AUMA Aumatic ACExC 01.1 User Manual

The EMERGENCY function is defined via the parameters for the operation
mode EMERGENCY. Refer to the operation instructions to the actuator
(multi-turn actuator SA(R) … / part-turn actuator SG . . . with AUMATIC AC . . .).
If the actuator is to be operated via fieldbus or the inputs of the I/O, the selector
switch has to be in position “REMOTE”.
As soon as the EMERGENCY signal is no longer present (EMERGENCY input
at 24 V DC or 115 V AC as an option), operation commands which are trans-
ferred via DeviceNet are immediately executed, while OPEN/CLOSE operation
commands which are present at the additional control inputs are deleted and
have to be reapplied.
Note:
An automatic change-over to the I/O in case of an interruption of the bus
communication does not exist!
