Nudge = simultaneous activation of the CLOSE and Nudge commands (effective only in the
closing direction).
Please see chapter Control unit (Page 35) for the permissible voltage values of an external
power supply.
Note
The X202 24 V voltage output mus
t not be connected to an external voltage potential, for
example a higher-level elevator controller.
The X202 connector 2 (minus 24 V) can be connected to the PE.
