Dangers, Warnings and Precautions


"DANGER": means: If you do not follow the instructions, severe injury or death will occur.
“WARNING": means: If you do not follow the instructions, severe injury or death can occur.
"CAUTION": means: If you do not follow the instructions, damage can occur to the equipment.

“DANGER”: Disconnect all power to this equipment and associated dispensers equipment during installation, service or any maintenance. Failure to do so can cause injury or damage equipment.

“WARNING”: Maintenance and repairs must be done by QUALIFIED/TRAINED personnel.

“WARNING”: To prevent electric shock, keep the electrical parts of the console dry.

“WARNING”: You must have training in the installation and service of fuel dispensing equipment before working on this system.

“WARNING”: Make sure this equipment is correctly grounded. Failure to do so can cause injury or damage equipment.

“CAUTION”: Electronic components are static sensitive. Use proper static precautions (static straps) before working on the equipment.

“WARNING”: Failure to properly ground all equipment can cause injury or damage equipment.

“WARNING”: Installation must comply with National Code (NFPA #70), Automotive and Marine Service Code (NFPA #30A), Federal, State and local codes.

“CAUTION”: Each dispenser must have a 12 gauge or larger green stranded ground wire connected from the grounding lug of the junction box to the main electrical service panel ground. (National Electrical Code, Article 514-7). It is unacceptable to rely on the conduit for this grounding requirement.

M2E Wiring and Setup Instructions

M2E setup

The M2E is programmed at the factory with the required dispenser protocol. Bennett current loop, Bennett 485, Gilbarco, Tokheim, and Wayne are all programming options. The various dispenser protocols are set on the M2E board using jumpers. Details on jumper positions and the ability to program M2Es in the field will be available to dealers in the near future.

The M2E (Mechanical to Electronic) connects to all VR computers and converts the mechanical/electrical signals into an electronic protocol that can be read by modern day controllers such as the TMS EZ, Ruby, Gilbarco Passport, and Wayne Fusion POS systems. Virtually any POS system that controls Wayne, Gilbarco, Bennett, and Tokheim electronic dispensers can interface with the M2E. The M2E converts mechanical pulses into an electronic output and back again to seamlessly control any mechanical pump with an electronic pump controller. Currently, the Veeder Root computer must transmit money pulses into the M2E, but the appropriate pulser (100 pulses per dollar) must be used in conjunction with the Veeder Root computer to facilitate money pulses.

M2E to Controller Connections

Connection to the controller is made via a 6 position connector on the M2E. For sites with controllers connecting to electronic pumps via an electronic IC box (D, 100, 5000, Fusion, PIB, 515, or any TMS MPC, EZ or EZS IC box), the M2E will wire into that box. Bennett Loop and 485, Gilbarco and Wayne are all 2-wires loops. Tokheim uses 3-wires, and TMS-Direct (Mech only sites and no electronic IC box) uses 4-wires.

Protocol Pin Positions

If specified at the time of ordering the M2E the jumpers will be set at the factory. The settings are shown below.

M2E battery connections
Click to Enlarge

A 9-vold rechargeable battery is used to maintain communication to a controller in the event of power failure. The battery should be connected via the 2-position jumper at all times unless power to the TMS-78 power supply is deliberately turned off for an indefinite amount of time. Upon startup, move the jumper from the 3-pos. Prog./Run jumper to the 2 pos. Battery Jumper.

Setting the M2E to Manual Mode

No console control, always armed

Console vs. manual operation is set using a 2-pos. jumper. The M2E is shipped to operate in console control. Add a jumper (not included) to put the board in manual mode. Inserting the jumper makes the AUTH wire HOT at all times and there is no console control.

Addressing the M2E pump ID

Board Address is set using the 8-pos. dipswitch.

A ZERO indicates Dipswitch is OFF, a ONE indicated Dipswitch is ON. The board below is addressed as pump fueling position 1. Use the chart below to set the ID. The ID set determines communication to the controller.
