and Repair Garages, NFPA 70; National Electrical
Code (NEC), Occupational Safety and Health Administration
(OSHA) regulations and federal, state, and local codes. All
these regulations must be followed. Failure to install, inspect,
maintain or service this equipment in accordan ce with these
codes, regulations and standards may lead to legal ci tations
with penalties or affect the safe use and operation of the
equipment.
Replacement Parts
Use only genuine Gasboy replacement p art s and re trofit kits on
your pump/dispenser. Using parts other than genuine Gasboy
replacement parts could create a safety hazard and violate
local regulations.
Safety Symbols and Warning Words
This section provides important information about warning
symbols and boxes.
Alert Symbol
Total Electrical Shut-Off Before Access
Any procedure that requires access to electrical component s or
the electronics of the dispenser requires total electric al sh ut off
of that unit. Understand the function and location of this switch
or circuit breaker before inspecting, installing, maintaining, or
servicing Gasboy equipment.
Evacuating, Barricading and Shutting Off
Any procedure that requires access to the pump/dispenser or
STPs requires the following actions:
• An evacuation of all unauthorized persons and vehicles
from the work area
• Use of safety tape, cones o r ba rricades at the affected
unit(s)
• A total electrical shut-off of the affected unit(s)

This safety alert symbol is used in this manual and on
warning labels to alert you to a precaution which must be
followed to prevent potential personal safety hazards. Obey
safety directives that follow this symbol to avoid possible injury
or death.
Signal Words
These signal words used in this manual and on warning labels
tell you the seriousness of particular safety hazards. The
precautions below must be followed to prevent death, injury or
damage to the equipment:
DANGER: Alerts you to a hazard or unsafe practice
!
which will result in death or serious injury.
WARNING: Alerts you to a hazard or unsafe practice
!
that could result in death or serious injury.
CAUTION with Alert symbol: Designates a hazard or
!
unsafe practice which may re sult in minor injury.
CAUTION without Alert symbol: Designates a hazard
or unsafe practice which may result in property or
equipment damage.
Working With Fuels and Electrical Energy
Prevent Explosions and Fires
Fuels and their vapors will explode or burn, if ignited. Spilled or
leaking fuels cause vapors. Even filling customer tanks will
cause potentially dangerous vapors in the vicinity of the
dispenser or island.
DEF is non-flammable. Therefore, explosion and fire safety
warnings do not apply to DEF lines.
