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.
