Setting of Parameters:
In case of delivery for control-unit and magnetic chuck together, all settings are optimized.
The controller can be adapted to individual requirements of use. With luffing-switch ”function”,
the menu can be chosen. The different parameters are selectable by the luffing-switch
”value”. After passing the menu, a system-test will be done and the values are memorized.
The presetting of chuck type is done before delivery according to the type label. In case of
a need to change the type of magnetic chuck, it can be done as followed:
a) Switch off mains voltage
b) Disconnect magnetic chuck
c) If a change of mains voltage is needed the internal jumper behind the terminals for
the mains voltage has to be set to 230V or 400V respectively
d) Direct press both buttons , - , simultaneously during switching on mains voltage until
the message “Systemtest” appears
e) Press both buttons, +, simultaneously until the message “Einstellung Magnetart”
(selection magnet type) appears.
f) Scroll to required setting by using the “Value” buttons , + and –
g) Press “Function” buttons, + or -, to leave the menu until system test is done automatically
and the message “Fehler Magnet” (magnet failure) appears
h) Switch off mains voltage
i) Connect the chuck cables
j) Display shows “Systems OK” and is ready to work
