IND690-Fill
LEARN MODE Switch Learn mode on or off
If LEARN MODE ON is set and the dispensing parameters are entered without limits
or limit 2
≤ limit 1, the IND690-Fill determines the valve switch-off points limit 1 and
limit
2.
If LEARN MODE OFF is set, limit 1and limit 2 must be entered manually.
Factory setting: LEARN MODE ON
• The coarse feed is opened (1) in the learn mode up to the value (target value x
trip factor coarse feed) and the redispensing correction determined (2). Then the
fine feed is opened (3) during the number of measuring cycles specified with the
trip factor fine feed and its redispensing correction determined (4). Then limit 1
and limit 2 are calculated in dependence on the target value. Following this filling
is carried out up to the target value (5), (6) and (7).
TRIP FACTOR COARSE The trip factor coarse feed determines when the coarse feed is switched off in the
learn mode.
• Possible values: 0.1 … 0.9 (factory setting: 0.5).
• With high pressures and pulse forces or large mass feeds, reduce the trip factor.
TRIP FACTOR FINE The trip factor fine feed specifies how long the fine feed is open in the learn mode.
The larger the trip factor fine feed, the more accurately the fine feed run-on can be
determined.
Possible settings:
TRIP FACTOR FINE FEED = 0.1 ... 0.9 (Factory setting: 0.5)
The value 0.1 is equal to 5 measuring cycles, 0.5 is equal to 25 measuring cycles
and 0.9 is equal to 45 measuring cycles.
Comments • If SINGLE FEED OPERATION ON is set, limit 1 is set to zero in the learn mode.
• TRIP FACTOR COARSE and TRIP FACTOR FINE are available as application blocks
(blocks 363 to 367).
