You can decide to connect the teach-in key-operated switch to the C 4000 or to the
UE 402. If you connect the teach-in key-operated switch to the UE 402, you cannot connect
a key-operated pushbutton for bypass, and the bypass function can therefore no longer be
used.

For PSDI mode, the machine cycle contact of the machine must be connected to the
UE 402. Depending on the PSDI mode, the UE 402 can evaluate various contacts, some
are mandatory (Tab. 6).
The signals of the machine cycle contact MCC-BDC and MCC-TDC are allowed to briefly
overlap each other. MCC-BDC must always fall away before MCC-TDC.
