SECTION 2: PRODUCT INTRODUCTION
The pulser assembly is a dual phase electronic pulser that pulses at a rate of 256 pulses per revolution. These pulsers are physically
mounted to the output shaft of the Bennett SB-100 meter. Note: There is one pulser for every meter. As fuel flows through the meter,
the output shaft rotates and turns the pulser. Approximately 8 rotations of the meter represent 1 gallon of fuel.
FEATURES
Pulses at a rate of 256 pulses per revolution or roughly 1024 pulses per gallon
Optically coupled device and outputs 2-separate phases of square wave pulses
Operate off a regulated +5-volt DC signal.
Intrinsically safe for use in Class 1, Division 1, Group D hazardous locations when used in conjunction with Bennett Dispensers.
Pulses in tenths, hundredths, or cents depending on dispenser programming.
Pulse “weight” can be adjusted in Bennett electronics for electronic calibration of the dispenser.
The Pulser Barrier Boards are covered by a plastic cover. Always replace the cover after servicing the equipment.

SECTION 3: INSTALLATION INSTRUCTIONS
Bennett Pump Dispensers are to be installed by trained technicians. All technicians must be aware of ALL safety instructions. If you are
not a Bennett trained technician, please contact Bennett Technical Support at 1-800-423-6638 for training information.
HOW TO REMOVE PULSER COVER
Remove the Pulser cover and set aside. Retain screws for reuse.
Note:
After installation is complete, replace cover using the screws provided.
The “Sealed” pulser cover shown below is optional. If it is present, please check the requirements by the AHJ to put the pump
back into service.
HOW TO MOUNT THE PULSER ASSEMBLY
The Pulser Assembly measures 4” x 2” x 2””. Each Pulser requires two mounting screws for the mount, and 2 mounting screws for the
cover to the mount.
1. Mount Pulser by aligning roll pin in coupler slot.
2. Mount bracket screws to the top of the meter cover using the screws provided. Tighten firmly.
3. After the pulser is mounted and installation is complete, replace cover and seal if necessary.
HOW TO CONNECT PULSERS
CAUTION: WHEN CONNECTING A PULSER NEVER CONNECT A PULSER OR DISCONNECT A PULSER WITHOUT TURNING OFF
THE DISPENSER POWER AND BATTERY. DAMAGE TO THE PULSER OR THE LOWER I/O BOARD CAN OCCUR IF
POWER IS LEFT ON.
MOUNTING HOLE
MOUNTING HOLE
1. Seal Wire is Thread thru the
Meter Collector cover bolts,
then up to the bolt
connecting the cover to the
meter top.
2. The seal wire then threads
from the pulser cover through
the standoffs holding the
pulser
3. After the Seal Wire is thread
through both pulser mounting
standoffs, is routed back down to
the Meter mounting adaptor.

The pulsers connect to the Lower I/O board through a ribbon cable in a daisy chain fashion. All of the pulsers for side 1 connect to J2 on
the Lower I/O board and if applicable pulsers for side 2 connect to J1 on the Lower I/O Board. Note: The ribbon cable has notches so the
cable cannot be put on backwards.
Pulser for Product A plugs directly into the Lower I/O Board
J2 = Lower I/O Board
J3 = Pulser B
Pulser for Product B plugs directly into Product A’s Pulser
J2 = Pulser A
J3 = Shunt on Pins 13-14
IMPORTANT: Jumper must be in place on the last pulser in series
for any for pulser to work properly.
Bennett Pulser Assembly Instruction Manual Installation Introduction
11
HOW TO OPERATE THE PULSER
The pulser information is carried on a ribbon cable that connects the pulser to the barrier circuit. The ribbon
cable runs through a potted conduit between the upper portion (electronics area - high voltage) section of the
dispenser to the lower portion (hydraulics area - low voltage) section of the dispenser.
The ribbon cable connects to pulser connector J2 to the first pulser in the loop. Usually this is the “A” product.
If there is more than pulser then another ribbon cable connects from the first pulser J3 (back) connector to
the next pulser J2 (front) connector and it works like this for the remaining pulsers except for the last pulser
for that side in the loop.
Note: On the last pulser, a jumper must be placed across the last set of pins on J3 to identify that pulser as the
last pulser in the loop.

Bennett Pulser Assembly Instruction Manual Diagnostics & Troubleshooting

SECTION 4: DIAGNOSTICS & TROUBLESHOOTING
This section describes the information provided on each diagnostic display message. Note: Displays shown throughout the manual are
examples only. Information may vary based on dispenser options.
DIAGNOSTICS
Error checking - The dual phase pulsers allow for error checking. One phase is used to check the other. For example, after pumping 1 gallon
of fuel the CPU should see approximately 1024 pulses from each phase. There is a built in diagnostic where if the CPU sees more than 26
consecutive missing pulses from one or the other of the phases it will stop the sale and post an error message on the display of the side of
the dispenser with the error. Errors are stored in a diagnostic history file and any error that occurs can be cleared by removing and replacing
the nozzle from the nozzle boot, or lifting and lowering the lever if it is set up in the Lever Option.
