    EMR4 Truck Installation Installation of the EMR4 System involves installing the Display Head(s), the Interconnect Box, and any optional devices (e.g., Remote Pulser, printer, etc.). This equipment must be installed according to the applicable installation document. For UL/cUL installations use Control Drawing number 331940-021 and for ATEX installations use Descriptive System Document number 331940-022.

    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.
  • Page 9 Installations With High Amperage Devices NOTICE 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.

  • Page 33: Pulse Output Limits

    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.
