4.4 Product Data
Enter product data for parameter setup and calibration separately for each product.
Product select
No. 1/2/3/4:
Enter product number for calibration.
Current Output
Select current output signal 0 or 4 mA.
Current Output Limits
0/4 mA:
Enter density or concentration value which is to correspond to 0 or 4 mA in the defined
unit, e.g. in % concentration.
20 mA:
Enter density or concentration value which is to correspond to 0 or 4 mA in the defined
unit, e.g. in % concentration.
Example:
Measuring range 10 ... 30 % concentration.
Input: at 4 mA: 10
at 20 mA: 30
Current Output Error
Current:
VALUE
In case of error, the current output jumps to the defined value ( 0...22 mA)
HOLD In case of error, the current output holds the last value.
Caution: If you have selected “continue in case of error”, the current output
operates using a wrong value corresponding to the false value.
Relay No. 2 setup
Minimum / Maximum / Det. Temp. / Mass pulse:
Different functions can be assigned to the relay. As soon as the status to be signaled
Density / concentration < minimum or
Density / concentration > minimum
Detector temperature > X °C
has been reached, the relay is de-energized. If the displayed value drops again, the relay
picks up again, delayed by the value of the selected hysteresis.
Hysteresis
The switching hysteresis should be about 5%.
Mass Pulse
The relay may also be used to supply pulses to an external counter during mass flow
measurement. The significance / pulse (t) is entered under menu item “Mass flow”.
Relay No. 3 Setup:
Same as relay no. 2. However, there is not input option for a mass pulse.
Minute printout
Value
The integrated mass can be printed out in defined time intervals using a printer con-
nected to the RS 232 interface.
