5.6 CONTROL ELEMENTS
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 3-bit word to the external device and SCADA via out-
put 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 3-bit control input.
Make the following changes to Setting Group Control in the
SETTING GROUPS FUNCTION:
SETTING GROUPS BLK:
GROUP 2 ACTIVATE ON:
GROUP 3 ACTIVATE ON:
Make the following changes to Selector Switch element in the
menu to assign control to User Programmable Pushbutton 1 and Contact Inputs 1 through 3:
SELECTOR SWITCH 1
SELECTOR 1 FUNCTION:
SELECTOR 1 FULL-RANGE:
SELECTOR 1 STEP-UP MODE:
SELECTOR 1 TIME-OUT:
SELECTOR 1 STEP-UP:
SELECTOR 1 ACK:
Now, assign the contact output operation (assume the H6E module) to the Selector Switch element by making the following
changes in the
SETTINGS

OUTPUT H2 OPERATE:
OUTPUT H3 OPERATE:
Finally, assign configure User-Programmable Pushbutton 1 by making the following changes in the
SETUP USER-PROGRAMMABLE PUSHBUTTONS
PUSHBUTTON 1 FUNCTION:
PUSHBUTTON 1 DROP-OUT TIME:
The logic for the selector switch is shown below:
