A(all
Minimum weight automatic calibration
– This
parameter defines the value to be displayed when the
minimum reference weight is applied. See the section
Performing Auto Calibration.
A(alk
Maximum weight automatic calibration
–
This
parameter defines the value to be displayed when the
maximum reference weight is applied. See the section
Performing Auto Calibration.
Table 5
shows the sequence of levels and parameters presented in the indicator display. There are parameters that must be defined for each alarm
available.

PROBLEMS WITH THE INDICATOR
Connection errors or improper configuration will result in
malfunctioning of the indicator. A final review can avoid wasting time
and losses.
The indicator some error messages will help the user identify
possible problems.
MESSAGE
PROBLEM DESCRIPTION
VVVVV
Measured value is above the value allowed for the
selected sensor or signal limit.
nnnnn
Measured value is below the value allowed for the
selected sensor or signal limit.
-----
Open input. No signal.
Other error messages shown by the indicator must be reported to the
manufacturer. Inform the serial number if this should occur. The serial
number can be viewed at the display by pressing the
key for
about 3 seconds.
The software version of the instrument can be viewed at the time the
unit is powered.
When not properly configured, the instrument may show false error
messages, particularly those related to the type of input selected.
SPECIAL RECOMMENDATIONS
Should the indicator be repaired, some special handling care should
be taken. The device must be withdrawn from the case and
immediately placed in an anti-static wrap; protected from excessive
heat and humidity.
INPUT CALIBRATION
An appropriate framework should be available for calibration of
equipment capable of providing the electrical signals needed with the
required accuracy.
When recalibration of some type of input is required, proceed as
described below.
a)
Set the indicator for the input type to be calibrated, see
Table 1
;
b)
Program the desired upper and lower display limits (
in.lol
and
in.kil
) with limits on the type of configured input, see
Table 1
;
c)
Access the parameter “
inLo(
” and applied to input a signal
corresponding to a known value and slightly above of the lower
limit.
d)
Set the indicated value using the keys
and
to adjust
the expected value for the applied signal.
e)
Access the parameter “
inki(
” and applied to input a signal
corresponding to a known value and slightly below of the upper
limit.
f)
Set the indicated value using the keys
and
to adjust
the expected value for the applied signal.
g)
Exit the calibration cycle and verify that the calibration became
adequate. Repeat c to f until no new adjustment is necessary.
AUTOMATIC CALIBRATION
To perform automatic calibration, the system must already be
installed and configured with the input type and range already
defined.
a)
Access the Auto Calibration cycle and the parameter
A(all”
.
b)
Put on the load cell the minimum reference weight and wait to
stabilize.
c)
Adjust the parameter
A(all”
to display the desired value.
d)
Press the
P
button to save this value and advance to the
parameter
A(alk
.
e)
Put on the load cell the maximum reference weight and wait to
stabilize.
f)
Adjust the parameter
A(alk
to display the desired value.
g)
Press
P
to save this value and terminate the procedure. At this
time the indicator will show the weight on the load cell.
