7.6.3 AIS
Prerequisite
: AIS system
The AIS (Adaptive Injection System) automatically regulates the dosing valve stroke.
A stepping motor increases or decreases the stroke in steps.
AIS settings
(password level 4)
Parameter Explanation
Unit
Values
Default
G300
Number of dosing valve cycles after the AIS has performed
a calculation.
Note:
When starting the mixing mode, the AIS must wait
for these cycles, before the adjustment can begin.
Cycles
3–100
3
G301
Warning limit: Minimum injection quality (opening time of
the dosing valve in percent). If the value falls below this, a
warning is triggered (code 97).
%
0–100
10
G302
Lower injection quality limit (opening time of dosing valve as
a percentage). If the value falls below this, the AIS optimizes
the injection quality.
%
0–100
50
G303
Upper injection quality limit (opening time of dosing valve
as a percentage). If the value falls below this, the AIS limits
the injection quality. Thereby smooth operation is ensured.
%
0–100
60
G304
If the dosing valve is continuously opened for longer than
the stated time, then too little product flows through.
The AIS allows more product through.
sec
0.5–25.0
1.5
G305
Repetition interval: For the above function (P304), the AIS
undertakes a step every x seconds until the valve cycles
again.
sec
0.5–25.0
1.5
G306
Number of steps which the AIS is to open when mixing
operation is ended.
Steps
0–20
5
G307
Minimum flow of all components for AIS to undertake
regulation.
cc/min
5–1000
100
AIS Information
(view only, password level 4)
Parameter Explanation
G308
Current opening time of the dosing valve in percent (0–100%)
G309
Current AIS position. The start value (after pressing the START push button) is 1000. Each step
of the stepping motor changes the value by 1. A number greater than 1000 increases the flow
rate. A number less than 1000 decreases the flow rate.
