5.16.16 DR 23 - Step control through digital input 1, 2, 3, 4, 5, 6, 7

Instead of definable command codes for the digital inputs, step-on conditions can
be controlled by the inputs for scale control (in DR 7, designation 0xFF is defined
with the definition of the digital inputs, see
The following applies for digital input DI1:
0: Weighing waits at step 0 if DI1 is active;
1: Weighing waits at step 1 if DI1 is active
2: Weighing waits at step 2 if DI1 is active
...
7: Weighing waits at step 7 if DI1 is active
The digital inputs 2 to 7 are defined similar to this.
5.16.17 DR 23 - Monitor time step control
This definition enables the monitoring of the duration of a process step:
-
-
If no further stepping to the next process step is performed within the defined time
then the "Step-on Timeout" technology error is generated.
5.16.18 DR 23 - Definition check stop points
A check stop can be effective at the end of a step. This parameter can be used to
define the check stop points. After activating the command "Check stop" (see
command 107), SIWAREX FTA stops at the next point of the process. With the
"Continue" command (see command 103), the automatic processing can continue.
5.16.19 DR 23 - Automatic post dosing
After switching off the fine signal, the SIWAREX FTA waits for the stand-still. Next
is the tolerance check. This parameter is for defining whether dosing should be
done automatically if the weight is less than the set value minus the lower
tolerance TU1:
0: No automatic post dosing
1: Automatic post dosing when below TU1 deviation
5.16.20 DR 23 - Post dosing type
The type of automatic post dosing is defined with this parameter:
0: post dosing with continuous fine signal
1: post dosing pulse mode
