MAIN BOARD
Adopted to ensure reliable performance
The main board is mainly composed of a central processing unit (CPU), a memory, an input/output (I/O) interface circuit, and a logic drive circuit etc., connected to peripheral equipment via the interface circuit. For the design of the circuit board, many reliable designs and anti-interference designs are adopted to ensure reliable performance of the EHAD dispenser. In the circuit design, many filtering components are used to ensure that the Fuel station can work normally for a long time in harsh environments.
EHAD L2 – Main Board is Subjected to IFSF(International Forecourt Standardisation Forum) – an international standard group of European Oil Societies(keepers of fuel pump stations) defining and publishing technology standards for pump station equipment in order to reach compatibility among devices of various producers.
One EHAD l2- Main board can be used to power One to Eight Nozzle Fuel Dispensers. The EHAD main board can self-diagnose and be easily updated.
The main board is the control core of the fuel dispenser, controlling all the functions of the fuel dispenser. Its working voltages are 5V and 12V DC power. Its output signals are motor and solenoid valve control signals, display signals, loudspeaker signals, etc .The program on the main board rectifies, computes, processes and saves various signals, produces various corresponding commands and control data ;And sends these commands and control data to peripheral board circuits, so the fuel dispenser works according to designated requirements.
The Strong Computing EHAD main board stores transaction on its build in memory. This is used to eliminate and problems with lost transactions during power failures or Fuel Management system lost connections. During a power or Fuel Management system lost connection, The CPU stores transactions and sends them once connections are regained.
