Bennett 3000 Spec 300 Series Instruction Manual Product Introduction
12
PULSE OUTPUT BOARD (FLEET MANAGEMENT SYSTEMS)
Note: Used with Electronic Dispenser Models 3X11, 3X12, 3X22, X10DEF, and X20DEF where X is 7, 8, or 9.
The pulse output board connects to the 719 CPU on connector J7. It supports up to two fueling positions on the single RS485 connection.
The pulse output board interfaces with the fleet system using three signals. Refer to the programming section earlier in this manual to
configure Pulse Unit, Pulse Period (PPS), and Pulse Ratio.
1. Pulse Output – The pulse output allows the 3000 Series Mechanical interface to send pulse information to the Console and the Tank
Gauge. The system can be programmed to output pulse ratio from 1:1. 10:1. 100:1, and 1000:1. The fleet system and tank gauge
connected to the dispenser must provide 5 – 12 volts DC for the pulse output channel. Refer to the Programming Section to for pulse
output configuration.
2. Handle Switch Signal – The handle switch signal can be used to signal the console that the pump is “IN USE”. Some fleet systems
require this signal and some do not.
3. Authorization Signal – A fleet system can send authorization to a fueling point via a 110-volt signal that allows the fueling point to
reset at the beginning of the sale. Without this signal, the dispenser will not reset when in the “Mechanical” mode.
SATELLITE BOARD (OPTIONAL)
The Satellite Board is used to control the valve in the satellite unit and to receive handle signals from the satellite unit. This board is
located in the Master unit and the field wires to the valve and the handle from the satellite connects to this board. The optional satellite
“in use” light will illuminate when the satellite handle is raised.
3-PHASE CONTACTOR BOARD (OPTIONAL)
The contactor board is used for 3-Phase (380VAC) Suction Pump Motor Control. Self-contained dispensers have the pump motor
mounted in the lower hydraulic area. Power is passed to the pump motor using the pump motor relay located on the CPU board in the
electronic enclosure.
