SC22-3 Safety Controller
Instruction Manual
Appendix A
A.10.2 SC22-3 Bypass Switch Hookup Options
The device(s) is shown not actuated or in the Off state .
Dual-Channel (2 terminals or 3 terminals): This circuit
typically can meet ISO 13849-1 category 2 or category 3
requirements depending on the safety rating and installation of
the bypass switch(es) . Dual-channel 3-terminal hookup uses
pulse monitoring and can detect a short circuit to another source
of power . Both 2- and 3-terminal hookup can detect a short
between channels when the contacts are open if the short is
present longer than 2 seconds .

Complementary (2 terminals or 3 terminals): This circuit can
meet ISO 13849-1 category 2, 3, or 4 requirements depending
on the safety rating and the installation of the bypass switch(es) .
This circuit can detect a short circuit between channels . In the
actuated condition (e .g ., S1 open/S2 closed, as shown below)
a short across the closed contact can cause the response
time to increase based on the debounce time . In this situation,
the response time could be longer as specified, based on the
(selected) debounce time, see Section 3 .2 .2 .
