Does the LH4N have a dry contact will open after the unit is finished deceleration?
Only on the LH4N2 units. A normally open seal in / fault relay is provided between terminals 04 and 05. These terminals should be used to keep the line contactor energized after a stop command for the duration of the soft stop ramp or to drop out the line contactor if the soft start module is damaged. The LH4N1 units do not have any provision for external control connections.
