NO PRICE ENTRY
While trying to START a delivery, in the Currency Mode prior to selecting a price, the EMR³ 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
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 (>1250 rpm)
will also cause an E04 error.
E06 - TEMP PROBE TOO HOT
The measured temperature is greater than +160°F (71.1°C). 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
The measured temperature is less than -55°F (-48.3°C).
When the fluid temperature is outside of the EMR³ 's measurable range, a delivery can not continue or start. Go
into the C&C Menu, under TEMPERATURE, check what the EMR³ reads for the fluid's temperature. If the EMR³
temperature is wrong remove or replace the thermoprobe and recalibrate.
E08 - TEMPERATURE PROBE FAILURE
The thermoprobe wires are either shorted together or 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 resistance. At 77°F (25°C), the meter should read about 10 K ohms. If not, replace the probe
(Veeder-Root P/N 846000-002).
Startup Error Codes
The following messages apply to self-testing during the power up sequence. Should any of these messages
appear, try cycling the power before replacing the Display Head Module.
E05 - NVRAM FAIL
Test of nonvolatile random access memory. The NVRAM is a piece of semiconductor memory hardware used as a
data storage device. To either write or read data into NVRAM the CPU (central processing unit) places address
and data information on the bus lines and then toggles the appropriate control signals. The EMR
3
uses NVRAM to
store setup values, the current amount of product dispensed and other historical data. Each value stored in
NVRAM has a checksum that validates the integrity for each piece of data. This error occurs when data being read
does not agree with its respective checksum.
