4.5 Measured value display
The measured value can be read at V0H0. In addition to this, several other fields contain
system information which might be needed, e.g., for trouble-shooting etc.. Table 4.3
summarises the displays.
4.6 Parameter locking
When all parameter entries have been made, the matrix can be locked by entering any
code number less that 670 or greater than 679 in V8H9.
Step Matrix Entry Remarks
1 V8H9 e.g. 888 Enter any code from 000 - 669 or from 680 - 999
2 - »E« Register entry
After locking, all entries can be displayed but not changed.
•
The lock is released when a number between 670 and 679 is entered at V8H9.
Note your parameters! The instrument is now configured. Note your parameters in the table at the back of the
manual - if you have to replace the transmitter, these can be simply entered in the
replacement Prolevel FMC 661. For level probes on channel 1 there is no need to
recalibrate.
Channel 1 Measured value Remarks
V0H0 Level or volume Display in %, m, ft, hl, m
3
, ft
3
, t etc. according to
calibration and/or linearisation.
The entries for the 0/4 mA and 20 mA value at V0H5
and V0H6 control the 10-step LCD bar diagram.
V0H8 Current measuring
frequency channel 1 Displays the frequency which is actually measured
by the probe. Can be used as a fault check (must
change as level changes)
V0H9 Measured value before
linearisation Indicates level before linearisation in the units used
for calibration
V8H7 Factor for calibration
correction For operating mode 5, displays correction factor
used in calibration.
Can also be used to enter a density factor when
used with a Deltapilot S
V8H8 Current measuring
frequency channel 2 Displays measuring frequency for Channel 2 when
operating modes 0, 2 and 5 are selected.
V9H0 Current error code Error code of fault with highest priority appears on
fault condition, alarm LED lights or blinks
V9H1 Last error code The previous error can be read and deleted here -
press »E« to delete
V9H3 Software version with
instrument code The first two figures indicate the instrument, the last,
the software version; 33 = Version 3.3
V9H4 Rackbus address Indicates RS-485 address set at DIP-switches
