Setting The Jumpers On The Pulse Output Board - Bennett 3700 Series Installation Manual

Setting the Jumpers on the Pulse Output Board

The Pulse Output board is ordered as an option with the Electronic 3000 series. This board is where the
field wires connect the 3rd party Fleet System to the Pulse Output functions of the dispenser. This
board also has jumpers that need to be set to determine the Pulse Rate and the Pulse Width. Whatever
pulse rate is set will send the same pulse rate and width to both the Fleet System and the Tank Gauge
(if one is connected). This section describes how to set these jumpers. Refer to the Figures below:
Figure 19 - Pulse Output Board
This is the Pulse Output Board. It has the terminal
strips for the field wire connections along the bottom
of the board to communicate with the Fleet System
using a pump handle output signal, an authorize in-
put signal and a pulse train signal. The Jumper
Header JP1 is at the top left of the board. These
jumpers must be set to determine the pulse rate and
the pulse width. See information below.
To set the Pulse Rate Output, set jumpers JP1-1 and JP1-2 as follows:
JP1-1 JP1-2 Pulses Per Gallon
OUT OUT 1000
IN OUT 100
OUT IN 10
IN IN 1
To set Pulse Width, set jumpers JP1-3, JP1-4, JP1-5 as follows (PULSE WIDTH'S ARE IN
MILLISECONDS):

JP1-1,2,3,4,and 5 are used to set the pulse rate and pulse width.
The top left of the Pulse Output board has a
jumper header called JP1. It has 8 jumper
positions. Set the Pulse Rate with the first two
jumpers and the Pulse Width with the 3rd, 4th
and 5th. See information below.
