(1) For use on other functions, please see the diagrams relating to the single function products.
(2) By external potentiometer, to be ordered separately. If external potentiometer is fitted, the internal potentiometer is
automatically disconnected.
(3) Except control of partial stop of time delay for RE7-MY13BU.
(4) A switch on the front face of the relay allows the second changeover contact to be used in instantaneous mode.
