tion/cascading
Possible; note max. line resistance of 100 µ and correct setting of
test pulse time
Discrepancy time
Preset at 1500 ms
NOTICE
You can find additional information in the operating instructions for the magnetic safety swit-
ches.

Info
Testing Necessary with serial inductive switches
Series connec-
tion/cascading
Inductive switches (serial):
Up to six sensors per input. 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
and the correct setting of the test
pulse time.
Inductive switch: No cascading possible

ches.
