Function Definition of the 5-Pin Wiring Connector on the TMS-23 Relay Board

  1. PULSAR COMMON: This terminal is connected directly to earth in the TMS power supply.
  2. PULSER SIGNAL: This terminal is connected to a resistor network in the console. When the pulser contacts are open the voltage will be +6 VDC referenced to earth. Pulser wires must not be connected to any other wires, terminals, or switches.
  3. VALVE: This terminal in connected to Neutral through the fast flow relay.
  4. MR (in use): This terminal is the VAC "Hot" return after the reset cycles.
  5. AUTH: This terminal is the Authorize; it provides 115 VAC "Hot" to the reset motor. This terminal also detects the call signal when the handle at the pump is switched "on".

WARNING!!!

  • If the MR or AUTH wire is connected to Neutral or earth ground, the relay board will be damaged (these are 115 VAC "Hot" wires)
  • If the Pulser Common or Valve wire is connected to a VAC "Hot" wire, the relay board will be damaged.
  • If the Pulser Signal wire is connected to a VAC "Hot" wire, the console will be damaged.
  • Mis-wiring the power supply input or output wires will result in resistor burn-out on the power supply.
  • The valves must be connected to MR for 115 VAC "Hot". Do not connect valves to L1 out.
  • Do not attempt to operate preset or prepay sales unless the pump is properly equipped with fast andslow flow valves as shown.
  • If the console display window shows PPPPPP.PP when the key is turned on it means no power is being supplied to the console; do not leave the key on because it will discharge the battery.

INSTALLATION GUIDE

  1. Select the proper wiring diagram from the enclosed drawings.
  2. Disconnect the cable from the console for wiring and pump tests.
  3. Mount the relay interconnect box near the wire trough or conduit from the pumps.
  4. For each hose:
    Connect the pump control wires to the interconnect relay board
    Recheck the wiring for proper hook-up, opens, shorts, etc.
    With the circuit breaker off, connect power to the relay board from the circuit breaker
    Place the console/bypass slide switch on the relay board in the bypass position.
    Turn on the circuit breaker. Confirm that the hose will reset and dispense product
    Place the console/bypass slide switch in the console position; confirm that the hose will notreset or dispense
  5. Connect the console cable to the console.
  6. Connect power from a DEDICATED BREAKER to the console power supply in the relay box.
  7. Turn the console key on; console should display "00" in the Mode and Amount windows.
  8. Enter the product prices and test each hose for proper operation (see the Operators Guide.)

After all installation and testing is complete, perform a "ram clear" on the console; this clears the memory of all programming and accumulating totals, and gets rid of any "glitches" that may have been picked up (if the console is equipped with a manager's key, it must be "on" for this procedure).

  • Turn the power key "off"
  • Press and hold "0" on the keypad while turning the power key "on"
  • Continue holding "0" until "00" appears in the Mode and Amount windows. This takes about 12 seconds for an 800F Standard console, and about 3 seconds for a Plus or an MPC console
  • Program the console according to instructions in the OPERATORS GUIDE.

800F POWER SUPPLY

The 800F power supply is mounted in the relay box next to the door hinge. The black 3-terminal input strip should be connected to the main power distribution box with a dedicated breaker and 3 dedicated wires for VAC "hot", neutral, and earth ground. Output voltages are unfiltered and may vary 20&#;37 without affecting equipment.

PULSERS

TMS systems that control mechanical pumps and dispensers are designed to operate with contact closure type pulsers; 5 VDC is supplied to the pulsing circuits by the TMS system. For retail applications, these systems must be used with pulsers that transmit 1 pulse per penny of product dispensed.

TMS equipment will not work with Gilbarco pulsers on mechanical dispensers. Gilbarco mechanical dispensers must be equipped with pulsers as described below to work properly with TMS controllers.

There are a number of acceptable pulsers on the market.Veeder-Root Series 1871 and Series 7697 Pulse Transmitters are widely used with TMS systems, as are Western Electronics Model 400-B and Model 500 pulsers.

Regardless of the pulser used, the two most important points are:

  • it must transmit 1 pulse per penny of product dispensed.
  • there must be no voltage across the output leads other than the 5 VDC supplied by the TMS system.

The 800F Standard console had been tested without error at a puse rate of 3600 pulses per minute. The 800F Plus and MPC consoles have been tested without error at 8500 pulses per minute.

SPECIAL WIRING FOR DUAL HOSE, SINGLE PRODUCT SUCTION PUMP

Some dual hose, single product suction pumps made by Gilbarco and other manufacturers have oversized (3/4 hp) pumping motors. The high starting current on these motors, especially when the supply voltage is low, may cause the TMS relay contacts to stick. Wiring as shown below will prevent the motor from running continuously. the only difference between this and other TMS wiring diagrams is that the "L1 OUT" wire goes through a switch in the electric reset on its way to the pumping motor.

TMS-800F SERVICE PRACTICE

TMS-800F systems are designed to be serviced by unit exchange. The exchange units are: consoles, relay board, and power supply board. All service and installation vehicles are expected to carry exchange units. During the warranty period these units may be returned to Triangle MicroSystems, Inc. freight prepaid. They will be repaired and returned freight prepaid at no charge.

THE TMS WARRANTY DOES NOT COVER TRAVEL AND LABOR CHARGES

SERVICE AND OPERATING CONSIDERATIONS

Static Electricity

Occasionally cashiers will stand on throw rugs or carpets which can cause static shocks when they touch the TMS-800F console. This is caused by rubber sole shoes on carpets (not the console) . It can be corrected by spraying the carpet with anti-static spray (available at most carpet stores) or by removing the carpet.

BALLPOINT PEN ON KEYBOARD

The keyboard should not be punched with a ballpoint pen or pencil. This can cause a permanent dent in the overlay and eventually cause the "AUTH" key to stay on. This requires on overlay replacement.

A charge will apply to replace damaged overlays.

CONSOLE CABLE CONNECTOR

The cable connector can be broken if the cable is pulled out of the console at one end and then twisted out. This connector should be pulled out straight (both ends equally).

A charge will apply to repair cables with broken connectors!

RELAY BOARD CONNECTOR

When disconnecting the cable connector from the relay box, please pull on the connector (not the wires). Pulling the wires can cause failure.

WESTERN ELECTRONIC PULSER

Many TMS distributors use Western Electronic pulsers with TMS-800F-1 control systems. These pulsers seem to work well and are easy to install.

If you used the Western pulser, make the 115 VAC power connection to neutral and MR. DO NOT connect the "AUTH" wire; this may cause a false "CALL" indication to the console.

TWO-WAY VALVES (VEEDER-ROOT OR SKINNER)

Use the following diagram for wiring two-way (double-action) valves to the TMS-800F control systems:

INSTALLER DAMAGED CONSOLE WHEN REPLACING VEEDER-ROOT EQUIPMENT

some TMS consoles have been damaged during installation replacing Veeder-Root equipment. Veeder-Root has 115 VAC on the pulser leads (connected in the pump junction box.)

Notice the TMS diagram has no AC connection the pulser leads. Check the pulser leads before applying power.

THIS TYPE OF DAMAGE IS NOT COVERD UNDER WARRANTY!

INSTALLER DAMAGED RELAY BOARD

Relay boards are sometimes damaged by installers making connections to shorted wires.

This damage can be avoided by checking the wires before energizing. Another way to avoid this problem is to temporarily connect the "AUTH" wire directly to the "L1 in" wire for pump checkout. With this connection, a shorted wire will trip the breaker without damaging anything.

If a relay board is accidentally damaged, it can be repaired by soldering a jumper to the replace the burned printed circuit conductor.
