1.3.11.3 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
Special operation is activated via a 2−pole key−operated switch. The "Special operation
with LOW level" function is not permissible for a key−operated switch which uses
special operation for purposes of short−circuiting. An open circuit in the cable of the
switch would activate special operation.
Special operation at LOW level
Special operation is active when the safe input detects the LOW level. This triggers
execution of the stop function parameterised.
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.
