open and any of the following conditions exist:
(1)
the car-door contact is closed or
the portion of the circuit, incorporating this contact is bypassed;
(2)
the interlock contact of the landing
door that is coupled to the opened car door is closed or the portion of the
circuit, incorporating this contact is bypassed, except when operating during

the car-door contact and the
interlock contact of the door that is coupled to the opened car door are
