) The state "externally voltage detected" appears, if the output of a channel DC0...DC7 should
be switched on while an externally voltage is connected Ä Chapter 1.7.5.2.3 “Connections”
on page 798. In this case the start up is disabled, as long as the externally voltage is con-
nected. The monitoring of this state and the resulting diagnosis message can be disabled by
setting the parameters to "OFF".
