4.3.4 LEARN mode
HOLD
LEARN When editing a method, the parameters of a command are most easily
determined experimentally, i.e. by manual execution, and it is for this
reason that certain commands are "teachable". The LEARN function
makes the manual execution of particular changer commands possible
during the editing of a sequence. The resulting parameters (for exam-
ple, the lift position or the status of the input lines) can be taken over in
the current command line. The LEARN function can be used repeti-
tively. When times or volumes are "learned", the repetitive values are
added up.
Procedure for creating a method
x Enter a command or select an existing command line.
x Press the key.
Function is started, "LEARN" LED lights up.
Press the key.
Function is stopped, "LEARN" LED blinks.
With the key, accept the value
(or re-start the LEARN function).
x "LEARN" LED goes out, edit next command line.
The LEARN function can be used with the following commands:
Command Teachable parameter Mode of function
LIFT Lift position in mm absolute
PUMP Pump time in sec additive
WAIT Waiting time in sec additive
SCN Rm Status of the 8 remote lines "live" value
SCN RS Character sequence received "live" value
4.3.5 TRACE function
START
The "TRACE" function is a valuable aid for operating through an entire
sequence or method (or parts thereof) for test purposes. Every com-
mand line in a sequence can be executed directly by pressing the
key. Upon completion of the action the next command line
is displayed.
Tracing can be executed immediately after entry of a sequence line or
at any time after opening the parameter menu and selecting a se-
quence.
