Table 33: Connecting testable type 2 single-beam safety light barriers
Electrical connection: Example from samosPLAN5+
SLB type 2
Test input TE (transmitter) at T1
Output Q (receiver) at I3
ATTENTION
Note the safety information and protective measures!
Route the transmitter and receiver lines outside of the switchbox so that a short-circuit
between these lines can be avoided, e.g. route them separately in separate sheathed cables
or protected areas.
