9 Optimization
9.7 Basic adjustment, mode range
optimization
All parameters, their data modified during an optimization
can be reset to factory setting if necessary.
Programming example
• Enquire mode 1 - 27 in the MODEFIELD
• Modify figure 0 to figure 1 in the PARAMETER FIELD
• Then activate the basic adjustment with key STO
Influences
- CAL (flashing) appears for approx. 3 secs. on the
display.
- All modes of the optimization are reset to factory setting
(see protocol)
- The measuring system starts a new feeding phase,
therefore the fail safe relay de-energizes and the failure
LED lights.
- CAL extinguishes after 3 secs. and the figures 0.000
remain displayed.
- This means, basic adjustment activated, feeding phase
started.
- After approx. 1 … 3 mins. the operating status is
reached again. The fault signal extinguishes and the
measuring system operates with the parameters of the
factory setting.

9.6 Fault signal
The fault signal is triggered when the measuring reliability
is not ensured. The measuring reliability is calculated out
of the ratio echo measurement to noise level
measurement.
The fault signal can be varied as follows:
Explanation in case of fault
Fault signal of mode 1 - 24 = 0 (factory setting)
- Indication of the error code on the display.
- The last as correct detected measured value is stored.
- With the detection of a new correct echo, the last stored
value is cancelled and the actual value is indicated.
Fault signal ON mode
1 - 24
=
1
- Indication of the error code on the display.
- The fail safe relay de-energizes.
- The signal LED lights.
- With the detection of a new correct echo, the fleeding
phase is automatically started and after it is finished an
actual measured value is given.
In both cases the relay and current outputs react acc. to
the failure processing given in mode
0 - 93 .
Programming example
• Enquire mode
1 - 24 in the MODEFIELD
• Program fault signal ON with 1 in the PARAMETER
FIELD
• Then store with STO
