[6] Decode Circuit of Positioning Complete Position No.
The decode circuit converts the binary data of positioning complete position No. sent from
ERC3 and PIO converter to PLC into the corresponding bit data.

This is the timer to prevent the code reading
error since the scanning is held independently
by PLC and RC controller.
[7] Actuator Start Circuit
If the “Operation” switch on the operation box is pushed, the lamp of the “Operation”
pushbutton switch described in (3) Operation and Stop Circuit goes on and, at the same time,
the actuator starts successive positioning of position No. 1o2o3o1o2•••. The circuit below is
intended for the activation.
Because the operation signal remains ON until the
stop button is pushed, pulsed start signal is generated
so that the circuit for moving to the first position (No.1)
may not remain ON. operates next circuit.
