O & M Manual for the RLC1

Automatic Transfer Switch

Re-Transfer

Re-transfer is defined as a change of the load connection from the 

Generator to the Utility.

Utility

Utility is the primary source (normal source, normal power source, 

or normal).

Generator

Generator is the secondary source (generator emergency source, 

emergency power source, emergency, standby, or backup 

source).

Utility: Failed or Fails

Utility is defined as “failed” when it is outside of its undervoltage 

setpoint ranges for the nominal voltage and frequency setting.

Generator: Failed or Fails

Generator is defined as “failed” when it is outside of its undervolt-

age/underfrequency/overfrequency (if applicable) setpoint ranges 

for the nominal voltage and frequency setting for a time exceeding 

0.5 seconds after the Time Delay Emergency Fail (TDEF) time 

delay expires.

Transfer

Transfer is defined as a change of the load connection from the 
Utility to the Generator power source.

Unconnected

Unconnected is defined as when the input is not shorted by an 

external contact or connection.
