  • Page 2 WARNINGS, CAUTIONS AND NOTES Throughout this manual you will see WARNINGS, CAUTIONS and NOTES. They are here for your benefit and warrant attention. By paying careful attention to them you can prevent injury and possible equipment damage. Below are examples: WARNINGS: INFORM THE READER OF POSSIBLE BODILY INJURY IF PROCEDURES ARE NOT FOLLOWED EXACTLY.
  • Page 3 ATTENTION - OBSERVE PRE- CAUTIONS FOR HANDLING ELECTROSTATIC SENSITIVE DEVICES. Caution - This electronic device is sensitive to damage from ESD (electro- static discharge). Observe the following precautions when servicing this device. 1. Always use a static-dissipative wrist strap. Connect the strap to a grounded, conduc- tive surface or to the metal chassis of the equipment under repair.

  • Page 7 1.2. Pulse Output Units (2400S Core Processor) Remove the four screws that attach the housing cover and remove the cover. The 2400s requires the upper disc to be removed before power or pulse connections can be made to the electronics. Loosen the two Philips screws on the disc and pull disc straight up.
  • Page 8 2. Zeroing the meter Before performing the zeroing procedure: 1. Power the meter for at least 30 minutes to warm up the electronics. 2. Circulate product thru the meter for 5 – 10 minutes to remove vapor and allow meter to reach a steady tempera- ture.
  • Page 9 2.2 Pulse Output Units (continued) Using ProLink 3: To communicate with the unit via the ProLink 3 configuration program, connect the RS-485 adapter to the A & B ter- minals of the service port (labeled SP). Then follow the instructions for “Using Prolink 3” in Section 2, Modbus Units.

    3. SYSTEM COMPONENTS 3.1. RML2000 Coriolis Mass Flowmeter The Coriolis meter is mounted in a similar position to a traditional volumetric meter at the rear of the truck. The meter is connected in line via 2” 300 lb pressure rated flanges to the vapor release and differential valve.

  • Page 17: Display

    3.3. Display The 2x20 character LCD display is primarily intended to show the volume of product being delivered. The two-line display configuration also allows two parameters to be shown simultaneously, such as delivered volume and price during delivery or net and gross volume during calibration. The display is also the method by which the E4000 communicates instructions to operators as they navigate through the software menus.

  • Page 18: Valve Control

    3.6. Valve control Red Seal provides an optional single stage solenoid valve (figure 3-4) to control the opening and closing of the differential valve on LPG meters. The valve is opened only when the E4000 is powered and the start button has been pressed to commence a delivery. The valve will close whenever the stop button is pressed during a delivery or power is lost to the register.

  • Page 19: Printer

    3.7. Printer The E4000 printer is an Epson TM-U295 single feed style dot- matrix printer which uses a standard 4-1/8” wide truck meter delivery ticket , Neptune or Veeder Root. The printer is intended for internal use only and should be mounted in the cab of the truck.

    4. INSTALLATION 4.1. Introduction Before attempting to install an RML2000/E4000 system, read this manual! To simplify installation and reduce the time required, follow the directions provided in this document. Each installation will vary depending on the layout and overall condition of the truck, the fluid being measured, and the installer’s experience with electronic registers and flowmeters.

    The meter may be mounted for either left or right handed flow; however, the flow of liquid through the meter must always be in the direction indicated by the arrow on the meter housing. (Left to right flow when the unit is viewed with the nameplate on the right.) Isolate the meter with valves upstream, downstream, and in the vapor return line, as close to the meter as practicable.

  • Page 22: Installing The Rtd

    4.7 Installing the RTD E4000 registers equipped with an RTD (figure 4-5) are supplied with a ½” NPT male threaded thermowell. The RTD can be installed in the available dual-port strainer cover (figure 4-6). To ensure good conductivity to the RTD, fill the thermowell with anti-freeze or mineral oil before inserting the probe. Note: If replacing the strainer cover, this is a good time to check the strainer and clean if necessary.

    4.9 Installing the Single Stage LPG Solenoid Valve Mount the solenoid valve to the E4000 mounting plate using the bracket provided. Mount the valve with the ports configured as shown in figure 4-8. Connect the COM port of the solenoid valve to the top of the differential valve.

  • Page 24: Wiring The Dual Stage Lpg Valve

    Connect the white wire to terminal 23 and the black wire to terminal 24 on the register’s POWER 12 VDC terminal strip (figure 4-13). Connect the orange wire to terminal 18 (PRESET), and the blue/black wire from the twisted pair to either black wire from the solenoid valve (there is no required polarity for the solenoid valve) and secured with the supplied wire nut.

    4.15 Wiring the RML2000 Meter to the E4000 Register Caution: The RML2000 transmitter electronics are susceptible to damage from electro- static discharge. Make sure you are grounded to the truck frame before making the fol- lowing connections. Using the RML2000 cable kit, insert the leads from the 4-conductor power/encoder cable into the RML2000 transmitter housing and connect to the terminals as follows: Red wire: Positive terminal (+)

    4.16 Installing the Printer The Epson TM-U295 printer is available with the E4000. Find a suitable location in the cab for the printer. End user requirements may vary but a commercially available stand is recommended to secure the printer. Bolt the printer stand to a sturdy section of the cab floor and attach the printer with Velcro strips (figure 4-21).
