SC22-3 Safety Controller
Instruction Manual
System Installation
Circuit Types: Contact and Solid State Circuits
The table below depicts many of the input devices and circuit
types the Controller can monitor . It highlights which of these
properties can be configured, and for which devices . More
description of some of these topics is included in the following
paragraphs .
NOTE: Not all circuit types meet the Category 4 classification
per ISO 13849-1; refer to Appendix A (Section A .1) for a
discussion of safety circuit integrity levels .
Reset Logic: Manual or Automatic Reset
Safety input devices can be configured to require a manual reset
before the safety output(s) they control are permitted to turn back
ON . This is sometimes referred to as “latch” mode because the
safety output “latches” to the OFF state until a reset is performed .
If a safety input device is configured for automatic reset or “trip”
mode, the safety output(s) it controls will turn back ON when the
input device changes to the Run state (provided that all other
controlling inputs are also in the Run state) .
Reset rules and types are discussed in Section 3-4 .
Terminal Numbers: Connecting the Input Devices
The Controller needs to know what device signal lines are to
be connected to which wiring terminals, so that it can apply the
proper signal monitoring methods, Run and Stop convention,
timing rules, and fault rules . Although terminals are assigned
automatically during the configuration process, the terminal
assignments can be changed manually, using either the Onboard
Interface or the PC Interface .
