RESOLUTION
Check for proper connection and 10 Vdc to 28
Vdc to "+" and "-" terminals per Section 6.3
Check for proper connection of power: "+" and
"-" terminals per Section 6.3
Replace WDRR
Check LED operation per Section 6.2 and replace
WDRR if necessary
Determine source for ESD/EMI emissions in
application and take action to remove
• Determine which Limitless™ input has a low
battery using the procedure in Section 6.5
• Replace Limitless™ switch battery per
Limitless™ input Installation guide
