output 4.
Note (1) If the External Tripping Input (TRG) is enabled for any branch outputs,
those outputs will be cut off within 20 ms when the TRG input is ON for
more than 10 ms.
(2) The shutdown delays specified by the shutdown sequence times will be
applied before disconnecting each output.
(3) When the TRG input goes ON, the seven-segment display will indicate
“TRG.”
(4) Once the TRG input goes OFF, the cut-off branch outputs can be recon-
nected by pressing the Reset Key for 3 s or longer.
(5) When all outputs are cut off simultaneously in Test mode or the shutdown
sequence operation is executed via communications, the branch outputs
will be cut off regardless of the external tripping input setting.
