diagnostics and troubleshooting overview
The LCR 600 provides tools for diagnosing and troubleshooting itself as well as other aspects of the flowmeter
system. The three main diagnostic tools are error messages, diagnostic and status screens, and diagnostic tickets.
The LCR 600 will display an error message when the register can not execute a command or can not continue
functioning until the error is corrected or the settings are modified. The diagnostic and status screens provide
a detailed account of the status of the LCR 600. Diagnostic tickets are a summary of calibration data, system
identification information, temperature probe data, error messages, and other useful bits of information.
error messages
The LCR 600 notifies users of entry errors and system errors as soon as they occur. When an error occurs, a
shaded box with a short description of the error will appear on the display. Many error messages include additional
instructions and options. If necessary, the additional options will lead to the diagnostic screens, where the status
of the LCR 600’s status can be investigated. In many cases, printing a diagnostic ticket is helpful in diagnosing the
cause of the error. See page 44.
The following list of LCR 600’s error messages provides an explanation of each error and possible corrective actions.
If the corrective actions are not successful, consult the troubleshooting section. If problem persists after following the
troubleshooting tips, call an authorized Liquid Controls service provider.
fuelIng error meSSageS
These messages may be displayed when the LCR 600 is attempting to start, in the midst of, or finishing a fueling.
Delivery ticket pending
A new fueling was attempted but the previous fueling ticket was not printed in its entirety. Turn the selector switch to
the PRINT position. Once the previous fueling ticket is printed, a new fueling can begin.
Check printer and cable
The printer is not responding. The most common cause is the absence of a ticket in the slip printer. Epson slip printers
have a built in photo eye to detect if a ticket is in position. If there is a ticket in the printer and the “Paper Out” light
is still illuminated, adjust the ticket in the printed until the light is off. Other causes include faulty data cable or power
cable and LCR 600 circuit board failure.
Warning: Data storage full. Continue fueling, save tickets. Notify Manager
The LCR 600 memory is full and no more transactions can be recorded. Typically, this is a sign that communication
with the office is not functioning. The office should be notified and the fueler should save all fueling tickets until
communication is reestablished.
ROM CHECKSUM ERROR
The program memory space of the LCR 600 has been corrupted. If this error occurs, the unit must be reflashed with
the control software before any fuelings can be made. Contact a LC service provider to reflash the LCR 600.
TEMPERATURE ERROR
The temperature circuit returned an error or the temperature calibration data is in error. Check the temperature probe
and its connections. A broken temperature probe wire is the most common cause of this error. See the troubleshooting
section for more information. See page 46.
VCF DOMAIN ERROR
The calculated temperature falls outside the allowable range for the current compensation parameter. Verify that the
product compensation type is correct on the Calibration Setup 2 screen. See page 23.
PULSeR FAILURe
The number of pulser faults exceeds the allowable amount. Pulser faults typically occur in high vibration environments
or when the flow rate is highly throttled. The LCR 600 allows a maximum of five times the number of pulses required
for the least significant displayed digit or 0.1% of the pulses generated for the current fueling. This equation can not
be altered. Liquid Controls is not responsible for pulser failures caused by excessive system vibrations. See the
troubleshooting section for more information. See page 47.
METER CALIB ERROR
The product selected for fueling has not been calibrated. Setup and calibrate the product, or if the product has already
been calibrated, select the calibrated product.
No FLoW SToP eRRoR
The no-flow timer expired and terminated the fueling. This is not an error condition. See General Setup 2 to edit.
