NOTICE!
Installation must only be performed by authorized and specialized personnel!
The connected device must have a minimum activation time of 20 ms.
CAUTION!
Electrostatic discharge (ESD)! Electronic components could become damaged.
Ground yourself using a wrist strap or take other suitable actions.
DANGER!
Live components and stripped cable! Risk of injury from electric shock.
The system must be current-free during connection work.
Functional description
The FLM-420-RLV1 Relay Interface Module Low Voltage has a change-over contact relay to provide a potential free
output contact.
The FLM-420-RLV1-E type in-built can be flush mounted in standard device boxes in accordance with EN 60670;
alternatively, it can be installed in the devices (see Figure 6 to Figure 7, Page 7).
Address setting
Address setting is carried out using the 8 DIP switches and a suitable pointed object (see Figure 1 to Figure 4, Page 4
and the following tables).
Address (A)
Operating mode
0
Loop/stub in LSN improved version mode with automatic addressing
1 — 254
Loop/stub/T-tap in LSN improved version mode with manual addressing
255 = CL
Loop/stub in LSN classic mode (address range: max. 127)
Connection
