SC22-3 Safety Controller
Instruction Manual
Overview
1.5 Input and Output Devices
1.5.1 Safety and Non-Safety Input Devices
The Safety Controller has 22 input terminals that can be used to
monitor either safety or non-safety devices; these devices may
incorporate either solid-state or contact-based outputs . Each of
these 22 input terminals can either monitor an input signal or
provide 24V dc . The function of each input circuit depends on
the type of device connected to it; this function is established
when the Controller is configured .
For general and specific information about input devices,
their requirements, hookup options and appropriate warnings
and cautions, additional installation information (e .g ., Safety
Distance), refer to Section 3 and Appendix A . Appendix A
contains hookup information and other useful information about
integrating the following devices:
• Safety Circuit Integrity — Section A .1
• Protective (Safety) Stop — Section A .2
• Optical Sensors — Section A .3
• Safety Gate (Interlock Guard) — Section A .4
• Two-Hand Control — Section A .5
• Safety Mat (Edges) — Section A .6
• Emergency Stop Push Buttons — Section A .7
• Rope (Cable) Pull — Section A .8
• Enabling Devices (Pendants) — Section A .9
• Bypass — Section A .10
• Muting — Section A .11

Safety Controller, contact Banner Engineering .
Safety Device Hookup Considerations
The inputs of the SC22-3 Safety Controller can be configured
to interface with many types of safety devices, including
safeguarding devices (e .g ., safety light curtains), complementary
protective equipment (e .g ., emergency stop push buttons),
and other devices that impact the safe use of a machine (e .g .,
equipment protection) .
The way these devices interconnect impacts their ability to
exclude or detect faults that could result in the loss of the
safety function . There are many standards, regulations and
specifications that require certain capabilities of a safety circuit .
WARNING. . .
The user is responsible for ensuring that all local,
state, and national laws, rules, codes, and regulations
relating to the use of the Safety Controller in any particular
application are satisfied . Extreme care is urged that all legal
requirements have been met and that all installation, operation, and
maintenance instructions contained in the safety device manual
from the manufacturer and in this manual are followed .
