APPLICATION EXAMPLE
Consider an application where the selector switch is used to control setting groups 1 through 4 in the relay. The setting
groups are to be controlled from both user-programmable pushbutton 1 and from an external device via contact inputs 1
through 3. The active setting group shall be available as an encoded three-bit word to the external device and SCADA via
output contacts 1 through 3. The pre-selected setting group shall be applied automatically after 5 seconds of inactivity of
the control inputs. When the relay powers up, it should synchronize the setting group to the three-bit control input.
Make the following changes to setting group control in the
