What is the state of the ATS48 Fault relay for various conditions?
What is the state of the ATS48 “Fault” relay contact for the following conditions?
Relay R1 functions as a fault relay on terminals R1A-R1C when Menu IO, parameter r1 = r1F.
It is a normally open contact.
Control power not applied to CL1-CL2, contact is OPEN
Control power applied and no fault, contact is CLOSED
ATS48 detects a fault, contact is OPEN
Note special case where Automatic Restart is active, Menu PrO, parameter ArS = ON. When an Auto-Reset condition is detected, the R1 contact will remain CLOSED until all restart attempts are completed. If the fault remains after the last attempt, then the R1 contact will OPEN.
