The relay releases automatically in case of interruption or short-circuit of proximity switch or cable. Example 2 The relay operates when the proximity switch is inactive or the cable is interrupted. The relay operates in case of short-circuit of proximity switch or cable. SD x70 The set-reset relays SD 170/270 are used with 2 proximity switches in the following way: The relay operates when proximity switch S1 is activated momentarily and subsequently remains on. When proximity switch S2 is activated momentarily or the power supply is interrupted, the relay releases. Power supply SD 110/210 Power supply SD 110/210 Example 1 Power supply SD 170/270 Example 2 Dimensions If both proximity switches are activated at the same time, S2 has priority and the relay therefore releases.
