EMR4 Troubleshooting Guide Delivery Error Codes
64
NEW CALIBRATION REQUIRED
After assigning a Product Type or a Cal Number to any Product Description number, this message alerts the user
to recalibrate the meter in the Meter Calibration Setup. If the user does not recalibrate the meter, the EMR4 will
use an incorrect meter calibration factor to calculate volume.
NO RECORDS
Inside the Display Head there are zero transactions stored. This message appears in the Setup Mode, when the
user attempts to print or view transaction records on a new start-up, or after clearing NVRAM by using the
RESTART feature in C&C mode. This message does not apply to the transaction records stored in the IB and IB
records can be restored back to the Display Head.
RECALCULATING
While in the C&C Mode this message is displayed during the meter calibration procedure when new calibration
points are calculated. Each point takes a few seconds to calculate.
NO PRICE ENTRY
While trying to START a delivery, in the Currency Mode prior to selecting a price, the EMR4 will display this
message. Once the desired price is on the preset display, use the ENTER button to select it.
SELECT PRODUCT
When more than one product is available, the user must choose one product prior to each delivery. Press +/-
button to display the desired product then press ENTER to select it.
Delivery Error Codes
Notice: The current delivery will automatically FINISH when a delivery error occurs.
E04 - ENCODER PULSE ERROR
This error is an indication that an illegal quadrature state has occurred. It is possible this error is caused by a
random event and another delivery may be started. Should this error repeat itself, the source of the error must be
fixed. Before replacing the encoder check the IB input voltage for dropout or power surges. Some solenoid valves
do not have diode suppression and may cause the supply voltage to drop out. Add diodes (Veeder-Root P/N
846000-022) across the solenoid coils as noted in the installation manual. An over speed condition (>2500 rpm)
will also cause an E04 error.
E06 - TEMP PROBE TOO HOT
The measured temperature is greater than +160°F (71.1°C) or the thermoprobe wires are shorted together. This
error can also be caused by poor connections in a junction box when wire is added to the original temperature
probe and a poor connection is made. Soldering is recommenced - not just wire nuts.
E07 - TEMP PROBE TOO COLD
When the fluid temperature is outside of the EMR4's measurable range, a delivery can not continue or start. Go
into the C&C Menu, under TEMPERATURE, check what the EMR4 reads for the fluid's temperature. If the EMR4
temperature is wrong remove or replace the thermoprobe and recalibrate.
E08 - TEMPERATURE PROBE FAILURE
1. The thermoprobe wires are not connected to the TP terminals on the Display Head. Check the thermoprobe
connections on the back of the Display Head. If the thermoprobe wiring is corroded, remove both leads and
trim them. Cut back the cable insulation and strip each wire by 1/4 of an inch (5 mm). Insert both wires into the
terminal block and tighten. To test a thermoprobe, connect each lead to an ohmmeter and measure the resis
-
tance. At 77°F (25°C), the meter should read about 10 K ohms. If not, replace the probe (Veeder-Root P/N
846000-002).
2. The measured temperature is less than -55°F (-48.3°C).
