Complementary (PNP device): This circuit can meet ISO
13849-1 Category 2, 3, or 4 requirements, depending on the
design and installation of the switch(es) . This circuit can detect a
short circuit between channels . In the guard closed condition (as
shown) 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 than specified,
based on the (selected) debounce time, see Section 3 .2 .2 .

A.4 Optical Sensor
The SC22-3 safety inputs may be used to monitor
optical-based devices that use light as a means of
detection .
Safety Circuit Integrity Levels
Requirements vary widely for the level of control reliability or
safety category per ISO 13849-1 (EN954-1) in the application
of optical safeguarding . While Banner Engineering always
recommends the highest level of safety in any application, it
is the responsibility of the user to safely install, operate and
maintain each safety system and comply with all manufacturer
instructions and all relevant laws and regulations .
The safety performance (integrity) must reduce the risk
from identified hazards as determined by the machine’s risk
assessment . See Section A .1 for guidance if the requirements as
described by ISO 13849-1 (EN954-1) are to be implemented .
In addition to the requirements stated in this section, the design
and installation of the optical safeguarding device should comply
with ANSI B11 .19 or IEC61496 (all parts) .
A.4.1 Optical Sensor Requirements
When used as safeguarding, these devices are described by
IEC61496-1/-2/-3 as “active Opto-electronic protective device”
(AOPD) and “active opto-electronic protective device responsive
to diffuse reflection” (AOPDDR) .
AOPDs include safety light screens (curtains) and safety grids
and points (multiple-/single-beam devices) . These devices are
described as meeting Type 2 or Type 4 design requirements; a
Type 2 device is allowed to be used in a Category 2 application,
per ISO 13849-1, and a Type 4 device can be used in a
Category 4 application .
AOPDDRs can also be area or laser scanners . The primary
designation for these devices is a Type 3, for use in up to
Category 3 applications .
Warning …
Incomplete Information
Many installation considerations necessary to
properly applying these devices are not covered
by this document .
Refer to the appropriate device installation
instructions to ensure the safe application of the device.
Optical safety devices also must be placed at an appropriate
separation distance, according to applicable standards . Because
these devices vary, it is not practical to list specific calculations
here . Refer to the applicable standards and to manufacturer
documentation specific to your device for the appropriate
calculations; for the purpose of the calculation, Safety Controller
default response is 0 .010 seconds, plus any additional closed-to-
