The active green LED means that the module is powered and receiving control power from the Sepam relay. If the green LED is OFF, verify that the CCA77x cable is wired correctly from the "D" port of the Sepam to the "Da" port of the remote module. Also, verify that the Sepam relay is energized, or else the remote module will not receive the power from the Sepam relay.
