EMR4 Truck Installation Installing The Interconnection Box (IB)

NOTICE

EMR3 - Truck Installations

Installing The Interconnection Box (IB)

The IB box is not rated for mounting in outdoor locations. The IB box can be mounted only
in a protected enclosure or protected location.

The following information is for general reference and is not intended to replace recommended National Electric
Code (NEC) 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 other applicable code requirements.

1. The physical dimensions of the Interconnection Box (IB) are shown in Figure 2.The IB is installed in the truck’s
cab either under the seat, mounted on the wall inside the cab, mounted to the passenger si

Input Power – Critical Ground Connection

On some vehicles, the battery minus terminal, BAT(-), may not be common with the chassis ground or the defined
vehicle ground located in either the accessory panel or in the power distribution box. In this case, directly run the
ground connection for Input Power at J8, Pin 2 (GND) terminal as shown in Figure 3, directly to the BAT(-) terminal
connection point.

Proper operation of the EMR4 hardware depends on the quality of the ground connection from the Interconnect
Box to the source of INPUT-PWR power.

If the INPUT-PWR connection is made at the accessory panel, it must be fused at 5 amps. The installer must
ensure that a minimum of 12.0 volts, between the INPUT-PWR terminal and the GND terminal, is available from
the power source. If an improper ground point is used for input power to the EMR4 there may be insufficient
power for the Display Head to operate properly resulting in various E## error codes or possibly a blank display.

Pay careful attention to the wiring labels on both the EMR4 Display Head and the Interconnect Box.
Each connection must be made according to the wiring tables listed in this manual. Use shielded
cable to connect each device to the Interconnect Box and Display Head and ensure that each cable
jacket is resistant to gas and oil.

EMR4 Truck Installation Input Power – Critical Ground Connection

NOTICE

NOTICE

EMR3 - Truck Installations

Installations With High Amperage Devices

The input power for an EMR4 must be isolated from devices that use large amounts of electric current such as reel
motors. Connect the EMR4 using dedicated wiring between the voltage source and the Interconnect Box. On
vehicles with multiple voltage sources it may be necessary to use a separate battery or voltage source to power
the EMR4. Also, a battery isolator can be used between the voltage source and the IB to prevent voltage spikes
from entering the Interconnect Box when the high amperage devices are de-energized.

Recharging Vehicle Batteries

In the Interconnect Box, disconnect the wires for both the INPUT-PWR and GND Terminals while charging the
vehicle’s battery. Failure to do so can result in hardware damage to the circuit board inside the Interconnect Box.

VALVE OPERATION WITH THE EMR4

Full Flow

The valve is normally closed. When the START button is pushed on the EMR4 display, both relays for that head are
energized, opening the solenoid-operated valves. The Fast Flow solenoid valve allows the main valve diaphragm to
open via the pump pressure pushing on the diaphragm. Full flow is obtained. The Slow Flow solenoid valve allows
flow around the main diaphragm valve. When the FINISH button is pushed on the EMR4 display, both relays are
de-energized, the solenoid valves close stopping flow.

Preset

The valve is normally closed. When the START button is pushed on the EMR4 display, both relays for that head are
energized, opening the solenoid valves and fast/full flow is obtained.

• First Stage Knockoff - When the first stage/slow flow point is reached (1st stage knockoff), the fast flow/relay
de-en

ergizes and the spring assisted main diaphragm of the valve closes as the pressure equalizes. The si

3-Way Safety Valve For Truck LP Gas Systems

The 3-Way Safety Valve is not intended for flow control or preset control.

WARNING

The Three-Way Safety Valve is installed and operated in the highly
combustible environment of an LPG tank.

FAILURE TO COMPLY WITH THE FOLLOWING WARNINGS AND SAFETY
PRECAUTIONS COULD CAUSE DAMAGE TO PROPERTY, ENVIRONMENT,
RESULTING IN SERIOUS INJURY OR DEATH.

1. It is essential that you carefully read and follow the warnings and
instructions in this manual to protect yourself and others from serious
injury due to fire, explosion, or electrical shock. LPG systems shall be
installed in accordance with the national standards and regulations that
apply.

2. Comply with all federal, state, and local codes, and other applicable
safety codes. All wiring must comply with standard electrical practices,
the local authority, and the latest editions of the National Electrical Code
(NFPA 70) and other applicable code requirements. All work on LPG
systems must comply with NFPA 58, Liquefied Petroleum Gas Code and
other applicable code requirements.

3. LPG tanks must be depressurized (drained) and free of liquid and
combustible vapors before work begins.

4. Flow control valves connected to the EMR4 must be UL Listed. Also, flow
control valves must be suitable for the intended application, i.e.,
gasoline, fuel oil, LPG and must be rated for use in a Class 1, Division 1,
Group C or Group D Hazardous Location. For LPG applications, such as
propane, each valve must have a minimum pressure rating of 350 psi.

INSTALLING THE 3-WAY VALVE

On the male pipe threads, use a pipe sealant when installing fittings or conduit to either
the valve or the junction box.

1. On the valve, install a rigid metal conduit nipple in the threaded opening, provided for the solenoid wiring. Run
the two red wires from the 3-way valve, through the nipple and into a metal junction box. Mechanically attach
the valve/nipple combination to junction box as shown in Figure 5. Even though the 3-way valve will operate
in any position, it will last longer and perform best if mounted vertically upright (port 3 up). Secure the
junction box to the vehicle's frame.

2. Run a 2-wire shielded cable from the Relay Terminals located at J7 in the IB Box, located in the truck cab, to
the 3-way valve junction box. Pass the cable through a cord grip fitting in one of the J-box openings. Cut off 1­inch (25.4 mm) of the cable’s shield and jacket, then strip off 1/2-inch (12.7 mm) of each wire’s insulation.

NATIONAL ELECTRICAL CODE COMPLIANCE

The following information is for general reference and is not intended to replace recommended National Electric
Code (NEC) 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).

GROUNDING

Proper grounding of the EMR equipment is essential for several reasons. First, in a typical installation, grounding
prevents hazardous voltages from being present on the equipment. Secondly, grounding prevents the build-up of
static charge on the equipment. Either of these conditions could be very hazardous when in the proximity of
explosive mixtures found at fuel supply depots and terminals. Proper grounding requires that a very low impedance
connection be made to the earth. At the distribution panel, this is accomplished by means of a dedicated
conductor buried in the earth. It is imperative that all local, regional and national regulations are followed when
connecting to the grounding system.

WIRE TYPE FOR METALLIC OR PVC CONDUIT

Veeder-Root requires the use of shielded cable when using metallic or PVC conduit in any portion of the wiring
between the Display Head and the IB. In these installations, shielded cable must be rated less than 100 picofarad
per foot and 0.2 microhenry per foot (per 304.8 mm) and be manufactured with a material suitable for the
environment.

Use either the 4-wire cable supplied by V-R, P/N 846000-1XX or any equivalent cable or wiring with rated
capacitance of less than 100 picofarads per foot (per 304.8 mm) and inductance of less than 0.2 microhenry per
foot (per 304.8mm). Note that conductor wire colors vary depending on the cable manufacturer (caution: the
Display Head to IB wiring illustrations in this section show wire colors in the V-R cable. Alternate cables may have
different wire colors).

Field wiring may be both above ground or below grade.

WIRE LENGTH

Improper system operation could result in undetected potential environmental and health hazards if the Display
Head to IB wire runs exceed 1000 feet (304.8 m). Wire runs must be less than 1000 feet to be within the limits of
the UL Certification.

MOUNTING AND WIRING THE IB UNIT

1. The physical dimensions of the Interconnect Box (IB) are shown in Figure 2 on page 6. The IB is installed in

PULSE OUTPUT LIMITS

EMR4 Setting Maximum Fueling Rate

0.1 pulse/gallon 450,000 gpm

1.0 pulse/gallon 45,000 gpm

10 pulses/gallon 4,500 gpm

100 pulses/gallon 450 gpm

1,000 pulses/gallon 45 gpm

Limits are dependent on the time it takes the EMR4 to send pulses. In this example, a gallon is used to represent a
unit of volume and gpm is gallons-per-minute.

The EMR4 has a maximum pulse rate of 750 pulses per second or 45,000 pulses per minute. At high fueling rates,
the EMR4 will need extra time to send out all of the required pulses. Use the following examples as a guide to
setting the correct pulse-to-unit-volume ratio on the EMR4. Reference the EMR4 Setup And Operation Manual,
577014-350, to enter a value under the SET PULSES/VOL menu.

Example of a correct setting:

Set the PULSES/VOL value to 10 pulses per gallon and deliver 1,600 gallons at a fueling rate of 800 gpm. The
actual delivery takes 2 minutes and the EMR4 can transmit 16,000 pulses within the 2 minute time frame.

Example of an incorrect setting:

Set the PULSES/VOL value to 100 pulses per gallon. Deliver 3,200 gallons at a fueling rate of 800 gpm. The
actual delivery takes 4 minutes while the EMR4 takes (320,000 pulses/45,000 pulses per minute) 7 minutes to
process the delivery data. It takes the EMR4 three additional minutes to transmit the last 140,000 pulses!
Consider both the flow rate and the time it takes to send all of the pulses prior to setting the PULSES/VOL value.

The EMR4 system does not provide volume pulses in real time. There is an unspecified
delay in the time it takes the IB to process volume data provided by the display head.
