Testable single-beam safety light barriers
888486027
Testable type 2 single-beam safety light barriers
888487563
Table 37: Connecting testable type 2 single-beam safety light barriers
Electrical connection: Example from samosPLAN 6
SLB Typ 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.
Table 38: Functions with testable type 2 single-beam safety light barriers
Function Info
Testing Possible
Series connec-
tion/cascading Possible, depending on the safety light barrier type used
Note the correct setting of the test pulse time: Maximum OFF-ON
delay of the cascade is 10 ms (otherwise, the test gap will lead to
switch-off).
Note the maximum line resistance of 100
Ω
.
NOTICE You can find additional information in the operating instructions for the type 2 single-beam
safety light barriers.
