Hello All,

This is my very first post here.

I am very new to SEL settings and I am currently working on a 351S relay setting. I received the following question from client "Which timer(s) is for returning to normal? We would like it adjusted to 30 minutes and verified during commissioning". I am not sure what is the setting that he is talking about. He said it is in Auto Mode. Do any of you guys have any hint what he means?

Reset Timer
The reset timer qualifies circuit breaker closure before taking the relay to the
Reset State from the Reclose Cycle State or the Lockout State. Circuit breaker
status is determined by the SELOGIC control equation setting 52A. See Close
Logic on page 6.2 and Optoisolated Inputs on page 7.2 for more discussion on
SELOGIC control equation setting 52A.
