Functional description
The Remotus RX161 receiver uses a dual channel architecture combined with eight (8) safety re-
lays whereof two safety relays are intended for the safety stop. The other 6 safety relays are used
for crane movement and provides protection against unintended movement due to welded relay
contacts (UMFS Category 3 PL d ISO 13849-1:2006).
The dual channel architecture and extensive use of safety relays in the receiver will significantly
increase the safety of the crane system providing that the installation is carried out correctly. To
achieve category 3 Pl d for the STOP function according to ISO 13849-1:2006 both safety stop
outputs from the receiver shall be connected to two independent stop inputs on the crane (two
safety stop channels).
