switches
4.3.1

Testable Type 2 single-beam photoelectric safety switches

Electrical connection: Example from Setting and Monitoring Tool with WS0-XTIO
SICK Wx12/18/24/27,
Vx18
SICK L21, L27/L28
Use protected or separate cabling for the test output of the module (X1...X8) to the test
input of the transmitter and for the output of the receiver to the safe input of the
module (I1...I8). Otherwise a cross circuit between these signals can inhibit the error
detection by this test.
Possible for T4000 Compact
Not necessary for T4000 Direct, since self monitored
T4000 Compact is not cascadable;
Take the max. line resistance of 100 Ω into account at the T4000
(see Chapter 12)
