and T2.
T1 and T2 operate as latched.
T1 and T2 operate as non-latched.

quenching system (eliminator)
control.
N/A in EAFR-110F
S5 fiber sensor channel operates as fiber
loop sensor function.
S5 operates as arc quenching system (elimina-
tor) control. The Tx terminal of the S5 channel
sends a test pulse signal to the quenching
system.
4
Fast / CBFP
Selection of trip relay T2 function.
Trip relay T2 will have 7 ms trip time.
Trip relay T2 will work as CBFP relay. If any sen-
sor or light input (BI2) is activated for more than
the set CBFP time (100 or 150 ms), the CBFP
function activates the trip relay T2 and binary
output BO1.
otee:
N
Master trip command (BI2, see
dipswitch 4) will not activate T2
when in CBFP mode
