Function
Automatic mode
The keys on the keypad have no function. The LEDs on
the "QUICK STOP DISABLE", "RIGHT", and "LEFT" keys,
however, are active. They are used for indicating the status
(= status of control via the PIO).
Manual mode
Control priority is assumed by a lower-priority control
source (automatic mode) and transferred to the keypad.
When you switch back to "REMOTE", control priority is
always initially passed to the CPU/master.

OFF / Reset
When you switch to this position, a fault that is present can
be acknowledged with trip reset (provided that it can be
reset). If the key-operated switch remains in this position,
the motor starter is in the "O" position once the "Reset"
command has been issued. The motor starter does not
execute any control commands in this position (regardless
of the control source).
Note
The key can be inserted/removed in any position.
