5.13.2 Linkage of electronic safety-related switching outputs
This function is used to construct a serial connection of devices with electronic safety OSSD switching out-
puts. The OSSDs of an upstream safety device switch off the safety-related switching outputs of the safety
sensor as a central safety device. Regarding the downstream safety circuit, a linked system behaves like a
single device, i.e. only inputs are necessary in the downstream safety relay.
The following conditions have to be fulfilled for the OSSDs to switch on:
• The protective field must be free.
• The OSSDs of the upstream device must be switched on or have been switched on simultaneously
within 0.5s.
NOTICE
A contact-based safety sensor, e.g. a safety switch with two positive-guided normally closed
contacts, can be switched in the safety circuit when linking electronic safety-related switching
outputs.
Ä If this switch opens, it must close both circuits again simultaneously within a time tolerance
of 0.5s. A message will otherwise be displayed on the safety sensor.
Activation of the function
Ä Activate the linkage using the configuration and diagnostics software (see chapter 9.4.3 "Activating pro-
tective function and contactor monitoring").
5.14 Signaling functions
The device and monitoring functions of the safety sensor deliver indication signals for the following function
groups:
• Protective functions, e.g.
• Protective field violated
• Warning field violated
• Field pair changeover active
• Device functions
• Error messages
• Warnings
• Diagnosis
The assignment of the individual functions within the function groups to the indication signals is defined us-
ing the configuration and diagnostics software (see chapter 9.6 "Configuring signal outputs").
For an overview of all logic and electrical signals of the safety sensor, see chapter 15.4 "Representation of
safety sensor status".
