OR-4 can be operated in two type, open circuit delay relay and automatic restarting relay according to conection method.
① When using as open circuit delay relay
  example of external connection circuit
 
The contact terminals 4, 5, 6 must be connected to have the same electric potential as power terminals 1, 3.

② When using as automatic restarting relay at instantaneous shut-off)

  ¡Ø (Note) -
    MC:magnet contactor)
    PB₁ :push button switch for moving)
    PB₂ :push button switch for stop)
    TB:thermal relay contact)
    When operate from long distance, make circuit connection as ② and verify that MC is
    operating, In long distance operation the effect of catacity between lines can be
    reduced at circuit ¨è. If the distance is above 10mm connect like ② . Avoid pressing PB1
    and PB2 simultaneously, because so doing is the cause of internal circuit abrasion.
 
  time chart (in automatic restarting at moment power-off)
  Operation description(circuit diagram-1)
    Moving -
    If PB2 is pressed, contactor MC become ON due to power voltage between power terminals 2-3 through MCa1.
    If relay X become ON, time delay capacitor C2 is charged through Xa1(C1 is ripple
    filtercapacitor, C3 : for AC110 is for surge absorption and for AC220V is for moment
    return.)
    Power-off -
    If power-off is occur, C2 charged current is discharged by circuit of C2(+)-Xa1-R2-X- ③
    PB2- ① -C2(-) and relay X is maintained until discharge current is below relay retaining
    current. <See circuit diagram-1.>
    Automatic restarting -
    If power return within OR-4 time standard, MC restart automatically by Xa2 because
    relay X is self-retained.
    Moment return (when PB2 is OFF) -
     
    ※ for AC110V
    For AC110V and for AC220V have separate circuit.
    MC is moment returned by PB2 OFF and voltage between ② and ③, ② and ① is
    revomed. but, C2 discharge current pass through C2(+)-Xa1-R2-X- ③ -Power trans -MC-
    Tb- ⑦-④-① -C2(-) Therefore, in AC110V open circuit, there is silicon diode between ⑦ and
    ④ in order to cut discharge current and due to it relay X returned momently.
    The silicon diode inserted between ⑦ and ④ is for moment return of relay X
    <See circuit diagram 1.>
     
    ※ for AC220V
    If you intend to operate for AC220V in te same way for AC110V, you must avoid
    discharge current toward X, and moment return is occur by inserting C3 through contact
    of Xa3 instead of silicon diode.
    Pass AC through relay X by PB2 OFF, R phase-MC-Xa2- ①-Xa3-X-③ -T phase circuit and
    when C2 discharge current and this AC is the same at the T phase polarity, R phase
    polarity, relay returned momently.<See circuit diagram 2.>
 
    If press PB2 at moment return, current pass throguh MC with formed same value <circuit
    diagram 3-4> circuit. In this case, each side voltage(E) of MC need to be below return
    voltage rating value.
    In moment shut-off return, since operated and self-retained by half-wave rectifying
    voltage, relay contactor which can be operated and selfretained by half-wave rectifying
    voltage need to be used.
