in excess of 6 ms (=default closed-to-open debounce time) must
be added to the stated response; refer to Specifications, Section
2 .2 .)
A.4.2 Optical Sensor Generic Hookup
All figures show the optical sensor actuated, in the Normally
Open, or OFF, state .
Single-Channel (1 terminal, 2 terminals or PNP device):
These circuits can typically meet ISO 13849-1 Category 2
requirements, depending on the safety rating of the input
device(s) . At a minimum, a safety-rated device must be used
to achieve a Category 2 level of safety . The 1-terminal and the
PNP device can not detect a short circuit to another source of
power . Two-terminal hookup uses pulse monitoring and can
detect a short circuit to another source of power . Fault Exclusion
must be used to achieve higher level of safety circuit integrity .

Dual-Channel (2 terminals or 3 terminals): This circuit typically
can meet ISO 13849-1 Category 2 or 3 requirements, depending
on the safety rating and installation of the input device(s) . 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 input device .
This circuit can detect a short circuit between channels . In the
actuated condition (e .g ., S1 open/S2 closed 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 .
