High-speed counter current value clear
Counts pulses at input relay 0005. When the count value reaches setting value
60000, clears the current value of high speed counter CTH1 and turns ON output
relay 0502 for 3 s.
Ladder diagram Coding
Input of phase differential signal
Inputs phase differential signals to input relays 0004 and 0006 and counts pulses at
CTH0.
Writes the count value into DM0000.
When high speed counter CTH0 reaches 60000, clears the current value of CTH0,
sets output relay 0500, and stops fetching count value to CTH0.
Sets 0008 as external reset.

Note: Initial settings for special utility relays
Sets input time constant of input relays 0000 to 0009 to 10 µs when 2813 turns
ON.
Clears the current value of CTH0 when 2103 turns ON and CTC0 is ON.
Sets CTH0 in the X 2 mode when 2113 is ON and 2114 is OFF.
Enables external reset (input relay 0008) when 2115 turns ON.
