4.9.5.3 LOADER
REVERSING
In case of need it is possible to reverse the loading mechanism. Use reversing in the loading
mechanism motion in non-standard situations (bar jammed), when it is necessary to reverse
the loading mechanism.
How to reverse the loader
•
Use the key
to activate the loader reversing.
•
Now at pressing the key
or
the loading motor will turn in reverse direction as long
as the key is pressed.
•
Cancel the reversing by means of the key
.
•
Press and hold the key
or
until the pusher stops in the lower or upper limit
position.
Loading mechanism reversing should only be used in exceptional cases
(setting, accident ...), when it is necessary to move the loader contrary to
normal motion direction.

MATERIAL SWITCH CALIBRATION (SS2400S)
In the front part of the channel (on the lathe side) of the Barfeeder SS2400S there is a
material switch B34, by means of which the length of bars fed into the lathe is measured. The
barfeeder must know the switch position with regard to the origin of coordinate system. For
this purpose the material switch calibration function is used. The position of the material
switch is stored in the parameter #108.
How to calibrate the material switch
•
Change over to the manual mode and using the key
move the pusher into the upper
limit position.
•
Set the channel in the upper limit position (for diameter 6 mm), and secure it.
•
Select and press the key
, which initiates the switch calibration.
•
The flag goes to the front limit position and returns. In forward motion the barfeeder
measures the material switch position by hitting its diaphragm. Thus the channel must be
in such a position that the flag passage activates the material switch.
•
Return the channel into the original position.
When to calibrate the material switch
The material switch must always be calibrated after any modification/maintenance of the
barfeeder such as replacement or modification of the switch diaphragm which may result in
possible change of the switch position relatively to its reference point.
Do not write in the parameter #108 directly, but always use the material
switch calibration function. Only this function will ensure precise setting of
the parameter #108.
