function blocks
The safety door circuitry of
SG1
shuts down output
Q3,Q4
on the SA-BM-S1.
SG2
and
SG3
shut down the independent
Q1
and
Q2
/
Q3, Q4
of the right SA-BM-S1. When
ES1
(emergency stop) is actuated the internal
AND
link in the SA-BM-S1 function block and
the connection of output
Q2
on the SA-BM-S1 with the
EN
enabling input on the right SA-
BM-S1 ensure complete shutdown of all outputs.
OR-linked safety inputs (sensor inputs)
Actuation of lockswitch
S1
bridges the safety door function with an
OR
link; i.e. all outputs
Q1
to
Q4
remain on. Lockswitch takes effect even with safety door opened and switches
all outputs on.
