TABLE OF CONTENTS

TMS MPC-162 SYSTEM DESCRIPTION

The TMS MPC-162 system is designed to control Tokheim Model 162 electronic pumps/dispensers. MPC Systems are sold in 8 or 16 fueling position configurations, and are capable of controlling any combination of 162, 262A, TCS, TCSA, and Premier pumps/dispensers (up to four grades per side). This includes blend style pumps/dispensers, and all can be controlled from a single IC box. In addition, the MPC console, when configured as a HYBRID, can simultaneously control mechanical pumps/dispensers via the standard TMS-800F interconnect box. Figure 1, on page 2, shows a TMS MPC-162 system diagram with one Tokheim MPD and 162 connected.

NOTE: The TMS MPC electronic control systems DO NOT INTERFACE with Tokheim MMDs or NON-A versions of the 262.

A system for controlling from one to four 162 fueling positions consists of an MPC console, MPC cable, and a main TMS MPC-162 Interconnect Box. The main IC Box can hold two MPC-96 pump cards, and each MPC-TM96 pump card can control two 162 fueling positions.

For sites with five to twelve 162 fueling positions, a TMS MPC-162 Pump Card IC Box (holds up to four pump cards) is required in addition to the system described above.

A site with thirteen to sixteen 162 fueling positions requires a second Pump Card IC Box (three IC boxes in all), that holds the remaining MPC-TM96 pump cards (up to two).

The standard cable (from console to interconnect box) furnished with the MPC console system is 25 feet long. Optional cable lengths of 50, 75, 100, and 150 feet are available, and can be used in place of the standard length cable.

MPC consoles can control MPDs with a maximum of 4 grades per side. The maximum number of fueling positions permissible per MPC system is 8 for an MPC-8, or 16 for an MPC-16, where each side of an MPD (no matter how many grades) counts as one fueling position.

To control a combination of Tokheim 162, 262A, and TCS, TCSA, or Premier B, EB, B3 Blend style pumps/dispensers, OPTIONAL MPC-TM93 pump card(s) (2 max.) must be plugged into the MPC-TM97 communication board in the main TMS MPC-162 IC Box as shown in Fig. 2. Each MPC-TM93 allows up to four sets of data wire connections (communicates with four pumps/dispensers).

To control mechanical as well as electronic pumps/dispensers, the MPC console must be ordered configured as a HYBRID. Also required is an 800F mechanical control IC box, a TMS-47 mechanical cable, and one TMS-23 relay board per fueling position.

When ordering a system, list the number and the style of dispensers being controlled, and TMS will ship the required components.

TMS MPC-162 MAIN INTERCONNECT BOX DESCRIPTION

The main TMS MPC-162 Interconnect Box includes, on the outside, a TOGGLE SWITCH, and on the inside, a MPC-TM97 communication board, a MPC-TM98 distribution board, a MPC-TM99 power supply, and can hold two MPC-96 pump cards, and two MPC-TM93 pump cards.

MPC-TM96: These pump cards are the "brains" for the Tokheim 162 dispensers. They receive handle and pulse signals from the 162 dispensers, control the 162 valves and pump motor, and send the data that shows the sale amounts at the pump and on the console.

MPC-TM97: This communication board/power supply receives the incoming line voltage, supplies the system with AC and DC voltage, transmits data signals between the console and the MPC-TM96 boards, allows the connection of "smart" pumps/dispensers (if optional MPC-TM93 boards are installed), and has a relay that is de-activated by pressing the Emergency Off button or turning the OFF/ON key switch to the OFF position (see number fourteen of the "Important Notes" section for the Emergency Off description).

MPC-TM98: This distribution board allows connection of the MPC-TM96 pump cards and TMS MPC-162 Pump Card Boxes to the main IC box, and carries data signals from the MPC-TM97 to all MPC-TM96's.

MPC-TM99: This power supply contains a transformer, a 12vdc battery, and circuit breakers for the AC input voltage (1/2- amp) and the 12vdc output voltage (2-amp).

NOTE: In the event of power failure, or whenever AC power to the system is turned off, the 12vdc battery must be disconnected to prevent unnecessary power drain. There are two methods of disconnecting the battery:

1. If the MPC console is connected, turning the OFF/ON key switch to the OFF position automatically disconnects the battery.

2. In STAND ALONE (no console) operation, the TOGGLE SWITCH on the outside of the Main IC Box disconnects the battery circuit. Turn the switch to the "STAND ALONE OFF" / "CONSOLE CONTROL" position whenever AC power is turned off, or in the event of power failure (after all sales have been completed). Refer to Fig 2 on page five.

TOGGLE SWITCH: Located on the outside of the main MPC-162 IC box, this switch disconnects the battery circuit when a MPC console has been disconnected. Normally, this switch should be turned to the "STAND ALONE OFF" or "CONSOLE CONTROL" position. When operating without a console, the switch should be turned to "STAND ALONE" to supply +12vdc to the displays in the event of power failure.

REMEMBER: While running in stand alone, turn the TOGGLE SWITCH to the "STAND ALONE OFF" or "CONSOLE CONTROL" position if power is removed from the system (after all sales have been completed).

MPC-TM93: These OPTIONAL pump cards control Tokheim 262A, TCS, TCSA, and Premier (up to four grades per fueling position), including blend style, pumps/dispensers. MPC-TM93 pump cards (2 max.) are plugged into the MPC-TM97 communication board in the sockets provided as shown in Fig. 2. Each MPC-TM93 allows connections of up to four pumps/dispensers.

TMS MPC-162 PUMP CARD BOX DESCRIPTION

The TMS MPC-162 Pump Card Box includes a MPC-TM98 distribution board, and can hold four MPC-96 pump cards.

HYBRID MPC CONSOLE WITH TWO MECHANICAL INTERFACE BOARDS:

A sixteen fueling position hybrid MPC console with two mechanical IF Boards allows addressing of mechanical pumps/dispensers to one through sixteen (1-16), providing two TM-47 mechanical cables and 800F IC Boxes are present.

Refer to figure Z to connect TMS-47 mechanical cables to a hybrid MPC console with two mechanical IF Boards.

NOTE: Select the correct cable connector for the desired mechanical fueling position number. The cable connector marked as "1" is the first available position, and "8" is the last. For sites with mechanical pumps/dispensers addressed as fueling positions nine through sixteen, cable connector "1" corresponds to fueling position nine (9), and "8" corresponds to position sixteen (16).

Attach fueling positions 1-8 and 1-6 to each IF board

Figure 3. Hybrid console with two mechanical IF boards (click to enlarge)

HOW TO INSTALL OR REPLACE INDIVIDUAL MPC-TM96 PUMP CARDS

Each MPC-TM96 pump card is held in place with two screws on the outside edge and the pin connector on the inside edge. Exercise care when replacing MPC-TM96 pump cards to prevent damage to the connector and or pins.

HOW TO CONNECT TMS MPC-162 INTERCONNECT BOXES TOGETHER

Connect the IC boxes with +12v to +12v and GND to GND

Figure 4. TMS MPC-162 IC Box Connection Diagram (click to enlarge)

Use five 22 gauge or larger wires when making connections between the Main MPC-162 IC Box and the MPC-162 Pump Card Boxes. Make connections as shown in figure 3, with +12V to +12V, GND to GND, etc.

PROGRAMMING THE MPC-TM96 PUMP CARD

Each MPC-TM96 pump card can control two fueling positions, and each fueling position on the pump card is designated as either A or B (for programming purposes only). Figure 4 shows a description of the programming switches. For correct operation, each fueling position must be setup on a pump card as follows:

"ADDR" (Address) - There are sixteen available fueling positions, 0 thru 9, and A thru F. Use the rotary switch labeled ADDR, and the following chart to assign a fueling position number to each 162 pump/dispenser.

Fueling position to fuel pump/ dispenser chart: 1-10 = 0-9, 11-16= A-F

"PROG" (Program) - Select the desired operation for each fueling position in use by setting the four position dip-switch.

NOTE: LEAK TEST delays activation of the valves for three seconds to allow connection of leak detectors.

With a fueling position connected, and being controlled by the MPC console, the dip switch should be set as follows:

1 = ON (ON LINE)
2 = ON (CONSOLE CONTROL)
3 = ON or OFF (LEAK TEST - optional)
4 = not used

With a fueling position connected, but running in STAND ALONE, the dip switch should be set as follows:

1 = ON (ON LINE)
2 = OFF (STAND ALONE)
3 = ON or OFF (LEAK TEST -optional)
4 = not used

NOTE: WHEN RUNNING IN STAND ALONE, THE PRICE IS SET AT THE MPC-TM96 PUMP CARD USING THE PRICE ROTARY SWITCHES.

When a fueling position is not connected, the dip switch should be set as follows:

1 = OFF (OFF LINE)
2 = OFF (STAND ALONE)
3 = OFF (NO LEAK TEST)
4 = not used

"PRICE" (Price) - The price per gallon must be set at the MPC-TM96 pump card only if STAND ALONE operation has been selected on the four position dip switch. Refer to figure 5 and use the rotary switches labeled PRICE to program the price per gallon for each fueling position in STAND ALONE operation.

Figure 5. MPC-TM96 Pump Card Switch Description (click to enlarge)

IMPORTANT NOTES:

1. All +12vdc, GND, HANDLE, PULSER, DATA, and SYNC wires connections between the MPC-TM96 pump cards and the dispensers must be 18 gauge or larger.

2. All AC wires including MOTOR, SLOW, FAST, and AC HOT must be 14 gauge or larger.

3. Use cable ties to keep the data cable in place from the console to the interconnect box if conduit is not used.

4. If the MPC cable is put through a conduit, use 2" minimum to allow room for the connectors on the cable. Do not cut connectors from the MPC cable to use smaller conduit. Do not put MPC cable conduit underground. MPC data cables are not designed to operate under these conditions and will not be covered under warranty.

5. Do not use wire nuts on any grounding connections. Make all connections with compression connectors (crimp or split lug).

6. If the console or dispenser power comes from a sub-panel, all ground wires must end at the main electrical service panel ground.

7. There must be no more than 1 ohm resistance between Neutral and Earth Ground.

8. Do not use old or used wire for dispenser wire connections.

9. Use rigid metal conduit only. Do not use PVC conduit.

10. Do not route mercury vapor, canopy light wiring, or other unrelated wiring through the dispenser wiring conduit.

11. Auxiliary relays or contactors MUST BE used in the motor circuit! Refer to the installation manual of the dispenser for complete installation requirements, drawings, and special notes.

12. Wiring for dispensers, TMS MPC-162 IC box, and other control boxes should all be on the same phase from the service panel, or erratic operation/communication could result.

13. In the interest of everyone's safety, all persons involved in the operation of this system should be made aware of a proper power-down sequence for all components used to dispense flammable products.

14. The EMERGENCY OFF connector supplies a dry contact relay closure across COM. and N.O. while console is on and not in "EMER OFF" condition. While console is turned OFF via the OFF/ON key, and/or during the time the "EMER OFF" button has been pressed so that the "EMER OFF" light is flashing, the connector supplies an open circuit across COM and N.O. Figure 5 shows the Emergency Off connector located in the main TMS MPC-162 IC Box.

START-UP PROCEDURE:

1. Confirm all equipment has been properly installed and grounded.

2. Apply power to the pump/dispensers after Consulting the installation guide for the equipment being installed.

3. Set the "smart" pumps/dispensers so that:

a. The communication is set for VISION, MEMS IV, MEMS V, and the 83 DHC. b. Slow flow setting set at pump (F18). c. MODE F19 is set to console control. d. MODE F23 is set with the desired address and pricing structure.

NOTE: If a problem exists with the pumps/dispensers, contact the equipment distributor, or the manufacturer's customer service department.

4. The TMS MPC Console CAN send the blend ratio to the pump/dispenser. Set the premier blender pump/dispenser's MODE F26 at 1 so it will accept the console's blend ratio.

REMEMBER: This is only a suggestion and does not limit the programming required for TOKHEIM pumps/dispensers to operate correctly.

5. Apply power to the MPC system.

6. Turn the MPC console OFF/ON key switch to the on (horizontal) position.

7. Use the PROGRAMMING INSTRUCTIONS FOR MPC CONTROLLERS to program the console.

NOTE: PPPPPP.PP in the display window after the key has been turned on, indicates a power problem. Confirm all connections are correct, and that the breaker is switched to the on position. If problem persists, contact the equipment distributor, or the fuel control service department at Triangle Microsystems (TMS), Raleigh, NC. at 1-800-334-5548.

TURNING THE SYSTEM OFF:

It is not recommended or necessary to turn OFF the dedicated system breaker that supplies power to the MPC-TM97 board during the time the store/station is closed. Simply turning the console OFF/ON key to the OFF position after all hoses have been de-authorized, along with following the dispenser power down sequence, will prevent fuel from being dispensed.

IN CASE OF EMERGENCY:

In an emergency situation that requires one or more pump/dispensers to be turned OFF, push the "EMER OFF" button on the front of the MPC Console ("EMER OFF" light blinks). This causes two things to happen:

1. A "turn OFF" signal is sent to every pump/dispenser. 2. The EMERGENCY OFF relay on the MPC-TM92 board is deactivated (goes to "normal" condition).

To return to normal operation, push the "EMER OFF" button again ('EMER OFF" light goes out). Two things will happen:

1. A "Resume pumping" signal will be sent to each pump that was originally pumping (and not yet hung up). 2. The EMERGENCY OFF relay will be activated
