SC22-3 Safety Controller
Instruction Manual
Overview
The Banner SC22-3 Safety Controller (the Safety Controller or
the Controller) is an easy-to-use, configurable, 24V dc safety
module designed to monitor multiple safety and non-safety
input devices and control up to three independent machine
primary control elements (MPCEs). It provides safety 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, gate interlocking switches, safety light curtains,
and other safeguarding devices. It also can be used in place
of safety PLCs and other safety logic devices when they are
excessive for the application.
Configurations are created using an Onboard LCD and
push-button interface, or using a PC connected to the Safety
Controller via a USB port.
1.1 Applications
The SC22-3 Safety Controller can be used wherever safety
modules are used. The Safety Controller is well suited to
address many types of applications, including, but not limited to:
• Two-hand control with mute function
• Robot weld/processing cells with dual-zone muting
• Material-handling operations that require multiple inputs and
bypass functions
• Manually loaded rotary loading stations
• Multiple two-hand-control station applications
• Lean manufacturing stations
1. Overview
1.2 Design and Testing
The Safety Controller was designed for up to Category 4 PL e
(ISO 13849-1) and Safety Integrity Level 3 (IEC 61508 and
IEC 62061) safeguarding applications. It has been extensively
tested to ensure that it meets the UL, IEC, and ISO product
performance requirements for both safety functionality and
operational reliability. This self-checking Safety Controller
incorporates
• Redundant microcontrollers,
• Redundant input signal detection circuitry, and
• Redundant safety output control circuitry.
It should be noted that the safety circuit performance
(e.g., categories) of a specific safety or safeguarding device(s)
will be primarily determined by the devices and their
interconnection to the SC22-3 Safety Controller. See Appendix A
for further information.

SC22-3 Safety Controller
Instruction Manual
Overview
1.4 Configuring the Safety Controller
Building a configuration for the Safety Controller is a simple
process, using one of two interfaces: the push buttons and
display on the Controller itself (the Onboard Interface, or OBI) or
the PCI software program included on the enclosed CD
(p/n 134534). The process comprises three main steps:
1. Define the safeguarding application (risk assessment).
• Determine the required devices
• Determine the required level of safety
2. Build the configuration.
• Select safety input device types and circuit connections
• Map each input to one or more safety outputs, or to other
input devices
• Set optional safety output ON- or OFF-time delays
• Select non-safety input device types and circuit connections,
if needed
• Assign status output signals, if needed
• Create configuration name, file name, date, author name,
and notes
3. Confirm the configuration.
• Controller verifies that the desired configuration is valid.
• User confirms that the configuration is what is expected.
1.4.1 Onboard Interface (OBI)
The Safety Controller can be configured using its built-in push
buttons and LCD screen, the Onboard Interface (OBI). The LCD
display provides I/O device and system status information for any
event that causes one or more of the safety outputs to turn OFF.
The display is used in conjunction with the six push buttons to:
• Create or modify password-protected configurations,
• Retrieve fault log information,
• Review device wiring detail and I/O logic relationships, and
• Display I/O device fault details and likely remedial steps.
NOTE: Onboard Interface functions are covered in more detail
in Section 5 and the OBI tutorial, Appendix C.
Accessing Fault Codes
The Fault codes are displayed in the last line of the OBI fault
diagnostics menu (see example below). Refer to Sections 5 and
8 for more information.

Overview
1.4.2 Personal Computer Interface (PCI)
The Safety Controller can also be configured using a Windows®-
based computer and the SC22-3 PC Interface (PCI) program.
This user-friendly interface makes use of icons and circuit
symbols to simplify the selection of device properties during
configuration. The configuration wiring and ladder logic diagrams
develop automatically as the configuration progresses.
Creating a configuration is simple. Once a configuration is
created, it can be stored to a computer file for archiving and
future use, or can be emailed to a remote location as an
attachment, or can be sent directly to any SC22-3 Safety
Controller or to the plug-in external memory card.
The PCI can be used to create a configuration, save it and
send it as described above, and also monitor the function of
a Controller using the live display, as well as monitor the fault
log for troubleshooting purposes. The PC Interface functions
are covered in more detail in Section 4 and the PCI tutorial,
Appendix B.

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
For further information about connecting any devices to the
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.

SC22-3 Safety Controller
Instruction Manual
Overview
Figure 1-6. Safety Outputs
1.5.2 Safety Outputs
The safety outputs are designed to control final switching
devices (FSDs) and machine primary control elements
(MPCEs) that are the last in the control chain to control the
dangerous motion. These control elements include relays,
contactors, solenoid valves, motor controls and other devices
that incorporate force-guided (mechanically-linked) monitoring
contacts, or control-reliable signals needed for external device
monitoring.
The Safety Controller has three independently controlled and
redundant solid-state safety outputs, each capable of sourcing
750 mA. The Controller‘s self-checking algorithm ensures
that the outputs turn ON and OFF at the appropriate times, in
response to the assigned input signals and the system’s self-
checking test signals.
The safety outputs, SO1, SO2 and SO3, can be controlled by
input devices with both automatic and manual reset operation.
See Section 3.6.2 for more information.
Functional Stops per IEC 60204-1 and ANSI NFPA79
The Controller is capable of performing the two functional stop
types:
• Category 0: an uncontrolled stop with the immediate
removal of power from the guarded machine
• Category 1: a controlled stop with a delay before power is
removed from the guarded machine
Delayed stops can be used in applications where, for example,
machines need power for a braking mechanism to stop the hazardous
motion. See Section 3.6.2 for more information.
ON-Delays and OFF-Delays
Each safety output can be configured to function with a time delay.
There are two types of time delays: ON-delay and OFF-delay, where
the outputs turn ON or OFF only after the time limit has elapsed. The
ON and OFF time delay limit options are from 100 milliseconds to 5
minutes, in 100 millisecond increments.
Safety output ON-delays are sometimes used when a machine
operation must be delayed before a safe machine startup is
permitted. An example application would be a robot weld cell. See
Section 3.6.2 for more information.
WARNING . . . Turning a Delayed
Output ON/OFF
If an input that is mapped to both an immediate
safety output and a delayed safety output opens
and then closes before the delay time of the delayed output has
expired, the immediate Safety Output will turn OFF and remain OFF
while the delay time is running.
At the end of the delay time, the delayed output will also turn OFF.
Both outputs will then remain OFF for about 500 ms, before they
will turn back ON. This will happen either automatically, if configured
for auto reset, or after a valid manual reset signal, if configured for
manual reset.

SC22-3 Safety Controller
Instruction Manual
Overview
1.5.3 Status Outputs
The Safety Controller has 10 configurable status outputs, used to
send non-safety status signals to programmable logic controllers
(PLCs) or to human machine interfaces (HMIs), or they may be
used to power indicator lights. These outputs can be configured
to report on the status of input devices, safety outputs, or the
Controller itself. See Section 3.7 for more information.
Signal Convention. The status output signal convention can be
configured to be 24V dc or 0V dc to indicate when:
• An input is in the Run state
• A safety output is in the ON state (see Note 1)
• The system is in a Lockout condition
• An I/O fault is present (see Note 2)
• A system reset is needed
• A safety output needs a reset (see Note 3)
• A safety input is muted
NOTES:
1. Only safety outputs that have inputs mapped to them can be
mapped to a status output.
2. An I/O fault is a failure of one or more safety inputs or safety
outputs.
3. Only safety outputs mapped to inputs configured with manual
reset logic can have a status output configured to indicate a
reset is needed.
WARNING . . . Status Outputs
The Status outputs are not safety outputs and can
fail in either the ON or OFF state. They must never
be used to control any safety critical applications. If a status
output is used to control a safety-critical application, a failure
to danger is possible and could lead to serious injury or death.
Monitored Mute Lamp Outputs
Status outputs O9 and O10 can be configured to create a
monitored mute lamp function for a mute operation. When the
mute lamp is ON, the Controller monitors for a short circuit in the
load. When the lamp is OFF, the Controller monitors for an open
circuit in the load. If an open circuit occurs before the start of
a mute cycle, the next mute cycle will be prevented. If an open
circuit occurs during a mute cycle, that mute cycle will finish, but
the next mute cycle will be prevented. If a short occurs before or
during a mute, that mute cycle will start and finish, but the next
mute cycle will be prevented. If not used to monitor a mute lamp,
these outputs may be used in the same ways as outputs O1–O8.
IMPORTANT: Only terminals O9 and O10 have the extra
monitoring circuitry needed for a monitored mute lamp. If
monitoring of the mute lamp is not required (depending on
applicable standards), any of the status outputs (O1–O10) may
be used to indicate a mute condition.
NOTE: Because of this feature, these status outputs will always
appear ON with no load (see Specifications, Section 2.2).
1.5.4 I/O Mapping: the I/O Control Relationship
The term “map” implies a control logic relationship between
an input and an output or between an input and another input,
where the state of the first input determines the state of the
output or of the second input.
• Inputs Mapped to Outputs. The following devices can be
mapped directly to the safety outputs:
– Emergency stop buttons
– Safety gate switches
– Optical sensors
– Two-hand control devices
– Safety mats
– Protective stop switches
– Rope pulls
– Enabling devices
– External device monitoring

Figure 3-1. Input and output mapping
• Inputs Mapped to Inputs. Muting sensors and bypass
switches work in conjunction with certain safety input devices
to temporarily suspend the Stop signal of a safety input device.
These sensors and switches are mapped directly to the safety
inputs; they are then indirectly mapped to the safety output(s)
that the muted safety inputs control (see Section 3.5.4).

(Operational Characteristics When Power Is Applied)
The Controller provides three power-up mode types to choose
from, to determine how the Controller will behave just after
power is supplied. These modes are: Normal, Automatic, and
Manual.
• Normal Power-Up Mode (default). In normal power-up
mode, after power is applied:
— Only those safety outputs that have automatic reset inputs
will turn ON.
— Safety outputs that have one or more manual reset inputs
will turn ON only after a manual (latch) reset operation is
performed.
— Exception: Two-hand control inputs, bypass inputs, and
enabling device inputs must be seen to be in the Stop
state at power-up, regardless of the power-up mode
selection. If these are seen to be in the Run state at
power-up, the outputs will remain OFF.
• Automatic Power-Up Mode. In automatic power-up mode,
after power is applied:
— All safety outputs will turn ON immediately if the inputs
that are mapped to these outputs are all in the Run state.
— Exception: Two-hand control inputs, bypass inputs, and
enabling device inputs must be seen to be in the Stop
state at power-up, regardless of the power-up mode
selection. If these are seen to be in the Run state at
power-up, the outputs will remain OFF.
CAUTION . . . Automatic Power-Up
When the Controller is configured for automatic
system reset power-up mode, the Controller acts as
if all input devices are configured for auto (trip) reset. Each safety
output will immediately turn on at power-up if the assigned
input devices are all in the Run state, even if one or more
of the input devices is configured for manual (latch) reset. If
the application requires that a manual (latch) reset operation be
performed before the safety output turns ON, then either manual or
normal power-up mode configuration must be used. Failure to do
so could cause a machine to operate in an unexpected way at
power-up or after temporary power interruptions.
• Manual Power-up Mode. In Manual Power-up Mode, after
power is applied:
— Safety outputs will turn ON only after all inputs mapped
to this output are in the Run state and a System
Reset has been performed. (A manual latch reset is not
required.)
— Exception: Two-hand control inputs, bypass inputs, and
enabling device inputs must be seen to be in the Stop
state at power-up, regardless of the power-up mode
selection. If these are seen to be in the Run state at
power up, the outputs will remain OFF.
Mute on Power-Up Enable
If configured, the Mute on Power-Up function will initiate a mute
cycle after power is applied to the SC22-3 if the muted safety
inputs are active (Run state or closed), and either M1-M2 or M3-
M4 (but not all four) are signaling a muted condition (e.g., active
or closed). (See Section 3.5.4.)
CAUTION . . . Controller Operation
on Power-Up
It is the responsibility of the person who
configures, installs, and/or maintains the Controller to
assess what safeguarding devices and methods are
appropriate for any given machine or application and to be
aware that the power-up behavior of this Controller may not
be obvious to the machine operator.
Monitored System Reset
Monitored System Reset is enabled by default and requires an
OFF-ON-OFF signal at the reset input, where the ON-duration
must be between 0.3 and 2 seconds (trailing edge reset), in
order to reset the system.
If unchecked (Monitored System Reset disabled), the reset input
requires only a signal from OFF to ON (leading edge reset), in
order to reset the system.

SC22-3 Safety Controller
Instruction Manual
Overview
1.7 Internal Logic
The Controller’s internal logic is designed so that a safety output
can turn ON only if all the controlling input device signals are in
the Run state and the Controller’s self-check signals are in the
No-Fault state.
Safety
Input 1
Safety
Input 2
Safety
Controller
Safety
Output 1
Stop Stop Run (No Fault) OFF
Stop Run Run (No Fault) OFF
Run Stop Run (No Fault) OFF
Run Run Run (No Fault) ON
The table above illustrates the logic for two safety input devices
mapped to control Safety Output 1. If any of the safety input
devices are in the Stop state, then Safety Output 1 is OFF.
When both safety inputs are in the Run state, then Safety
Output 1 will turn ON.
1.7.1 Additional Functions
Other logic functions are slight variations of the general AND
logic rule set.
• Two-Hand Control: The machine initiation signal
incorporating a 0.5 second actuator simultaneity limit and
anti-tie-down logic, designed to prevent single-actuator
machine cycle operation.
• Safety Device Muting: The automatic suspension of one or
more safety input Stop signals during a portion of a machine
operation when no hazard is present or when access to the
hazard is otherwise safeguarded.
• Safety Device Bypass: The manually activated, temporary
suspension of one or more safety input Stop signals when
the hazard is otherwise safeguarded.
• Enabling Device Control: The actively controlled manual
suspension of a Stop signal during a portion of a machine
operation when a hazard could occur.
The rules that apply to these special cases are explained in
Appendix A.
1.8 Password Overview
To provide security, the Safety Controller requires use of a
password in some cases. For information about changing a
Controller’s password, refer to Sections 4.2.1 (PCI) and 5.3.4
(OBI).
NOTE: If the password becomes lost, contact the Factory for
assistance.
Creating a Configuration
• Via computer using the SC22-3 PC Interface (PCI) program
(no password needed)
• Via the Controller Onboard Interface (OBI)
(password needed)
Confirming a Configuration
• Via the PCI, using the PC connected to a powered Controller
(password needed)
• Via the OBI, on a powered Controller (password needed)
Sending a Confirmed Configuration to the Controller
• Via a direct connection between the PC and the Controller,
using the SC-USB1 cable and the PC Interface program
(password needed)
• Via the PC, the XM card programming tool, and the XM card
(password needed)
1.9 Confirming a Configuration
Although a Controller will accept an unconfirmed configuration,
it will only activate it (adopt the configuration and function
according to its parameters) after the configuration is confirmed,
using the OBI.
IMPORTANT: If any modification is made to a confirmed
configuration, or if a configuration is edited during the
confirmation process, the PCI and the Controller will recognize
this modified configuration as being new and will require it to be
confirmed before it can be activated and used.
Once confirmed, a configuration can be stored and reused
without reconfirmation. The configuration code will be validated
automatically each time it is downloaded to a Controller and
whenever the Controller powers up. Configurations, confirmed
or not, can be sent via email. Sending (downloading) a new
confirmed configuration to a Controller requires entry of the
Controller password.

SC22-3 Safety Controller
Instruction Manual
System Installation
3. System Installation
3.1 Appropriate Application
The correct application of the SC22-3 Safety Controller is
dependent on the type of machine and the safeguards that are
to be interfaced with the Controller. The Controller is generally
interfaced with safeguards that may be used only on machinery
that is capable of stopping motion immediately upon receiving a
stop signal and at any point in its machine cycle. It is the user’s
responsibility to verify whether the safeguarding is appropriate for
the application and is installed as instructed by the appropriate
installation manuals.
If there is any doubt about whether or not your machinery is
compatible with this Controller, contact Banner’s Application
Engineers at the factory.
WARNING . . .
This SC22-3 Safety Controller is not a stand-
alone point-of-operation guarding device, as
defined by OSHA regulations. It is necessary to install point-of-
operation guarding devices, such as safety light screens and/or
hard guards, to protect personnel from hazardous machinery.
Failure to install point-of-operation guards on hazardous
machinery can result in a dangerous condition which could
lead to serious injury or death.
WARNING . . . User Is Responsible
for Safe Application of this Product
The application examples described in this
document depict generalized guarding situations. Every
guarding application has a unique set of requirements.
Extreme care is urged to ensure that all legal requirements
are met and that all installation instructions are followed. In
addition, any questions regarding safeguarding should be
directed to the factory applications department at the number
or addresses listed on the front cover.
WARNING . . . Shock Hazard
Always disconnect power from the Safety
Controller and the guarded machine before
making any connections or replacing any component. Electrical
installation and wiring must be made by qualified personnel and
must comply with the NEC (National Electrical Code), IEC 60204-1
and -2, and all applicable local standards and codes.
WARNING . . . Read this Section
Carefully Before Installing the System
The Banner SC22-3 Safety Controller is an
accessory device that is typically used in conjunction with a
machine safeguarding device. Its ability to perform this function
depends upon the appropriateness of the application and
upon the Safety Controller’s proper mechanical and electrical
installation and interfacing to the machine to be guarded.
If all mounting, installation, interfacing, and checkout
procedures are not followed properly, the Safety Controller
cannot provide the protection for which it was designed.
The user has the responsibility to ensure that all local, state, and
national laws, rules, codes, or regulations relating to the installation
and use of this control system in any particular application are
satisfied. Extreme care should be taken to ensure that all legal
requirements have been met and that all technical installation
and maintenance instructions contained in this manual are
followed. Read Section 3 (and its subsections) of this manual
carefully before installing the system. Failure to follow these
instructions could result in serious bodily injury or death.
The user has the sole responsibility to ensure that this Safety
Controller is installed and interfaced to the guarded machine by
Qualified Persons (see Glossary), in accordance with this manual
and applicable safety regulations.

SC22-3 Safety Controller
Instruction Manual
System Installation
3.2 Safety Input Devices
Safety input devices allow for the cessation of motion, or an
otherwise hazardous situation, by controlling the safety outputs
of the SC22-3. A safety output in the Off state results in a stop
of motion and removal of power from the machine actuators
(assuming this does not create additional hazards).
For a safety output to turn ON, all of its controlling safety
input devices must be in their Run state. A few special safety
input device functions can, under predefined circumstances,
temporarily suspend the safety input “stop signal” to keep the
safety output ON (e.g., muting and bypassing).
The SC22-3 input configurations, depending on the type, have
means to detect failures and faults that would otherwise result in
a loss of that control of the safety function. Once such a failure
or fault is detected, the Safety Controller will lock out until the
problem is fixed.
Other input configurations do not have this detection capability.
It is recommended that in all circumstances the installation of
the SC22-3 Safety Controller and its associated safety and
safeguarding devices be installed to eliminate or minimize the
possibility of failures and faults that could result in the loss of the
safety function(s).
Methods to eliminate or minimize the possibility of these failures
include, but are not limited to:
• Physically separating interconnecting control wires from each
other and from secondary sources of power.
• Routing interconnecting control wires in separate conduit, runs,
or channels.
• Locating all elements (modules, switches, and devices under
control) within one control panel, adjacent to each other, and
directly connected with short wires.
• Properly installing multi-conductor cabling and multiple wires
through strain-relief fittings. (Over-tightening of a strain-relief
can cause short circuits at that point.)
• Using positive-opening or direct-drive components, installed
and mounted in a positive mode.
WARNING . . . Failures and Faults
The SC22-3 Safety control can be interfaced
with input devices at differing levels of integrity
as described in Appendix A. The user must conduct a Risk
Assessment to determine the appropriate level of integration. The
user also must eliminate or minimize the possibility of failures
and faults that could result in the loss of the safety function(s).
3.2.1 Signals: Run and Stop States
Dual-channel safety input devices have two separate signal
lines. Dual-channel signals for some devices are both positive
(+24V dc) when the device is in the Run state. Others have a
complementary circuit structure where one channel is at 24V dc
and the other is at 0V dc when the device is in the Run state.
For the sake of clarity, instead of referring to a safety input
device as being “ON” (e.g., 24V dc) or “OFF” (e.g., 0V dc), this
manual adopts the Run state/Stop state convention.
3.2.2 Safety Input Device Properties
The Controller can be configured to accommodate many types
of safety input devices. However, a number of device properties
must be established (using either the OBI or PCI interface) so
that the Controller can properly monitor their signals. These
configurable properties include:
• Device name — This is generated automatically by the
Controller and can be changed by the user.
• Circuit type — The circuit and signal convention options that
can be selected to define the input device.
• Reset logic — Automatic (Trip mode) or Manual (Latch mode).
• Terminal number — The assignment of input terminals for a
device.
• I/O mapping — The logic control relationship between inputs
and outputs or between inputs.
• Signal change-of-state — Simultaneous or Concurrent type,
and signal convention (high or low)
• Signal debounce time — The signal state transition time.
• Start-up test — An optional precautionary safety input device
test required after each power-up
• Function time limit — The adjustable time limit within which a
function is allowed to operate
• Muteable — Whether or not the device can be muted.
• Bypassable — Whether or not the device can be bypassed.

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.
