Bennett CDIM Cable Connections The Bennett Pump Interface supports single product dispensing with Horizon 9400 Series dispenser models,when an active two-wire loop is available for communications listening to the dispenser communications volume information.The information collected by the interface allows TLS-350R Business Inventory Reconciliation to compare tank totals to fuel transaction for end of day,end of shift,or end of month,running variances.This particular Interface solution for Bennett dispensing equipment requires one CAB per dispenser communications loop.Typically one or two loops are required for a single dispenser having two fueling positions.For this reason the Interface kit includes two CAB(s)with supportive cabling. Supportive cabling required is sold in lengths,which are identified in the last three digits of the kit form number.The length requirement is determined by the distance measured from the dispenser communication loop termination to the TLS-350R console. National Electrical Code Compliance The following information is for general reference and is not intended to replace recommended National Electrical Code procedures.It is important for the installer to understand that electrical equipment and wiring located in Class I,Division 1 and 2 installations shall comply with the latest appropriate Articles found in the National Electric Code(NFPA 70)and the Automotive and Marine Service Station Code(NFPA 30A). Connecting the Bennett CAB to the Dispenser Current Loop 1. Locate dispenser two-wire loop termination points,typically a screw type terminal strip located with-in a box mounted close to the fueling equipment on the wall.Typical boxes which include loop termination: • Bennett Pump Interface Box-Fuelomat(see Figure 6). • Bennett Pump Terminal Strip Box 1-16, 17-36(see Figure 7). • Bennett Pump Interconnect Box Model 405E(see Figure 8). 2. Looking at the terminal strip where all dispenser field wiring terminate for 2-wire loop communications,determine the number of loops that are in operation.Two conductors labeled(+)positive and(-)negative are considered a single loop starting from the number one position of the terminal strip.Each loop found will require a single Veeder-Root CAB.A single kit includes two CAB which supports two loops.You may find that a loop can support one or two dispensers,this will depend mostly on the installation practices of the equipment in your area. 3. Get the 2-wire shielded cable(P/N 331105-001)from the kit which has a 3-connector plug on one end and stripped wire on the other.If necessary,trim off the shield/drain wire at the stripped wire end of the cable because it is not used. a. Attach the 3-conductor plug end of the cable to the PUMP COMM connector(on right side)of the CAB(ref.Figure 3 on page 7). b. Route other end of the cable with the stripped ends to the dispenser loop termination point within the Bennett dispenser distribution box. c. Check that the CAB's RUN/BYPASS switch is in the RUN position(ref.Figure 3 on page 7).If necessary set switch to RUN. (Note:when switch is in"BYPASS"the status LED will be ON,when switch is in"RUN"the LED will flash when pump communications are present). 4. Complete all fueling transactions in process.Important:Do not disconnect the dispenser communication wiring during a customer transaction because doing so may result in a loss of dispenser data.It may also cause the dispenser controller system to hang up. Do not start any new transactions until the following connections are made.Select loop consisting of positive(+)orange and a negative(-)yellow wire.Remove the positive(+)orange wire and use a wire nut(576008-461)to connect it to the positive(+) white wire from the CAB.Complete the loop by attaching the negative(-)black wire from the CAB to the positive(+)position on the terminal strip.Dispenser communications should resume. 5. Repeat this process for each loop and CAB. 11
