5.13 E-Stop linkage
Through linkage, the behavior of the safety sensor can be controlled via a two-channel safety circuit.
The upstream safety devices and operational controls perform safety-relevant switch-off of the safety-re-
lated switching outputs of the safety sensor.
The following upstream sensors and operational controls are possible regarding the linkage:
• Safety device with two-channel contact-based switching output (normally closed contact), e.g. safety
switch, E-Stop rope switch, safety position switch and the like (see chapter 5.13.1 "Contact-based
safety circuit").
• Safety device with two-channel electronic OSSD switching output (see chapter 5.13.2 "Linkage of elec-
tronic safety-related switching outputs").
E-Stop buttons connected to the safety sensor act only on the safety circuit to which the AOPD is assigned.
Thus, it can be considered to be an area E-Stop. The regulations for E-Stops apply to it, including those in
accordance with EN60204-1 and ENISO13850, among others.
Ä In this case, observe the regulations for E-Stops.
If linkage is utilized, the response time of the linked device is extended by 20ms.
Ä Take the extended response time into account when calculating the safety distance.
NOTICE
Extended response time in combination with an internal safe switching delay!
If the E-Stop linkage is used in combination with the internal safe time delay (see chapter 5.11
"Internal safe time delay"), the response time of the delayed switch-off increases by up to
40ms.
Ä Take the extended response time of the delayed switch-off into account when configuring
the system.
5.13.1 Contact-based safety circuit
This function switches off the safety-related switching outputs of the safety sensor by means of an up-
stream 2-channel contact-based safety circuit, e.g. by means of safety switches with separate actuators.
The safety sensor only switches on if the following conditions have been fulfilled:
• The protective field is free.
• The safety circuit is closed or both contacts have been closed simultaneously within 0.5s.
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").
