Preconditions
A safe input must be parameterised and interconnected as operation mode selector. You
can only connect and parameterise an operation mode selector. The OMS bit of the safety
bus must be deactivated (C15113).
The special operation can also be selected via the safety bus with the OMS bit, unless a safe
input is set as operation mode selector.
The plausibility check rejects ambiguous settings until they are parameterised correctly.

Note!
The "free traversing" setting for the special operation (C15201) motion
function must be suitable for the application!
Activation
How to activate the function:
ƒ Via a safe input which has been assigned to the function by parameterisation. In
addition, the requested operating mode depends on OMS: Function at LOW level
(C15202).
Example:
Normal operation at LOW level
The special operation is activated via a key−operated switch. The "Special operation
with LOW level" function is not permissible for a key−operated switch which uses the
special operation for short−circuiting purposes. An open circuit in the cable of the
switch would activate the special operation which is otherwise only possible with a key.
Special operation at LOW level
The special operation is active if a safety grid (safety door) is openend, i.e. the safe input
provides a LOW level and executes the parameterised stop function.
Only if no safe input is used, the function can only be activated via the safety bus:
ƒ A data telegram with corresponding contents must be transmitted to the standard
device.
