Part 7
Response to mains voltage return:
The response depends on whether bus voltage is available or not when the mains voltage returns.
If bus voltage is available, all outputs are being shut off or remain off (stop) until a new bus telegram is
received and the switching state changes.
Exception: The actuator automatically reactivates the safety function(s) in the outputs assigned, if the
safety objects were activated before or during the mains failure. The parameterized "Response at the
beginning of the safety function" is re-executed. A safety function activated before the mains failure and
deactivated during the failure does not start a new movement on return of mains voltage. If, during mains
failure, a safety function was activated and then deactivated again, the actuator starts a new movement
for the outputs assigned after mains voltage return as parameterized for "End of the safety function". The
outputs concerned are in any case re-enabled after safety deactivation.
If the bus voltage is not present on return of mains voltage, the parameterized "Response on bus voltage
failure" is started ("Stop" is factory-adjusted in unprogrammed actuators).
Manual control is possible again.
Response to bus and mains voltage return:
The parameterized "Response on bus voltage return" is started. Manual control in this case is possible.
(Cf. also "Response on bus voltage return" / "Response on mains voltage return")
Programming procedure:
After the end of programming by the ETS or after a bus reset (bus voltage return), the parameterized
"Response on bus voltage return" is executed. After programming, the manual control mode is terminated.
Manual control depending on bus and mains voltage:
Manual control is only possible when mains voltage is available. Depending on the "Manual control on bus
voltage failure" parameter on the "Manual control" card, manual control with no bus voltage applied is
possible. An activated manual control mode ends on return of bus voltage.
