4. Programming routine
The adjustable parameters of the device are explained
in the order of their appearance on the display. There-
fore the device is completely programmed after one
passage of the programming cycle.
The upper display representation shows always the fac-
tory setting.
4.1 Input signal range
0..20 mA
4..20 mA
0..10 V
2 ..10 V
Press the right key to replace the factory setting with
one of the other input signal ranges.
4.2 Decimal point adjustment (current value)
This setting determines the decimal point for the related
display values (4.4 and 4.6). This setting only deter-
mines the number of decimal digits, the display value is
not affected (no scaling).
no decimal place
0.0 one decimal place
0.00 two decimal places
0.000 three decimal places
four decimal places
Press the right key to replace the factory setting with
one of the other possibilities.
4.3 Minimum input signal
Only for the 4..20 mA or 2..10 V measuring ranges (this
menu item is skipped with the other ranges).
This function allows monitoring the sensor. If the meas-
ured value falls below the minimum value defined here,
the message “lo” is displayed. The sensor used is faulty.
The values displayed are not added.
a)
Factory setting
Maximum setting
b)
Factory setting
Maximum setting
According to the selected measuring range (4..20 mA
or 2..10 V), the device asks for programming of a) or b).
With the left key select the decade, then use the right
key to determine the measurement value that is to cor-
respond to the minimum value.
4.4 Value displayed for the minimum input signal
A display value between -19999 and 99999 can be allo-
cated to the lowest input value. When the display val-
ues for the lowest and the highest input signal are
defined, the system displays a display value correspon-
ding to the analogue measurement value, as shown in
Example 9.1 on page 4, with a momentary throughput
in kg/second.
Factory setting
Maximum setting
With the left key select the decade, then use the right
key to determine the value, for example”0". The decimal
point adjustment is taken into consideration.
4.5 Maximum input signal
Only for the 4..20 mA or 2..10 V measuring ranges.
This function allows monitoring the sensor. If the meas-
ured value exceeds the maximum value defined here,
the message “hi” is displayed. The sensor used is faulty.
The values displayed are not added.
a)
Minimum setting
Factory setting
b)
Minimum setting
Factory setting
According to the selected measuring range, the device
asks for programming of a) or b).
4.6 Value displayed for the maximum input signal
Factory setting
