Fortress Interlocks VS Voltage Sensing Unit

The VS unit measures the regenerative voltage produced by a motor and prevents removal of the gate key until the machine has come to a stop.  It is typically used to ensure a trapped key sequence can only begin when the machine has come to rest.  

The VS unit is used where there is a 'run down period' or where the use of an electronic timer would introduce inefficiencies.  The VS unit is housed in a stainless steel enclosure and sealed to IP65.

Direct drive operation - positively opens contacts.Suitable for machines with a run down cycle.Stainless Steel Enclosure, sealed to IP65.Special switch ratings, solenoid voltage and/or contact arrangements available on request.Solenoid monitoring contacts as standard.Permits access as soon as the machine comes to a rest.No additional timer safety margin required.NAMEVS VOLTAGE SENSING UNITPART NO.VSRANGEMechanical Trapped Key Interlocks
