NOTE!
The polarity of the switching behavior of the safe outputs is parameterizable. If output
„High-Active“, referring to the closed-circuit principle, is used (= setting in
ProSafePara "Not inverted"), it must be considered a monitoring function, only. If the
output is „Low-Active“ (= default setting in ProSafePara „inverted“), the safety chain,
according to the closed-circuit principle can be generated.
Application case for such a safety chain is a STO-function, which is connected in
series via several drives. They are controlled centrally via the control of the first drive
in the chain.
Other application cases depend on the accordant application.
The closed-circuit principle implies that the safety function is always activated /
enabled, if the voltage at the assigned safe input is "Low".This can occur, if a
connected cable at the safe input is pulled off.

Crossfault detection / Short-circuit detection
A crossfault detection to other outputs or to the operating supply voltage potentials for the
cables is assured by diagnostic functions and the construction of the hardware.
So that the crossfault detection does not generate wrong error messages, the capacitive
load of the safe input, which is connected to the output may be 15 nF, at maximum.

C.2.2 Technical data safe outputs
11.3.5 Cycle Outputs
The Safety Module has 4 cycle outputs, makes sure that there is a crossfault detection in
the external wiring of the safety devices.
Features
m
Current-limited and short-circuit proof
m
At use of electro-mechanical switches or sensors, the clock signals provide detection
of short-circuits of the connection cables and of the periphery devices to other cables
or of any other potentials in the system
WARNING!
Cycle output A group 1 and cycle output A group 2 have an identical phase position.
A trouble shooting takes place only between the cycle outputs A and B. Between
these signals there is a phase shift of 90°.
