Operation
Programming the safety monitor parameters defines the safety function of the device. Read the
corresponding documentation.
6.1
Safety-Related Inputs
The module generates an internal code sequence. This sequence is monitored by a safety
monitor (additional bus device) to ensure the correct order.
The status of the externally connected mechanical switches controls the code sequence trans-
mission. To ensure the safe state of the device, use switches with a safety function with positive
opening operation. The code sequence is interrupted by actuating the switch.
The two input channels on the safety module are independent. The safety monitor must be
parameterized to monitor that the two inputs are synchronous for dual-channel applications of
category 4/PL e as per ISO 13849-1 or SIL 3 as per EN/IEC 62061.
6.2
Conventional (Non-Safe) Electronic Outputs
The outputs are designed in line with the AS-Interface standard. Positive potential (PNP tech-
nology) is switched for these outputs.
•
The output is controlled directly by data bits D0 and D1 of the AS-Interface master.
Communication monitoring:
•
In the event of a communication failure, the outputs are disconnected from the power
supply.
•
Do not use the conventional output for safety functions.
•
Make sure that the individual cable ends of the connection lines do not touch each other.
