      SUBROUTINE sensor_sens(NSENSOR,SENSOR_TAB,SENS)
C-----------------------------------------------
C   ROUTINE DESCRIPTION :
C   ===================
C   SENS sensor : Starts when IS1 Starts,
C                 Remains active for at least TDELAY
C                 IF IS2 is defined : Stops when IS2 Starts
C                 ELSE Stops after TDELAY.
C                 IS1 and IS2 are the sensors given as definition
