2 Product Description
Safety control is a critical and required part of any safety system. This is because safety controllers ensure that your safety
measures 1) do not fail, or 2) if failure is inevitable, fail in a predictable safe way.
A safety controller is often an ideal safety control solution, because it provides more functionality than a safety relay, at a
lower cost than a safety PLC. In addition, a smart, scalable safety controller can expand with your needs as well as enable
remote monitoring of your machine safety systems.
Banner Safety Controllers are easy-to-use, configurable, and expandable modules (XS26-2xx models) designed to monitor
multiple safety and non-safety input devices, providing safe stop and start functions for machines with hazardous motion.
The Safety Controller can replace multiple safety relay modules in applications that include such safety input devices as E-
stop buttons, interlocking gate switches, safety light curtains, two-hand controls, safety mats, and other safeguarding
devices. The Safety Controller may also be used in place of larger and more complex safety PLCs with the use of additional
input and/or output expansion modules.
The onboard interface:
• Provides access to fault diagnostics
• Allows reading and writing the configuration file from and to the SC-XM2 and SC-XM3 drives
• XS/SC26-2: Displays configuration summary, including terminal assignments and network settings
2.1 Terms Used in this Manual
The following terms are used in this manual.
Safety Controller—an abbreviated version referring to the entire XS/SC26-2 Safety Controller system, as well as to the
SC10-2, both of which are covered by this manual
Expandable Safety Controller—refers to expandable models
Base Controller—refers to the main module in the XS/SC26-2 Safety Controller System
SC26-2 Programmable Safety Controller, XS26-2 Programmable Safety Controller, XS2so and XS4so Solid-State Safety
Output Modules, XS8si and XS16si Safety Input Modules, XS1ro and XS2ro Safety Relay Modules—formal name of the
XS/SC26-2 product line
2.2 Software
The Banner Safety Controller Software is an application with real-time display and diagnostic tools that are used to:
• Design and edit configurations
• Test a configuration in Simulation Mode
• Write a configuration to the Safety Controller
• Read the current configuration from the Safety Controller
• Display the real-time information, such as device statuses
• Display the fault information
The Software uses icons and circuit symbols to assist in making appropriate input device and property selections. As the
various device properties and I/O control relationships are established on the Functional View tab, the program
automatically builds the corresponding wiring and ladder logic diagrams.

2.3 USB Connections
The micro USB port on the Base Controller and the SC10-2 is used to connect to the PC (via the SC-USB2 cable) and the
SC-XM2/3 drive to read and write configurations created with the Software.
CAUTION: Potential for Unintended Ground Return Path
The USB interface is implemented in an industry standard way and is not isolated from the 24 V supply.
The USB cable makes it possible for the computer and safety controller to become part of an unintended
ground return path for other connected equipment. A large current could damage the PC and/or the
Safety Controller. To minimize this possibility, Banner recommends that the USB cable is the only cable
connected to the PC. This includes disconnecting the AC power supply to a laptop whenever possible.
The USB interface is intended for downloading configurations and temporary monitoring or
troubleshooting. It is not designed for continuous use.
