Operation Modes
MAN mode (yellow)
The MAN mode is not actively monitoring the process. However, the unit registers and displays the force
signals to help the operator set up the machine. The MAN mode is normally selected after each STOP to
release the stop relays. In this case , the system will learn new envelope limits after it enters AUTO mode.
The time spent in MAN mode can be limited to an adjustable number of strokes after which the unit will
switch into AUTO mode by itself (adjustment is done within the set-up menu). If wanted, the system can
be set so that it re-uses the previous envelopes without relearning. In this case, after a stop condition, the
system should go directly into AUTO mode.
AUTO1 mode (green)
The green mode starts the automatic monitoring mode. The unit is immediately active after the green
mode commenced. The system either starts learning fresh limits or returns to the previous envelopes (de-
pending on the mode change). In the second case, the unit will wait for a few machine strokes before it re-
sumes the previous envelopes to allow the machine to reach consistant speed.The monitoring limits
(force and acoustic envelopes) are dynamically updated and matched with the process variation. Count-
ing of good parts made starts also. Every impermissible deviation of the process curve signal will cause
the unit to react.
AUTO2 mode
Automatic mode offers the same functions as in AUTO1, but is used when running unmanned shifts. In
addition, the AUTO2 parts counter provides a separate count for parts made during AUTO2 mode. When
stopping the machine during AUTO2, the unit fires the separate EMERGENCY-STOP relay that switches off
the machine entirely (AUTO1 mode will only fire the MOTOR-STOP relay).
STOP (red)
The STOP light comes on every time the unit has switched off the machine. In addition, a machine stop
can be initiated by pushing the STOP key manually. The unit always will prompt a stop
message on the display to identify the reason for switching the machine off.
Selecting operation modes
The different operation modes are selected via the mode buttons when touching the coloured display
beam on the top of any screen. They include functions such as set-up mode or automatic mode for regu-
lar or unmanned shifts. The colour of each display beam indicate which mode is currently running.
