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
SETTINGS CONTROL ELEMENTS SETTING GROUPS
menu:
SETTING GROUPS FUNCTION:
“Enabled”
GROUP 4 ACTIVATE ON:
“SELECTOR 1 POS 4"
SETTING GROUPS BLK:
“Off”
GROUP 5 ACTIVATE ON:
“Off”
GROUP 2 ACTIVATE ON:
“SELECTOR 1 POS 2"
GROUP 6 ACTIVATE ON:
“Off”
GROUP 3 ACTIVATE ON:
“SELECTOR 1 POS 3"
Make the following changes to Selector Switch element in the
SETTINGS CONTROL ELEMENTS SELECTOR SWITCH
SELECTOR SWITCH 1
menu to assign control to User Programmable Pushbutton 1 and Contact Inputs 1 through 3:
SELECTOR 1 FUNCTION:
“Enabled”
SELECTOR 1 3BIT A0:
“CONT IP 1 ON”
SELECTOR 1 FULL-RANGE:
“4”
SELECTOR 1 3BIT A1:
“CONT IP 2 ON”
SELECTOR 1 STEP-UP MODE:
“Time-out”
SELECTOR 1 3BIT A2:
“CONT IP 3 ON”
SELECTOR 1 TIME-OUT:
“5.0 s”
SELECTOR 1 3BIT MODE:
“Time-out”
SELECTOR 1 STEP-UP:
“PUSHBUTTON 1 ON”
SELECTOR 1 3BIT ACK:
“Off”
SELECTOR 1 ACK:
“Off”
SELECTOR 1 POWER-UP MODE:
“Synchronize”
Now, assign the contact output operation (assume the H6E module) to the Selector Switch element by making the following
changes in the
SETTINGS INPUTS/OUTPUTS CONTACT OUTPUTS
menu:
OUTPUT H1 OPERATE:
“SELECTOR 1 BIT 0"
OUTPUT H2 OPERATE:
“SELECTOR 1 BIT 1"
OUTPUT H3 OPERATE:
“SELECTOR 1 BIT 2"
Finally, assign configure User-Programmable Pushbutton 1 by making the following changes in the
SETTINGS PRODUCT
SETUP USER-PROGRAMMABLE PUSHBUTTONS USER PUSHBUTTON 1
menu:
PUSHBUTTON 1 FUNCTION:
“Self-reset”
PUSHBUTTON 1 DROP-OUT TIME:
“0.10 s”
