The SR750/760 Tabular screen offers a tab labeled LOGIC. This tab allows you to access the SR750/760's 20 logic inputs. You can use these logic inputs to operate a variety of logic functions for circuit breaker control, external trips, blocking of protection elements, etc., and use the PCMS Wizard to monitor the status of the logic inputs. For more information, refer to the SR750 or SR760 user manual, in the section titled Setpoints - S3 Logic Inputs.
The SR750/SR760 Tabular Data Screen Wizard supports the Lockout/Tagout wizard. Please refer to the section titled Using and Configuring PMCS Wizards: Lockout/Tagout Wizard for details.
If a Danger or Ground Lockout/Tagout symbol is installed on this wizard, attempts to issue a Breaker Open or Breaker Close command will generate an error message.
See the SR750/760 Feeder Management Relay Instruction Manual (Chapter 5, Actual Values) for information on the display of data values under different device configurations. Values not configured for use are displayed as N/A.
