The Safety Subsystem

The main function of the safety subsystem is to control the motor bus power relays and to report 
the status of the safety subsystem. This functionality includes:

•

Motor Bus Power Relays

•

Alternate Relays

•

Emergency Stop Button

•

Safety Mat

•

Optical Sensor

•

Enabling Device

•

Software Input Switches

•

Bus Monitoring

•

Access Switch

•

I/O Controller Interface

The functions in italics are optional and these devices are available from third party manufacturers. 
They are not included with the Sawyer robot.

The Banner Safety Controller itself is rated to PLe CAT 4 per ISO 13849-1:2006, and the motor 
safety relays are rated to PLd Cat3. The combined safety function comprised by these safety 
devices meets PLd Cat 3.
