This results in a unique state that must be achieved after the machine has
been switched on and no permissive button is pressed. At the handwheel
adapter (ID 296466-xx) this state is X1/1 = 0, X1/2 = 0 for standard
handwheels and X1/1 = 0, X1/2 = 1 for FS handwheels. The same state must
also be achieved if the corresponding dummy plug is used. The PLC program
should check this unique state when the machine is switched on, to make
sure that the correct handwheel or dummy plug for the respective machine
configuration is connected. If the expected state is not achieved, an error
message is to be triggered and the machine operator is to be prompted to
attach the correct handwheel or dummy plug. Using an incorrect handwheel
or dummy plug leads to a PLC input (one channel) always carrying the
information that a permissive button is pressed.

Only qualified personnel may connect and exchange handwheels and
dummy plugs.
It is essential that operative actions (such as pressing the emergency
stop) on handwheels that are not connected are not possible.
Handwheels and dummy plugs that are not connected to the machine,
and are therefore without function, must be removed from the machine.
Handwheels and dummy plugs that are not being used must clearly be
stored away from the machine, such as in a locked cabinet.
Only FS handwheels and dummy plugs for FS handwheels (ID 271958-05)
may be used on systems that are prepared for FS handwheels.
Only standard handwheels and dummy plugs for standard handwheels
(ID 271958-03) may be used on systems that are prepared for standard
handwheels (without FS).
