5.4.2 Non-contact safety switches
5.4.2.1 Magnetic safety switches (e.g., RE)
Table 65: Connection of magnetic safety switches with equivalent inputs (RE13, RE27)
Electrical connection: example with FX3-XTIO
At test output Channel 1: contact between X1 and I1
Channe
l 2: contact between X2 and I2
Table 66: Connection of magnetic safety switches with complementary inputs (e.g., RE11, RE21,
R
E31, RE300)
Electrical connection: example with FX3-XTIO
At test output N/C contact between X1 and I3
N/O cont
act between X2 and I4
Table 67: Functions with magnetic safety switches
Function Notes
Tested Possible
Series connec‐
t
ion/cascading
Possible; note max. conductor resistance of 100 Ω and ensure test
signal time is set correctly
Discrepancy time Pre-setting: 1.5s, see the report in the configuration software
NOTE
You will find more information in the operating instructions for the magnetic safety
switches.
5.4.2.2 Inductive safety switches IN4000 and IN4000 Direct
Table 68: Connection of inductive safety switches
Electrical connection: example with FX3-XTIO
IN4000 Test input TI (IN4000) at X1
Out
put Q (IN4000) at I1
IN4000 Direct (with OSSD) OSSD1 (IN4000) at I3
O
SSD2 (IN4000) at I4
Table 69: Functions with inductive safety switches
Function Notes
Tested Necessary on the IN4000
Series connec‐
t
ion/cascading
IN4000 Direct cannot be cascaded
IN4000: up to 6 sensors per input
Maximum switch-on delay of the cascade: 10ms (otherwise the test
pulse width leads to shutdown)
Note max. conductor resistance of 100 Ω and ensure test signal time is
set correctly
