parameters. The BMV-501 can also be fully programmed via this link,
while the complete Function setup can be saved to disk. Furthermore
historic data can be readout, the BMV-501 can be tested and the super-
lock can be (de-)activated.
4.3 Super-lock
With the super-lock feature, the setup menu of the BMV-501 can be
completely locked and secured by a password. In super-lock mode the
historic data cannot be erased either. The normal operating mode is not
affected by the super-lock and the Functions in the setup menu can be
reviewed, but not altered. Only the user/installer knowing the password,
can unlock the BMV-501 via the PC-link.
The super-lock must not be confused with the setup-lock (Function F20).
The big difference between the two is that the setup-lock can be disabled
by anybody, even without communication between BMV-501 and PC.
The setup-lock is used to avoid accidental alteration of the Function
values. The super-lock, however, can only be (de-)activated via the PC-
link using a unique password. The super-lock feature is primarily meant
for warranty purposes.
5. TROUBLESHOOTING GUIDE
PROBLEM REMEDY OR SUGGESTION
The monitor doesn’t operate (no
display) - Check monitor- and battery
connections.
- Make sure the inline fuses are
installed and not blown.

might be flat.
Vbatt must be
> 8VDC.
- Try to restart the monitor by
removing/placing the fuses
again.
Current readout gives wrong
polarity (positive current instead
of negative when discharging) - Current sense leads from the
shunt are reversed. Check the
installation guide.
The monitor resets all the time - Check the wiring for corrosion
and/or loose contacts.
