If you are using actuators for safety-related functions, it is essential that you note the follow-

ing:

} A safety assessment must be made for each individual application.

} Input modules may not be used within an output block. If an error occurs, input modules

could supply an external voltage which cannot be switched off.

} The position of each single actuator must be monitored, e.g. via an FS feedback loop

with test pulses.

} To prevent contact welding, a fuse should be connected before the periphery supply in-

feed (see Technical details).

} The following applies for floating actuators:

All actuator masses must be fed back to the output modules.

} The following applies for earthed actuators:

The possibility of a short circuit to + 24 V of the external supply voltage must be exclud-

ed.

When using modules of type PSSu E PD in an output block, please note the following:

} Do not connect capacitive loads.

} During the power-up test, the relay contacts are tested with pulses of up to 60 ms.
