8.5.5
Special case: replacement of central module
Note:
Replacement central module LSCx-x
is supplied from the factory with
instrument serial no. 0000. Since the
serial and release numbers are
linked for the S package and
Chemoclean, an existing S package
or Chemoclean may not be active.
All the editable data are reset to the
factory settings following central
module replacement.
Proceed as described below after central
module replacement:
• If possible, record the user settings of the
instrument, e.g.:
–
Calibration data
–
pH / mV and temperature current
assignments
–
Relay function selections
–
Limit / controller settings
–
Cleaning settings
–
Monitoring functions
–
Interface parameters
• Dismantle the instrument as described in
chpt. 8.4.2 or 8.5.2.
• Refer to the part no. of the central module
to determine whether the new module has
the same part no. as the old one.
• Assemble the instrument with the new
module as described in chapter 8.4.3 or
8.5.3.
• Start up the instrument and test its basic
functions (e.g. meas. value and
temperature display, operation via
keyboard).
• Enter the instrument serial number:
–
Read the instrument serial number
(“ser-no.”) on the nameplate.
–
Enter this number in the fields E114
(year), E115 (month), E116 (sequence
number).
–
Field E117 displays the complete number
for verification; acknowledge with ENTER
or abort and re-enter.
Please note:
The serial number can only
be entered – and
only once
– in the case
of a new module from the factory with
serial number 0000! Make sure that your
entry is correct before confirming with
ENTER! Entry of an incorrect code will
prevent the enhanced functions from being
enabled. An incorrect serial number can
only be corrected at the factory.
• Verify that the S package is enabled (e.g.
by accessing function group CHECK /
Code P) or the Chemoclean function.
• Restore the user settings of the instrument.
